You might be interested in TinySeed's Syndicate offering — we started this for companies who are beyond the needs of the accelerator but would benefit from raising money (for instance, to deploy on new initiatives, or to take money off the table as a founder, or to buy another business, etc.): https://tinyseed.com/syndicate-founders
Tracy here from TinySeed, thanks for linking to our thesis!
Point of clarification: we don't do profit-sharing. Instead, we are equity owners. So when a company gets to the point of success where they want to take money off the table, they can issue dividends (and TinySeed get's a pro-rata amount of those dividends). I find this is one of our most unique points and aligns the incentives of the founder with TinySeed.
As mentioned in that page, by investing broadly into B2B SaaS, we can succeed as a venture firm without needing to count on unicorn exits. We're about to back our 80th company, and our founders tend to be older, more likely to have families, and tend to be "unsexy" businesses. We're only a few years old, but we've had very promising results (as a VC firm) so far.
