How do startup accelerators work?

What is a startup accelerator? 

A startup accelerator is a structured program designed to fast-track the growth of early-stage companies by providing mentorship, resources and funding in exchange for equity. These programs usually run for a set period of time, typically three months. They are cohort-based, offering startups a chance to network with advisors, peers and potential investors. When you apply to a startup accelerator program, you are expected to have more than just an idea—ideally, you’ll have a prototype, a minimum viable product (MVP) or an actual product.

There are more than 200 accelerator programs in the United States and many more globally. Different programs offer different areas of focus, and they vary in cost and effectiveness. For example, Y Combinator and Techstars specialize in tech startups, while university-sponsored accelerators like Stanford University’s StartX and corporate programs like Johnson & Johnson's JLABS focus on life science and healthcare industries.

How does a startup accelerator work?

Startup accelerators offer short-term programs that focus on mentors, networking and business development. The goal is to help startups refine their business models, develop products and connect with investors through demo day presentations where startup founders showcase their products, technologies or services to potential investors, partners and the public.

Private startup accelerators can provide funding to help cover early-stage business expenses, including travel and living costs for in-person programs. However, the funds and guidance come at a price. Startup accelerators generally take 5 to 10 percent of equity in exchange for training and a relatively small amount of funding. Just as with any other equity funding, signing an accelerator agreement typically means  giving up a slice of your company—this trade-off gives the accelerator a financial stake in the company's success.

During the accelerator program:

• Founders work closely with advisors and experienced entrepreneurs to refine their product and business strategy.
• Participants receive limited funding to cover living expenses and business costs.
• The program finishes with a demo day, where startups pitch to potential investors and other stakeholders.

The purpose of an accelerator is to fast-track a startup's growth trajectory, helping founders build critical connections and refine their path to success.

Are accelerators good for startups?

For most startups, the overwhelming answer is yes. First-time founders usually need a lot of support, and an accelerator can help you by:

• Providing a playbook from past startups
• Making connections to investors
• Explaining the best ways to pitch
• Showing what a fundraising cycle looks like
• Connecting to subject matter experts who can help you achieve product market fit or even help you develop a go-to-market plan

However, you need to choose carefully so you don't end up giving away your time and equity in exchange for off-the-shelf help. While top programs boast a large roster of well-known graduates, the number of successful exits and amounts raised can drop off rapidly.

How do accelerators select startups?

Accelerators typically accept only one to three percent of applicants, focusing on startups that show:

• Strong teams: Founders with experience, cohesion and resilience
• Innovative concepts: Startups solving important problems with a clear market demand
• Competitive advantage: A unique product or service that stands out in the market
• Coachability: Founders who are receptive to feedback and guidance
• Market potential: Industries with high growth opportunities

A compelling pitch and demonstrated market traction improve the chances of acceptance.

What are the differences between startup accelerators vs. incubators?

The terms are sometimes used interchangeably, but there are well-agreed upon differences between accelerators and incubators.

Accelerators aim to do literally that: accelerate your startup's growth. Applicants will be expected to have something more than an idea, be it a prototype or product. As was mentioned earlier, accelerators provide intensive guidance, support and structure for a set period of time, most commonly three months. They'll expose you to advice from a wide range of mentors. You’ll be building toward a demo day event when you'll present your idea to potential investors and other interested parties, including press.

Incubators, on the other hand, provide a more flexible, long-term, and nurturing environment, sometimes lasting years, for startups still refining their ideas, building initial teams, and seeking product-market fit, usually without requiring equity or offering direct funding.

As an early-stage startup founder, an accelerator will likely immerse you in a high-pressure, fast-paced environment with structured milestones and frequent mentor sessions aimed at achieving quick traction and preparing you for fundraising. You can expect to refine your business model under intense scrutiny, gain exposure to a wide network of investors, and work towards a demo day presentation. Conversely, in an incubator, you'll experience a more relaxed pace, with ample time and resources to experiment with your product, develop your business model and organically build your team. Furthermore, you can benefit from a shared workspace and ongoing, ad hoc mentorship without an equity stake or the immediate pressure to scale rapidly.

What do accelerators offer startups? 

There are four major ways an accelerator can help you take a company from idea to execution:

1. Critical connections 

Well-known accelerators work closely with angel investors and venture capital firms that are looking to invest in promising business ideas. Additionally, an accelerator can introduce you to an ecosystem network dedicated to helping you progress your idea into a company. If you are new to the industry, this is particularly useful. By connecting you to a network of advisors, you can become part of a culture within a short amount of time. Being a member of this insider network can give you credibility that will help with both hiring and fundraising.   

2. Business and management mentoring 

Accelerators are instrumental in matching inexperienced founders with the right management guidance to transform innovative ideas into viable businesses. For participants, being part of a cohort of founders going through similar challenges can be an amazing experience. Such programs teach you to navigate personnel, fundraising and scaling issues. It's comparable to a college experience where the requirements are minimal, and it is up to you to make the most of it. Becoming part of a prestigious accelerator program can educate you in numerous ways, optimize you for fundraising and truly enhance early company cohesion.

