Armstrong recounts meeting roughly fifty prospective co-founders without finding a strong match. Rather than accept a merely available partner, he continued alone, entered Y Combinator, raised a seed cheque, and published a prototype on Reddit. The person who became his co-founder then reached out. His decision rule is to seek someone complementary who expands the thinking, produces learning, and leaves both people energised. If that match is absent, keep making progress and publish concrete evidence so aligned people can discover the opportunity. The mechanism works because execution provides signal about the founder, product, and seriousness of the idea. It does not guarantee that a public prototype will attract the right partner, so compatibility still needs testing before commitment.
Origin
After repeated co-founder meetings failed to click, Armstrong decided to build alone. Public progress around Y Combinator, funding, and a Reddit prototype led Fred Ehrsam to contact him.
Core principles
- 01A weak partnership is worse than temporary solo progress
- 02Visible execution gives potential collaborators more signal than an undeveloped idea
- 03Progress changes who is willing and able to join
- 04Public artifacts allow aligned people outside your current network to discover the work
How to run it
- 1
Define complementarity
Describe the capabilities and perspective the venture lacks. Include how a strong conversation should change your energy or thinking.
Pro tip Look for someone better than you in a consequential area, not a copy of you.
- 2
Reject a forced match
Do not formalise a partnership simply because the search is tiring. Continue alone when the available match does not meet the standard.
Watch out Do not conceal constraints that make solo operation unsafe or unlawful.
- 3
Build proof
Create product, user, funding, or learning progress that demonstrates serious execution. Let the work become more informative than the pitch.
Pro tip Choose proof that a potential collaborator can inspect directly.
- 4
Publish the beacon
Share a prototype, post, or result where relevant builders can encounter it. Make the problem and progress legible without overstating traction.
Pro tip Publish in the community where likely collaborators already pay attention.
Watch out Protect confidential information, security, and intellectual-property obligations.

Test the incoming fit
Evaluate whether an interested person adds complementary skill, learning, trust, and momentum. Work together before making a durable commitment where possible.
Pro tip Use a bounded project to observe actual collaboration.
In the wild
Armstrong stopped forcing co-founder dates and continued building. After Y Combinator, a seed cheque, and a public Reddit prototype created visible progress, Fred Ehrsam reached out and ultimately co-founded Coinbase with him.
→ Progress attracted a collaborator who had more evidence about the venture than an idea-stage conversation could provide.
Common mistakes
Hiring a co-founder to end the search
Search fatigue does not establish complementarity, trust, or shared commitment.
Keeping every signal private
A potential partner outside the current network cannot respond to work they cannot see.
Is it for you?
Best for
Early founders who have not found a complementary partner but can still create visible product progress.
Not ideal for
Ventures that legally, technically, or operationally cannot proceed safely without a required specialist or accountable partner.
