Carta dominates startup equity management with cap table software, 409A valuations, and secondary market tools. Our honest 2026 review covers it all.
Not necessarily. Pre-seed companies with very simple cap tables — typically just founders and perhaps one or two angels — can maintain accurate records with a spreadsheet and attorney oversight. Carta becomes strongly recommended when you close your first institutional round with preferred stock, when you begin issuing option grants to employees, or when your cap table includes SAFEs and convertible notes requiring ongoing conversion modeling. At that point, the automation and accuracy of Carta's platform justifies the cost relative to manual maintenance risk.
A 409A valuation is an independent appraisal of a private company's common stock fair market value, required by Section 409A of the Internal Revenue Code before granting stock options. Companies must grant options at or above the 409A-established FMV to avoid tax penalties for employees. Carta provides integrated 409A valuations because their analysts already have access to your complete cap table and financing history within the platform, reducing data transfer errors and streamlining the revaluation process compared to using a separate valuation firm.
Yes. Every employee with equity grants receives access to a personal Carta account showing their grants, vesting schedule, and estimated value based on the most recent 409A valuation. The portal displays vested versus unvested shares, exercise windows and deadlines, and tax implications for different exercise scenarios. Companies can control how much detail is visible to employees, including whether to show the estimated value or only show the grant mechanics. Most companies choose full visibility as a tool for equity compensation transparency and employee retention.
Yes, Carta provides data export capabilities including cap table exports in CSV and Excel formats, and the company's terms of service guarantee data portability. However, transitioning away from Carta in practice involves more than data export — the equity transaction history, document archives, and 409A reports need to be migrated to a new platform. The major Carta competitors (Pulley, LTSE Equity) offer migration assistance for incoming customers. The migration is most straightforward when done between financing rounds rather than during an active process.
For pre-seed and seed companies without institutional investors actively expecting Carta, Pulley is a compelling choice. Pulley offers similar core cap table functionality — option grant management, 409A integration, employee portal — at significantly lower pricing, with a clear migration path to Carta if needed later. The decision point for many founders is Series A: if your lead investor specifically requests Carta or uses Carta's portfolio tools, the migration at that stage is worthwhile. For founders concerned about Carta's 2023 data governance controversy, Pulley also provides a principled alternative.

Carta is the dominant platform for startup equity management, serving over 40,000 companies and more than 2 million employees and shareholders who hold equity. Founded in 2012 by Henry Ward and Manu Kumar, Carta started as eShares — a solution to the paper stock certificate problem in private markets — and has grown into a comprehensive equity infrastructure platform covering cap table management, 409A valuations, equity plan administration, scenario modeling, secondary market transactions, and fund administration.
Carta's market position is exceptional. For Series A and later-stage companies, Carta is effectively the industry standard — investors, lawyers, and secondary market participants have built workflows assuming their portfolio companies use Carta. This network effect creates powerful switching costs that competitors have found difficult to overcome.
In 2026, Carta continues expanding its platform across private market infrastructure including secondary trading infrastructure, fund administration for venture firms, and cross-portfolio equity analytics.
Carta's cap table management module is the foundation of the platform and handles every instrument in a startup's ownership structure:
The cap table updates automatically when any equity transaction occurs — new investment rounds, option exercises, secondary transfers, conversions. This automatic maintenance is what makes Carta's cap table valuable: it is always current without manual reconciliation.
For complex transactions like SAFE conversions on a priced round, Carta handles the dilution calculations automatically, generating updated cap tables with investor confirmation workflows. This reduces what was once a multi-day lawyer-and-spreadsheet exercise to a same-day managed process.
Section 409A of the Internal Revenue Code requires private companies to obtain independent appraisals (409A valuations) to establish the fair market value of common stock before granting stock options. Granting options below the 409A-established FMV creates significant tax penalties for employees and legal exposure for the company.
The 409A requirement creates a recurring need — revaluation is required at least annually and after any significant financing event. Carta provides 409A valuations as an integrated service:
How Carta's 409A works:
Having 409A valuations integrated with cap table management means the valuation analyst already has access to your complete financing and dilution history without data transfer or manual compilation. This reduces the risk of valuation errors from incomplete information.
Carta's equity plan administration module manages the complete option grant and RSU lifecycle:
Grant workflow: Creating a new option grant in Carta takes approximately five minutes — specify the employee, grant type, number of shares, vesting schedule, and exercise price. Carta generates the grant agreement, routes it for board approval if required, and delivers it to the employee for e-signature — all within the platform.
