What we set out to build

Three claims, traced to the files behind them.

The problem

Adults with moderate to severe haemophilia must assess and manage unfamiliar bleeds, any time.Problem statement files

The bet

Bleedwise: the bleed record, signed by your centre. Carried from setup to recovery, shared with your care team if you choose. Never diagnoses or calculates a dose.Solution files

The partner

The Haemophilia Society of Singapore has about 280 patients and zero paid staff.WFH files

The files
