About Karumi

Karumi is a Y Combinator–backed (F25) company building the first agentic product-demo platform. Our AI agent joins live video calls, runs personalized product demos, reasons through prospect questions, clicks around the product in real time, qualifies leads, and routes them into the CRM — 24/7, in any language. We're a small, fast-moving team replacing a slow, manual part of the sales motion with autonomous agents.

We hire ahead of need and screen carefully. Expect a sharp bar, a fast process, and real ownership from day one.

What you'll do

Build Karumi's demand engine. As an early marketing hire you'll own a mix of content, demand gen, and brand — telling a sharp story about agentic selling and turning attention into qualified pipeline.

Responsibilities

• Own content and narrative: how we explain agentic demos to a skeptical market.
• Run demand-gen experiments across channels and double down on what converts.
• Build the website, launches, and campaigns alongside the founders.
• Partner with sales to keep the inbound-to-pipeline flow tight, and report on what's working.

You're a fit if you

• Have 3+ years in B2B SaaS marketing, ideally a generalist or growth-leaning role.
• Can write — clearly, with a point of view — and ship without a big team.
• Are data-driven about channels and funnels.
• Want to define a category, not just market into an existing one.

Nice to have: early-stage / founding marketer experience, product marketing chops, design or no-code fluency.
