This is pretty cool. Overall I like the product and it is easy to use. I have some feedback too.
For the runway calculation, it would be great if I could add an estimate for upcoming expenses to see how that changes the calculation. For example, I am getting ready to hire a contractor and would like to have some sense of what the runway is after hiring the contractor. I could of course change my current bank balance, but I would prefer to have another field for upcoming expenses.
I really like the cost per user to serve, but I would like it to go further: cost per user based on all operating costs, cost per user for free users, cost per user for paid users. The idea being I can get a better sense of whether the pricing structure is correct. Are free users costing too much? Is the margin with paid users enough to cover the costs of free users? etc
Lastly, some way to automate data input would be great. Even a simple API would be a good start and then integration with services which have this sort of information would be even better.
