I think in retrospect it would have been better to offer 50% and the same salary as you.
Going forward though, I'd say definitely learn to hack. Also find people who might help not because of a salary, but because they think the idea is cool and want to be part of it.
Any scaling equity package should be linked to dates and performance goals. You basically said you didn't want her to own the company unless it succeeded, when success was contingent on her.
Sounds like she trusted you. Then stopped trusting you. Then left a few months later. You screwed up. Go apologize.
It wasn't a hazy equity offer.
Stop refuting everyone's opinion.
For example, if there was another partner here that knew how to hack, but wasn't a nurse, I'd say: Learn as much as possible about health care - it's your industry.
it does sound like she didn't have the experience or the maturity to whittle down to an achievable project, however. learn to code, maybe that plus this experience will make you a much stronger manager and designer next time around.
Point remains that asking for equity does not fit with expectation of failure.
It doesn't have to be that long. Do you have any programming experience? Do you have any friends that do? With a smart friend guiding you through, you can skip a lot of annoyances when you learn to program.
This is also a prudent point - what have you been doing the last 12 months? That would have been more than enough to get the hang of Django...
Market research, ethnographic study, trying to raise more funding,(too early for VCs here, and there are not many risk taking angels here), running the ongoing alpha, liaising with patient groups, and health organisations, writing copy and designing interfaces. Learning about tech startups is a phase transition from the perspective of a nurse.
The idea was that always that she would be a full co-founder. We agreed on a low equity split initially because of the asymmetric risk we were taking. The idea was always to increase her stake 6 months into the project, but not in the way it happened.
I met her through a friend, and 3 months ago would have been proud to call her my cofounder.
I am going to learn to hack regardless, I am just trying to figure out the best way forward in the short term, as the payoff for learning to hack will be a few months.
