We invest in hard tech and hard sectors.
☢️ Nuclear reactors
🫀 Organoids and improved IVF
🪚 Next gen sawmills
✈️ Drone swarms
🦾 Surgical robots
🔋 Industrial scale batteries
We’ve backed all of these, and plenty more companies that don’t fit into neat categories.
We’re hyper curious; drawn to difficult, underexplored areas; and always up for a deep dive.
Unlocking society’s potential depends on founders willing to build what others won’t.
If you’re building something that others can’t, we want to work with you.
While you build, we back you with:
- More capital for this round. For every $1 we invest, we help bring in $2-$3 more on average from other great investors.
- More firepower for the next round. 60% seed-to-Series-A graduation rate vs. 15% industry average.
- Strategic and tactical playbooks. Lessons from 150+ companies and 10+ unicorns over 12+ years.
- Storytelling, customer intros, expert intros, and startup-friendly perks and discounts that move the needle.
