Reputable accelerator programs open doors for many startups, aiding them in quick and effective growth. Yet, which of them are worth entering, and what are the terms? Check out our collection of the top startup accelerators to consider applying to.

Becoming the next big unicorn is the dream of many startup founders. But with the startup failure rate being disappointingly high, it's very tough to build profitable chart-topper products, especially if you're new to entrepreneurship. Where do you get the needed guidance and help? What can serve as the "nitrous oxide boost" to make your startup's engine roar and press you into the seat as you dash toward desired growth in today's hyper-competitive business landscape?

On this page, we'll provide our collection of the best startup accelerators that have become the essential pit stop helping entrepreneurs who seek to turbocharge their businesses. We'll also go over the possible benefits and challenges of entering such programs and the additional perks entrepreneurs can get hold of.

What Are Startup Accelerators?

An accelerator isn't just a popular startup term, such programs are designed to help startup teams take their business to the next level. Hence, accelerating growth and development is the main aim.

Typically, the duration of an accelerator program is fixed. On average, it lasts three months (but may vary from one accelerator to another, at times, it can last up to six months). Depending on the accelerator, the programs are run a few times a year, often in cohorts.

The specific areas of focus (e.g., certain niches the accelerator specializes in or is involved in) could differ as well. Therefore, some accelerators are tailored around a distinct industry or sector like FinTech, EdTech, Healthcare, SaaS, or others. Moreover, the application process is usually quite difficult, with the average applicant selection rate below 3%.

Assisting teams with startup scaling is exactly what accelerators do. Throughout the program, they give startups the support, resources, mentorship, and guidance they're craving, helping them grow and develop their products and businesses. Yet these programs are highly intensive not only in terms of pace, they're demanding, challenging, pushing you through the limits, and a lot may be controlled by the accelerator.

Importantly, participation generally implies that the teams already have a product or launched MVP with some traction. Unlike incubators, accelerators are all about taking the business a step further instead of getting it off the ground. Hence, they're generally interested in more mature, inspiring products and those who are at later stages of startup development.

At times, they even provide funding, investing in select projects. Yet accelerators aren't fairy godmothers for startups. Participation comes at its own price, that is, usually teams have to provide startup equity of up to 10% in return for the gained knowledge and help.

Why Do Startups Apply to Accelerators?

Getting accepted into a reputable program can trampoline a startup and its product to success. Dozens of renowned companies got their spotlight and went global after going through top accelerator programs like Y Combinator, including such names as Coinbase, DoorDash, and even Stripe (which is among the best payment gateways used by thousands around the world today).

‍What are the gains? Here are some things startups can get a hold of from accelerator programs:

  • new skills and fresh perspective;
  • business advice, consultations, and guidance;
  • allocating growth areas or ways to expand operations;
  • aid with feature prioritization and product development decisions;
  • assistance with vitals like product promotion and building a strong user base;
  • help with business planning and refining the business model;
  • valuable connections, partners, and networking opportunities;
  • sometimes even additional funding.

In the end, startups can achieve a lot more during a few months than they could have in a couple of years. It's like a growth stimulant injection when entrepreneurs get invaluable insights that would have been impossible to obtain otherwise. Not to mention that many programs finish off with Demo Days, where startups get the chance to present their projects to raise funds and pitch investors.

And as you might have guessed, there are hundreds of startup teams competing to secure their spot in the programs, but getting in isn't that easy. It's tough to get admitted, as accelerators are picky about who can get in, expecting at least a built MVP of decent quality and traction. But if the team makes the cut, this can really change the game.

Matching Platforms for Co-Founders Based on Accelerators

It's no secret that there's a specific tendency when it comes to startups: teams that strike a tech and non-tech founder balance are likelier to achieve success. Such co-founder duets or combos work well because the founders complement one other's skills (each has ample expertise and background in versatile business spheres). So, how else can accelerator programs for entrepreneurs be beneficial for you?

Matching Platforms for Co-Founders of Startups

If you haven't heard of matchmaking platforms, then note that some of them even exist internally within startup accelerators. Co-founder matching platforms were especially designed to help founders find like-minded co-founders to partner with. Such platforms are a safe space for people to meet suitable potential founders by connecting with those in the network who have similar aspirations and complementary skills.

But don't think of these matchmaking platforms as "Upwork for co-founders", as it's not really about hiring. Consider them more of a "Tinder for co-founders" aimed at long-term relationships that'll last in the business realm. But there's more to these tools than a swipe to the right to find an ideal match.

Here are several prominent examples of сo-founder matching platforms on the basis of accelerators:

  • Y Combinator Co-Founder Matching Platform β€” available via their Startup School program. Individuals create and fill out their profiles, marking what they are interested in and what kind of co-founder they're ideally searching for. The solution has already helped make more than 100k matches all over the world.

  • CoFoundersLab β€” another popular service that lets you find you someone to co-found the company with. It holds various in-person events, lets you find a match online, and boasts of a rich community of entrepreneurs, investors, and mentors made up of over 650k users in over 200 cities around the globe. It's free to join if you're seeking a founder.

Basically, the major aim is to facilitate the process of searching for founders and connecting. For instance, this could be both solo founders and teams who have good business startup ideas and would like to build products yet don't want to do it alone or lack specific skills.

In many cases, it's the tech co-founder who's missing in the puzzle. And although the candidates screened for such roles are usually experienced developers or CTOs, there are other co-founder collaboration types available. As such, non-tech founders can consider partnering up with a product studio as a technical co-founder. Such a collaboration lets you team up with an entire experienced team with both a technical and business mindset and get development services at reduced rates in exchange for equity.

And, certainly, accelerator startup programs can help you achieve your growth objectives.

However, applying to the best accelerators and even getting into the program doesn't give guarantees, a lot is up to the founders.

1. How do you decide whether to join an accelerator or not?

Startups that seek mentorship and are ready to participate in an intense and challenging program with the aim of skyrocketing their business try to apply to accelerators. Importantly, as most programs require equity, and not all startups are ready to give it up in exchange for funding and learning opportunities, it is crucial to review the terms. Similarly, the accelerator's track record, curriculum, and the industry expertise the program can offer should be evaluated as well.

2. What are the advantages of startup accelerators?

Accelerator programs offer plenty of benefits, including guidance from seasoned mentors in the business industry, valuable resources, and access to founders' networks. Importantly, they often bring in investment (in most cases, in return for equity) and provide funding opportunities.

3. When should you join a startup accelerator?

Startups can join accelerator programs at various stages of their development, as some programs even accept seed-stage teams. However, to raise the chances of getting accepted, a startup needs to provide proof of traction and have a functioning product. More mature startups can use accelerator programs to boost their product and business, hence, they join them for faster business growth, quick scaling, entering new markets, and getting additional investment opportunities.

4. How do you apply to a startup accelerator?

The application rules differ in every accelerator, yet most begin by filling out a form or detailed application on the official website. Some accelerator applications are accepted all year round, while others have strict timing. If the application gets selected after initial screening and review, the startup is usually invited to an interview (at times in person).

5. How much time do accelerator programs take?

As a rule, accelerator programs run throughout a specific limited time frame. On average, the program lasts a fixed 3 months, but the duration may vary (e.g., could sometimes be extended up to 6). The selected startups receive guidance on how to scale the product to the next level and may be given funds.

6. How do accelerators choose startups to finance?

In most cases, the startups that get selected have to have potential and be a good fit in terms of the accelerator's or program's industry in focus. Accelerators evaluate applications, reviewing such factors as the team, the product or service itself, the market opportunity it has, its viability, traction, and growth potential.
