Example

What you give it

We're 3 founders building a scheduling app for dog walkers in Lima. 140 walkers use it; 60 signed up in the last 4 weeks, 31 of them invited by another walker. Weekly active walkers went 70, 82, 95, 104 over the last 4 weeks. We're also building a pet-owner app and talking to a vet chain about a partnership. Time: walker app 40%, owner app 35%, vet partnership 25%. We look at sign-ups once a month. Nobody owns fundraising.
