Startup mentorship programs are hot entrepreneurial topic these days.
Thousands of founders apply to Y Combinator, Techstars, 500 Startups, etc. every year chasing the “golden ticket.” Yet few entrepreneurs understand what the data tells us about acceleration programs.
Look at the amazing story the data tells you. You can tell just by scanning the latest accelerator stats:
- Understand if a program is right for your startup
- See the real success rates behind the hype
- Make smarter decisions about your funding path
Let’s get into it…
What you’ll uncover:
- Why Accelerator Statistics Matter
- The Big Numbers Every Founder Should Know
- Top Programs Compared By The Numbers
- What The Stats Mean For Your Startup
Why Accelerator Statistics Matter
Numbers don’t lie.
Startup mentorship programs love to oversell results with their marketing. Stats help remind you what kind of return you should actually expect.
Most founders make decisions based on:
- Hype around well-known programs
- Stories of unicorn graduates
- Friend recommendations
Except for the smart founders. The ones who study the data first. Influencer Randy Gage did some great reporting on how startup mentorship programs have become a BILLION dollar industry with THOUSANDS OF PROGRAMS world-wide. With this type of growth founders have more choices than ever before. But they also have more opportunity to choose incorrectly.
Here’s the bottom line:
Once you understand the statistics at play with these programs you can eliminate the bad ones and focus on the programs that truly move the needle for you.
The Big Numbers Every Founder Should Know
Now to the good stuff.
Got an accelerator application coming up? Memorize these stats before you hit submit. Read why.
Survival Rates
This is probably the most important number…
Here’s a fun fact: startups that graduate from an accelerator program are 23% more likely to survive than those who don’t. That’s a huge increase, given that most startups die within the first few years.
However, not all programs are equal. Higher ranked programs dwarf that number.
Funding Outcomes
Getting into an accelerator can seriously boost your funding chances.
Wharton research found that graduating accelerators raised 3.4% more venture capital than unaccelerated startups. They also raised $1.8 million more VC dollars during their first year post-program. That’s a lot of capital just for going through a structured accelerator program.
The funding boost makes sense when you think about it:
- Mentors connect you to investors
- Demo days put you in front of VCs
- The program “stamp” gives you credibility
That’s a win-win-win.
Acceptance Rates
Here’s a stat that surprises a lot of people…
The most prestigious startup mentorship programs are more competitive than the Ivy League. Acceptance rates for the top programs like Y Combinator and Techstars range from 1-3%. Out of 100 applicants, only 1-3 are accepted.
Why does this matter? Because if you DO make it through, the mere act of being selected shows investors that your startup is worthy of their time.
Top Programs Compared By The Numbers
Different accelerators have different track records.
Here we will compare some of the largest companies against one another.
Y Combinator
Y Combinator is the gold standard.
YC stats are bananas. Recent stats have shown that only 93% of YC backed companies are still around. Nearly triple that of the average startup.
It gets better…
YC has invested in more than 4,000 companies with a unicorn rate of 5.5% — over twice that of other programs on average. Alumni you might recognize include:
- Airbnb
- Stripe
- Dropbox
- Coinbase
But cracking the door is tough. Acceptance rate sits at about 1.5-2%, making it one of the most competitive programs globally.
Techstars
Techstars is another heavyweight in the accelerator space.
Not only are they graduating startups, they’re graduating quality startups. Approximately 80% of Techstars’ startups are still operating, and a good portion raise follow-on funding within three years of graduation.
Techstars works because they focus on:
- Hands-on mentorship from operators
- Industry-specific programs
- A strong global network
This also makes them attractive to founders who desire more specialized attention than YC.
500 Startups
500 Startups (now called 500 Global) rounds out the top three.
They have a startup survival rate of approximately 81%. This isn’t too bad, but still lower than YC. They invest mostly in seed-stage companies. They’re international which appeals to many foreign founders.
What The Stats Mean For Your Startup
So what should you actually do with all of this information?
Here are three statistics that will help you understand startup mentoring programs.
Not All Programs Are Equal
This is the biggest takeaway.
The top 5-10 programs appear to produce very different results than the hundreds of smaller, lesser-known accelerators. Approximately 45% of Y Combinator companies raised a Series A, versus 33% of seed stage startups overall. That’s a big difference.
If you’re going to take equity, pick a program that makes a difference.
Selection Matters More Than Marketing
Some accelerators try to attract founders with flashy pitches, big offices, and famous mentors.
But the data shows that the real value comes from:
- Mentorship quality
- Investor connections
- Network strength
Don’t get distracted by the surface-level stuff. Look at what graduates have actually achieved.
Equity Cost vs Value
Most accelerators take 5-10% equity in exchange for their support.
Is it worth doing an accelerator? Depends on the accelerator. For YC, given their 93% success rate and connections to top VC’s, almost always yes. For an unknown, small program with poor track record, probably not.
Do the math before signing anything.
Final Thoughts
The statistics around startup mentorship programs paint a clear picture.
Accelerators can significantly boost your odds for survival, funding and success. However, there’s a big difference between the best programs and everyone else. Here’s a quick refresher:
- Check survival rates before applying
- Look at funding outcomes for graduates
- Compare equity costs to actual value
- Don’t get fooled by hype
The information you seek is available, if you care to look at the data. Leverage it correctly and your startup will have every opportunity to thrive.
All the work is up to you to apply, be admitted, and perform. However, understanding the statistics really puts you leagues ahead of founders who walk in unaware.
