EU fintech software fails compliance reviews for predictable reasons: payment states that drift out of sync with accounting records, data processed outside the jurisdiction it should stay in, and AI tools that quietly export sensitive records to a non-EU vendor's cloud. Knovik treats those as architecture decisions made up front. The pattern is already proven in shipped work: signature-verified payment webhooks with automatic accounting sync (built with PayHere and Zoho Books for Cowork.lk — the same signature-verification discipline PSD2's Strong Customer Authentication expects), database-level row security, and Letalk, our edge LLM product built precisely so finance teams can analyze data in natural language without a record leaving their environment.
Payment flows where a transaction is only marked paid after a signature-verified webhook confirms it — the same verify-before-trust discipline PSD2's Strong Customer Authentication requires — with invoices created automatically in your accounting system.
Natural-language analysis of transaction data and customer portfolios running on infrastructure you control — the edge LLM approach behind Letalk — for data that can't be sent to a cloud AI provider under GDPR or your own risk policy.
Web platforms with row-level security enforced in the database rather than trusted to application code, data residency decided at architecture time, and audit trails that shorten a compliance review instead of lengthening it.

Full profile on knovik.comYes. An edge LLM runs on hardware you control, so transaction data is analyzed in natural language without any record being transmitted to a third-party model provider outside the EU. That's the architecture behind Letalk.
The underlying discipline is the same: nothing is marked paid until a payment provider's signature is independently verified server-side, which is the pattern we shipped for Cowork.lk with PayHere. The same verify-before-trust approach applies to EU payment integrations under PSD2's SCA rules.
