Thumba has significantly improved the way we translate high-level requirements into clear, actionable user stories, acceptance criteria, and test cases. What's been especially valuable is the ability to identify gaps early - before development even begins - which has kept our projects on track. We were at risk of missing key milestones, for one of our largest initiatives, due to timing and resource constraints.

However, in less than 1 hour, using Thumba, 30+ user stories were scanned for gaps and generated over 50 detailed test cases - along with preconditions, test steps, test data, and expected results for each. That acceleration not only saved 40 hours on a single project but allowed us to move forward with greater confidence and maintain delivery momentum.

Thumba vs Gen AI tools

A purpose-built engine — not a clever prompt.

Generic models are great at writing poems. They are not great at running an enterprise backlog.
