What questr.io does

questr GmbH (questr.io) is a specialist crypto data and compliance services firm headquartered in Graz, Austria. The company provides professional services for individuals, businesses, and financial institutions that require structured documentation of cryptocurrency transaction histories, proof-of-funds statements for banks and exchanges, and forensic blockchain analysis for AML risk assessment. Its core offerings include Krypto-Accounting (accounting and financial statements for crypto assets), Mittelherkunftsnachweis (proof-of-funds documentation), and Forensische Blockchain-Analyse (forensic blockchain analysis), supported by modular consulting products such as standardized video consultations on crypto tax tools (CoinTracking and Blockpit) and a dedicated Crypto Exposure Report (CER) for bank compliance departments.

The technology stack relies on industry-standard crypto tax software platforms (CoinTracking, Blockpit) combined with proprietary methodologies layered on internationally recognized blockchain forensics software for transaction tracing and money laundering risk assessment. The platform includes specialized workflows such as reconstruction of lost blockchain transaction histories and individualized proof-of-funds reports that combine customer data, portfolio software analysis, and blockchain forensics.

The business model is professional services based, with hybrid pricing — fixed-rate consultations (€132 for 30 minutes, €264 for 60 minutes) provide a self-serve entry point, while custom data preparation and forensic projects are priced hourly or per-engagement based on scope. The go-to-market combines direct website-driven sales, a bidirectional partnership with Enzinger Steuerberatung (a specialist Austrian crypto tax advisory firm from which questr was spun off) operating the joint cryptotax.at platform, and direct enterprise sales to banks and financial institutions for CER engagements. Customer segments span individual crypto investors, businesses with crypto holdings, banks and financial institutions, and tax advisory firms seeking crypto expertise. The company is privately held with no disclosed funding or institutional investors.

Scale indicators2 records

Recent moves7 records

Expansion highlights6 records

Emerging players

• Lukka: Crypto data, NAV, and tax-reporting services for funds, enterprises, and accounting firms. Comparable in serving institutions that need audit-ready crypto data, though Lukka is more software-focused and US-centric versus Questr's service-led Austrian model.
• Coinfirm: Blockchain analytics and AML/compliance firm with a strong European footprint. Overlaps with Questr's forensics, address-screening, and bank-compliance work, though Coinfirm operates with a more productized platform offering.
• 21Analytics: Swiss-headquartered blockchain analytics and compliance provider serving financial institutions in the DACH region. Closely comparable to Questr's CER offering — same geography, same bank-compliance buyer, more software-led delivery model.

Direct peers

• CryptoTaxCalculator: Automated crypto tax calculation software with strong presence in Europe. Competes with Questr for the same individual-investor and tax-advisor segment but via a self-serve SaaS product rather than bespoke data-preparation services.
• Blockpit: Austria-based crypto tax and portfolio tracking software used heavily in the DACH region. Blockpit is a direct competitor to Questr's data-preparation and tax-reporting services, especially for self-serve users, and operates in the same regulatory environment with overlap in target customers.
• CoinTracking: Long-standing crypto tax and portfolio tracking platform widely used by Questr's clients. It competes directly for the same individual-investor and tax-advisor workflows that Questr services with its data preparation and tax-tool consulting offerings.

Broad incumbents

• KPMG / PwC Crypto Tax Practices: Big-Four advisory practices with dedicated crypto tax and accounting teams serving enterprise clients. Compete with Questr for corporate crypto-accounting and audit-support engagements, particularly with mid-market and larger Austrian/German companies.
• Chainalysis: Global leader in blockchain analytics and AML compliance for crypto, serving banks, governments, and exchanges. Comparable to Questr's CER/forensics work but at vastly larger scale and with proprietary software — Questr effectively uses comparable analytical methodologies for a regional niche.
• Elliptic: Blockchain analytics and crypto compliance platform offering transaction monitoring, forensics, and AML screening for financial institutions. Conceptually similar to Questr's bank-facing CER product, though Elliptic operates as a global SaaS incumbent rather than a regional consultancy.

Regional players

• Bitcoin Suisse: Swiss crypto financial services provider covering brokerage, custody, staking, and tax/regulatory support. Comparable in the DACH-region crypto-services ecosystem and in needing/handling proof-of-funds documentation, though operating primarily in Switzerland rather than Austria.
