experiments are good.
Lean Lightbulb is a venture studio. We build, test and launch alongside founders across media, games, AI, fintech, climate, web3 and art, and help the best of them get ready to raise.
MVPs and films built and launched
From games to green energy
Before launch. Always.
Build fast. Learn faster.
Most ideas fail because nobody tested them. We help founders prove what works, quickly and cheaply, before betting big.
MVPs, fast
From idea to working product in weeks. Lean, testable, and in front of real users early.
Proof, not hope
We run the experiments that tell you what to keep, what to kill, and what to double down on.
Ready to raise
Pitch, story and numbers shaped so founders walk into investor meetings prepared.
Eight places we experiment.
Media
Film, video and new formats for telling stories.
Games
Indie studios, playable worlds and interactive IP.
AI
Tools and products built AI-first.
Fintech
Simpler, fairer ways to move and manage money.
Climate
Energy, solar and practical planet tech.
Web3
On-chain ownership, communities and digital assets.
Art
Generative, digital and physical work.
Tech
Software and platforms that solve real problems.
Experiments we're running now.

A one-year experiment: 30-second video messages from anyone, to the whole world, numbered and played globally.

We work with founders across all eight of our sectors, and we actively seek out women and Black, Asian and ethnic minority founders, who are too often missed by mainstream networks. Talent is everywhere. Access isn't.
