I have an idea, a co-founder, a company bootstrapped and running. I have potential customers who like the idea and are ready for a beta. And I am pursuing the idea whether or not the angel money comes through (just a whole lot more slowly).
Oh, I was expecting a more general discussion about business plans so I didn't put in too many details. I have talked to quite a few customers during our customer dev and some of them really like the idea. They think this innovation will increase their revenue but no one is sure by how much (and there is of course the risk that we are all wrong about it or the idea needs pivoting before it does that). It also involves a little bit of hardware so I need about the amount of money an average yc company gets from yc to get to the demo from here. I can do some other somewhat related projects to slowly raise that money but that is just wasting time. Ideally I should just get on it and get the demo out and deployed. Once we see what effect if at all it has on our customer's sales and how much it cost us to get that, we can iterate, price, figure out the revenue and generally write a business plan we could honour.
So, basically my angel's roi is not clear and a convertible note with a reasonable discount sounds ideal but the system here is the system and I don't want to waste time fighting it. I will put in a business plan to get talking to the right guys and then try and convince the right angel to ignore it and do a convertible note and hopefully all will be well in the world again. This will have the unfortunate side effect of polluting my mind with fake figures and expectations which I wish I could avoid but that's just part of the game at the moment.
To be honest, I am not at the top of my game in that sense and no one should expect me to be at this stage. Enough data doesn't exist to make good guesses now. Generating it is exactly why I am approaching an angel and trying to get to demo and beta.
