This is great, though one key practical challenge: in most cases only founders will really be "taxed" in a meaningful way, so it requires that founders want to and decide to do something that loses them some serious $$ (as noted in answer to the second FAQ).

While I believe the additional upside presented to employees will have a positive impact re: incentive alignment and motivation, it is TBD if the gains realized by the founders will exceed the cost to the founders - I think that will be required before massive adoption (probably the biggest challenge here is measurement of that impact).

Still, hopefully some just-plain-nice founders do this, and I hope it gets them a great team and great success.

Even without mass adoption, it would be awesome to see this get adopted by other companies who (like Detour) were started by already-exited founders who are on a second (or third/fourth/fifth) project - there are actually a lot of them, so hopefully enough are gracious enough to experiment with this AND achieve success so that there is a sound basis for adopting this more widely (of course the trade-off might not be in the progressive equity’s favor – and while I’m making caveats, serial entrepreneurs generally do better than the first time entrepreneur for a bunch of other reasons like experience/connections, so it will be hard to determine/quantify what portion of success can be attributed to progressive equity and not to other factors…still hope they give it a shot anyhow).
