About Tweezr

Critical systems were running on faith. So we built Tweezr.

Organizations running legacy estates have lost the knowledge of what their core systems actually do. Tweezr gives it back, so teams can evolve them without fear.

Where it started

We come from opposite sides of the same problem: running core banking inside a tier-1 bank, and building AI systems in deep tech. We kept seeing the same failure. Brilliant teams frozen because no one fully understands the legacy estate, while AI copilots confidently hallucinate logic that breaks production.

  1. How we formed

    The people who built these systems are retiring, and the documentation can't be trusted. So we assembled a team that has shipped inside tier-1 banks, mainframe shops and AI-native products. That combination is rare on purpose.

  2. Why we built it

    You can't safely evolve a system you don't understand. So we recover it first: a complete, cited model of the code, every dependency, every rule. Then AI acts on a foundation it can trust. Tweezr isn't another copilot. It's the system-intelligence layer underneath that makes copilots, migrations and audits safe.

  3. What we're building

    A platform that turns the black box into a blueprint your team can trust. Understand the system, control every change, and evolve it with evidence that holds up when regulators ask. Built for the CIOs, Heads of Core and Chief Architects who have to modernize without breaking what already works.

“We saw the same story at every major bank: brilliant teams paralyzed by the fear of the unknown. We provide the light that turns that fear into a roadmap.”
