Gitcoin

Gitcoin is a platform that empowers digitally native communities to fund, build, and protect public goods, primarily through its Gitcoin Grants Program. It facilitates crowdfunding and grants for early-stage projects, fostering a decentralized approach to capital allocation and community engagement within the Ethereum ecosystem.

Gitcoin is a platform focused on decentralized public goods funding, which aligns well with the concept of a 'decentralized rogue think tank and R&D platform' that unites contributors and backers. While it doesn't explicitly state 'bleeding-edge project incubator' or 'rapid prototype development' in the same way, its core function of funding early-stage projects and fostering a community of builders implies these activities. The platform's emphasis on community-driven funding, open contributor networks, and transparent governance strongly matches the must-have features. The 'Grants Program Canvas' and 'Onchain Capital Allocation Handbook' also suggest a structured approach to managing projects and resources, aligning with a 'modular project portfolio' even if not explicitly named as such.
