How to Get Into a Startup Accelerator
Accelerators buy you a network, a deadline and a credibility stamp in exchange for equity. Getting in is less about polish than most applicants think and more about clarity: who you are, what you've built, and what's actually happening with customers. Here's how the process works and how to be the applicant who gets a yes.
What an Accelerator Actually Gives You
Three things are worth the equity: forced pace, access, and signalling. A cohort with a demo day deadline compresses a year of progress into three months. Partners and alumni open doors to customers and investors you couldn't reach cold. And a well-known badge shortcuts investor diligence for your next round.
What it doesn't give you is product-market fit or a business model. Founders who arrive expecting to be told what to build tend to get the least out of the programme.
Choosing the Right Programme
**Y Combinator** — global, highly competitive, strongest alumni network and investor signal; standard deal, remote-friendly application, three-month batch. **Techstars** — city and sector specific programmes with a strong mentor model; good when you want depth in a particular industry or region. **Antler** — invests at the pre-team, pre-idea stage and helps you find a co-founder, making it a fit for individuals rather than formed startups. **Local and sector accelerators** — often non-dilutive or grant-backed, with less signal but real local customer access.
Judge each on the same four criteria: does it reach your customers, does it improve your next round, what does it cost in equity and time, and are the partners people you'd want in a crisis. Talk to two alumni from a recent cohort before applying — they'll tell you more than any website.
What Reviewers Look For in an Application
Applications are read fast. Reviewers are scanning for a clear problem, an unusual insight into it, proof you can execute, and a reason this team wins.
The highest-signal answers are concrete: what you've built and in what timeframe, what customers do with it, how much revenue or usage there is, and what you learned that surprised you. Vague market-size statements and buzzwords actively hurt you. If you have numbers, give them; if you don't, say what you've learned from talking to buyers instead of hiding it.
Writing Answers That Get Read
Answer the question asked, in the first sentence, in plain English. Cut every adjective that isn't load-bearing. A reviewer should understand what you do after one line: "We do X for Y so they can Z."
For the founder questions, show evidence rather than adjectives: things you shipped, competitions won, unusual experience, why you specifically know this problem. For traction, include a number and a timeframe, even if it's small — "£900 MRR from 14 customers, up from 3 in June" beats "strong early traction" every time. Record a founder video that is one take, well lit, and answers the prompt in the time allowed.
Surviving the Interview
Interviews are often ten minutes, fast and interruptive. That's not rudeness, it's a test of how clearly you think under pressure. Prepare two-sentence answers to: what do you do, why now, who's your customer, how do you make money, what's your growth rate, who are your competitors and why do you win, and what's the hardest part of your business.
Know your numbers cold, admit what you don't know, and never bluff a metric. When challenged, defend with evidence or concede quickly and explain how you'd find out. Founders who argue past the point of evidence do worse than those who say "I don't know yet — here's how I'd test it."
If You're Rejected — and When to Skip It
Rejection at this stage is mostly noise; many accepted companies applied more than once. Ship, get customers, and reapply with a different set of facts rather than a reworded application. Ask for feedback, but weight real progress above it.
And consider not applying at all. If you already have customers, revenue and investor access, three months of programme overhead may cost more than the equity. Accelerators are most valuable when you're short on network, momentum or credibility — which is exactly why they suit first-time founders.
Frequently Asked Questions
Do I need a co-founder to get into an accelerator?
Most accept solo founders but prefer teams, because building alone is harder. Antler is built specifically to help individuals form teams. Solo applicants should show unusual execution speed and a plan for the first hires.
How much equity do accelerators take?
Typically 5-10% for cash plus programme, though terms vary widely. Some public and university programmes are non-dilutive. Compare the total package, not just the percentage.
Do I need revenue to get in?
No. Many accepted companies have no revenue. What matters is evidence of speed and customer insight — something built, something learned, someone using it.
Is it worth applying more than once?
Yes. Reapplying with real progress is common and viewed positively. Reapplying with the same facts and better wording rarely changes the outcome.
Are online or local accelerators worth it?
They can be, especially when they bring customers in your market or non-dilutive funding. Judge them on customer access and alumni outcomes, not on branding.
