Carta vs Shareworks: Which Equity Platform Fits Your Stage in 2026?

Updated August 2026

If you've landed on this comparison, there's a decent chance you're not actually choosing between Carta and Shareworks the way you'd choose between two CRMs or two project trackers. More often, someone asks "should we be on Shareworks by now?" after years on Carta, or a public company evaluating equity administration vendors puts Carta on the list out of habit and gets told, gently, that it's not really built for what they need next. This comparison is for founders, CFOs, controllers, and stock plan administrators trying to figure out which situation they're actually in.

That's because this is a stage comparison more than a feature comparison. Carta is where venture-backed companies start: it's the default cap table for seed and Series A companies, and it stays useful well into growth stage. Shareworks, now sold under the Morgan Stanley at Work brand, is where companies with large distributed employee populations, ESPPs running at real scale, and public-company ambitions (or public-company status already in hand) tend to end up. The two platforms overlap on paper (both manage equity, both run 409A valuations, both handle RSUs and options) but they were built for buyers at opposite ends of the same journey, and that shows up in almost every section below.

TL;DR

Key Facts

• ESOPs alone cover 15.1 million participants across 6,411 companies in the United States, holding more than $2 trillion in combined assets, according to the National Center for Employee Ownership's most recent Department of Labor data (NCEO).
• 57% of public companies now offer an employee stock purchase plan, but the median participation rate among eligible employees sits at just 38%, per the NASPP/Deloitte Tax Equity Incentives Design Survey (NASPP).
• US venture capital deployed $320 billion across 15,352 deals in 2025, and every one of those financings created or updated a company cap table, according to the NVCA 2026 Yearbook (NVCA).
• Startups on Carta's own platform raised nearly $120 billion in new funding in 2025, up almost 17% from 2024, per Carta's State of Private Markets: 2025 in Review (Carta).
• Carta administered 71 tender offers with roughly $3 billion in combined transaction volume in the first half of 2026 alone, the highest H1 figures in at least six years, according to Carta's own data desk (Carta).

Who Each Platform Is Really For

Both platforms sell "equity management," but the buyer who gets real value out of each one looks very different, and the gap comes down to headcount, geography, and where the company sits in its lifecycle.

Carta's natural buyer is a founder or finance lead at a venture-backed company that just raised a round, needs a 409A valuation on file, and wants option grants, vesting, and the cap table itself living in one product without a procurement cycle. That buyer can sign up for the free Launch tier, be looking at a working cap table the same day, and only talk to a Carta salesperson once the company outgrows the free plan's 25-stakeholder ceiling.

Shareworks' natural buyer looks nothing like that. It's a stock plan administrator, equity compensation manager, or finance systems owner at an organization, often public or planning an IPO, with hundreds or thousands of plan participants spread across multiple countries, running RSU vesting, ESPP enrollment windows, and option exercises at a volume where a self-serve product would buckle. There's no free tier to test-drive; every relationship starts with a sales conversation, which itself signals the scale of company Shareworks expects to be talking to.

A quick way to sanity-check which profile you're actually in:

If your company just raised a round and needs a cap table this week, Pulley and Carta are both built for exactly that moment; Shareworks generally isn't in that conversation yet.

Cap Table Management Depth

Cap table management is the one category where both platforms genuinely compete, but the depth and audience differ.

Carta's cap table is the product it's most known for: real-time ownership tracking, waterfall and scenario modeling, dilution analysis across funding rounds, and investor-facing views that let VCs check their ownership stake without emailing the finance team. It's built to be touched constantly, by founders modeling a new round, by investors checking their position, and by finance leads reconciling grants against the model.

Shareworks' cap table module exists too, listed among its named product lines alongside Equity Administration and Financial Reporting, but it's built to sit underneath a much larger administration workload rather than to be the daily-use modeling tool a founder opens between board meetings. It's less about "what does my next round do to my ownership" and more about "does every one of our thousands of grants across every entity reconcile correctly."

409A Valuations

409A valuations are where Carta built one of its clearest reputational moats. A large share of the private-company 409A market runs through Carta, and the product ships as a high-volume, largely standardized offering built to turn around quickly for companies that need a defensible fair market value on file before granting options.

Shareworks lists 409A Valuations as one of its named product lines too, but the buyer profile is different: it's positioned for organizations that are typically larger, often already inside the Morgan Stanley relationship for other reasons, rather than the high-volume, self-serve-adjacent flow Carta built its reputation on.

