Accelerators are the fastest path to capital, mentorship, and a curated network. But the price is dilution. And most founders negotiate that price without a clear picture of what the market actually looks like.
Using official terms pulled from each program's site and verified filings, we analyzed the current deal structures of 23 of the world's most cited accelerators. Here is what the numbers actually say.

Headline Statistics
Across the 17 programs that publish a specific equity percentage:
- Median equity taken: 7%
- Mean equity taken: 7.3%
- Range: 0% (four programs) to 15% (NFX full round)
- Most common band: 5% to 10%, where 14 of 17 programs cluster
- Equity-free programs: 4 of 23: MassChallenge, StartX, Google for Startups, and Plug and Play's core program tier
Cash investment varies by more than 60x across the full set, from Alchemist's roughly $30K net to PearX's $2M ceiling. That spread matters more than most founders realize when comparing programs side by side.
The Four Dilution Tiers
The 21 programs fall cleanly into four strategic buckets.
Tier 1: Equity-Free (0%)
MassChallenge, StartX, Google for Startups, and Plug and Play's core program take no equity at all. The trade-off is smaller or no direct cash check, with value delivered through network access, cloud credits, corporate pilots, or prize money. These programs exist for strategic rather than financial reasons. Google wants AI adoption on its infrastructure. MassChallenge is mission-driven. StartX is Stanford-affiliated. The incentive structure is fundamentally different from venture-backed accelerators.
Tier 2: Low Dilution (1% to 6%)
Station F at 1% is the clear outlier on the low end, functioning more as a co-working community with optional investment than a traditional accelerator. Alchemist at roughly 5%, 500 Global at 6%, ERA at 6%, and Dreamit at roughly 6% sit in this tier. These programs typically assume meaningful traction or a strong pedigree at entry, which is what justifies the lower equity ask on their side.
Tier 3: Standard Dilution (7% to 8%)
This is the modal band. Y Combinator at 7%, Entrepreneur First at 8%, Startupbootcamp at roughly 8%. When founders refer to "the accelerator price," this is what they mean. The concentration of the most prestigious global programs in this band is no coincidence. It reflects a decade of market convergence around what top accelerators can reasonably ask and what strong founders are willing to give.
Tier 4: High Dilution (10% and above)
Antler takes 10% to 12%, Flat6Labs up to 10%, and NFX FAST takes 15% when founders elect the full pre-seed round. These programs typically invest more capital or incubate companies from zero, which justifies the higher stake. Antler backs founders before they have a company. NFX's full round is a $1.5M to $3M investment. The higher equity reflects a meaningfully different level of early-stage risk being absorbed.
The Y Combinator Standardization Effect
The most important structural shift in accelerator deal design over the last two years is not the emergence of 10% programs. It is that Techstars rebuilt its deal to mirror Y Combinator's underlying logic.
- YC: $125K for 7% fixed + $375K uncapped MFN SAFE = $500K total
- Techstars (2025): $20K for 5% fixed + $200K uncapped MFN SAFE = $220K total
Both now use the same architecture: a small fixed-equity piece plus a larger uncapped SAFE that converts at the next priced round. The MFN clause in both programs means the accelerator automatically receives the best terms offered to any investor in that round, which aligns long-term incentives without front-loading dilution at an arbitrary early valuation.
a16z Speedrun uses a variation of this approach, investing $500K upfront for 10% via SAFE plus a committed $500K follow-on in the next round within 18 months. The follow-on is not guaranteed at signing and is contingent on the next round closing, which means the effective deal at entry is $500K for 10%, implying a $5M post-money valuation on the SAFE component.
Expect more programs to follow the split structure in the coming years. Founders increasingly evaluate programs on total capital available, not on the headline check, which makes the split model more competitive to advertise and more aligned in practice.
Cash Efficiency: Dollars per Percent
Raw dilution is a misleading metric in isolation. A more useful comparison is how much cash you receive per percent of equity surrendered.
| Accelerator | Cash per 1% Equity |
|---|---|
| PearX ($2M max / ~10%) | Up to ~$200K per 1% |
| Y Combinator ($500K / 7%) | ~$71K per 1% |
| a16z Speedrun ($500K upfront / 10%) | ~$50K per 1% |
| Techstars ($220K / 5% + SAFE) | ~$44K per 1% |
| PearX ($250K min / ~10%) | ~$25K per 1% |
| 500 Global ($150K / 6%) | ~$25K per 1% |
| ERA ($150K / 6%) | ~$25K per 1% |
PearX's range is the widest of any program in this dataset, from roughly $25K per point at the minimum check to $200K per point at the maximum. This reflects the program's deliberate calibration of investment to company stage rather than a standardized deal structure. A founder receiving $2M from PearX at 10% is getting dramatically better cash efficiency than one receiving $250K at the same equity percentage, which is why Pear's investment sizing conversations happen before terms are finalized rather than after.
