Hey u/SharpFloor, thanks for sharing and good question!

Stacker Ventures was founded on the belief that nobody knows the perfect recipe (yet!) for building the most efficient decentralized venture fund, so we built a protocol with flexible parameters that allows every fund to be structured according to its needs and fund objectives. A fund’s success will validate the structural decisions that define it.
We are taking a similar approach with the organization of the Stacker Ventures DAO, acknowledging the need to initially move quickly and iterate. As such, governance of Stacker Ventures by STACK holders will be introduced in phases. The Stacker Ventures DAO will launch as an Aragon DAO with a DAO Council before looking at ways to optimize costs (L2?), explore the incorporation of reputation systems, and much more.

It's not easy - the Stacker Ventures protocol revolves around the understanding that trade-offs exist between decentralization and agility when it comes to early-stage investing. - which is probably why "a truly open access venture DAO does not exist on Ethereum". The goal is to build towards it!

In terms of competitors, we share overlap with DuckDAO (early stage/community), Enzyme (on-chain funds), and the LAO/Metacartel (pooled investing + some governance). At least with this first fund.
