Carta Review 2026: What Happened After Carta Killed Its Own Secondary Market

Carta manages equity ownership records for approximately 40,000 startups and reported roughly $370 million in combined annual revenue as of early 2024, split across cap table software ($250 million), fund administration ($100 million), and private equity tools ($20 million). By mid-2025, CEO Henry Ward confirmed the company is approaching $500 million in annual recurring revenue and expanding into institutional private equity and credit. What fewer people discuss is what Carta sacrificed to get here: in January 2024, Ward shut down CartaX — the company's private secondary trading desk — after a scandal that exposed a structural conflict of interest baked into fintech infrastructure platforms.

What Carta Actually Builds Today

If you have ever worked at a funded startup or backed one as an angel investor, you have almost certainly touched Carta. The company began as cap-table management software, the digital ledger tracking who owns how many shares, at what price, and under what terms. Today it has expanded into a suite of interconnected private-capital tools.

The core product remains cap-table management: recording equity issuances, tracking option grants, generating shareholder reports, and serving as the official record for share transfers. Carta also runs 409A valuations (independent appraisals of a private company's fair market value, required by the IRS to set the strike price for employee stock options legally), fund administration software for venture capital GPs (general partners, the fund managers who make investment decisions), and LP (limited partner) portfolio analytics for the fund investors who commit capital to those funds.

In 2026, Carta's stated strategy is to build what it calls the "networked ERP for private capital," an enterprise resource planning system connecting companies, funds, and LPs in one data graph. A February 2026 product roadmap published by Carta described the year's focus as "depth, moving beyond simple record-keeping to deliver a real-time, interconnected system of record." New capabilities include LP KYC (know-your-customer identity verification for fund investors), automated K-1 tax document generation, audit confirmation workflows, and AI-assisted equity management tools.

Ward confirmed in a mid-2025 interview that Carta has raised $1 billion across seven funding rounds, with private equity firm Silver Lake among its later-stage investors. The company is growing at more than 20 percent annually, and Ward has identified private equity and private credit as the next growth frontier, estimating PE is six to eight times the size of the venture market Carta already dominates.

Why Switching Is Harder Than It Looks

Carta's dominance is not purely about product quality. Network effects and switching friction lock customers in at a level most enterprise software companies would envy.

The cap table is the legal source of truth for a company's ownership structure. Migrating it requires reconciling years of historical transactions, every stock issuance, option grant, transfer, conversion, and repurchase, against external records, then getting all parties (lawyers, investors, the company's board) to sign off on the result. That process typically costs tens of thousands of dollars in legal fees and takes months. For a Series B startup with a complicated option pool and a dozen institutional investors, the switching cost is enormous.

Carta also creates a data lock at the investor level. When you invest in a startup that uses Carta, your shares and contact information are recorded in Carta's system. The company, not you, controls what Carta does with that data. As the January 2024 scandal demonstrated, that asymmetry matters. Investors in Carta-hosted startups have no direct relationship with the platform and no control over how data about their holdings is handled.

For venture funds using Carta's fund administration tools, the switching friction is similar. Carta holds capital call records, LP commitment data, distribution histories, and K-1 tax documents. Competitors such as Juniper Square, Allvue, and AngelList Stack offer alternatives, but moving an active fund mid-cycle is rarely worth the disruption. Carta knows this, and so does anyone who has tried to leave.

January 2024: The Secondary Market Implosion

Here is what actually happened, based on contemporaneous reporting from TechCrunch, Fortune, Axios, and Business Insider.

In early January 2024, Karri Saarinen, the Finnish CEO of Linear (a project management software startup and Carta customer), posted publicly on LinkedIn that a Carta employee had contacted one of Linear's angel investors to offer to sell their shares through CartaX, Carta's private secondary trading platform. Linear had never consented to any secondary sales process. The investor contacted was a family member whose investment Saarinen says Linear never published anywhere. Saarinen wrote: "They never contacted us (their customer) about starting an order book for Linear shares. The investor they reached out to is a family member whose investment we never published anywhere. We and they never opted in to any kind of secondary sales. Yet Carta Liquidity found their email and knew that they owned Linear shares."

The post went viral immediately. Within hours, other founders reported similar experiences. Business Insider obtained and published unsolicited emails from Carta employees offering shares of multiple startups on CartaX, including Airtable, Deel, Navan, Brex, and Flexport, without those companies' knowledge. At least two of the companies named in those emails were active Carta cap-table customers, meaning Carta held the confidential data used to identify and contact their investors. Business Insider also reported that former compliance and liquidity heads at Carta had previously raised concerns about the conflict of interest and were pushed out after doing so.

CEO Henry Ward initially blamed a single employee who "violated our internal procedures and went out of bounds." But Fortune confirmed that Carta paused all sales outreach company-wide after Chief Revenue Officer Jeff Perry sent an internal Slack message instructing employees to stop sales contact until further notice.

Within roughly 72 hours, Ward published a statement, confirmed by Axios, announcing Carta would exit the secondary trading business entirely. His reasoning was direct: "Because we have the data, if we are trading secondaries, people will always worry that we are using the data, even if we are not. So we have decided to prioritize trust, and exit the secondary trading business." Ward added that he called it his "greatest failure and disappointment." CartaX had generated roughly $3 million in annual revenue, less than 1 percent of Carta's total at the time. Losing the cap table business over it was not a trade-off Carta could survive.

