Something you can try.
A batch is a set of related features or improvements that we build for you to review together. We agree on the scope around a useful outcome.
The size depends on the work. The point is to put progress in your hands so your feedback can shape the next round.
For example
Help new users finish signing up.
One batch could bring together a simpler signup flow, clearer form screens, the development behind them, and testing.
You try the working flow. We review your feedback together, make adjustments, and decide what to tackle next.
