Why did you choose to charge with a percentage model instead of a flat fee? If I'm a "hero" and offset double my footprint why should I be charged double for doing that? Is the cost to you as a business relative to the dollar amount I donate?
We originally chose a percent fee because it was an industry standard model that many in the carbon offset space expect. However, we're learning that industry standard here does not mean it's the best possible option.
The big reason why a % fee is good is because for small donations (e.g. 25% of someone's footprint) it makes more sense to scale it. A $4 transaction cost on a $2 impact to the project is crazy.
The tricky thing about our cost structure is that currently we do not have enough revenue to cover our overhead expenses, so even if we're ignoring the per transaction cost we need to find a way to cover our overhead (e.g. a place for us to live so we can hack on this all day)
They could either receive those as Stripe payouts, or further reinvest their earnings into curing global warming
i.e. cure global warming MLM style
This could also open up some nice customer acquisition strategies benefit from asymmetric motivation: teenagers/kids bunch of teenagers (who would spend hours persuading their rich parents /grandparents to donate $50/mo, such that in return the teenager earns $5/mo). This may be able to help mitigate the problem that older people are less likely to believe in the severity of global warming than younger people - in the same way that your grandma bought your magazine in 5th grade (so that you could win a prize, not because she actually cared about the magazine) as part of those gamified magazine fundraisers in elementary school
