Accelerators outside YC worth applying to

• The database holds 323 US accelerator records; 181 list pre-seed.
• Judge a program by what you get per point of equity, not by its fame.
• Ask alumni, not staff, which investors actually write checks after demo day.
• Zero-equity programs give support and visibility, but you still need to raise.
• Skip the accelerator if you already have investor access and fast growth; recreate the structure yourself.

Why look beyond the best-known programs

A handful of accelerators get most of the attention, and their acceptance rates reflect it. For a founder in Columbus, Birmingham, Omaha or El Paso, the more useful question is not "which program is most famous?" but "which program will put me in front of investors who back companies like mine, at a price I'm willing to pay?"

The accelerator field is broad. The Zalarma investor database, as of 2026-11-01, holds 323 US accelerator records, and 181 of them list pre-seed as a stage. They show up most often in records tagged B2B SaaS, consumer, fintech and healthcare. Many are regional, sector-specific or run by universities, corporations and state-backed organizations, and many accept founders who have no prior investor connections. See accelerators in the database.

The main types of programs

Programs to know, as described on their own sites

These examples illustrate the range. Terms change, so read each program's current page before applying.

• Techstars. Runs mentorship-driven three-month programs in many cities and verticals. Its investment terms page describes a $220,000 day-one investment for companies accepted into future programs: $200,000 through an uncapped MFN SAFE and $20,000 through a post-money convertible equity agreement for 5% common stock.
• gener8tor. Runs investment accelerators across several states. Its Wisconsin program page states that selected teams receive a $100,000 investment for 7.5% equity using a SAFE.
• MassChallenge. Describes its programs as zero-equity: it takes no stake in participating startups and runs sector programs, including health-focused ones.
• Alchemist. Describes itself as an early-stage venture firm backing deeply technical teams toward enterprise traction, with a structured founder program.
• Rev1 Ventures. A venture studio in Columbus, Ohio, that describes providing startups with services, space, mentoring, connections and capital.

Beyond these, look for programs run by your state's technology development organization, your nearest research university, hospital systems (for health startups), utilities and energy companies (for climate) and large regional employers. Many of them never trend on social media but have deep local investor networks.

How to evaluate a program before you apply

The right question is what you get per point of equity. Score each program on six things:

1. The deal. Cash amount, instrument (SAFE, note, common stock), equity percentage and any pro rata or MFN rights. Model the dilution with the SAFE dilution calculator.
2. Investor access. Which investors attend demo day, and which ones have written checks into recent cohorts? Ask alumni, not staff.
3. Sector fit. Do the mentors and corporate partners know your customers?
4. Follow-on rate. What share of recent companies raised a seed round within 12 months? If a program can't tell you, ask three alumni.
5. Time cost. Required weeks in person, relocation and weekly hours. A program that pulls you away from customers for three months is expensive even if it's free.
6. Alumni network. Will alumni take your call in two years? That network often outlasts the program.

How to write a strong application

• Lead with progress. Customers, pilots, revenue or usage in your opening two sentences. Programs pick momentum.
• Be specific about the problem. "Rural clinics lose about 20 staff hours a week to insurance verification" beats "healthcare is broken." Hypothetical example.
• Explain why your team. Domain experience and how long you've worked together.
• Record a short, plain video if asked. Clarity beats production quality.
• Get a referral from an alum if you can. Many programs track who referred whom.
• Apply to several. Treat applications like any other pipeline and stagger deadlines.

Read the terms like an investor would

Accelerator deals are small, but they sit on your cap table for the life of the company. Before you sign, check four things in the documents, not the brochure:

• Instrument. A post-money SAFE, a pre-money SAFE, a convertible note and common stock all dilute you differently. A post-money SAFE fixes the investor's percentage at conversion; other instruments can shift it. See SAFE vs priced round.
• Cap or no cap. An uncapped SAFE with a most-favored-nation clause converts on the terms of your next round; a capped one converts at the cap if the round prices higher.
• Extra rights. Pro rata rights, information rights and participation rights in future rounds are common. They are usually reasonable, but know them before your seed lead asks.
• Program fees. Some programs deduct services, space or fees from the investment. Ask what cash actually reaches your bank account.

Then run a simple test: if the program's cash disappeared, would its network and structure still be worth the equity? If yes, it's a good deal. If you're only there for the check, compare it with raising the same amount from angels on your own terms (how to find angel investors).

Do you need an accelerator at all?

An accelerator is most valuable when it gives you something you can't easily get yourself: investor access if you have none, sector partners, or structure if you're a first-time founder. It's less valuable if you already have a lead investor interested, strong local angel relationships, or revenue growing fast enough to raise directly.

If you skip one, recreate the parts that matter: a target list of 60–100 investors (how to build one), a peer group of founders a stage ahead, a weekly operating rhythm, and a set date to start fundraising (fundraising timeline).

Make demo day count

Demo day is a starting gun, not a finish line. Before it, list the investors who attend and research which ones fit your stage and check size. After it, follow up within 24 hours with your one-pager (template) and a specific ask. Most rounds that start at demo day close in the weeks after it, through follow-up meetings and introductions from fellow founders.

Accelerator checklist

• Shortlist five programs across at least two types (investment, zero-equity, sector, regional).
• Write down each program's deal, equity cost and time commitment.
• Talk to two alumni per program about investor access and follow-on funding.
• Model dilution for each offer.
• Prepare one strong application and adapt it per program.