Following the program's conclusion, companies often successfully raise significant seed rounds from notable investors on favorable terms. Within a year, your startup can experience substantial growth, more than tripling both your revenue and headcount. This transformative period underscores a clear distinction in your journey, marking a pivotal "before and after" due to the accelerator's impact.

3. Collaborative environment  

Whether virtual or in person, startup accelerators provide informal feedback and guidance on the technology or business concept you're pursuing. These "hackerspaces" or "makerspaces" are collaborative workspaces where engineers and creative problem-solvers can help you pivot from an exhausted idea or break down a good idea and rebuild it into something even better. Many startup accelerators focus on specific types of businesses and amass high levels of expertise within their accelerator.   

4. Access to physical space and camaraderie  

Many entrepreneurs take advantage of open coworking spaces, offices, conference rooms, workbenches and other facilities. Not only is it nice to have the space, but you can also benefit from the emotional support that comes from being alongside other team members from different projects. Everyone is facing similar challenges, and you can help one another by bouncing ideas around and engaging with CEOs and alumni.  

Choosing the right accelerator for your startup 

The key is getting into a quality accelerator. Talk to other founders who have gone through an accelerator to figure out which one is a fit for you. Other accelerators or incubators may make sense for your founding team if they specialize in your startup's sector. Leading US universities also have well-regarded accelerators, including MIT's delta v. Corporations sponsor well-respected accelerators like Johnson & Johnson’s JLABS, as mentioned above. And there are some strong regional accelerators, such as MucketLab in Los Angeles and the Entrepreneurs Roundtable in New York. 

Applying to a well-respected startup accelerator can be difficult, but the real work begins once you're accepted. Whether you're participating virtually or traveling to attend in person, be ready to set up with your team and get started.

Here's what you can expect from typical startup accelerators:

• Fast-paced days
• Educational seminars and workshops on topics like fundraising, HR, working with legal counsel, pitching practice and product development
• Group and one-on-one mentorship from industry experts, investors and successful founders
• Regular check-ins with accelerator leadership such as investors and alumni founders

You should think carefully and weigh the advantages of a startup accelerator against the cost, particularly in time and equity.

A startup accelerator can be a big distraction. You know that creating a company in any sector is an around-the-clock endeavor. Committing to an accelerator can rob you of time that could be spent building product, hiring key staff and closing sales.

Additionally, timing is everything. You may be too early for an accelerator. Alternatively, you may be too late if you have already raised venture money. And perhaps your founding team already has the depth of knowledge and experience that would make an accelerator superfluous. Consider whether your company is at the right stage to benefit.

How to apply an accelerator 

Leading accelerator programs only accept one to three percent of the thousands of startups that apply every year. The challenge is making your application stand out by being exceptionally clear and concise. Be sure you speak in terms of the value your company is providing. Don't list product features. Instead, state a more compelling benefit.

• Wrong: Google Search lets you find websites and things online. Google Maps can help you get places. Google videos can help you find videos. Google Flights helps you get cheap travel.   
• Right: Google organizes the world’s information to give you instant access to whatever knowledge you need. 

You’ll want to focus on these elements:

• Strong team: Highlight why your team is uniquely equipped to succeed.
• Innovative concept: Emphasize the problem your product solves.
• Competitive advantage: What sets your business apart? What makes you memorable? And equally important, can you describe your unique selling and value propositions in one or two sentences? 
• Coachability: Show how you'll integrate feedback to achieve results.
• Market potential: It's OK to be a small business. But be aware that startup accelerators are looking for hypergrowth in massive industries. You need to show investors that your company is in a market large enough for venture-scale returns.  

When you apply to an accelerator, your job is to first demonstrate a founder-market fit. Describe how your team's background and skills led you to a unique market insight on which to build a sustainable business, and why your team is the right one to grow and scale the business.  

Second, you need to sell your vision of this future. Share your thoughts on why this is such a compelling and exciting opportunity that led you to pursue the startup path, even given the inherent risks.

Conclusion

A startup accelerator is a structured, cohort-based program designed to fast-track the growth of your early-stage company by providing mentorship, resources and funding in exchange for a small equity share of your company. Their aim is to help you refine your business model, build your network and connect you with potential investors. Typically lasting three months, these programs are best if you already have a prototype or minimum viable product.

Like all investors, startup accelerators want to believe in you, but they are reviewing several hundred applications at once. Be concise to keep them interested. Overly wordy or buzzword-filled applications will get passed over for a lack of clarity.

Keep your application focused and easy to follow. A succinct application can help you move on to the accelerator investment board and give you another opportunity to demonstrate you have a viable product and a team that can make your pitch a reality.
