These slots are intentionally open — we decide on people and idea before we decide on grid. If you're unsure whether you fit: just submit.

How we work

Four steps. No loops.

  1. 01

    You submit.

    Form or a short pitch by email. Deck welcome, no required format.

  2. 02

    We respond.

    Within a few days — with a real answer, not a templated rejection.

  3. 03

    First conversation.

    30–45 minutes. You show what you're building. We listen and ask honest questions.

  4. 04

    Deep dive & term sheet.

    If both sides want to keep going: structured process, clear term sheet, no drama.

What you get from us

More than capital. Less than theatre.

Capital from substance.

We invest off our own balance sheet — no fund vintage, no exit clock, no fundraising hat.

Operator mindset.

We come from building. That means concrete sparring partners, not deck coaching.

A network that helps.

Access to mid-market, operating talent and long-term co-investors — when you want it.

We follow on.

Founders who start with us grow with us — they don't end up alone after 18 months.

FAQ

Before you ask.

Do you invest at pre-seed?
Yes — if we understand the founders and the thesis. An MVP isn't required; clarity of conviction is.
How fast do you reply?
Usually within [X] business days. Even a no comes quickly and with a real reason.
Do you need an NDA?
Not in the first round. We treat everything as confidential — that's professional ethic, not paperwork.
What if it's not a fit?
We say so clearly — and refer you onward when we can.
Lead or co-invest?
Both work. We don't force a role that doesn't fit the round.
What do you expect from us?
Honesty, clear communication, long-term thinking. We don't need hockey sticks — we need substance.