Equity Plan Administration vs Full-Service Administration

This is a real, meaningful distinction, not just different marketing language for the same thing. "Equity plan administration" (Carta's frame) means the software runs the mechanics: grants, vesting schedules, exercises, and cap table updates, largely self-service for the company operating it. "Full-service administration" (closer to how Shareworks positions itself for larger clients) means more of the operational and compliance burden sits with the vendor's own team, not just the software.

Shareworks' own product naming makes this explicit: Equity Administration, Financial Reporting, Participant Experience, and Forms Filing are listed as distinct product lines, which signals a vendor built to own more of the operational surface area, not just hand a company a tool and let its own team run everything through it.

Laid out side by side, the named product surface each vendor sells looks like this:

ESPP and RSU Handling

RSUs are core to both products, but ESPPs are where the gap between "startup tool" and "public-company infrastructure" shows up most clearly, because ESPPs are mostly a public-company mechanism in the first place.

Carta administers RSUs and stock options as part of its core cap table and equity management flow, appropriate for private companies where RSUs are increasingly common but ESPPs are rare (ESPPs need publicly tradable stock to make the "purchase at a discount, then sell" mechanic work). Shareworks, built from the public-company side of the market, handles ESPP enrollment windows, purchase periods, and disqualifying-disposition tracking as a first-class capability, alongside the RSU tracking (vesting dates, quantities, and documents) that both platforms support.

If ESPP payroll deductions are part of what's driving this evaluation, it's worth checking how your payroll platform itself handles equity-linked withholding; our best payroll software guide covers that ground separately.

Participant Experience and Support

Both vendors put real effort into the employee-facing side of the product, since a confusing participant portal generates support tickets and, worse, mistrust in the equity itself.

Carta's participant experience is built for the private-company employee: viewing a grant, understanding a vesting schedule, and eventually exercising options, often for the first time in that employee's career. Shareworks names Participant Experience as one of its own product lines, and it's built for a different kind of employee: someone who may be juggling RSU vesting, ESPP enrollment, and (post-IPO) actual open-market trading of shares they already own, often across a global workforce with different tax rules by country.

Global Mobility and Multi-Country Tax

This is one of the widest gaps between the two products, because it tracks directly to company size and geographic footprint.

Shareworks' Global Intelligence application is built specifically for this problem: a comprehensive resource covering tax and regulatory information across more than 150 jurisdictions, kept current by a network of global providers, covering exchange control requirements, translation requirements, and securities law filings that change by country and by plan type. That's the kind of infrastructure a company only needs once it has meaningful headcount outside its home country holding equity.

Carta supports global participants too, but it isn't the product's center of gravity. Most Carta customers are US-headquartered venture-backed companies with a smaller, growing footprint of international employees, not multinational organizations running equity plans across 150-plus jurisdictions simultaneously.

If your company's equity footprint is more European than global, Ledgy is worth a look too; it's built with European reporting and multi-jurisdiction depth as a starting point rather than an add-on.

Brokerage, Transfer Agent, and Liquidity

This section is where the two companies' underlying business models diverge the most, and it's worth understanding both, because it shapes what happens to shares after they vest or get exercised.

Carta is itself a transfer agent, registered with the SEC under Section 3(a)(25) of the Securities Exchange Act of 1934, and its CartaX platform facilitates private secondary transactions, including tender offers and auction-based deals, for companies still private. But for public company transfer agent work specifically, Carta refers clients to Odyssey Transfer and Trust Company as its exclusive partner, which tells you plainly where Carta sees its own center of gravity: private markets, not public-company share registry work.

Shareworks sits inside Morgan Stanley's brokerage infrastructure directly. Participant stock plan accounts are serviced through Morgan Stanley Smith Barney LLC, and Morgan Stanley has been migrating those accounts onto E*TRADE from Morgan Stanley, giving participants a built-in path from vested shares to an actual brokerage account where they can hold, sell, or transfer those shares without leaving the Morgan Stanley ecosystem. For a public company's employees, that's a meaningfully different experience than a private company's employees holding illiquid shares with no trading venue at all.

Compliance and Reporting

Both platforms take equity compliance seriously, but the specific obligations they're built around differ by company type.

