Verdict
Think of these as three different jobs, not three tiers of the same one. Want startup exposure inside a broader private-market menu, and the lowest entry at $50? Republic. Want the cleanest startup-native crowdfunding? Wefunder. Want the largest, marketplace-driven flow of startup deals? StartEngine. Upside potential isn't the differentiator here — workflow and deal mix are.
| Factor | Republic | Wefunder | StartEngine |
|---|---|---|---|
| Primary use case | Broad private-market access | Startup crowdfunding | Marketplace-style startup flow |
| Minimum | $50 | $100 | $100 |
| Liquidity | Very low | Very low | Very low |
| Retail accessibility | High | High | High |

Featured platform
Best fit for startup access and broad retail participation.
Broad-access private investing marketplace spanning startups and other private deals, with retail-friendly access but highly variable opportunity quality.
Republic can make sense when you want access to private-company and niche opportunities that are otherwise hard to reach from a retail account.
All three are speculative startup platforms. The useful comparison is not which one promises bigger upside, but which workflow, category breadth, and deal mix best fit your venture-style sleeve.
