Growth

Karumi lets SaaS companies deliver personalized product demos at scale, 24/7, in any language. Our AI agent learns from any software product, joins video calls with prospects, and navigates the product in a real browser while talking, listening, and taking actions. By delivering the “aha moment” instantly, Karumi eliminates demo waiting times and boosts conversion.

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 growing our go-to-market team.

As a 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 an 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.

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.
