How we show up

Three promises to every founder.

  1. 01

    Do the work.

    Advice is cheap. We build plans, make intros and hire alongside you.

  2. 02

    Say it straight.

    Bad news early. Good news often. No surprises at the board meeting.

  3. 03

    Play the long game.

    We back companies that will matter in ten years, not ten months.
