This is pretty cool. Overall I like the product and it is easy to use. I have some feedback too.<p>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.<p>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<p>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.
