A non-scalable talent-development method that scales your product judgment through an organization. First run product work as a 'teaching hospital' — pull as many people as possible into the room while you make decisions so your passion and approach spread. Then grab someone from the ranks as your tech assistant to shadow you for six to twelve months, absorbing everything, until they become a 'mini-me' you can place in a much bigger role.
Origin
Mark Pincus's approach to 'transferring vampire blood' — spreading a founder's burning mission and product instincts. He notes it scales: Andy Jassy and much of Amazon's S-team had been technical assistants to Jeff Bezos.
Core principles
- 01Great management uses non-scalable methods that actually scale your product judgment
- 02Run product work as a teaching hospital: do it in the open with many observers in the room
- 03Your passion and approach spread by proximity, not by documents
- 04A tech assistant who shadows you long enough becomes a placeable 'mini-me'
- 05The best shadow is your younger self — the expert witness who's a bit of a know-it-all
How to run it
- 1
Run product meetings as a teaching hospital
Put as many people as you can in the room while you do the actual product-management work. Let them watch you make real decisions so your instincts, passion, and approach spread to all of them at once.
Pro tip Treat every real decision meeting as a training opportunity, not a closed session.
- 2
Recruit a tech assistant from the ranks
Pick someone who reminds you of yourself in your 20s — an expert-witness type, a little bit of a know-it-all — and make them your technical assistant to follow you everywhere.
Pro tip Choose for hunger and rightness over polish; you want the pent-up drive to prove themselves.
- 3
Have them shadow for 6-12 months
Let the assistant follow you for six months to a year, absorbing everything you do. Give them projects to test what they've picked up and to reveal where they still have gaps.
Pro tip Use the test projects to calibrate readiness before you place them.

Place the mini-me in a bigger role
Once the assistant has internalized your approach, drop them into a much larger role elsewhere in the org. This propagates your product instincts across the company and scales 'for free.'
Pro tip Institutionalize it — Amazon's S-team was seeded with former Bezos technical assistants.
In the wild
Pincus packed people into his product-management meetings so his passion and approach would spread, then took individuals from the ranks as tech assistants who shadowed him for six to twelve months before being placed in bigger roles.
→ He created 'mini-mes' who carried his product instincts into larger roles across the organization.
Pincus cites that everyone on Amazon's S-team used to be someone who had served as Jeff Bezos's technical assistant, shadowing him closely.
→ The shadow-and-place model scaled Bezos's judgment across Amazon's most senior leadership 'for free.'
Common mistakes
Making key product decisions behind closed doors
If you do your best product thinking privately, no one absorbs how you decide. The teaching-hospital method only works because people are in the room watching real decisions — closed sessions waste the chance to transfer your instincts to many people at once.
Expecting instincts to transfer via documents
Product judgment ('vampire blood') is tacit and spreads by proximity and shadowing, not by written process. Skipping the 6-12 month apprenticeship and hoping a memo conveys your approach produces people who follow rules but lack the underlying instincts.
Is it for you?
Best for
Founders who want to clone their product judgment across a scaling org without diluting it
Not ideal for
Very small teams or short-lived projects where there's no time horizon for a 6-12 month apprenticeship to pay off
