Increasing your surface area for luck

When this applies
when outcomes in any field depend heavily on chance encounters and timing rather than pure merit
The takeaway
Treat luck as a function of exposure surface, not randomness — deliberately multiply the touchpoints where the right person could find you.
Why it works
You can't engineer the exact lucky encounter, but you can increase the number of exposure points (profiles, lists, public signals) where a relevant person could discover you, raising the probability one of them converts.
One level up
Systems that make hidden signal visible compound in value because visibility itself creates the conditions for chance to act.
Where it stops holding
This stops working when the exposure channels are noisy or untrusted, so more surface area just adds clutter instead of signal.
Detail
approach: Build a graph/profile/list system that makes a person's skills and interests discoverable; treat 'coincidence of intent' matching as the real product, not credential filtering.
signals:
- unexpected introductions outperforming job boards
- people and companies converging around shared missions
- rising-star nominees nobody official would have flagged
rationale: If the system increases the odds of the right discovery happening, you don't need to predict exactly who will find whom.
In their words
I hope it's a place where you can increase your surface area for luck.
Self-select into the culture doing the mission you care about

When this applies
when choosing which environment, community, or employer to join for long-term career or network benefit
The takeaway
The long-term payoff of joining a group isn't just the job — it's the relationships formed with people pursuing the same goals, which compound into future ventures.
Why it works
Joining people working toward a shared mission puts you in repeated proximity with others who share your values and complementary skills, generating future collaborators and co-founders even if the current company isn't the ultimate vehicle.
One level up
Careers are short at any one stop, but the people met along the way are the durable asset.
Where it stops holding
This stops working when the chosen group's culture doesn't actually match the stated mission, or when the role offers no real interaction with the mission-aligned people.
Detail
approach: Identify a mission you care about, find companies/communities pursuing it, and join one even if it's not the 'ultimate' vehicle for that mission.
signals:
- you are the average of the five people you spend time with
- roles are short but the people you meet along the way persist
rationale: The relationships built while pursuing a shared mission become the basis for your next venture, independent of whether the specific employer succeeds.
In their words
If you self-select into a culture of people who are working on that mission, then you will find that it's not even just the, there's this line of careers are long, you know, roles are short, but it's the people you meet along the way that you can build the next thing with
A co-sign is a reputational bet worth more than a resume line

When this applies
when deciding whose recommendation to stake your own credibility on, in any referral or gatekeeping decision
The takeaway
The strength of an endorsement is measured by how much of the endorser's own capital (time, reputation, access) they're willing to risk on it.
Why it works
A willingness to spend your own scarce reputational capital introducing someone to a person who is hard to access is a costly, hard-to-fake signal of genuine belief in that person's quality.
One level up
Costly signals are trustworthy precisely because they are costly to the signaler.
Where it stops holding
This stops working when endorsements are given cheaply or performatively, diluting the signal value of any single vouch.
Detail
rule: Define a trust signal as 'would I introduce this person to someone I deeply respect who is extremely busy.'
threshold: Willingness to use access to a busy, high-value contact as the bar for a genuine endorsement.
rationale: This filters out low-effort praise and isolates genuinely high-conviction recommendations.
In their words
One way you could say is like, if you were willing to introduce this guy to somebody that you deeply respect, that's incredibly busy. Not most, most people can't get to, but you say, actually, this is worth your time. That's the cosine.
Dhruv's cold-apply vs. trusted-referral path into tech

When this applies
when entering any competitive field where formal application channels are overcrowded and low-signal
The takeaway
A single credible human vouch outperforms a large volume of low-trust applications because it transmits information the formal process can't capture.
Why it works
Cold applications compete on commoditized signals (resume, school) that are easy to fake or inflate, while a trusted person vouching for specific observed work supplies a much higher-fidelity signal that bypasses the noisy funnel entirely.
One level up
In markets flooded with noisy signals, trust becomes the scarce resource that actually clears the market.
Where it stops holding
This stops working when the vouching person's judgment is itself unreliable or when the opportunity requires formal credentials the referral can't substitute for.
Detail
situation: Dhruv was cold-applying on Handshake for finance internships, an exhausting low-yield process.
decision: Brent, having seen Dhruv's work at Polymarket, personally vouched for him and brought him into MTS/tech instead of requiring a formal application.
outcome: Dhruv got his real break into the tech industry through that single referral, bypassing the cold-apply funnel entirely.
lesson: Trusted vouching can substitute for and outperform formal credential-based hiring pipelines.
In their words
My first like experience in tech, as I mentioned earlier, was through Brent, seeing some of the work I'd done at Polymarket before and recognizing that I would be able to contribute at MTS.
Techagon's agent-to-agent negotiation protocol

The a16z Show — Can AI Fix Professional Networking? | Inside Cosign (October 31, 2026) · at 20:10 ▸
When this applies
when an automated assistant has rich knowledge of a principal's goals but no direct channel to act on another principal's behalf without human-mediated back-and-forth
The takeaway
The next leap in automation comes not from making one agent smarter, but from letting two agents representing different principals talk to each other directly.
Why it works
Giving agents a direct communication protocol with each other (rather than drafting emails for humans to relay) removes a layer of friction and lets matching/negotiation happen at machine speed and precision.
One level up
Removing the human-in-the-middle step between two already-automated processes is often the real unlock, not further improving either process alone.
Where it stops holding
This stops working when the negotiation requires trust, nuance, or accountability that agents can't yet reliably represent on behalf of their principals, risking bad deals made autonomously.
Detail
situation: Personal agents (e.g., Muse, which hit 10M users) could know users well but could only draft messages for humans to send, creating friction in connecting people.
decision: Techagon introduced an agent-to-agent protocol so a company's agent and a customer's personal agent could negotiate directly.
outcome: Early agent-to-agent communication appeared in customer success use cases, inspiring Cosign to pursue agent-to-agent matching for hiring and networking (my agent talks to the company's agent, or two people's agents assess 'coincidence of intent' before connecting).
lesson: Direct agent-to-agent channels can replace the inefficient email-relay model of digital negotiation/matching.
In their words
Techagon was one of the first to introduce their agent-to-agent protocol with Muse and Instinct. And their customers, who might be big companies, like a car rental company, say, and the personal user can just negotiate directly with the agent on the other side.
