Rather than competing for allocation in rounds someone else assembled, this play creates the round. Accelerators exist to teach founders how to put a company together, recruit, iterate the idea, ship an MVP, measure customer growth, approach first customers, and know when they are ready to raise. An angel can supply exactly that, provided they put in the time. You ally with technical builders before the seed round and become their shadow business co-founder — doing the assembly work that otherwise costs a founder half or two-thirds of the company to an outside commercial partner. In exchange you put in the first money on terms you set, potentially take common equity alongside the investment, and secure pro rata rights that let you follow on. Later you help recruit the commercial partner for five percent instead of fifty. Output: proprietary deal flow at pre-seed prices, favourable terms, and a compounding claim on later rounds.
Origin
Described by Naval Ravikant on the Naval podcast in response to a question about whether an angel can still build a brand at the pre-seed stage, before or alongside the accelerators.
Core principles
- 01If the best deal flow isn't available to you, create it yourself.
- 02Seed valuations now sit where A rounds used to be, so the edge moved earlier.
- 03Accelerators sell know-how, not capital — and an angel can supply the same know-how.
- 04Technical builders routinely surrender half the company to whoever assembles the business.
- 05Getting in first lets you set terms, back the team, and secure pro rata rights.
How to run it
- 1
Target builders pre-company
Look for technical entrepreneurs who can build the product but have not yet assembled the company. This is where valuations are lowest and your contribution is largest.
Pro tip The so-called seed range now prices like the old A round, so the real edge has moved to pre-seed.

Do the accelerator's job yourself
Supply the know-how an accelerator would: how to put the company together, how to recruit, how to iterate the idea, when it is ready for investors, how to ship an MVP, how to measure growth and approach first customers.
Watch out This only works if you actually put in the time — the value is the labour, not the label.
- 3
Put in the first money
Invest the first small cheque alongside the work, at a valuation set before any competitive round exists.
Pro tip Because you helped create the round, you can back the team you want and set the terms you want.
- 4
Take equity for the operating work
Negotiate common equity in addition to your investment, or favourable investment terms, reflecting that you are doing business co-founder work rather than writing a passive cheque.
Pro tip Common equity puts you in the same boat as the founder, which is itself a brand asset.
Watch out Agree the split before the work starts; retrofitting it after the company is formed is far harder.
- 5
Lock in pro rata rights
Secure the right to invest your ownership percentage in every future round. If you own 5%, pro rata lets you take 5% of each subsequent raise.
Pro tip Cash-on-cash returns on later cheques are often better because you can deploy $30 million where you once deployed $3,000, and liquidity may be two years away rather than ten.
- 6
Recruit the commercial partner late and cheap
Once the product and traction exist, help the founder hire the business partner for around 5% of the company instead of the 50% they would have surrendered to assemble it at the start.
Pro tip The saved equity is the clearest, most quotable proof of what you contributed.
In the wild
A technical founder with a working prototype has no commercial partner. The default path is to bring in a business co-founder who assembles the company and raises the money, taking half or two-thirds of the equity. Instead an angel does the assembly work, writes the first cheque, and takes common equity alongside the investment. When the company later needs a commercial leader, they are recruited as a hire for roughly 5%.
→ The founder keeps a far larger share, and the angel holds an early position with pro rata rights on terms no competitive round would have offered.
The angel's original pre-seed cheque buys 5% of the company. Three rounds later, limited partners and larger funds want exposure and will pay carry and management fees to access that pro rata allocation. The angel now deploys tens of millions rather than thousands, with liquidity perhaps two years out rather than a decade.
→ A single pre-seed relationship converts into a multi-round, fee-generating position with far shorter duration on the later capital.
Common mistakes
Claiming the role without doing the work
The play is labour-intensive by design. An angel who promises company-building help and then behaves passively gets neither the terms nor the reputation.
Skipping pro rata rights
Without a documented pro rata right you lose the later, better cash-on-cash cheques, the ongoing relationship with management, and the ability to defend your position in a down round.
Waiting for the seed round to compete
Once the round is assembled you are back to fighting for allocation at prices set by whoever created it. The advantage exists only before the company is put together.
Is it for you?
Best for
Operators who can genuinely do business co-founder work and are willing to put in serious time per company.
Not ideal for
Passive investors who want diversified exposure without hands-on involvement in company formation.
