Case studies

What we built, and what it changed.

Three AI systems we took from a problem statement to something running in production. What the problem was, how each one is architected, which parts were genuinely hard, and what we would do differently next time.

Fintech
Invoice & statement extraction
Reads invoices, bank statements and utility bills at 97% field-level accuracy, and knows which fields it is unsure about.
Thousands of invoices were being keyed in by hand. Reconciliation waited on the typing, and reporting waited on reconciliation. The team had tried an off-the-shelf extraction API and abandoned it: it worked on the clean exports and failed on everything else, with no signal to say which was which.

Retail operations
Netra3 store monitoring
Turns the CCTV a store already has into live incident alerts and a daily footfall report.
Nobody can watch a wall of CCTV feeds all day. Incidents were surfacing the next morning in the recording, when they surfaced at all, and head office had no view of what normal looked like across locations.
- Computer vision
- Video analytics
- Real-time alerts
- Dashboards
40%Faster response to operational issues
91%Of alerts marked worth knowing about

EdTech
AI-first student management portal
A portal where custom models mark the work and draft the feedback, and a teacher signs it off.
Teachers were losing their evenings to marking, and feedback reached students long after they had moved on. An earlier attempt at automated grading had been switched off after a fortnight because it marked written answers with the same logic it used for arithmetic.
- Custom models
- React
- Node.js
- Analytics
68%Less time spent marking
94%Of proposed marks accepted unchanged