On the private-company side, Carta's compliance tooling covers the mechanics private companies actually need: Rule 701 disclosure management (sending and tracking the required disclosures to award holders once a company crosses Rule 701's exemption thresholds), automatic generation of Form 3921 for every ISO exercise, and ASC 718 and US GAAP reporting support, delivered separately from the 409A valuation itself since tax guidance under Section 409A and accounting guidance under ASC 718 have been diverging.

Shareworks covers the same underlying accounting standard, ASC 718, but from the public-company angle: stock-based compensation expense has to be recognized and disclosed in every quarterly 10-Q and annual 10-K filing once a company is public, with no funding-stage threshold or exemption to grow into. Forms Filing is listed as its own named Shareworks product line, and Financial Reporting is positioned around audit-ready output delivered in real time, the kind of reporting cadence a public company's controller and auditors expect.

Once stock comp expense is calculated, it still has to land somewhere in the books; our best accounting software guide covers how that ASC 718 number typically flows into the general ledger and the close process.

Integrations with HRIS and Payroll

Integration depth is a useful proxy for which stack each vendor expects its customers to already be running, and the pattern here tracks the startup-versus-enterprise divide closely.

Carta's HRIS and payroll integrations lean toward the tools a venture-backed startup is actually using: native connections with platforms like Gusto and Rippling support cap table updates and option exercise workflows without manual data entry, which fits a lean finance team that doesn't have a dedicated systems administrator.

Shareworks integrates with the HRIS and payroll systems large, often public companies run: Workday, ADP, and SAP SuccessFactors are named integration partners, with a Workday API enabling flexible file imports and real-time data sharing, so that a change in an employee record inside Workday flows through to equity administration automatically. That's infrastructure built for a company with an established HRIS team, not a startup wiring up its first payroll provider.

If you're also re-evaluating the HRIS itself as part of this decision, our best HR software guide is a useful parallel read.

The Pricing Opacity Trade

Here's the part most third-party roundups get wrong, and it's worth being direct about it: neither Carta nor Shareworks publishes a usable price for its paid tiers, and any dollar figure attached to either vendor on a review site, a listicle, or a rival's comparison blog is an estimate, not a confirmed number. Reprinting one of those figures as a "starting price" would make this article less accurate, not more useful, so we're not doing that.

Carta publishes only its free Launch tier: up to 25 stakeholders and $1M raised, at no cost. Build (up to 50 stakeholders), Grow, and Scale (both with flexible stakeholder limits) all exist as named tiers with feature lists, but Carta's own pricing FAQ states plainly that each paid package is priced per stakeholder against a minimum annual fee, and every paid-tier button routes straight to a sales conversation. Third-party sites print conflicting numbers for what a paid Carta plan actually costs; none of them is Carta itself, so none of them belongs in this article.

Shareworks goes a step further and publishes no pricing at all, not even a free tier to anchor against. There's no self-serve signup path; every relationship starts as a sales-led conversation, which is consistent with everything else about how the product is built and sold.

The practical consequence is straightforward: Carta can be evaluated in an afternoon. You can create a free Launch account, see the actual cap table product, and get a real sense of the interface before a single sales call happens. Shareworks cannot be evaluated that way at all; there's no version of the product you can see without first entering a procurement cycle.

Questions worth bringing into a Shareworks quote conversation: how many countries will hold participants in year one, whether Financial Reporting and Forms Filing are bundled or billed as separate lines, and whether brokerage access through Morgan Stanley Smith Barney and E*TRADE is included or a separate arrangement. Questions worth bringing into a Carta paid-tier conversation: what your actual stakeholder count will be a year from now, not just today, since that's the number the per-stakeholder pricing scales against, and which of the extra capabilities in Grow or Scale you'll actually use versus what you'd be paying for and not touching.

If a Carta quote comes back higher than you expected, our own best Carta alternatives roundup already covers 13 vendors with real, published pricing, including Pulley, which publishes flat annual pricing starting at its Startup tier instead of routing every plan through a sales call.

Implementation Weight and Migration

Neither vendor publishes a single implementation-duration figure, and the reason tracks directly back to how differently the two products are built and sold.

Carta's implementation weight scales with company complexity, but for most customers it's genuinely light: create a Launch account, import the cap table (often from a spreadsheet or a prior tool), and start issuing grants. Moving up to Build, Grow, or Scale adds configuration around 409A cadence, more stakeholder types, and deeper compliance tooling, but there's rarely a multi-month rollout the way enterprise software often requires.

