Ignore social proof and back your own conviction

Marcelo Claure · Jul 31, 2023

Never invest in something you don't truly understand, and never invest because everyone else is investing

He broke this golden rule out of FOMO with the $150M FTX investment, driven by not wanting to be the only one left out while running crypto/blockchain at SoftBank

A great fund leading the next round is a strong signal, but relying on that validation is a luxury; conviction often has to be built internally when no top fund will touch the company

At the UiPath bridge no great fund was interested, so they had to build conviction themselves

Investors should be conviction-driven and invest regardless of who else is in the round

Conviction should come from belief in the founder, not from the presence of other investors

When your gut says a deal is off, you should pull out of it entirely — he now does, after having overridden that instinct on a $5M investment

He had the feeling something was off, called the pedigreed lead investor, still did the deal, and regrets it

Oren Zeev · Feb 2, 2026

Investors should suppress or ignore social proof and other investors' opinions and invest on their own conviction

Venture returns are driven by winners, not losers — a loss costs 1x while a win can be 100x, so being right 50% of the time on high-conviction bets is a great result

Strategic investor presence can be part of the investment thesis not mere social proof

Harry Stebbings · Jul 15, 2024

When a truly great investor brings you into a round, you should not second-guess them.

He questioned Elad Gill on Vanta at seed because he didn't understand SOC 2 compliance and missed the deal.

When a top-tier firm like Benchmark or Sequoia wants to invest aggressively in one of your portfolio companies, that is a strong enough signal that you should at least consider exercising pro rata — blindly following them is 'closer to right than not'

His own track record — Demandforce with Benchmark, Twitch with Bessemer, Lyft with Mayfield/Founders Fund/a16z, Okta with a16z, Greylock and Sequoia — shows the top winners were the ones the best firms followed into

Scope: best firms following is not a guarantee; some such companies still failed

When a top-tier investor joins the board of a hot company, the next round is meaningfully de-risked and you should put in as much as you can get

Kassar was so good and so well prepared he'd have raised from anyone he pitched; once Mark joined the board the Series B looked de-risked, and demand was so strong that Iris was trying to buy more the moment their check cleared

Scope: specific to exceptional founders in hot rounds

Jack Zhang · May 27, 2025

Sequoia's insistence on Tencent joining was defensible rather than a lack of conviction, because at Series A with zero revenue their conviction rested on Tencent and Mastercard becoming the company's two largest customers

A Series A normally requires product-market fit and revenue; here the strategic investors were the intended source of that revenue, so their participation was the substance of the thesis

Scope: specific to a Series A with no revenue and strategic investors as prospective customers

Also on the record

Social validation in early rounds is dangerous because a trivially small check from a large fund manufactures an artificial premier-brand signal that other investors follow

$5M is coffee money to a billion-dollar fund, but a CPO angel then writes $50k just because that fund is in, and the round suddenly looks like an A-star deal built from nothing

19:43 Small checks from big funds manufacture false brand signals that others follow
