anchoring the exit valuation at $1B means any valuation that's already greater than that at time of grant (if user chooses that option) produces a zero outcome for equity value.

You should consider making outcome valuation a flexible number, or capping the current valuation at < $1B.

This also lacks a concept of future funding rounds that inevitably produce dilution.

Thanks for the feedback!

Yep I did realize the $1B issue too. Am building a way to dynamically set the exit valuation, probably next weekend.

As for dilution there isn't really a good way to factor that in. I still believe that using the BSM options model is a much better gauge of value than what most people use so hopefully it provides some benefits there.

yeah - the whole point here is that many people aren't sophisticated enough about how this stuff works to accurately predict future dilution (or to be aware of how various kinds of preferences work).

you could do something crude like extrapolating a data point such as size of last financing or TTD financing to estimate future dilution.

Good point actually, will try to create some kind of visualization for dilution.
