Joining an accelerator can be a game-changer, providing startups with mentorship, resources, and funding at a key moment in their development.

What is a startup accelerator?

Accelerators are intensive business growth programmes that typically last for three to six months. Joining an accelerator programme gives founders access to mentorship, guidance, resources, networking opportunities and a small amount of funding – usually in exchange for around 3-10% of their company’s equity.

For most accelerators, you’ll need more than just an idea to apply. You’ll need a prototype and often the first iteration of your product or service with initial market traction. If you’re accepted into an accelerator programme, startup advisors and seasoned entrepreneurs can help you refine your product, business model and pitch. They’ll also connect you to investors, giving you a better chance of raising seed funding.

Startup accelerator vs. incubator

Accelerators and incubators are both designed to help founders build a successful business. However, there are some key differences between these two programmes.

Accelerators focus on accelerating the growth of an existing startup – usually at the seed stage – that already has a minimal viable product (MVP) and a founding team in place. Accelerators are often cohort-based: only a certain number of startups get accepted at any one time, and they’re guided through the structured programme together. If you join an accelerator, you’ll receive actionable feedback to improve your product and business plan, as well as funding in return for a stake in your company.

Incubators are generally less structured than accelerators and aimed at very early-stage startups (e.g. pre-seed). These programmes provide the environment and resources needed to transform an initial idea into a viable business. Unlike accelerators, applying to an incubator doesn’t require an MVP, business plan or founding team.

When should you join a startup accelerator?

There’s no right or wrong time to join an accelerator, but you’ll probably find it more beneficial once you have product-market fit (PMF) and are preparing for your first funding round.

Since accelerators are ultimately designed to help founders improve their product and develop a business plan with the goal of securing investment, they’re less useful for companies that have already raised a priced round (such as a Series A). Most programmes end with a “demo day”, allowing startups to pitch to a variety of investors within the accelerator’s network.

How to apply to a startup accelerator

The first step is to identify the right accelerator and check whether your startup meets the eligibility criteria. While many accelerators look for companies with an MVP and some evidence of market traction, each programme has a particular area of focus and expertise. You’ll want to find one that aligns with your industry, growth stage and business goals.

Keep in mind that startup accelerators are often oversubscribed and highly selective; to get accepted onto a programme, you’ll need a well-crafted application that helps you stand out from the competition.

Here are some tips for nailing the application process:

Applying for an accelerator isn’t just about showcasing your startup's potential; it's also an opportunity to reflect on your business strategy and goals. A well-prepared application can help you clarify your vision and roadmap, as well as increase your chances of getting accepted onto a reputable programme.

How do accelerators affect company valuation?

The impact of joining a startup accelerator on your company valuation is multifaceted, starting with equity dilution. Typically, accelerators ask for about 3-10% equity in exchange for investment and support – including access to invaluable resources, mentorship and potential investor connections. Equity dilution is a natural part of startup growth that can affect your financial stake in the company and how much control you have, so it’s important to learn how to manage it properly.

On the other hand, getting accepted into a well-regarded accelerator programme can enhance your company's market valuation. An accelerator's endorsement often signals to potential investors that your startup is a worthwhile investment, which could lead to a higher valuation when you raise your first funding round. Additionally, the growth and development you gain from the programme can boost the intrinsic value of your business. These upsides could offset any initial equity loss and drive more investor demand.
