Audit tools Companies in Europe

Evervault is a European cryptography company that lets developers encrypt sensitive data in transit and at rest without rearchitecting their systems. Rather than forcing teams to build custom encryption pipelines or rely on legacy HSM infrastructure, Evervault provides APIs and SDKs that integrate directly into applications—turning what was once a compliance headache into a developer experience problem. The company operates at the infrastructure layer, sitting between your database and your users. It handles encryption orchestration, tokenization, and secure computation without requiring you to manage keys or understand the underlying cryptography. This means your data stays encrypted in your own cloud account, your keys stay with you, and third-party vendors never see plaintext information. In a European market where data residency and privacy regulations have teeth, Evervault solves a real problem: companies need to protect customer data but can't afford to rebuild their entire tech stack. The platform works with existing databases, APIs, and infrastructure, making compliance less of an engineering ordeal. Evervault positions itself as the encryption layer for modern applications—not a database replacement, not a VPN, but the plumbing that makes data protection feel native to your code. It's particularly relevant for fintech companies handling payment cards, personal identifiers, and healthcare records across distributed systems. The company is helping reshape how European companies think about security: not as an afterthought, but as architecture.

Pliant is a compliance automation platform built for financial services firms that are tired of drowning in spreadsheets and manual processes. Rather than layering another point solution onto an already fragmented tech stack, Pliant unifies risk, compliance, and audit workflows into a single operating system. The platform handles the tedious work—continuous monitoring, policy enforcement, evidence collection, regulatory reporting—that currently consumes entire compliance teams and slows down growth.

Crypto turned millions of Europeans into accidental tax risks. Every trade, swap, staking reward, and NFT sale is potentially a taxable event, scattered across exchanges, wallets, and chains that were never designed to produce anything a tax office would accept — and for years the gap between what the law required and what anyone could practically compute was where most crypto investors quietly lived. Blockpit was founded in Linz in 2017, by CEO Florian Wimmer and his co-founders, on the bet that this gap would close and that someone European should build the software for it. The compliance-first DNA was there from the start: a cooperation with KPMG to validate the tax logic, and TÜV Austria certification of the calculation engine in 2020 — credentials aimed at tax advisors and auditors, not just crypto Twitter. The product is a portfolio tracker that ends in a tax report a local authority will actually accept. Users connect exchanges, wallets, and blockchains; Blockpit reconstructs the transaction history, classifies every event, and generates ready-to-file, country-specific reports across more than 100 jurisdictions. The differentiation is legal precision rather than chart polish: Germany's one-year holding-period exemption, Austria's 27.5% capital-income regime, France's specific rules — encoded per country, where the big US-born competitors historically produced generic exports and left the local law to the user. That focus made Blockpit the reference tool in the German-speaking world, voted best crypto tax calculator by the BTC-Echo community three years running from 2023 to 2025. It also consolidated the European field with unusual decisiveness for a company its size. In 2020 Blockpit merged with CryptoTax, its German rival. In November 2023 it acquired Accointing — the Swiss competitor that Glassnode had bought only a year earlier — in an all-cash, multi-million deal financed through shareholder debt, shutting the Accointing platform within months and migrating its users. Wimmer was explicit about the reasoning: the deal was preparation for DAC8, the EU directive that changes what this entire category is for. Since 1 January 2026, crypto-asset service providers across the EU must report their customers' transaction data to tax authorities under DAC8 and the OECD's CARF framework. The era in which crypto taxes were a voluntary-compliance problem is over — tax offices now receive the data automatically, and the reconciliation burden lands on the individual. Blockpit spent five years positioning to be the consumer side of that equation. The company profile behind this is strikingly lean: roughly 30 employees, profitability reached in 2024, and a $10 million Series A from 2021 led by MiddleGame Ventures — until March 2025, when Raiffeisen Bank International invested millions through its venture arm Elevator Ventures, the fund's first crypto investment. A major Austrian banking group buying into crypto tax compliance is itself a market signal: the institutional world expects enforced crypto transparency to be permanent infrastructure, not a cycle product. Blockpit has since been publicly flagged among Austrian startups exploring an eventual IPO. It sits within an Austrian crypto cluster that punches far above the country's size, alongside Bitpanda's licensed brokerage a train ride away in Vienna. The honest read cuts both ways. The risks are real: demand breathes with the crypto cycle, exchanges could bundle good-enough tax reporting natively, and global competitors like Koinly fight for the same users. But the structural driver is a ratchet — regulation like DAC8 does not un-happen, every new reporting regime adds jurisdictions to the addressable market, and the moat in this category is the unglamorous one of encoding a hundred countries' tax law correctly and keeping it current. A profitable, thirty-person company that owns the DACH market, absorbed its two nearest rivals, and has a systemically important bank on its cap table is about as well-positioned for enforced transparency as a startup can be. Blockpit's founding bet was that crypto would eventually have to grow up and file its taxes. As of January 2026, that's no longer a bet.

Antoine Scalia founded Cryptio in Paris straight out of business school around 2018, on a bet that looked premature for most of its life: that large institutions would eventually hold digital assets and would then discover their accounting systems couldn't cope. A bank transfer leaves a line on a statement; a blockchain transaction is scattered across wallets, custodians, exchanges and protocols, in a form no ERP was designed to reconcile. Cryptio transforms that data — DeFi, custody, OTC, exchange — into auditable records for accounting, treasury and tax filing. The bet paid off in 2025–2026. FASB rules requiring fair-value reporting of crypto assets took effect in 2025, the SEC replaced SAB 121 with SAB 122 easing bank custody, and institutional adoption accelerated — turning a niche product into infrastructure. Cryptio now has over 400 clients across more than 30 countries, including Circle, Gemini, SG Forge (Société Générale's blockchain arm), Securitize and Nomura's digital assets subsidiary, and all four of Deloitte, EY, KPMG and PwC rely on its data in audit procedures. Over $3 trillion in transaction volume has passed through the platform. In March 2026 Cryptio raised a $45 million Series B led by BlackFin Capital Partners and Sentinel Global, with 1kx, BlueYard and Ledger Cathay Capital participating — a substantial round for a company that had raised around $26 million previously, and one closed on institutional traction rather than crypto-cycle enthusiasm. Cryptio completes a natural cluster in your database with Blockpit and Koinly: all three turn blockchain data into tax and accounting output, but Blockpit and Koinly serve individuals while Cryptio serves the institutions and their auditors — the same problem at opposite ends of the market.
