In the UK a CIC (Community Interest Company) is an option, which can legally oblige the company to act in the interest of "the community they serve". I think in the USA a benefit corporation might be similar.

Alternatively if Komoot was a worker co-op a sell-out would only be possible with consent from the employees. Consumer co-ops (where users can vote too) are also an option but with more caveats.
