For operators who want an advisory, fractional, or creator future rather than another full-time role, Fareed prescribes deliberately building 'specific knowledge' — a topic narrow enough that you can credibly claim to be one of the five best in the world at it — paired with enough breadth to connect dots, and a resume of recognizable companies. That intersection is what companies too early to hire that person full-time will pay for, and what makes you sellable when the sales-and-BD reality of advising kicks in.
Origin
Fareed Mosavat's synthesis, tying back to Naval Ravikant's 'specific knowledge' concept; observed across Reforge's executive network.
Core principles
- 01Value comes from specific knowledge narrow enough to be near-best-in-world, not from being a generalist 'expert at company.'
- 02You need depth plus enough breadth to connect data points across problem types and industries.
- 03Where you worked is a real part of the sellability equation — recognizable names reduce the selling you must do.
- 04Advising is a portfolio bet on upside and flexibility, but carries constant sales/BD and no employment safety net.
How to run it
- 1
Build a narrow, near-best-in-world specialty
Take enough reps in a focused area (e.g. bottoms-up SaaS activation, zero-to-one paid channels) that you can credibly say you're one of the five best in the world at it and accelerate someone's learning dramatically in an hour.
Pro tip Pick an intersection specific enough that a company can't easily hire that exact person full-time because they're too early or under-resourced.

Add breadth by varying one axis at a time
Collect diverse data points: same problem in a different industry (depth-focused), or different problems in the same industry (breadth-focused). Don't stay so narrow that only one company type fits you.
Pro tip Deliberately choose opportunities that balance depth and breadth so you can connect dots across contexts.
Watch out Being too narrow — e.g. only D2C e-commerce with once-a-year purchases — limits the range of companies you can help.

Work at recognizable places
Choose employers that are 'fundamentally working,' because a rising tide creates real opportunities for deep impact, and known names make you far easier to sell later.
Pro tip You won't have to spend time explaining what Slack or Airbnb is — the brand does part of the selling for you.
Watch out You will inevitably have to sell yourself as an advisor; unknown employers make that harder.

Weigh the downsides before committing
Accept that this path means no health insurance, no PTO, no 401k match, unclear longevity as you drift from full-time experience, and constant BD to line up the next client.
Pro tip Consider a hybrid — an anchor full-time focus plus casual advising, angel investing, and mentorship — if you dislike selling.
Watch out If everyone does it, the uniqueness erodes; and the perpetual sales requirement is why many operators find it unattractive.
In the wild
Fareed says he feels like a genuine expert in bottoms-up SaaS activation strategies — narrow enough that if someone has a problem in that space he can usually accelerate their learning dramatically in an hour.
→ That specific, hard-to-replace knowledge is the kind that lets an operator make a meaningful living advising across many companies rather than working full-time at one.
Common mistakes
Claiming to be an expert at 'company' generally
No one is genuinely expert across all of company-building; sellable value lives in a narrow sub-expertise where you can credibly claim top-tier standing.
Ignoring the sales, safety-net, and longevity costs
Romanticizing the advisory life overlooks the constant BD, absent benefits, and the open question of how long you stay valuable once removed from full-time operating.
Is it for you?
Best for
Senior operators with meaningful company experience considering fractional, advisory, or creator work.
Not ideal for
Early-career PMs who haven't yet built deep specific knowledge or a recognizable track record, or people who need employment stability and benefits.
From the transcript
“what is my specific knowledge just to tie the knots back to the thing we started at the beginning that because I've taken so many…”
“just narrow enough that I know I'm I'm one of the five best in the world”
“same problem different industry is one way to think about depth that's focused different problems same industry is another way”
“it's a lot easier to sell experience of places people have heard of than places nobody's heard of”