Employee equity portal: Every employee with equity gets access to a personal Carta account showing their grants, vesting schedule, current estimated value (based on the most recent 409A), and exercise windows. The portal provides a tax overview including projected ordinary income and capital gains tax implications for different exercise scenarios.
Exercise processing: When employees exercise options, Carta manages the transaction documentation, payment processing (if applicable), and cap table update automatically. Exercise elections flow through a compliance review to catch inadvertent early exercises or exercises outside permitted windows.
Tax reporting: Carta generates and files required tax forms — 3921 for ISO exercises, 3922 for ESPP transfers — and coordinates with the company's payroll provider for any required withholding.
Termination modeling: When an employee with unvested equity departs, Carta calculates unvested shares, post-termination exercise windows, and repurchase rights. The termination processing workflow ensures all equity obligations are resolved correctly.
Carta's scenario modeling tools operate on the live cap table, eliminating the error-prone practice of maintaining parallel spreadsheet models:
Dilution modeling: Model the impact of a new financing round — specify the pre-money valuation, round size, and option pool expansion, and Carta calculates the resulting ownership percentages for all existing shareholders with full dilution.
Waterfall analysis: For any specified exit value (acquisition price, IPO valuation), Carta calculates the proceeds each shareholder class receives after applying liquidation preferences and participation rights. This analysis is standard in board presentations and investor conversations about exit scenarios.
Option pool modeling: Model the impact of expanding the option pool and understand the dilution implications for existing shareholders before proposing the expansion to your board.
Secondary modeling: Model the impact of secondary transactions — founder liquidity sales, tender offers — on the cap table and individual shareholder positions.
Carta CartaX is the company's secondary market infrastructure for private company equity. Features include:
Secondary market access has become increasingly important as startup liquidity timelines have extended. CartaX provides a managed path to employee liquidity without requiring a full company exit.
In early 2023, Carta faced significant criticism and lost several notable customers over its handling of data about shareholder equity. Specifically, concerns arose about Carta using non-public cap table data from its platform to inform its own secondary trading activities — a conflict of interest that received significant coverage in the startup press.
Carta's CEO Henry Ward publicly acknowledged the concerns, shut down the relevant secondary market activity, and implemented revised data governance policies separating the cap table management and secondary market businesses.
It is important for prospective Carta customers to understand what changed: Carta implemented formal data separation policies, hired a Chief Privacy Officer, and published revised terms of service governing how customer data can be used. The relevant secondary trading activity was discontinued. These changes have been broadly accepted by the startup community, though some companies — particularly those with sensitive fundraising situations — elected to move to competitors like Pulley as a direct result of the controversy.
For the majority of Carta's existing customer base and new customers in 2026, the updated policies are considered adequate. The incident is worth noting as part of due diligence, particularly for companies with sensitive cap table information.
Carta's pricing is based on company stage and complexity:
409A valuations are priced separately — typically $1,500-$4,000 for initial valuations, with subsequent annual revaluations at a discount for existing Carta customers.
Note that Carta's pricing has increased significantly since its early years, and Scale-tier pricing for Series B+ companies can be substantial. The annual negotiation is worth engaging in — Carta has historically provided competitive pricing to retain customers at risk of churning to Pulley.
Pros:
Cons:
Carta vs Pulley: Pulley is the most direct Carta competitor, with similar core cap table functionality at meaningfully lower pricing. Pulley is an excellent choice for pre-seed and seed companies that want to avoid Carta's cost until they genuinely need Carta's ecosystem advantages. Some companies switch from Pulley to Carta at Series A specifically for the investor and secondary market ecosystem. The 2023 controversy accelerated Pulley adoption among founders concerned about data governance.
Carta vs LTSE Equity: LTSE Equity offers a clean, lower-cost alternative with strong 409A integration. Like Pulley, it serves the earlier-stage market well and offers a clear migration path to Carta if needed.
Carta vs Spreadsheets: Pre-seed companies with fewer than five shareholders and a simple cap table can reasonably maintain a spreadsheet cap table with attorney oversight. The switch to Carta makes sense at the first external investment round or when option grants begin — at that point, the complexity exceeds what a spreadsheet can reliably manage.
Carta's market position, ecosystem integration, and feature depth make it the standard choice for funded startups managing equity complexity. The pricing premium is justified for Series A and later companies; earlier-stage companies should consider Pulley until the ecosystem requirements become relevant.
Rating: 4.3 / 5
The 0.4 rating reduction reflects the 2023 data controversy, high pricing relative to competitors, and customer support inconsistencies — all real factors that do not eliminate Carta's value but represent genuine costs of the platform.
