Koinly started as a weekend project by someone annoyed at his own spreadsheet. Robin Singh, a developer and crypto investor, could not find a tool that handled crypto tax reporting better than the manual workbook he was maintaining himself, so he built one — reportedly reaching a working product within four months of starting in 2018. The framing on the company's own about page has not changed since: crypto taxes shouldn't require a finance degree. That origin explains a great deal about the product, which is unusually focused on the specific mechanical problem of getting scattered transaction data into a shape a tax authority will accept, and unusually indifferent to everything else.
The mechanism is straightforward and the coverage is the moat. Users connect exchanges via API, add wallet addresses and blockchains, and Koinly reconstructs the full transaction history, classifies each event, calculates capital gains and income, and generates a country-specific report. The integration count is the headline number — the company claims support for several hundred exchanges, wallets and blockchains, with the figure quoted between 800 and 900 depending on the source — and the event coverage extends well past spot trading into DeFi transactions, staking rewards, liquidity pools, NFTs, mining and airdrops, which is where most competing tools break down. Reports are produced for more than 20 tax jurisdictions with local rules encoded per country, including US forms such as 8949 and the newer 1099-DA, and outputs export into TurboTax, TaxAct and Xero. Accountants are a significant customer segment alongside individual investors, and larger crypto businesses use it too.
The company is unusual in this directory for how little of its structure is public. Koinly is generally described as London-headquartered, operating through a Singapore entity, with a distributed team; published employee counts vary wildly across data providers, which is a fairly reliable sign that none of them know. Funding is similarly opaque — a single round is recorded, with KuCoin Labs named among investors, and no disclosed amount or valuation. There was a round of staff cuts reported in December 2022, at the bottom of the crypto winter and immediately before tax season, which is the one visible data point about the business running lean through the cycle. The user base is described as several hundred thousand.
What matters more than the corporate opacity is the regulatory ratchet the company now sits on. Since 1 January 2026, DAC8 and the OECD's CARF framework require crypto-asset service providers across the EU to report customer transaction data directly to tax authorities. The era of crypto taxes as voluntary compliance is over: tax offices now receive the data automatically, and the reconciliation burden falls on the individual. That is a structural tailwind for every serious tool in this category, and it sharpens the competitive question. Koinly's position is breadth — the most integrations, the widest jurisdictional coverage, a global rather than regional footprint — against Blockpit, which competes on depth of local tax law in the German-speaking markets and has consolidated two European rivals to get there. Koinly is the generalist; Blockpit is the specialist. Which wins probably depends on whether a user's problem is "I traded on eleven venues across four chains" or "I need this to survive scrutiny from the Austrian tax office."
