Finding a startup incubator or accelerator in the USA that’s a perfect fit for your startup can be tricky. There are 2,301 Accelerators & Incubators in the US. With this amount, it is pretty easy to get lost and choose the wrong one. Here are some factors you need to consider before making the right decision:
  • The amount of funding they provide vs. the amount of equity they’ll take.
  • Profiles of the mentors and the industry they specialize in.
  • How many startups they’ve funded.
  • The community around it.
  • The percentage of startups they accept and the difficulty of the application process itself vs. what they can do for you.

Finding the right accelerator as well as participating in it might be a time-consuming process, that requires your full commitment and understanding on how it will help to grow your business. We decided to give you a quick overview of the top-5 most popular accelerators, their requirements, and their differences. It might help you to find answers during the evaluation process.

Difference between startup accelerators and incubators

Both startup incubators and startup accelerators offer support to early-stage startups and entrepreneurs. But they do have differences.

Astartup incubator is a collaborative program designed to help new startups succeed. Incubators help entrepreneurs solve some problems commonly associated with running a startup by providing workspace, seed funding, mentoring, and training. The sole purpose of a startup incubator is to help entrepreneurs grow their businesses.

Conversely, accelerators focus on speeding up the growth of a startup that has already built and launched an MVP. Their product is already in the hands of early adopters and they’ve achieved some sort of traction.

Y Combinator

The most famous startup accelerator on the list, Y Combinator has launched over 4000 startups. Portfolio companies include Stripe, Airbnb, Coinbase and Twitch.

Y Combinator will invest $500k when you successfully join their cohort. This payment is made on two separate safes (Simple Agreement for Future Equity):

  • $125k on a post-money safe in return for 7% of your company.
  • $375k on an uncapped safe with a Most Favored Nation provision.

You can apply to Y Combinator online. Your application will only be considered if you, as the founder, have at least 10% equity in your startup.

After finishing this procedure, you and your team will be requested to participate in an interview.

Recently, as part of Vibranium.VC’ Softlanding program for startups, we discussed the leading accelerators and the typical mistakes founders make when submitting applications to YC. Below are some of the mistakes we talked about:

  • Startups often fail to carefully read the questions, which can lead to some questions being left unanswered or the inclusion of irrelevant information in their answers.
  • Responses may contain grammatical and stylistic errors, which can negatively impact the overall quality of the application.
  • The company’s description goes beyond 50 characters, which may not meet the application requirements.
  • Some startups tend to reuse the same answer for multiple questions, which can indicate a lack of attention to detail and a failure to address the specific requirements of each question.
  • The length of the video exceeds one minute and the sound quality is poor.

If interview is successful, you’ll officially join the YC batch. During the 3-month batch, you’ll still have access to all mentorship, guest speakers, group office hours with other companies on your batch and the famous Demo Day.
