Questions & Answers

As answered by people managing Project Euler and Knowally.

What makes your product unique?

Knowally's answer:

Most questionnaire tools are built for generic RFP responses. Knowally is purpose-built for security questionnaire automation — it uses your own uploaded security documentation (SOC 2 reports, ISO 27001 controls, internal policies) as the source of truth for every answer. Responses are grounded in your actual documents, not a generic knowledge base, making them accurate and audit-ready from day one.

Why should a person choose your product over its competitors?

Knowally's answer:

Knowally is significantly more affordable than Loopio or Responsive with no per-questionnaire fees. It's GDPR-compliant and EU-hosted — critical for European vendors. Setup takes minutes: upload your existing docs and start answering immediately, no onboarding call or training required. The Answer Library compounds over time — each questionnaire you complete makes the next one faster.

How would you describe the primary audience of your product?

Knowally's answer:

InfoSec managers, GRC analysts, and trust & compliance teams at B2B SaaS companies and software vendors that receive security questionnaires (CAIQ, SIG, SOC 2, DDQ, VSA) from enterprise customers or investors as part of their sales cycle. Typically 5–500 person companies without a dedicated RFP team.

What's the story behind your product?

Knowally's answer:

Knowally was built after experiencing firsthand how much time InfoSec and sales teams waste manually answering the same security questions for every new enterprise customer — copying from old spreadsheets, hunting through policy docs, starting from scratch each time. The goal: upload your security documentation once, let AI handle the repetitive drafting.

Which are the primary technologies used for building your product?

Knowally's answer:

Python (Flask) backend, Vue 3 frontend, PostgreSQL with pgvector for semantic search, Anthropic for AI answer generation. Hosted on Hetzner in the EU. GDPR-compliant architecture with all data processing confined to EU regions.
