EarlyWork Ventures — Sydney

Backing founders before it’s obvious.

Angel investment and early-stage counsel for technical founders in Australia and New Zealand — often before a raise is on the table.

Who I work with

Reach out if you’re…

A fit

  • Building something technical or scientifically grounded, in ANZ or with ANZ ties.
  • Pre-seed or seed — or earlier. Pre-deck conversations are preferred.
  • Willing to have your assumptions tested, not just validated.
  • Comfortable with honest, unvarnished feedback.

Not a fit

  • Later-stage rounds or growth capital.
  • Generalist consumer plays without a technical edge.
  • Pitches built on momentum rather than evidence.
  • Founders looking for a quick “yes” rather than a useful conversation.

If you’re unsure — write anyway. A short note on the problem you’re working on is the best place to start.

How I invest

Three ideas that shape every decision.

01

Falsifiable assumptions.

Every thesis is a set of claims that can be tested. I spend more time trying to break them than confirm them.

02

Execution over mythology.

Startup folklore is cheap. Founder capability and domain insight are not. I weight the second far more than the first.

03

Outcome pre-filter.

Before deep diligence, a simple question: is the realistic outcome shape worth anyone’s time? If not, we both save it.

Focus Areas

Sector-agnostic, with repeated pull toward a few places.

Technical innovation keeps opening new possibility spaces. These are the ones I keep returning to.

AI infrastructure tooling, orchestration, and compute for AI-native products.
Developer tools software that makes builders faster and more creative.
Climate & energy hard engineering for decarbonisation and resilience.
Bio & health tech computation applied to discovery, diagnostics, precision care.
Security & trust infrastructure that keeps data and identity safe at scale.
Future of work platforms reshaping how people collaborate and create value.
About

John Keith.

Sydney-based angel investor. I back early-stage founders across ANZ from personal capital — not a fund.

Day job: Managing Director at BNP Paribas, working in capital markets, regulatory, and structured finance. Former Chair of Atomo Diagnostics (ASX:AT1), which I saw from kitchen table to public listing. That experience — capital markets, governance, regulatory scar tissue — is what I bring to the companies I back.

I mentor at StartMate, explore at AirTree, and teach as a Practice Coordinator/Mentor at the University of Sydney Business School, working with MBA, EMBA, and Genesis accelerator founders.

A short note on the problem you’re solving beats a polished deck every time.
