CoinTracker (YC W18) – Cryptocurrency portfolio and tax manager

Hi — we’re Chandan and Jon, co-founders of CoinTracker ( CoinTracker is a cryptocurrency portfolio manager that automatically pulls balances and transactions from top exchanges and wallets, and delivers tax information to users.

We built CoinTracker because, as cryptocurrency investors, we were let down by the existing tools for basic performance tracking of our investments. We started by simply creating a spreadsheet that enabled manual entry of transactions, and eventually hacked away with Google Apps scripts to import prices from various exchanges. This quickly got out of hand, so we built our own tool. We casually told a few friends who are into cryptocurrency about it. They found it as useful as we did, and to our surprise started telling their friends about it. We started receiving a steady stream of feature requests, and since then we have been steadily improving CoinTracker.

One of CoinTracker’s foundational aspects is that balances and transactions are automatically synced from exchanges and cryptocurrency wallets. Before CoinTracker, we hated the idea of manually entering every transaction into a tool. This approach also enables us to calculate cost basis, ROI, capital gains, and other tax-related information for you. There are technical challenges of ensuring that we correctly handle transfers between your wallets and transitively handle cost basis — something that a lot of other tools struggle to do correctly. We think this direction is enabling us to build the best cryptocurrency portfolio tracker with important services like taxes built on top.

We'd love to get feedback from the HN community on CoinTracker and how we can improve. Thank you!
