Investor B communicated their intention, do you/they have a copy of this? The intent might matter other than the letter of the agreement.

“I am going to get paid $0 today. When you raise your round, if you raise $X1, I am going to be paid $Y1, if you raise $X2, I am going to be paid $Y2, and so on…”

You’re welcome.

Think app development as if it is farming.

Your outsourcing company is basically just a farmhand. You ideally still want your own technical people, if anything to act as the architect. This is because many of the architecture choices’ will impact your outcome, but not in an immediate way. Sure, the outsourcing company can help you architect, but their goal is to complete the dev and handover, not the potential future problem if certain things are done in a certain way.

For example, because their goal is to show that they have planted some crops, and that the crops is producing during handover, they can just choose to hand water all the crops (easiest) and not build a proper irrigation system.

Now to answer your question, the farm can run today, but things do break down. Suppose there is no rain for an extended amount of time, you will need to quickly adapt on how to sustain your farm. If you don’t have anyone inhouse, it will be very risky.

You will also need to make sure your soil is healthy along the way.

Point is, tech development is a “living” thing. You can’t just do it once and be done with it.

Few ways to be successful/make money:

1. Be lucky
2. Work hard and be lucky
3. Work smart and be lucky

I.e. always account for the fact that there is randomness, and if you fail, don’t get all discouraged and try again.