The Structural Problem Every Fintech Investor Should Understand

What makes the Carta story structurally important is not that one employee misbehaved. It is that the conflict of interest was built into the business model from the start, and Ward himself said so.

Any platform that holds confidential ownership data and also operates a marketplace trading on that data faces the same problem. The cap table contains every investor's name, contact information, share count, purchase price, and ownership percentage. That data is extraordinarily valuable to anyone sourcing secondary deal flow: it tells you exactly who owns what, at what cost basis, and how long they have held it. A secondary broker with access to that data has a structural information advantage over every other market participant.

Ward acknowledged this directly: "Having ground truth data is not an advantage if we can't use it. And it is a disadvantage if people think we use it." He also noted that Carta deliberately never released a data product in more than ten years of operation, because the data belongs to customers, not to Carta.

I think this principle extends well beyond Carta. If you are an LP in a fund that uses a platform for fund administration, custody, or performance reporting, and that same platform also runs a secondary market or sells data to third-party buyers, ask three direct questions: Do employees on the marketplace side have read access to LP holding records? Does the compliance function report independently of the revenue team? And is there a written data-wall policy separating the database business from the marketplace? Carta proved these questions are necessary, not hypothetical.

Who Fills the Secondary Market Gap

For founders, early employees, and angel investors who want liquidity in private company shares, several dedicated platforms have stepped into the space Carta abandoned. None of them holds your cap table. That is the key structural difference.

Platform	Model	Best Fit
Forge Global	FINRA-regulated broker-dealer; institutional and accredited investor trading; also offers Forge Price daily valuation data on ~200 pre-IPO companies	Larger institutionally held positions; accredited buyers and family offices
Hiive	Direct marketplace matching buyers and sellers of private company shares; co-founded by former compliance leadership from the secondary space	Angel investors and early employees seeking smaller-lot liquidity
EquityZen	Accredited investor platform for pre-IPO share purchases; structures SPV (special purpose vehicle) access to individual companies	Accredited buyers wanting direct single-company exposure
Nasdaq Private Market	Issuer-sponsored tender offers and structured liquidity programs for later-stage companies	Companies running formal employee liquidity programs; transactions above $50 million

Each of these platforms requires accredited investor status (defined by the SEC as individuals with more than $200,000 in annual income or more than $1 million in net worth excluding a primary residence). Each transaction is subject to the company's right of first refusal and often requires board approval. Private secondary sales are slower and more expensive than public market trades. Plan for a 60-to-120-day process on a realistic deal.

Risks and Limitations Worth Knowing Before You Use Carta

Carta is a genuinely useful product and remains the best-supported cap table tool for most early-stage companies. These are the specific limitations worth understanding before you sign.

Data custody risk. Every investor's contact information, share count, and cost basis sits in Carta's database. The January 2024 incident showed that internal controls can fail even at a company that publicly commits to data separation. Ask your Carta-using portfolio companies what their data-sharing settings are and whether employees outside the cap table team can read their shareholder records.

Pricing opacity. Carta's pricing is tiered and not publicly listed for mid-market or enterprise plans. Multiple founders have reported significant renewal price increases after Carta becomes deeply embedded in a company's legal and financial workflows. Negotiate a multi-year rate lock before signing if you can.

Valuation independence. Carta provides 409A valuations and also manages the cap table that feeds into those valuations. Carta maintains it uses a separate team for 409A work, but the theoretical conflict between appraisal independence and data access is worth understanding if a Carta 409A valuation will affect a pending funding round or an acquisition negotiation.

Data portability friction. Before signing a long-term contract, negotiate data export rights in writing. Specify the format (XLSX and JSON at minimum), the timeline for producing a full export, and whether any exit fees apply. Get this in writing before you need it, not after.

Frequently Asked Questions

Did Carta violate any securities laws when it accessed cap table data for CartaX?

Carta described the January 2024 incident as a breach of internal privacy protocols by a single employee, not a violation of law. No regulatory enforcement action by the SEC or FINRA was publicly announced following the controversy. Whether the conduct violated contractual terms with affected customers was not adjudicated publicly, and Carta did not disclose any subsequent settlements.

Is Carta still the right cap table tool for an early-stage startup in 2026?

For most pre-Series B startups, Carta remains the default choice because lawyers, investors, and transfer agents all know how to work with it and many require it. Competitors such as Pulley and AngelList Stack offer lower-cost alternatives for companies that want to shop on price at the earliest stages, but Carta's network effects are real and switching costs rise sharply once a cap table grows past a few dozen shareholders.

What is the best way to get liquidity in private startup shares if CartaX no longer exists?

Your best options today are Forge Global for larger institutionally held positions, Hiive for angel and early-employee positions in venture-backed companies, EquityZen for accredited buyers wanting single-company exposure via an SPV structure, and Nasdaq Private Market for issuer-sponsored programs at later-stage companies. All require accredited investor status, and all transactions must clear the company's right of first refusal.

How should an LP evaluate whether a fund administrator has a data conflict of interest?

Ask the GP three direct questions: Does the fund administrator operate a secondary trading desk or sell a data product to third-party buyers? Do employees on the marketplace side have read access to LP holding records? Does the compliance function report independently of the revenue team? A no, no, and yes to those three is the right answer.
