Founding Growth

Karumi is building an AI agent that joins video calls and delivers live, interactive product demos autonomously — answering questions, navigating the product in a real browser, and booking follow-ups, 24/7 and in any language. We're a Y Combinator company with real traction (thousands of demos delivered and a growing book of paying B2B SaaS customers) and we're now hiring our founding go-to-market team.

As our Founding Growth hire, you'll own how Karumi reaches its market. You'll build the demand-generation engine from scratch — across content, paid, lifecycle, and our own AI agent as a top-of-funnel growth loop — and turn it into a repeatable source of pipeline.

What you'll do

• Build and own the growth engine: demand gen, content/SEO, paid acquisition, and lifecycle.
• Design and run experiments to drive qualified inbound and improve conversion across the funnel.
• Use Karumi's own demo agent as a growth channel and a flagship example of the product.
• Own the analytics: define metrics, instrument the funnel, and report on what's working.
• Partner with the founders and the AE on messaging, positioning, and pipeline targets.

Who you are

• 5+ years in growth, or a founding/early growth hire at a Series A/B startup.
• A full-stack marketer — you run content, paid, SEO, and lifecycle yourself, not just brief a team.
• You've actually scaled revenue and growth before, and can point to the numbers.
• Strongly analytical; you instrument, measure, and iterate rather than guess.
• Excited about AI and a genuinely novel product category.

Your First 90 Days

• By day 30: you'll have audited our funnel, picked the first growth channels to bet on, and launched your first experiments.
• By day 60: you'll have a repeatable inbound motion running, with metrics instrumented end to end and early wins to point to.
• By day 90: you'll have turned Karumi's own demo agent into a working top-of-funnel growth loop and defined the playbook for scaling it.

Why Karumi

• Founding seat on the GTM team at a YC-backed, revenue-generating AI company.
• Build the growth function — and the team — from zero.
• $140–180K plus meaningful founding-level equity. Based in New York, in office.

The Team Karumi was founded by Pablo Omeñaca and Toni López, who previously built StackAI together — Pablo as founding engineer and then COO leading customer implementations, and Toni as an early engineer building its agentic systems. They helped grow StackAI from early revenue to roughly $10M ARR.
