We invest where software
meets the physical world

01

Infrastructure Software

The tools that power every other company. Developer platforms, data infrastructure, and cloud-native systems that become the default.

02

Applied AI

AI-native products that solve specific, measurable problems — not demos. Companies where AI is the product, not a feature bolted on.

03

Climate & Energy

Software and hardware at the intersection of decarbonization. Grid optimization, carbon accounting, and next-gen energy systems.

How we work with founders

We write the first check and stay through every round. Our model is simple: few bets, high conviction, deep support.

01

Initial Check: $500K – $3M

We lead or co-lead pre-seed and seed rounds. No party rounds. We want to matter on your cap table and in your boardroom.

02

Follow-On Reserves

We reserve 2x our initial investment for follow-ons. When you're winning, we double down. 85% of our portfolio receives follow-on capital.

03

Operational Support

Recruiting, GTM strategy, technical architecture review. We do the work — not hand you a Notion template and call it "platform."

04

72-Hour Decision

After a partner meeting, you'll have our answer within 72 hours. We respect founders' time because we've been founders.
