I think it's really helpful to start with lowish expectations. That just gives the team you hire a good platform to exceed expectations. Remember also that if you're making a choice between making an investment or making a grant, with a grant, that money is 100% gone, but if you make an investment through a DFI, the intention of course is that you get a positive return, and then it becomes a renewable balance sheet. Even if you make some losses, you're still making better returns than losing everything. I think accepting that you're taking risk, giving it time, and having your return expectations reasonably low gives yourself the best chance of being in a great place to build on that in 10 years' time.
