B4 · A private community of investors

Invest
Before
Market.

B4 — because "before". We back founders while the market is still asking what they do. A closed circle of funds, angels and operators who move earlier than everyone else — and keep quiet about it.

01 / THESIS

What we get into

The best entry point is the one nobody is watching yet.

Every member of B4 invests before market — before the round is hot, before the metrics chart is up and to the right, before the name is on anyone's list. Our funds and angels share dealflow, diligence and conviction inside a closed circle. What happens after entry, the market finds out on its own time.

The list is a direction, not a fence. If it's early, technical and uncomfortable to explain at a dinner party — it's probably ours.

02 / THE FUNDS

Three funds.
The rest stay inside.

B4 unites several funds under one roof. Out of respect for the circle, we show only three. Membership of the rest is disclosed to members only.

Representative in B4
Represents
Point Nine.
Berlin · Europe

A thesis-driven early-stage firm run by four equal partners, writing $1–10M first cheques into software long before it's obvious — early money behind Revolut, Loom and Docplanner.

Mirae.미래
Seoul · Korea

Mirae means "future" in Korean — which is roughly where the fund prefers to invest. It anchors B4's Web3 and crypto practice, backing protocols and on-chain products long before listings, narratives or noise.

Forerunner.
San Francisco · US

An early-stage firm backing founders who define entire categories — Chime, Glossier, Warby Parker, Oura and Faire were all Forerunner entries before the market caught on.

Focus — Consumer · Brands · AI platforms
Additional member funds are not listed publicly. That's the point.
03 / CASES

Ours, early.

Nine projects that grew up with this circle behind them. No scoreboards, no victory laps — just the work, backed before the market arrived.

Cursor
AI · DevTools

The AI code editor that changed how software gets written. What started as a strange idea — an editor that writes with you — is now the tool half the industry opens every morning. This circle was there while it was still strange.

Hyperliquid
Web3 · Trading

A decentralized exchange for perpetuals, built the hard way — on its own chain, by a team that refused shortcuts. Today it's where on-chain traders actually trade. We believed back when “another DEX” was a punchline.

Fire
Web3 · Sustainability

Blockchain for sustainable development, built with partners in Korea. Fire puts real environmental work on-chain — transparent and verifiable — proof that crypto can build something that outlives a market cycle.

Meendo
AI · Privacy

Private meeting intelligence. Meendo listens, writes the notes, assigns the tasks — and encrypts everything end-to-end, so what's said in the room stays in the room. A product this community understood instantly. We run on the same principle.

Sui
Web3 · Infrastructure

An L1 blockchain and smart-contract platform engineered for scale from day one, on an object model most chains still don't understand. Base-layer infrastructure for whatever comes next.

Jasper
AI · Marketing

The AI copilot for marketing teams — writing, campaigns and brand voice, back before generative AI was on anyone's roadmap slide. One of the first proofs that AI could be a business, not a demo.

Waaako
SaaS · Productivity

One workspace instead of a dozen tools: planning boards, funnels, analytics, docs and team stats under one roof. The kind of unglamorous, useful software this community loves before anyone else does.

Amenitiz
SaaS · Hospitality

The operating system for independent hotels and B&Bs — property management, channel manager, booking engine, website and payments in one place. Software for people who were never anyone's priority. That's exactly why it works.

Uranium Digital
Commodities · On-chain

The first crypto-powered spot market for uranium. A market that barely existed in digital form, rebuilt from scratch on-chain. The strangest idea on this page — and the most obvious once you've heard it.

Who backed what stays inside the circle. That the backing came early — doesn't.

04 / COMMUNITY TEAM

The people running B4

A community that moves before the market needs eyes everywhere and noise nowhere. This is the crew that keeps it running.

Min-ji Kang

Min-ji Kang

Head of Research

Leads the analyst desk. Turns raw dealflow into memos members actually read — short, sharp, and early.

Layla Haddad

Layla Haddad

Analyst · Web3 & DeFi

Reads whitepapers so members don't have to. Covers on-chain markets, token design and everything Mirae drags in.

Tomas Eriksen

Tomas Eriksen

Community Manager

Keeps the inside quiet and the outside curious. Runs member ops — and yes, he's the one behind the Twitter.

Jamal Carter

Jamal Carter

Scout

His job is to hear about a company before it has a website. If a deal reaches your feed, Jamal saw it months ago.

Amir N.

Amir N.

Dealflow & Ops

The pipeline lives in his head (and one very protected database). Routes deals to the right funds, quietly.

05 / APPLICATION

Three questions.
That's it.

If you invest before market — or want to learn to — this is the door.

Applications are reviewed by the team, not a form bot
We reply only if it's a fit — silence is an answer too
Everything you send stays inside the circle

Application received.

Thank you. The team reviews every application personally. If it's a fit, we'll reach out through the contact you left. Until then — keep investing before.