YC remains the most cash-efficient standardized deal in the global accelerator market. At approximately $71K per point, it is 40 percent more efficient than a16z Speedrun on the upfront check, and the gap is one reason YC's acceptance rate has remained below 2 percent for years.
Regional Patterns
The geographic distribution of terms reveals strategic differences that are easy to miss when comparing programs in isolation.
US programs cluster around the 6% to 8% band with cash investments of $120K to $500K. The market is mature and competitive, which has driven standardization around the 7% anchor.
European programs skew lower on cash but demand similar or higher equity. Startupbootcamp takes roughly 8% for €15K in direct cash. Founders Factory takes 5% to 7% for £30K to £250K, depending on program stage. The services layer often compensates for the cash gap, but the equity cost is real.
MENA and emerging markets programs like Flat6Labs offer larger check ranges but less standardized terms, reflecting earlier-stage market development and higher perceived risk at entry.
Corporate-backed programs, including Plug and Play, Wayra, Google for Startups, and Station F, lean equity-free or ultra-low-equity because their returns come from strategic partnership value and ecosystem positioning, not financial upside on the equity itself.
What Founders Should Actually Compare
Equity percentage alone is the wrong metric. Four variables determine the real value of any accelerator deal.
Total dollars in the bank, not just the headline check: YC's uncapped MFN SAFE is often worth more than the $125K fixed portion at a strong next round. a16z Speedrun's $500K follow-on commitment adds meaningful value if the next round closes within the 18-month window. A founder who prices either program at its upfront cash number is significantly undervaluing the deal.
Fixed versus convertible structure: Fixed equity, like YC's 7% and Techstars' 5%, is priced now, at whatever implicit valuation the check implies. SAFEs convert later, often at better effective terms for the founder if the next round is at a strong valuation. Both a16z Speedrun and PearX use SAFE-based structures, which means the actual dilution depends on the next round's terms.
Hidden fees that reduce net cash: 500 Global deducts a $37,500 program fee from the $150K headline. Antler deducts roughly $65K in services fees. Your net cash is smaller than the number in the marketing material. Always model the net figure, not the gross. PearX and a16z Speedrun do not charge program fees, which is worth noting in their favor.
Follow-on rights and pro-rata: YC, Techstars, a16z Speedrun, and PearX all reserve pro-rata participation rights in future rounds. This is not a cost at signing, but it shapes the cap table for years. Every time the company raises, the accelerator has the right to maintain its percentage, which affects how much room exists for new investors and at what price.
The Bottom Line
The global accelerator market has effectively split into two pricing tiers defined by VC affiliation.
Independent programs and those without deep VC backing have converged on the 7% anchor, with the remainder of value delivered through uncapped SAFEs. YC and Techstars are the clearest examples of this model, and both have refined their structures to be founder-friendly in ways that make the 7% feel increasingly fair given the capital and network on offer.
VC-affiliated programs, most notably a16z Speedrun and PearX, have settled at approximately 10%, with larger checks and embedded operator support justifying the additional dilution. These programs are not charging more arbitrarily. They are offering meaningfully more embedded support, larger capital commitments, and direct access to a venture firm's full partner network, which has real downstream value at the seed and Series A stage.
Programs that charge meaningfully more than 10% tend to be inception-stage incubators where founders trade higher dilution for the benefit of being built from zero. Programs that charge meaningfully less than 7% tend to be either running corporate strategy plays or already require substantial traction at entry.
For most founders, the real question is not how much equity they will give up. It is the quality of network, capital, and operational support they can access for the dilution they are comfortable surrendering. On that measure, the 7% to 10% band is where the best risk-adjusted value sits across the global market, and it is not a coincidence that the most sought-after programs in the world have all landed somewhere in that range.
The data does not tell you which program to pursue. It tells you how to compare what you are being offered against what the market actually looks like. That comparison, made clearly and before signing anything, is one of the most important decisions a founder makes in the first year of building.
