FAQ
❓ Is 43North only for US companies?
Nope! International startups are welcome (and have won), but you need to be able/willing to incorporate and relocate to Buffalo.
❓ Can solo founders apply?
You can, but success odds drop. Teams of two or more are preferred—ideally CTO + CEO split.
❓ What stage are most selected startups?
Post-MVP and at least some early traction—the “I built my prototype last week” phase is too early. Pre-Series A sweet spot.
❓ Do all winners give up 5%—even at $1M?
Yes: flat 5% equity for all prizes. That’s very founder-friendly for these check sizes.
❓ What’s the catch on relocation?
Gotta move HQ or significant ops to Buffalo (not just a P.O. box) with an on-the-ground founder/lead for 12 months. No workarounds.
❓ Does 43North accelerator help with visas?
Limited; they’ll introduce you to Buffalo-based law firms but can’t guarantee results. Immigration is on you.
❓ Is remote participation ever allowed?
No—this is true in-person, ecosystem-embedded acceleration.
❓ Consulting, nonprofit, or service companies eligible?
No. Only scalable, venture-backable, product-driven businesses.
❓ What happens after 1 year?
You’re not contractually bound to Buffalo but many stay for ecosystem, support, and growth benefits.
Final Thoughts on
Here’s the play: 43North accelerator offers one of the best risk/reward deals in US acceleration—capital big enough to make a difference, equity light enough to bring investors in, and hands-on programming that’s way deeper than a basic “business competition.” If you can embrace a real Buffalo commitment, there’s powerful value here: community, PR, access, and proof your team can play big outside legacy startup ZIP codes.
If you’re a mission-driven, high-growth founder open to new geographies and want a launchpad that’s proven (not just hyped), 43North absolutely rates a closer look. The selection bar is high, but for those who prep, commit, and can see the upside in Buffalo’s insurgent tech scene, this program is one of the strongest regional bets on the table.
