About the RoleA YC-backed, seed-stage AI developer infrastructure startup in San Francisco is looking for a
GTM Lead to own the entire go-to-market function from day one. The company builds sandboxing and testing infrastructure for AI agents - a nascent, fast-moving space that has already hit product-market fit ahead of schedule, with demand outpacing supply.
You'll be the first dedicated GTM hire at a tight-knit four-person team, working directly with the founders to build marketing, tune the sales pipeline, and run the GTM operations that prove what's working. This is a
hands-on execution role - you do the work yourself before you build a team. Visa sponsorship is not available for this position.
What You'll Do- Own marketing end-to-end: positioning, messaging, content, launches, and demand generation.
- Co-own story and brand direction with the founding team, then execute the strategy and iterate based on results.
- Tune the sales pipeline by analyzing how leads arrive, get qualified, and where they stall - then fix the bottlenecks.
- Run constant experiments and let data, not opinions, drive what you double down on.
- Reach a technical audience authentically - engineers and platform teams who reject marketing speak.
- Handle GTM ops: tooling, tracking, and reporting that surface what's actually working.
- Write copy, build sequences, and read the numbers yourself until the motion is proven.
- Hire and lead marketers once you've validated the playbook.
What We're Looking ForMust-haves:- 3+ years of hands-on B2B growth marketing experience, with direct involvement in taking a company from Series A through Series B - in the room making decisions, not adjacent to them.
- Deep technical fluency: you can explain complex infrastructure or developer tooling concepts to engineers without a translator.
- Proven ability to build and execute an end-to-end B2B marketing function (positioning, messaging, content, demand gen, pipeline tuning) independently.
- Demonstrated track record of running A/B tests and experiments at volume, with data-driven decision-making to match.
- Experience marketing to technical audiences - engineers, platform teams, infrastructure buyers - without falling back on marketing clichés.
- Hands-on GTM ops experience: pipeline tracking, analytics, reporting infrastructure.
- Experience optimizing sales pipelines including lead qualification, bottleneck identification, and conversion improvement.
Strong pluses:- Background in developer tools, infrastructure, or platform companies.
- Published technical writing under your own name - newsletter, Substack, blog, or documentation with a real audience.
- Experience leading a company through a repositioning or rebrand and measuring its impact on metrics.
- Prior experience hiring and managing marketing team members.
Compensation & Benefits- Base salary: $180,000+ USD annually (commensurate with experience)
- Early-stage equity in a well-funded, high-traction company (Seed stage, backed by top-tier investors)
LocationThis role is
on-site in San Francisco, CA. Candidates must be based in San Francisco or willing to relocate. Remote or hybrid arrangements are not available for this position.
