Reignfall Limited (operating as Koinly)

To bring clarity, accuracy, and compliance to every crypto investor by simplifying crypto taxes and asset tracking.

Koinly helps crypto investors around the world make sense of complex portfolios and tax obligations across chains, wallets, exchanges, and DeFi protocols. Founded in 2019, the platform serves over 2 million users in 140+ countries by automatically importing transaction data from 1,000+ exchanges and wallets to calculate capital gains, losses, and crypto income. Users can generate tax reports compliant with regulations in over 140 jurisdictions, covering everything from simple trading to complex DeFi activities like staking, liquidity provision, and NFTs. The company maintains a 4.6/5 Trustpilot score and positions itself as the solution for investors who want to avoid manual spreadsheet work and reduce tax errors through automated tracking and calculations.

Products

The core product is automated crypto tax reporting software that integrates with over 1,000 exchanges, wallets, and blockchains. Koinly imports transaction data to track capital gains, losses, and crypto income, then generates country-specific tax reports including Form 8949 and 1099-DA outputs for TurboTax, FreeTaxUSA, or direct filing. Beyond tax compliance, the platform offers real-time portfolio tracking, profit and loss monitoring, and tax loss harvesting tools. For businesses, Koinly provides crypto bookkeeping features that sync with traditional accounting software like Xero and QuickBooks. The platform is free for portfolio tracking and tax previews, with users only paying when exporting finalized reports.

Funding

Koinly is entirely self-funded with no external investors or venture capital backing. The company explicitly maintains this independence to avoid investor pressure and focus solely on product development and user experience without hidden agendas. This financial autonomy has allowed the team to grow the user base to over 2 million individuals while maintaining a lean, global operation focused on long-term user value rather than short-term investor returns.

Recent news

In March 2026, Koinly announced a major partnership with the SwissBorg platform, establishing Koinly as their preferred crypto tax partner and providing exclusive tax reporting discounts to the SwissBorg community. Additionally, in May 2026, Koinly’s CEO Robin Singh publicly addressed the state of U.S. crypto adoption, arguing in an op-ed that the nation’s outdated and complex tax code remains a more significant barrier to widespread cryptocurrency integration than regulatory uncertainty itself.

Technology

Built on a focused Ruby on Rails backend with PostgreSQL handling billions of blockchain transactions and over 1,000 integrations. The frontend uses TypeScript and React, with React Native for mobile. The architecture prioritizes high-performance code, query tuning, and efficient data ingestion pipelines over complex overhead. Engineers work extensively with blockchain protocols, on-chain data, API integrations, and JSON responses to process transaction data from exchanges, wallets, and DeFi protocols across multiple chains including Bitcoin, Ethereum, and Solana.

Benefits

Fully remote-first and async-first culture with minimal meetings and truly flexible working hours capped at 40 hours per week. Team members get 32 paid days off annually (including public holidays), a co-working space budget if desired, and a home office stipend since the company doesn't provide equipment. Employment is structured as B2B contracts. The environment emphasizes autonomy, deep work, and clear written communication over corporate bureaucracy. While no company-wide retreats are organized, local informal meetups are encouraged for team members in the same city.
