StackOne is the universal integration layer for modern SaaS products. We’ve raised $24m in 2 years, and we’re backed by top-tier investors like Google Ventures and Workday Ventures.
Our unified API platform lets vendors ship hundreds of native, white-label integrations in days, not months, by abstracting away dozens of disparate third-party APIs into a single, normalized interface. On top of those APIs, we provide AI Agent Actions so customers can build agentic workflows without wrangling OpenAPI specs.
StackOne sits behind the scenes as an embedded iPaaS: SOC 2 compliant, multi-tenant, and invisible to end users, powering integrations for future-of-work SaaS categories such as HR, Compliance, and AI Agents.
Our customers are established B2B SaaS companies that:
Sell to mid-market and enterprise buyers
Are building AI Agents in the near future
Need deep, native integrations to win competitive deals and power their product
Value time to integration over building connectors in-house
We typically close OEM and embedded licensing deals, multi-year (1 to 3 year) contracts, five to seven figure TCV, with a strong land and expand model. Key buyer personas are the CPO and CTO.
We’ve achieved breakout growth in 2024 and are now evolving our go-to-market strategy—with product marketing as a cornerstone. You’ll shape how we position, package, and bring our platform to market across key buyer personas and verticals.
This role requires balancing strategic thinking with tactical execution. You’ll operate as a player-coach, responsible for messaging, positioning, sales enablement, competitive insights, and product launches—while also rolling up your sleeves to deliver materials and campaigns yourself.
StackOne sits at the intersection of product, engineering, and GTM. Our buyers are technical (CTOs, Heads of Product), and our value prop is deep. Your job is to translate complexity into clarity—to help prospects and customers understand not just what we do, but why it matters now.
