I am curious about one aspect though: Debugging spreadsheets is seriously hard. How do you help customers verify their spreadsheet has the right things they are looking for, avoiding regressions due to a random change by some inexperienced person, etc.?
Also, at what point do you see companies move from spreadsheets to simply hiring developers to do what they want? It seems like beyond a point, spreadsheets can get in the way, and the company has enough resources to hire a team to build custom internal tools.
Good luck with Coefficient!
