Jan Sebastian Steffen — CEO
Co-Founder & CEO | re-entry.ai I’m building re-entry.ai - a governance and risk control layer for modern software development. As AI increasingly writes, reviews, and ships code, traditional processes no longer scale. re-entry.ai sits between code and production to help teams define, enforce, and audit how software changes are allowed to ship. My focus is on designing systems that translate human intent into deterministic, auditable controls - enabling teams to move fast without losing reliability, accountability, or trust. Previously, I led strategic, product, and technology initiatives across global OEMs and tech ventures — translating complex systems into scalable, human-centric solutions. My work now centers on bridging AI, focus, and performance in the modern workspace. Actively looking for angels, advisors and VCs. Interested ? Let's have a chat!
