 A tiny angel fund for the agent era · Founded 2024

Last Node backs the builders behind AI-native software.

Last Node is a tiny angel fund. We write early checks to founders creating AI-native tools where the agent does the real work, and we stay close, as people who have shipped the same class of product ourselves.

HOW WE INVEST
Small checks, real conviction.

§ 01 · thesis

The agent era will reshape who gets to start a software company.

For two decades, the unit of leverage in software was a large team. That is changing. A capable model and a few people who know precisely where to point it can now close entire workflows: billing inboxes, deliverability, go-to-market motion, customer support. Work that once required a whole organization.

Last Node exists to back the founders seizing that shift. We commit only where AI is load-bearing: remove it and the product no longer functions. We fund durable software for real operational work, not demos, not wrappers.

Load-bearing
If removing the AI breaks the product, it qualifies. If not, we pass.
Operator-led
Led by founders who have run the workflow they are now automating.
Focused
A single, well-defined wedge beats a broad platform on day one.
Compounding
Products that improve with every use by the same customer.

§ 03 · investment focus

We write small, early checks to opinionated founders creating tools we would use ourselves.

fig. 02 · a platform decomposes into agents.
I.

Stage

Pre-seed and seed. First or second money in. We are comfortable as the smallest check on a strong cap table.

II.

Check size

$25k to $250k from the fund. We do not lead. We decide quickly and communicate clearly.

III.

What we look for

AI-native software where the agent does measurable work, led by founders who have lived the problem firsthand.

IV.

How we help

A partner who has been in your seat, introductions across our portfolio, and a clear answer within a week, including a no.
