How venture works
Accelerators
A fixed-term program that trades a standard check and equity for network, focus and Demo Day.
An accelerator is a fixed-term program, often about 3–6 months. It invests a standard check for a standard equity stake, wraps founders in office hours, and usually ends in a Demo Day where the batch pitches investors. Famous names include Y Combinator and Techstars, plus many regional and vertical programs. Quality and terms vary enormously.
The big idea
A short, intense residency with a tuition paid in equity, not cash, is the picture. You buy a peer group, a calendar and a brand. The analogy breaks on a mediocre program: 8% for little access is expensive tuition, not a network.
Evaluate four things:
- Equity cost vs cash in — and any fees. YC advertises that it does not charge program fees; some others do.
- Network quality for your market — B2B enterprise, consumer and bio are different rooms.
- Partner time and alumni density
- Pressure — compressed time helps some teams and breaks others
Trade-off
A top accelerator's network and signal can dominate a slightly worse equity percentage. A weak program that takes 8% for little access is a bad trade. Default: only do programs whose alumni you would hire or raise from.
Walking through it
Demo Day (or its async equivalents) concentrates investor attention on a batch. The point is not to close wired money on stage. The point is to create a market: many investors see the same companies in a short window. That produces parallel conversations, social proof and time pressure — the ingredients of a clean seed process. See running a fundraise.
How to use it:
- Treat the pitch as a trailer. Book follow-ups.
- Defer tire-kickers until you are ready to run a real process.
- Raise on standard paper; novelty terms slow closes.
- Pick investors for help and reputation, not only valuation. You cannot easily fire a bad seed investor.

| Factor | Questions |
|---|---|
| Cash in | How much wires, and when? Any fees deducted? |
| Equity out | Fixed % vs SAFE with a cap? MFN or pro rata? |
| Help | Named partners, intros, hiring, follow-on brand? |
| Constraints | Relocation, IP issues, side letters? |
Program A: $100k for 8%, plus $20k in mandatory vendor credits you did not want. Effective cash ≈ $80k for 8%. Program B: $500k on a YC-like structure with real partner access, fully diluted ownership near 9%. The capital and network can dominate A's "cheaper" headline if A cannot help you raise or sell.
Regional programs can be excellent for regulated industries or local go-to-market. They are weak when the Demo Day audience cannot write your next check.
Common mistakes
- Paying 8% for a brand nobody in your market respects. Alumni references from your type of company matter more than famous winners.
- Trying to close the round on stage. Demo Day opens a process. Follow-ups close it.
- Selling 30% one SAFE at a time because every meeting felt flattering. Set a round size first.

What is Demo Day actually for?
To create a market of parallel investor conversations, not to wire money from the stage.
Program A takes 8% for $80k effective. Program B takes ~9% for $500k plus a real network. Which cost more?
A, if B's network and capital actually help you raise or sell. Headline percent is not the price.
Key takeaways
- Accelerators trade equity for a fixed term, a network and a forcing function.
- Only pay equity for programs that clear a high bar in your market.
- Demo Day is a market-making event; close on standard paper in follow-ups.
