Y Combinator writes the bigger check and sells its network and Demo Day; Techstars takes a smaller fixed stake and runs mentor-led programs in many cities and sectors. On their published terms, YC invests $500,000 for 7% plus an uncapped SAFE, and Techstars $220,000 for 5% common plus an uncapped SAFE. Choose by stage, location and network.
The two deals, term by term
Both accelerators publish their standard terms. These are the versions on their websites as of October 2026; check again before you sign, because both have changed their deals before.
Y Combinator (ycombinator.com/deal):
$500,000 in total, with no fees charged to the company.
$125,000 on a post-money SAFE for a fixed 7% of the company.
$375,000 on an uncapped SAFE with a most-favored-nation (MFN) clause. It takes the best terms, such as the lowest valuation cap, of the next SAFE the company issues. YC's own example converts it to 2.5% at a $15 million post-money cap.
A pro rata right to invest in later rounds.
Techstars (techstars.com/investment-terms, announced April 17, 2025, for programs from Fall 2025):
$220,000 in total, with no fee to join.
$20,000 on a post-money convertible equity agreement that becomes 5% of the company in common stock, counting the existing option pool, once the company closes a priced round of at least $1 million.
$200,000 on an uncapped MFN SAFE. Techstars' own example converts it to about 1% more ownership in a round at a $20 million pre-money valuation.
A side letter with pro rata, drag-along and some reporting obligations.
Asia-Pacific programs invest $120,000 instead: the same $20,000 piece plus a $100,000 MFN SAFE.
Techstars invests in US corporations or approved foreign equivalents, so some companies need to flip into a US parent first.
What do the terms actually cost a founder?
The fixed pieces look very different. YC's $125,000 for 7% values the company at about $1.8 million post-money. Techstars' $20,000 for 5% values it at $400,000. Neither number means much on its own, because each accelerator is really paying for its stake with the program, and the bigger cash amount comes through the MFN SAFE.
A like-for-like example helps. Say the company's next SAFE has a $15 million post-money cap. YC would then own about 7% plus 2.5%, or roughly 9.5%. Techstars would own 5% plus about 1.3% ($200,000 divided by $15 million), or roughly 6.3%. YC's stake is larger, and so is the cash: $500,000 against $220,000. Both stakes are diluted later by the priced round, and Techstars' 5% is explicitly diluted by new money and option-pool increases.
The practical question is whether the extra cash and the YC network are worth roughly three more points of the company to you. For a team that needs runway and plans to raise soon after Demo Day, often yes. For a capital-efficient team that mainly wants mentorship and customers in its own region, often no.
How the programs and networks differ
Y Combinator runs four batches a year, in Winter, Spring, Summer and Fall. Each batch is about three months, takes place in person in San Francisco, and ends with Demo Day in front of a large investor audience. The value founders cite most is the alumni network: other YC companies become early customers, hiring channels and sources of advice. YC also lets companies that did another accelerator apply, though it expects more progress from them.
Techstars runs three-month, mentor-driven programs led by managing directors, many of them tied to a city or an industry and some built with corporate partners. The mentor network and the local investor community around each program are the main draws. The list of active programs changes from year to year, so check which ones are taking applications for the next cohort, and read that program's terms: some regional programs differ.

Which accelerator fits which startup?
Lean toward Y Combinator if:
You are going after a very large market and plan to raise a seed round right after the program.
You can be in San Francisco for three months.
Your early customers are likely to be other startups, where the alumni network does the most work.
Lean toward Techstars if:
You want to stay in or near your home market, and a program there matches your sector.
A themed program gives you access to corporate partners who could become customers.
You value structured mentorship and want a smaller fixed stake.
Consider neither if you already have strong investor demand and revenue. Accelerator equity is the most expensive money you will raise if you don't need the network, and many companies build well without one.
A note on where this comes from. I'm not a YC or Techstars alum; the accelerators on my record are Stanford StartX, 500 Startups, Founder Institute, Betaworks Vision and Quake. So this comparison is built from the two programs' published terms, not from inside either batch.
What should angels read into each badge?
From the investor side, an accelerator brand is a filter, not diligence. Demo Day rounds move fast and are often priced for the brand, so the work is the same as any seed deal: the team, the market, real usage, and terms you can live with. The YC network does help companies find customers and talent, and Techstars companies often have a local investor base behind them. Neither replaces your own read of the founders.
How to apply to either one
Both programs accept only a small share of applicants and say little about exact acceptance rates, so treat third-party percentages with care. What helps is the same for both: a clear problem, proof that users want the product, and a team that can explain why it is the right one to build it.

Frequently Asked Questions
Q:Is Y Combinator better than Techstars?
Neither is better for every company. YC offers more cash and a larger, more concentrated network in San Francisco; Techstars offers a smaller fixed stake and programs closer to where many founders already live. The right one depends on your stage, sector and where your customers are.
Q:How much equity does Techstars take in 2026?
Under the terms announced in April 2025, Techstars receives 5% in common stock through a $20,000 convertible equity agreement, plus whatever its $200,000 uncapped MFN SAFE converts into. Its own example puts that SAFE at about 1% more in a round at a $20 million pre-money valuation.
Q:Can a startup do both Y Combinator and Techstars?
Yes. YC's FAQ says companies that went through another accelerator can apply, though YC expects them to have made more progress. Doing both means giving up equity twice, so it only makes sense if the second program adds something the first did not.
Q:Do I have to move to San Francisco for YC?
For the batch, yes: YC's FAQ says the batch takes place in person in San Francisco. After the three-month program, founders can base the company wherever they want.
