§ STACK VENTURES
Investing in the builders of the AI-native stack.
Stack Ventures backs early- and growth-stage companies building the tools, marketplaces, and infrastructure that define how software gets bought, built, and run in an AI-native world.
§00 — WHY WE INVEST
Backing the ecosystem we build alongside.
Stack18 exists to take a business from plain-language intent to production software, governed at every step. Stack Ventures exists to back the founders solving the problems around that same shift — how technology gets discovered, evaluated, procured, and operated once AI agents are doing real work inside it. We invest in companies that share that view of where software is headed, and back them early enough that our support actually moves the needle.
§01 — WHAT PORTFOLIO COMPANIES GET
More than a check.
Direct access to the Stack18 pipeline
Portfolio companies can run their own roadmap through the same governed, nine-agent pipeline that powers Stack18 Enterprise — shipping faster without building out a full engineering org first.
Support from people who've run the engagements
Our team has scoped, staffed, and delivered real Enterprise engagements. That operating experience is available to portfolio founders directly — not filtered through a platform.
Introductions to our enterprise customer network
Where there’s a genuine fit, portfolio companies get warm introductions into the Stack18 Enterprise customer base — real buyers, not a logo wall.
§02 — OUR INVESTMENT FOCUS
What we look for.
A view of software we recognize
Founders building for a world where AI agents do real, governed work — discovering, evaluating, building, or operating software — not just wrapping a chat interface around an existing product.
Early- to growth-stage, alongside a lead
We typically invest at seed through Series A, in partnership with a lead investor — check size and involvement scoped to what actually helps at that stage.
Builders who take traceability seriously
We back teams that treat auditability, transparency, and human oversight as a feature of good AI systems, not friction to design around — the same conviction the Stack18 pipeline is built on.
§03 — OUR INVESTMENT PORTFOLIO
