CoinTracker

Market position

The company positions itself as the leading crypto tax software; Y Combinator describes it as "the gold standard in cryptocurrency portfolio tracking and taxes," and the founders' 2026 Nino launch post calls CoinTracker "the market leader in crypto tax." At the time of its Series A, the company said over 3% of the global cryptocurrency market was tracked on CoinTracker.

Automated multi-wallet and multi-exchange syncing with transfer matching and cost-basis tracking, direct integration with mainstream consumer tax filing software, exclusive partner status with Coinbase, support for coins, tokens and NFTs, and early support for the full IRS Form 1099-DA lifecycle including reconciliation.

Technology

The platform automatically imports transactions via exchange APIs and wallet addresses, tracks transfers between a user's accounts, keeps balances updated in real time, identifies cost basis and calculates proceeds on individual transactions, and generates tax forms. It supports CSV import (including a CoinTracker-formatted CSV) as a fallback when an exchange API is unavailable, wallet archiving that zeroes reported balances while preserving transaction history and cost basis, and an automatic "defunct" state for known bankrupt or shut-down exchanges. Integrations include TurboTax and H&R Block for e-filing, and coverage spans coins, tokens and NFTs across major exchanges. A mobile app is also offered.

Go-to-market

Self-serve online signup with a free tier, distribution through exchange and tax-software partnerships (the site identifies CoinTracker as an official and exclusive Coinbase partner and highlights an endorsement from Coinbase CEO Brian Armstrong), integrations with TurboTax and H&R Block, a mobile app, and content/support resources plus customer reviews on Trustpilot.

Individual cryptocurrency holders and traders — including high-transaction-volume users — as well as businesses and accountants/CPAs who need portfolio tracking and tax reporting; support content on bankruptcy write-offs and lost funds is scoped specifically to US customers, while the help center is also published in German, Spanish and Italian.

Geography

Headquartered in San Francisco, California, with Y Combinator describing a globally distributed team. Product and tax guidance are heavily US-focused (IRS forms, 1099-DA, TurboTax and H&R Block e-filing), while the support center is offered in English, German, Spanish and Italian.

History

Founded in 2017 and part of Y Combinator's Winter 2018 batch. The company announced six new industry partnerships and passing 100,000 users in 2020, added crypto tools with CCH Axcess and ProSystem fx (reported 2021), appointed Vera Tzoneva as Chief Operating Officer in September 2021, and announced a $100M Series A in January 2022 followed by hires of a Head of Engineering (January 2022), Head of Finance (March 2022) and public statements about continuing to hire through the recession (July 2022). CEO Jon Lerner was recognized as a Top 25 Cryptocurrency Executive of 2022. More recently the founders launched Nino, a separate AI-plus-human financial planning service, in beta.

Risks & controversies

No controversies are described in the available sources. Business-relevant risks reflected in company materials include dependence on exchange API availability (exchanges that shut down, go bankrupt, or withdraw API access require manual CSV reconstruction) and regulatory change, notably the introduction of IRS Form 1099-DA, which the company warns could cause users to over-report tax owed if not reconciled. The company also states it does not provide tax advice.
