Looks interesting! I think you might have some interest in MichaelA's shortform about impact certificates. I saw you mentioned some orgs that are in this space. You may also want to check out Dr. Aidan Hollis' paper, An Efficient Reward System for Pharmaceutical Innovation, and his organization which tries to pay for success, the Health Impact Fund.
The Health Impact Fund (cited above by MichaelA) is an implementation of a broader idea outlined by Dr. Aidan Hollis here: An Efficient Reward System for Pharmaceutical Innovation. Hollis' paper, as I understand it, proposes reforming the patent system such that innovations would be rewarded by government payouts (based on impact metrics, e.g. QALYs) rather than monopoly profit/rent. The Health Impact Fund, an NGO, is meant to work alongside patents (for now) and is intended to prove that the broader concept outlined in the paper can work. A friend and I are working on further broadening this proposal outlined by Dr. Hollis. Essentially, I believe this type of innovation incentive could be applied to other areas with easily measurable impact (e.g. energy, clean protein and agricultural innovations via a "carbon emissions saved" metric). We'd love to collaborate with anyone else interested (feel free to message me).
