Principle
Founder, not firm, is the core of the company
Even when you co-develop the idea from zero, the founder must remain the core — terms must be market-fair.
Saam rejects 'incubate' as a word, citing firms taking 40% for $10M. Greylock writes a bit more capital for a bit more ownership at market terms.
Defend market-fair terms even in pre-idea backing.
“who is the core of the company? Is it the founder or is it the VC firm? ...our view is to state the obvious, it''s the founder”Saam Motamedi
Principle
Three durables in a venture firm: values, brand, network
Only three things actually persist across decades in a venture firm: core values, brand-as-credibility-vouch, and the relationship network.
Saam walks through how Greylock's brand flywheel works: stake credibility on a founder → founder builds → brand grows bigger than Greylock's → flywheel reverses. He traces the 18-year arc from a 2007 outreach to Josh McFarland → Teleport → Abnormal AI → Cogent & Fable Security as proof of the network durable.
When evaluating any long-lived institution, separate the durable substrate from the fluid surface tactics.
“what are the core values and ethos of the firm? I think that gets embedded in the DNA and persists... the second dimension is the firm''s brand... and then the third is the network”Saam Motamedi
Principle
Causally impactful, not sourced — kill the attribution game
Replace 'who sourced it' with 'who was causally impactful' as the unit of credit inside a venture partnership.
Saam describes how Greylock removed the language of 'sourcing' to defuse the principal-agent problem: a senior partner's first reflex on intersecting an opportunity is to bring a younger partner in as the primary. This only works if attribution is structurally collaborative.
Audit how your firm or team assigns credit — the language is the incentive.
“We use the language, were you causally impactful to a successful investment? That could mean you sourced it, it could mean you built a prepared mind, which enabled us to make a quick decision”Saam Motamedi
Principle
Partnership size caps cohesive decision-making around ~12
Cohesive partnership decision-making has a hard ceiling around 8-13 people.
Saam ties partnership size directly to turnover dynamics: large firms create subcommittees, low performers hide, strong performers feel diluted and leave.
Treat 12 as a soft cap on full-partnership decision groups.
“we think above some group size it gets really hard to make cohesive decisions... whether that''s 8, 10, 12, 13, like we could debate that, but it''s sort of in that range”Saam Motamedi
Principle
Insularity is the death of venture
Structurally fight insularity by meeting out-of-network founders monthly.
Saam admits less serendipity surface area than nine years ago — commits to one event per week and an out-of-network founder quota.
Put a monthly out-of-network founder quota on your calendar.
“I try to make sure I meet some founders every month who are completely out of network... insularity is the death of this business”Saam Motamedi
Principle
Apprenticeship via osmosis — develop beginner''s mind through total immersion
Venture is a different business from any other business; hire for beginner''s mind and develop people through total co-presence in every decision.
Saam describes joining boards on day one, sitting next to partners in CEO interviews, and debriefing after every conversation about what was detected. The model assumes the apprentice is on a 20-30-40 year arc, so the upfront immersion cost is amortized over decades.
If you can''t put a new hire in every important room from day one, you''re not training judgment.
“I joined the firm at 23. I immediately joined a number of boards alongside my partners. I was in every conversation with them”Saam Motamedi
Principle
Inputs over outputs in long-cycle businesses
In long-cycle high-variance businesses, evaluate people on inputs not outputs — and reject good outputs with no inputs.
Greylock built an 18-input rubric across see/decide/win/build + internal partnership. They explicitly reject good outputs with no inputs because reproducibility is impossible.
Write down your inputs before luck arrives.
“if we agree on what it means to be a good investor... if someone''s performing on those things, we can take long-term view on people and hopefully people get lucky early on. But if they don''t and they keep executing the inputs, we''ll take the bet that luck will come their way”Saam Motamedi
Principle
Decision speed scales with clarity, not memo length
Investment decisions in hours are possible if you''ve done the prepared-mind work upfront — long memos are a substitute for missing context.
Saam contrasts 15-page memo eras vs current 2-paragraph eras at Greylock and concludes memo length doesn''t track decision quality for first-check investing.
Move rigor upstream — into prepared mind.
“We only care about two things. One is who''s the person? And the second is what''s the general area in which they''re building it? And like if those two things are bright green, we''re ready to invest and we''ve made decisions in hours”Saam Motamedi
Principle
Take execution risk, not market risk
The best early-stage bets have zero market risk and high execution risk.
Saam frames every Greylock initiation as picking shapes like Workday (cloud HRIS replatform, demand obvious), Palo Alto Networks (10+ firewall companies, demand obvious), Abnormal AI ($2B email security TAM, 2 incumbents, demand obvious). The only question was 'can this team build the machine.'
Stop searching for unknown markets; back the best team to win a market that obviously exists.
“what we wanna do is pick opportunities where there''s zero market risk and actually a lot of execution risk because in the execution risk you build, your remote products are hard to build”Saam Motamedi
Principle
Best supporting actor — venture is a service job, not a star vehicle
A venture firm's core ethos must be that no partner is ever larger than the companies and founders they back.
Greylock's founding partners encoded this as the operating constitution: minimal press, minimal marketing, partners never positioned as stars. Saam frames it as deciding where on a 1-10 spectrum from invisible to marketing-machine you live — and you can never be a 10 without compromising the ethos.
If your venture brand is louder than your portfolio, you've already started to decay.
“the ambition of every Greylock partner should be to win the Oscar for the best supporting actor to the entrepreneur”Saam Motamedi
Principle
Successful brands decay via refusal to reinvent
Default trajectory of a successful franchise is decay, driven by unwillingness to reinvent operations every era.
Saam cites Greylock''s recent moves: HQ to SF, younger team, multiple partner meetings per week — strategy unchanged in 20 years, operations radically changed.
If your firm operates as it did 5 years ago, you''re probably decaying.
“there''s this weird empirical thing that happens when people become successful. They are not willing to reinvent themselves... the default trend line is one of decay”Saam Motamedi
