What the job involves
- We’re looking for a Product Manager – Consumer AI to own our consumer-facing products:
- Disco: a consumer-friendly hub for discovering and using AI tools via the MCP ecosystem
- StackChat: our LLM client with citations, evolving into agentic execution
- You’ll lead a highly focused squad of 2-3 engineers to build the best consumer tool layer and the best LLM client, with a strong product-led growth (PLG) mandate. You’ll work directly with the founders and have high ownership in shaping vision, distribution, and execution
- Define product vision, roadmap, and success metrics for Disco and StackChat
- Drive PLG loops across activation, retention, referral, and monetization
- Run weekly experiments and rapidly iterate on consumer AI use cases
- Lead product marketing: positioning, launches, website copy, demos, templates
- Build distribution channels: integrations directory, presets, shareable agents, SEO

Salary benchmarks
Our take
The explosion of SaaS tools has created an integration nightmare for companies. More and more B2B customers are expecting their SaaS tools to integrate with each other natively. But building and managing API connections in-house as a software vendor is time-consuming and costly, diverting teams from their core roadmap and stopping sales teams from selling.
As the next-generation integration platform, StackOne is solving the challenge of building SaaS integrations at scale once and for all. Founded in 2023 by ex-Google and Oracle executives, StackOne has seen exceptionally fast growth since its launch. With its best-in-class security and real-time architecture, the company is well-positioned to become a category leader in the API integration solutions market.
