Agentic AI
Agents that use real tools
Agents that call real tools, show their working, and stop when they are unsure.
Taking on new builds for Q4
Engineering AIthat reaches production.
Zesxai is an AI software studio. We take products from a blank page to production — SaaS platforms, autonomous agents, and the unglamorous migrations that make everything else possible.

Our stack
Boring tools, chosen on purpose.The interesting part is what we build with them.
Built AI-native.Not AI-flavoured.

Products we took to production
A few of the builds we can talk about publicly — migrations, AI platforms and automation systems that are live today.
Migration2025
Busyless
A seven-year-old Angular scheduling app rebuilt on Next.js — same features, a third of the load time, and a codebase the team can actually change.
LCP 4.8s → 1.1s

We build for ourselves too
Everything we learn shipping client work goes back into our own products — and vice versa.
OpusSiteScore
In developmentThe scoring layer for AI-era websites
OpusSiteScore audits a site the way a model reads it — structure, semantics, answerability — and returns a score plus the specific fixes that move it. Currently in private development.
- Crawl-and-score across performance, semantics and answerability
- Prioritised fix list with effort estimates
- Tracks score movement over time
- CI check so regressions never ship
Axzura
LiveAnswers from your own documents, with the receipts
Axzura turns decades of operational documents into queryable answers, and traces every one of them back to the passage it came from. Our own platform, live with eleven tenants.
- Every answer cited to a source passage
- Says "not in the corpus" instead of improvising
- Tenant isolation enforced at the database layer
- Sub-second answers at the 95th percentile
How we work
Three steps, no theatre
Small senior team, short feedback loops, and a bias toward putting something real in front of users early.
Scope
A week of hard questions. We pin down the one outcome that matters, cut everything that does not serve it, and hand you a fixed plan with a date on it.
Build
Weekly shipped increments in a real environment, not slide decks. You see working software every Friday and can redirect at any point.
Ship & hand over
We launch, instrument, and document. You get the repo, the infrastructure and a team that can run it — or we stay on to operate it.
