As answered by people managing Tutanota and StackWeaver.cloud.
StackWeaver.cloud's answer:
Regulated fintechs, payment service providers and B2B SaaS companies in Nigeria and across Africa. In particular, CTOs, founders and compliance leads preparing for CBN examinations, NDPC audit returns, SOC 2 or ISO 27001 audits, bank security questionnaires or investor due diligence. The audit, compliance and advisory firms that serve those companies and want one place to run engagements with them.
StackWeaver.cloud's answer:
eact, TypeScript and Vite for the portal. Astro for the website. Cloudflare Pages and Workers for hosting and server functions. Supabase (PostgreSQL with row-level security, Vault and Storage) for data and evidence files. Clerk for sign-in. Paystack for payouts. SHA-256 hashing and an open JSON-based evidence package format.
StackWeaver.cloud's answer:
StackWeaver is built for African regulation first. CBN AML/CFT (including the Baseline Standards for Automated AML Solutions) and NDPA sit alongside SOC 2, ISO 27001 and PCI DSS, rather than being bolted on as an afterthought.
It also treats evidence as something that must be provable, not just stored. Every file gets a SHA-256 fingerprint and an evidence ID. Every review and sign-off is written to a chained decision record that shows if anything was changed later. Evidence can be exported as a package in an open, documented format that an auditor can check without a StackWeaver account.
Finally, it pairs the platform with hands-on compliance engineering, so the evidence is actually produced, not just tracked.
StackWeaver.cloud's answer:
Most compliance automation tools are designed around US frameworks and US cloud stacks. If you are a Nigerian or African fintech, you need CBN AML/CFT and NDPA covered properly, local pricing, and a team that understands local regulators and banks.
StackWeaver gives you that, plus:
a portal your audit or advisory firm can work in with you, reviewing and signing off evidence in the same place; an evidence package your auditor, bank or investor can verify on their own; engineers who help implement the controls, not just a dashboard that lists what is missing.
StackWeaver.cloud's answer:
Our founder, Oluwafemi Ofobutu, kept seeing the same pattern in regulated fintechs. Engineering stopped being the problem, product stopped being the problem, and trust became the problem. Investors asked for evidence, enterprise customers asked about security, and regulators asked for proof. Most companies answered by producing more documents, more spreadsheets and more manual work before every audit.
StackWeaver was started to go the other way: make trust something a company demonstrates continuously through the way its systems operate. It began as compliance engineering for African fintechs and grew into a platform where evidence is collected once, reviewed, signed off and shared in a form others can verify.
