About
Built by the practitioner who did the work.
Matterlyt answers the security and AI-governance questionnaires that stand between companies in the AI stack and their enterprise deals. Every answer is cited, confidence-flagged, and ready for you to put your name on — grounded in the questions enterprise buyers actually ask, and answers built to survive their scrutiny.
Why it exists
You know the moment.
Your first real enterprise deal is all but signed. The buyer loves the product, the terms are agreed — and then the email lands: “Before we can proceed, please complete our security review.” Two hundred questions, due next week. Increasingly there’s an AI annex stapled to it that nobody warned you about: model provenance, training-data rights, which LLM sub-processors touch customer data, prompt and output retention.
At an AI company, that sheet doesn’t land on a compliance department — there isn’t one. It lands on you, the founder or CTO, on top of shipping the product. The deal you won on merit now waits on a spreadsheet, and every week it sits unanswered is a week it can quietly go cold.
Matterlyt exists for that moment. It answers the security and AI-governance questionnaires that stand between companies in the AI stack and their enterprise deals — so proving you’re safe to buy from stops being the thing that stalls the deal.
Who builds this
Sebastian Galonska · Founder and CEO
Matterlyt encodes work Sebastian has done, not theory. He has spent his career on both sides of due diligence — building and running a fintech as founder and CTO, coaching other CTOs, assessing tech companies as a due-diligence expert for investors, and serving as the fractional compliance officer who carried an open-source AI-infrastructure company through the audits and questionnaires this product now answers. He knows the questions because he has asked them — and answered them.
- Fintech founder and CTO at Kontist.
- CTO coach at CTO Berlin.
- Due Diligence Expert at Philipps & Byrne — assessing tech companies for investors.
- Fractional Compliance Officer at Qdrant — the open-source vector database.
- Led three consecutive SOC 2 Type II audit cycles to completed reports — the last two including HIPAA.
- Established Qdrant’s EU AI Act applicability position.
Three consecutive Type II cycles is the part that matters: it is proof of sustained operation, not a one-time certificate. That is exactly what Matterlyt does for the answers you give buyers — keeps them true as your product, your sub-processors, and your posture change. The questions enterprise buyers ask, and answers that hold up under scrutiny, are what the product ships with.
