Carta was valued at $8.5B in a January 2022 secondary sale in which employees sold shares to new investors.

TechCrunch reported in June 2024 that Carta was pursuing a secondary sale at a $2B valuation. Completion and final terms remain unconfirmed; this was a reported sale of existing shares, rather than an announced primary funding round.

The company previously raised a $500M Series G led by Silver Lake in August 2021 at a $7.4B valuation. Earlier rounds included a $300M Series E led by Andreessen Horowitz in 2019 at a $1.7B post-money valuation, with Lightspeed, Goldman Sachs, Menlo Ventures, Meritech, and Tribe Capital participating, and a $17M Series B led by Spark Capital in 2015 with participation from Union Square Ventures. Marc Andreessen joined the board with the Series E.

Henry Ward and K9 Ventures founder Manu Kumar founded the company as eShares in August 2012. It raised $1.8M in seed funding in 2013 from investors including K9 Ventures, Draper VC, and Scott Banister. The company rebranded as Carta in 2017.

Carta is a financial infrastructure platform that digitizes and automates equity management, fund administration, legal services, and private market transactions.

The platform functions as both the legal system of record and operational backbone for private companies managing ownership structures.

Carta replaces traditional paper-based equity management with a real-time digital cap table that updates automatically as transactions occur. For example, when a startup issues new shares to employees or raises a funding round, those changes are reflected directly in the cap table without requiring manual data entry. This is possible because Carta operates as an SEC-registered transfer agent, allowing it to legally issue and track securities rather than maintaining a spreadsheet-based representation.

The platform also supports comprehensive equity lifecycle management. Companies use Carta to conduct 409A valuations for tax compliance, utilizing automated workflows that pull data directly from the cap table to produce audit-ready reports. The total compensation module enables startups to benchmark salaries and equity grants against market data sourced from thousands of companies on the platform.

For investment firms, Carta Fund ERP is a suite of connected products for running the firm and its funds: tracking prospective investments and LP relationships, maintaining fund accounts, collecting portfolio-company financials, valuing investments, preparing taxes, and reporting performance to investors. These products share data across workflows, reducing the need to reconcile separate spreadsheets, accounting systems, and investor portals.

Fund Administration is one product within Fund ERP. It combines software with dedicated fund accountants to maintain the fund’s general ledger, process capital calls and distributions, calculate fund performance, and prepare financial statements and LP reports. For example, a fund manager can request capital from LPs, track their payments, record an investment, and report each LP’s resulting balance through the platform.

Other products handle distinct parts of the investment lifecycle: Deal CRM tracks potential investments, while LP CRM manages fundraising relationships; Portfolio Valuations and Data Collection gather company financials and support investment marks; Fund Tax prepares returns and K-1s; Fund Forecasting models future cash flows and returns; and Loan Operations tracks loan terms, interest, and repayments for private credit funds. Carta’s ListAlpha acquisition expanded its CRM capabilities, adding relationship and deal-management tools alongside its accounting and administration products.

Through the acquisition of Avantia, a London-based SRA-regulated law firm, Carta has launched Carta Law — a legal and compliance services arm focused on routine, high-volume work such as NDAs, KYC checks, investor onboarding, and LP transfers. Avantia's AI workflow engine, Ava, is embedded in the enterprise platform to deliver AI-assisted legal recommendations verified by attorneys and linked directly to fund records and operational workflows.

Carta operates a B2B SaaS model with network effects connecting companies, investors, and service providers in the private markets ecosystem.

The company generates revenue through annual software subscription fees and transaction-based charges for services such as 409A valuations and fund administration.

The primary growth mechanism begins with cap table customers who invite their investors to the platform via free portfolio access. As investors onboard more portfolio companies to Carta, they are increasingly likely to adopt fund administration services to streamline operations. This creates a reinforcing cycle where each new company customer introduces additional investor relationships, and each investor customer drives referrals to new companies.

Pricing is structured to scale with customer growth and operational complexity. Early-stage companies pay lower annual fees for basic cap table management, while costs rise as companies expand, raise larger funding rounds, and require advanced features. Fund administration fees are tied to assets under management and service complexity, resulting in higher revenue per customer from institutional clients.

