TFJS The Fencing & Jousting Society
Hold a key?

No applications Est. behind the yellow door · Moscow, 2011

By invitation only. Or know someone who knows someone.

Alumni of the door, and the ones who made the crossing first and stayed on to belay. A small society that does the unglamorous part of venture together - the diligence, the introductions, the 2am calls - and celebrates properly afterwards. If you were sent here, you hold a key.

The code.

Five tenets. We mean them. A fencing salle runs on the same principle: the rules are few, the salute is not optional, and nobody hits an opponent whose mask is off.

I
Mentor the next ones.
Someone once gave you an evening on the piste, for no glory whatsoever. That debt is paid forward, never back - and the lender also comes away the sharper.
II
Tell the real story.
Not the keynote version. The near-death, the bad term sheet, the parry that actually worked.
III
Be a badass.
Show up sharp. Move fast, under the radar. Earn the room you walk into (you wouldn’t be here if you hadn’t). Then hold the door for the next one.
IV
Guard the door.
The society stays small on purpose. You vouch for who you bring through it, and you answer for them.
V
Work hard. Play hard. Be kind.
Nice is free (and worth about that). Kind costs something - your attention - and that is the one we mean.

A society, in the old sense - the kind with a password and a bar.

A KYC'd, invite-only community of founders & investors - alumni of The Yellow Door - connecting tech-rich but hard-to-reach markets with global ones. We build value & trust before any money moves, invest money & time together, then support & scale what we back. There is no general partner upstairs: every member votes on every deal, or politely abstains. Members earn the old-fashioned way: deal-lead carry and standardised advisor equity. Value flows to those who create it.

Before · the salle
Value first, money later.

Founders come to fence. We test, refine, run the drills and break things politely - for months before a single cheque is written. This is the fencing. And the jousting.

During · the tilt
Money & time, together.

Rounds combine capital with mentoring, community services & support. Members invest funds, skills or hours - time earns equity too.

After · the toast
Success compounds.

Deal leads earn carry, advisors earn standardised equity, and the society's own share pays for the next generation's lessons. Then someone presses the button.

§ The four layers

How the society is built.

A venture operating platform - network on top, capital at the bottom, intelligence throughout.

01
Elite network - F&JS
The invite-only inner circle: investors, experienced founders, domain experts, operators & mentors.
02
Broader community - The Yellow Door · Labs
The public face & structured intake: events, intensives, education, inspiration, reputation points.
03
Platform + AI intelligence
Discovery, referral, evaluation & portfolio support; AI agents compile each startup's living Deal Memo, which becomes its Operating Plan after funding.
04
Embedded fund → the I8GV Main Fund
A small members' fund, paced by fund math rather than enthusiasm. Follow-ons & formal syndication through the Main Fund.
№ 1
Everyone plays every position
Members are founders, builders, mentors, specialists & investors - at once or in turn.
№ 2
Vetted at the door
Entry through Yellow Door programming, or a member's vouch. Deep expertise & achievements - not theory.
№ 3
Wide, early, continuous
Member referrals + unique markets = companies discovered 6-12 months ahead of the competition, de-risked continually.
№ 4
Discreet outside, KYC inside
Full internal KYC to global best practice; to the outside world members are discreet - never anonymous. Value flows to those who create it.
§ Why fencing. Why jousting.

Where the Brothers Durov kept their fencing club.

In 2011 we opened one of Moscow's first co-working spaces for founders, in the building where the Durov brothers once ran their salle. A tight group of mentors - world-class operators, every one - started testing and refining startups there. For nothing. For years. Founders came to be run through, politely, so the market wouldn't do it first. Hence the name. The Yellow Door became legend; the mentors became the Society.

“May the tradition of building the people of the future - strong and agile - live on.”
- the founding note, 2011
Fiercely independent Non-profit Authentic Effective
§ From the archive

Four ways in. Nobody needs introducing twice.

A company can start with any of the four and go on through all of them. Each passes it to the next under contract, not as a favour. (We've watched the favour version. It doesn't scale.)

It follows on where the first three have already made the case.

Since 2012, Startup Embassy in Palo Alto has hosted founders from ~90 countries whose companies include Konfio, Matternet, Labelbox, Aragon and Mashgin - hosted at idea stage, before our investment model existed.

● The app stays behind the password

Public philosophy. Private machinery.

Everything above is yours to read; we're not precious about it. The interface where the Society actually lives - deal memos, portfolio dashboards, the secondary board, the rooms - is behind the password. Naturally.

§ Who's in the room

You'll know some of the faces. You won't be told all of them.

Founders who've exited, partners at funds you've heard of, and an operator or two who'd rather not be named. You can't buy your way in. Someone holds the door for you, or they don't.

§ The ritual

Every evening ends the same way.

At some point, someone remembers the champagne. The fun gets serious. (No deck has ever captured this. We've tried.)

● Entry · by password

There is a secret password.

You don't find the Society; it finds you. If you have the key, you know what to do - and if you have to ask, not yet.

● Entry · by introduction

No word? Then a name.

If someone sent you without the password, tell us who. We'll set up half an hour on Zoom with a few of us - and the person who recommended you comes too. (It's their reputation as much as yours.)

The dispatch
A letter, occasionally.

Cohort openings, party invitations, the odd confession. Once a fortnight at most, and never boring - we'd be too embarrassed.