Shareworks implementation is a different order of project. Standing up Global Intelligence across dozens of jurisdictions, wiring a Workday or ADP integration, configuring Forms Filing and Financial Reporting for a public company's audit cycle, and migrating thousands of existing participant records from a prior system all take real time and, typically, a dedicated project team on both sides. That weight is the direct cost of the depth described in every section above; it isn't a flaw so much as the natural result of the scope.

Downstream of implementation, the expense forecasts both platforms produce usually feed into a broader planning process; our best FP&A software guide covers the tools finance teams use once that data needs to flow into a model.

Scale Ceiling on Each Side

This is where the two products stop competing for the same buyer entirely, and it's the cleanest way to summarize the whole comparison.

Carta scales comfortably from a two-founder company on the free Launch tier through late-stage private companies with meaningful headcount and multiple funding rounds behind them, and CartaX gives even large private companies a structured way to run liquidity events without going public. Where Carta's model shows real strain is at true multinational, public-company scale, exactly the point at which Carta itself refers customers elsewhere for transfer agent services.

Shareworks' scale ceiling, by contrast, is effectively theirs to define, since it was built from the top of the market down. Its practical floor is higher than its ceiling is a concern: a fifteen-person startup would be taking on far more platform, process, and sales overhead than it needs, in the same way a small team would be over-provisioned on almost any enterprise software built for a Fortune 500 buyer.

When Carta Is the Right Call

• You're pre-Series A and need a working cap table today. The free Launch tier gets you a real product, not a demo, and it's the fastest way to get option grants and a cap table in order after a first priced round.
• 409A valuations are a recurring, predictable need. Carta's high-volume 409A business is one of its strongest, most tested capabilities, and having it live inside the same product as the cap table keeps valuations and grants in sync.
• You expect to need private secondary liquidity before an IPO. CartaX gives founders and long-tenured employees a structured way to sell some shares without waiting for a public listing that may be years away.
• Your finance team is lean and wants direct control. Carta's self-service model fits a company where a controller or finance lead runs equity administration directly, rather than handing significant operational scope to a vendor's team.

When Shareworks Is the Right Call

• You're public, or close enough that it's the realistic near-term plan. ASC 718 expense recognition and 10-Q/10-K disclosure aren't optional once you're public, and Shareworks' Financial Reporting and Forms Filing lines are built directly around that obligation.
• Your workforce spans dozens of countries. The Global Intelligence application's coverage of 150-plus jurisdictions is exactly the kind of infrastructure a purely domestic cap table tool was never built to provide.
• ESPP administration at real scale is the actual project. If enrollment windows, purchase periods, and disqualifying-disposition tracking across thousands of participants are the problem you're solving, Shareworks was built around that mechanic from the public-company side of the market.
• You want brokerage access built into the same relationship. Participant accounts routed through Morgan Stanley Smith Barney and E*TRADE from Morgan Stanley give employees a direct path from vested shares to an actual trading account, without a separate brokerage relationship to stand up.

If Shareworks' enterprise scope is more than your team needs today, our best Shareworks alternatives roundup covers lighter platforms built for companies that aren't at full public-company scale yet.

Decision Framework

What to Do Next

1. Name your actual stage, not your aspirational one. If you're privately held with a domestic-heavy cap table, Carta's model fits what you need today. If you're public, filing soon, or running equity across dozens of countries, Shareworks' scope matches the real obligations you're carrying.
2. Count your countries, not just your headcount. A 500-person company entirely in one country has very different needs than a 150-person company spread across 20. Global Intelligence's 150-plus jurisdiction coverage only pays for itself once that footprint is real.
3. Check whether ESPP is actually in scope. If there's no employee stock purchase plan, or none planned before an IPO, a meaningful share of Shareworks' built-for-public-companies depth won't be doing work for you yet.
4. Ask both vendors what actually drives their number. For Carta, that's tier plus stakeholder count. For Shareworks, that's participant count, country footprint, and which product lines (administration, reporting, brokerage, valuations) you're bundling into one relationship.
5. Get a written quote scoped to your real inputs before it goes into a budget request. Neither vendor publishes a price, so the only honest comparison is two written quotes built from your actual stakeholder or participant count, not a range pulled from a third-party site.

If the wait for two quotes is the sticking point, our equity management software roundup covers the platforms that do publish a price, and the cap table software roundup does the same for the ownership-record layer.
