It is a little hard to tell how the per customer and lump sum compare without knowing how many customers they have. Your lump sum represents 18,000 customer months. Equity is always a gamble but I think you should take your own words to heart. "I made the decision to build software exclusively for Teaching Company because I believe in their product" If you believe in this company then the equity might be more important to you (sense of accomplishment) than the money. It would be to me. The other thing this highlights is that people should really get this contractual stuff out of the way before hand if possible. It would be a shame for either party to feel slighted as a result of this opportunity. If it were me, and I truly believed in the company and their mission particularly given I might have worked on the app in my spare time and that I don't need the cash, I would counter with a proposal for actually less pay (potentially none) upfront but more equity. But that is me and factors in my financial situation. I would love to own 10% of an education related company that I actually believed in.
