Owns the core loop. Turns fuzzy pitches into tight, testable mechanics.

What partners say

Jisenavo took our napkin pitch to a Switch launch in eleven months. The prototype sprint saved us from building the wrong game entirely.
DDaniel R.Publisher, Manchester · March 2025
Their low-poly kit shaved our environment budget in half and still hit 60fps on handheld. The optimisation pass paid for itself.
AAmara O.Indie developer, Bristol · January 2025
We embedded two of their engineers for a season of live ops. Retention climbed 22% and our own team learned a ton in the process.
