There are similar projects out there including Index Coop and Alongside. But most teams with on-chain offerings run into cost issues trying to maintain index token price with portfolio NAV. I'm building in the space as well and am happy to chat if you're curious.

Looking forward to building together. I’m pretty new to web3 and made the transition to work on an idea. My web2 background is in engineering across the stack and management. I’m open to meeting up if you’re in Tokyo, and I’ll be in NYC in a couple months as well.