The business model benefits from high switching costs once customers are integrated into the platform. As Carta serves as the legal transfer agent, switching to a competitor involves re-issuing securities and updating investor records across potentially hundreds of stakeholders. This dynamic supports strong customer retention and allows for consistent price adjustments over time.

Carta has evolved into a hybrid software-plus-professional-services model that spans software subscriptions, transaction-based fees, and outcome-based legal and compliance work. The company employs accountants, lawyers, and analysts to manage complex transactions — and through Carta Law, delivers AI-assisted legal and compliance services such as LP transfers and investor onboarding that are verified by licensed attorneys and billed as an outcome-based service. This structure increases per-customer value and deepens switching costs through integrated workflows that span software, financial operations, and legal execution.

Shareworks by Morgan Stanley is Carta's most direct competitor, serving well-capitalized companies such as Uber, Dropbox, and Stripe. The platform integrates with Morgan Stanley's broader financial services infrastructure to provide wealth management and liquidity solutions that Carta does not independently offer.

However, Shareworks primarily focuses on later-stage companies and has limited presence in the venture-backed startup market, where Carta maintains a stronger foothold.

Traditional competitors like Solium relied on manual workflows that required frequent updates to keep cap tables accurate.

Carta's status as a registered transfer agent enables automatic updates triggered by transactions, creating an event-driven system that reduces administrative overhead and enhances accuracy.

Pulley, previously a prominent challenger positioning itself as a simpler, founder-friendly alternative, announced in September 2026 that it would cease operations on December 8 and partner with Carta to transition customers. Its withdrawal removes a competitor that had targeted dissatisfaction with Carta’s pricing, complexity, and customer service.

Regional competitors such as Ledgy in Europe and Qapita in Asia are gaining traction by offering localized regulatory support and multilingual documentation, areas where Carta's global platform is less competitive.

These companies leverage expertise in local option plan structures and compliance requirements, creating defensible advantages in their respective markets.

Carta’s new-product strategy extends its systems of record into the services and compliance work surrounding each transaction. Start with a service delivered by professionals, automate the work behind it, and connect the output directly to Carta’s records. The company is extending the approach it used in cap tables, valuations, and fund administration into legal services.

Fund ERP expands the products Carta can sell to an existing investment firm, spanning accounting, tax, valuations, forecasting, and relationship management. Acquisitions accelerate this expansion: ListAlpha added CRM capabilities, while Avantia enabled the launch of Carta Law for legal and compliance work such as NDAs, investor onboarding, and LP transfers. Connecting these services to the same underlying records creates opportunities to capture more of each customer’s operating budget.

Carta is expanding beyond venture-backed startups and venture capital funds into private equity, private credit, funds of funds, and institutional LPs. Private equity products support complex ownership structures and distribution waterfalls, while the Sirvatus acquisition added loan operations for private credit managers, including interest calculations, covenant tracking, and repayment reporting.

LP Portfolio Analytics and fund-of-funds workflows extend Carta’s reach to investors allocating capital across multiple funds. Together, these products broaden the customer base from companies issuing equity and VCs investing in them to a wider range of private-market managers and capital allocators.

Carta is extending its platform internationally through acquisitions and local regulatory infrastructure. Its acquisition of Capdesk established a European equity-management business, while Avantia’s SRA-regulated UK legal practice adds a base for serving fund clients with legal and compliance services.

In the Middle East, Carta obtained regulatory approval in Abu Dhabi Global Market and established Hub71 offices to serve the region. Local licensing and support for jurisdiction-specific requirements help Carta bring its products to customers beyond its U.S. base.

Data controversies: Carta's 2024 exit from secondary trading followed allegations of misusing customer data to benefit its own trading operations, eroding trust with key stakeholders. Comparable data governance challenges could weaken the network effects underpinning Carta's competitive position, as investors and companies may hesitate to share sensitive information on the platform.

Market concentration: Carta's revenue growth is closely tied to the performance of venture capital and private equity markets, which have experienced considerable volatility in recent years. A sustained downturn in private market activity could simultaneously reduce demand for cap table management, 409A valuations, and fund administration services, creating correlated revenue risks across its business lines.

Competitive unbundling: Specialized competitors are targeting discrete components of Carta's integrated platform with narrowly focused solutions that may deliver superior functionality in specific areas. If customers increasingly adopt best-of-breed tools over Carta's broader platform, the company could encounter margin compression and customer attrition across multiple product offerings.
