What pafin (formerly Cryptact) does
pafin is a Tokyo-based FinTech startup founded in January 2018 that builds software for cryptocurrency taxation and Web3 financial management. The company operates two core products: Cryptact, a subscription-based cryptocurrency tax filing service that automatically calculates profit and loss across multiple exchanges, DeFi protocols, and NFT transactions for Japanese tax reporting; and defitact, a free, registration-free Web3 bookkeeping tool that visualizes on-chain activity across wallets, DeFi positions, and NFTs. pafin is registered as an investment advisory agent with the Kanto Finance Bureau (Registration No. 3326) and is a member of the Japan Investment Advisers Association.
The company monetizes through tiered subscription plans for Cryptact aimed at individual investors and tax professionals, and uses a freemium model for defitact that relies on potential premium upsell. Distribution is product-led and self-serve through the Cryptact and defitact websites, supplemented by integration partnerships (notably Gtax in Japan) and PR-driven earned media coverage. Capital is reported at 1.364 billion JPY (including capital reserves), and the company is venture-backed by a roster of Japanese financial and Web3 investors including JAFCO, DG Daiwa Ventures, Daiwa Securities Group, bitFlyer, Sony Innovation Fund, Coincheck, MZ Web3 Fund, SV FinTech, Money Forward, D4V, minkabu, FFG Ventures, and Venture Lab.
The strategic posture has shifted from a single-product tax tool to a Web3 infrastructure platform: pafin rebranded from Cryptact, expanded to Australian tax filing in July 2026, integrated with Gtax as an industry-standard profit/loss engine, launched AI collaboration features, and co-founded Iyogazolab with the University of Tokyo and SoftBank in September 2025 to support medical AI development through medical imaging data infrastructure.

pafin (formerly Cryptact) competitors and assessment
Company assessmentDirect peers
- TokenTax: TokenTax targets professional and high-volume crypto traders with full-service crypto tax filing. It overlaps with Cryptact's professional-tier offering for tax accountants handling complex client portfolios.
- Zerion: Zerion is a DeFi and NFT portfolio tracker with multi-wallet visibility. It is the most direct analogue to pafin's defitact product on the consumer-facing Web3 portfolio/DeFi visualizer side.
- Zapper: Zapper aggregates DeFi positions across wallets and protocols into a single dashboard. Like defitact, it focuses on transaction visualization and management across chains and DeFi protocols, making it a comparable Web3 bookkeeping tool.
- ZenLedger: ZenLedger provides crypto tax software and accounting integrations for both individuals and tax professionals. It is comparable to Cryptact on the B2B tax-professional channel that pafin explicitly targets.
- CoinLedger: CoinLedger (formerly CryptoTrader.Tax) is a US-focused crypto tax software platform with similar multi-exchange ingestion and PLG onboarding. It is directly comparable to Cryptact on feature set and target customer.
- Koinly: Koinly is a leading global crypto tax calculation and portfolio tracking platform supporting hundreds of exchanges and wallets. It is the most direct international competitor to pafin's Cryptact product across the same PLG, multi-exchange, multi-chain tax workflow.
- Blockpit: Blockpit (which acquired Accointing) provides crypto tax and portfolio tracking across Europe and is expanding globally. It is a direct peer in the crypto tax-reporting category and serves as a benchmark for how a regional player can internationalize the product.
- CoinTracker: CoinTracker offers cryptocurrency tax reporting, portfolio tracking and TurboTax integration. It competes head-to-head with Cryptact on the consumer/professional crypto-tax workflow globally and represents the benchmark for product-led growth in this category.
- Gtax: Gtax is pafin's Japanese crypto tax integration partner, but it also operates a directly overlapping cryptocurrency profit/loss calculation product. The two companies are simultaneously collaborators (Cryptact↔Gtax integration) and competitors in the Japanese crypto-tax market.
Broad incumbents
- Money Forward: Money Forward is a major Japanese household-finance SaaS platform and a pafin investor. It offers broader personal-finance and accounting tools that increasingly include crypto, making it both a strategic investor and a broad incumbent whose product roadmap overlaps Cryptact's compliance/accounting core.
