GRAYBOOK VENTURES

Approach

One partner from the first commit to the strategic round.

Most investors bring capital. We bring capital and a trading group: a platform to build on, infrastructure to run on and traders to sell to. The further a company grows, the more of it we can put to work.

The four stages in detail.

Check sizes are a guide, not a rule. We size to the company and the round.

01

Pre-seed & Seed

Build on Graybook

Founders building trading tools, analytics and strategy products on the Graybook platform, its Script Editor, GBS and Vig.

Typical check [$100K–$500K]

  • Capital
  • Platform access
02

Series A

Prove it in production

Execution, market-data, risk and compliance software that has to run against real order flow before it can sell.

Typical check [$500K–$2M]

  • Capital
  • Platform access
  • Infrastructure
03

Growth

Scale with the network

Prop firms, brokers and trading venues growing on Graybook technology, and the vendors that serve them.

Typical check [$2M–$10M]

  • Capital
  • Platform access
  • Infrastructure
  • Distribution
04

Strategic

Partner for the long run

Established firms where a minority stake and a commercial partnership with the Graybook group make both sides stronger.

Typical check [Case by case]

  • Capital
  • Platform access
  • Infrastructure
  • Distribution
  • Partnership

What we bring

More than a check.

Every portfolio company gets the Graybook group behind it: the platform, the infrastructure and the traders.

  1. 01

    Capital

    Lead or co-lead checks from pre-seed to growth, with reserves to follow on when the business is working.

  2. 02

    The Graybook platform

    Early access to the trading terminal, the Script Editor, GBS and Vig, our AI quant, plus a direct line to the engineers who build them.

  3. 03

    Infrastructure

    Quant VPS and colocation from Graybook Technologies, so a portfolio company can trade beside the exchange from its first day.

  4. 04

    Distribution

    A route to the traders on Graybook Proprietary Trading, for products that make trading safer, faster or better informed.

How we invest →

How we invest.

Four steps, a partner at each one, and a clear answer at the end.

  1. 1

    Intro

    Send a deck or a one-pager. A partner reads every submission and replies within [5] business days.

  2. 2

    First call

    30 minutes on the product, the market and how Graybook could help, before any numbers.

  3. 3

    Platform fit

    Our engineers look at how you would build on or plug into Graybook. You meet the people you would work with.

  4. 4

    Decision

    Diligence, a term sheet and a yes or no within [4–6] weeks of the first call.

Questions founders ask us.

Something else? Ask a partner.

Do we have to build on Graybook to raise from you?

No. We back firms that use our technology and firms that improve trading technology more broadly. Using Graybook helps us help you, but it is not a condition.

Do you lead rounds?

We lead or co-lead at pre-seed and seed and usually join rounds led by others from Series A onward. [Confirm with partners.]

Will you share our information with the other Graybook companies?

Not without your written permission. Pitch materials stay with the Ventures team, and any introduction to Graybook Proprietary Trading or Graybook Technologies happens only when you ask for it.

Do you invest outside North America?

[Yes, where the market structure and the team fit. Most of our early investments are in the US and Canada.]

What don’t you invest in?

Signal-selling, copy-trading schemes, guaranteed-return products and anything we wouldn’t want our own traders to use.

Think you fit somewhere on the curve?

Tell us where you are and what you’re building.
