What Unnax does
Powens (formerly Unnax) is an Open Finance Platform providing financial data aggregation and payment initiation services through a single API to banks, fintechs, lenders, and ERP/accounting software providers. The platform connects to 1,800+ banks across Europe and covers three core product categories: Financial Data Aggregation (Transactions, Business Transactions, Wealth & Loans, Business Wealth & Loans), Accounts & Payments (Virtual IBANs, Instant SEPA Transfers, Direct Debit, Pay by Bank), and Identity & Fraud Verification (Bank ID Check, Valitic). In 2025 the platform processed 6.3M payments totaling €2.7B and reported 5M monthly aggregated accounts, with Pay by Bank transactions up 297% year-over-year.
The underlying business model combines subscription/usage-based API access with transaction-based payment processing fees, monetized across 300+ enterprise clients in banking, fintech, lending, accounting/ERP, wealth management, property management, and cashback/rewards. Distribution is API-first, combining a self-serve sandbox (Powens Console) for developer-led adoption with direct sales for enterprise contracts, supplemented by dedicated Startup and Partner programs. The company operates multi-market through Powens SAS (France, ACPR-licensed payment institution), Unnax Regulatory Services EDE, S.L.U. (Spain, Bank of Spain-licensed electronic money institution), and Unnax Payment Systems S.L.U. (Mexico, reseller and data solutions), with 120+ employees across the three geographies.
Powens has been profitable and self-funded since its last disclosed funding round in January 2021 (~$8.6M), and the 2026 rebrand from Unnax to Powens consolidates the combined data-and-payments positioning under a single brand. ISO 27001 certification, local regulatory authorizations, and named enterprise customers (BNP Paribas, Natixis, Wolters Kluwer, Qonto, Younited) underpin the company's positioning as a regulated infrastructure provider rather than a point solution.

Unnax competitors and assessment
Company assessmentDirect peers
- Plaid: The dominant global open banking aggregator with bank connectivity and payment initiation capabilities. Most directly comparable in product (data aggregation + payment initiation via API) and target customer (fintechs and financial institutions), though materially larger and better capitalised.
- Tink: European open banking platform owned by Visa, offering account aggregation, payment initiation, and identity verification across 20+ European markets. Directly competitive in Powens' core geography and now backed by Visa's distribution and balance sheet.
- TrueLayer: UK- and Europe-focused open banking API provider with similar aggregation + payment initiation + KYC product surface. Competes head-to-head with Powens for fintech and lender accounts in the UK and Western Europe.
- Yapily: European open banking infrastructure provider connecting to thousands of banks via a single API for data and payments. Closely comparable product offering and customer base to Powens, with broader pan-European coverage.
- Salt Edge: Open banking and account aggregation API provider serving banks, fintechs, and lenders across Europe and beyond. Highly comparable in product scope (data aggregation + PSD2 AIS/PIS + KYC).
- Token.io: Open banking payments specialist focused on account-to-account payments, variable recurring payments, and pay-by-bank. Comparable to Powens on the payment initiation side and competes in the same pay-by-bank growth category.
- Belvo: LATAM-focused open banking and account aggregation API provider. Most directly comparable to Powens' Mexico operations and is the leading player Powens must displace or partner with in the Mexican market.
- MX Technologies: US-focused financial data platform offering aggregation, payment initiation, and financial wellness tools. Comparable product architecture though geographically separate; useful benchmark for North American expansion thesis.
Broad incumbents
- Trustly: Established European open banking-based account-to-account payment network owned by Nordic Capital. Overlaps with Powens' pay-by-bank product but operates at much greater scale and is more merchant-focused than API-focused.
- Finicity (Mastercard): Open banking aggregator acquired by Mastercard, providing bank connectivity, verification, and payments APIs. Comparable on data aggregation and KYC; distribution advantage from Mastercard and broader international footprint than Powens.
