Karumi recently launched!

Launch YC: Karumi - Your AI demo agent. 24/7.

"The first agentic product demo platform where prospects receive personalized demos, in a video call, instantly."

TL;DR: Skip the reading! Karumi delivers personalized product demos, and it’s faster if their agent just shows you! → Demo now

Founded by Toni Lopez & Pablo Omenaca

They faced the problem firsthand at their previous company, StackAI (YC W23). Their GTM team struggled to keep up with product changes and deliver consistent demos at scale. They were constantly asking, “How do I do X?”, so they built an AI agent to do it for them:

  • Toni Lopez (CTO) - founding engineer at StackAI (YC W23), software developer at IBM Research, serial entrepreneur
  • Pablo Omenaca (CEO) - COO & founding engineer at StackAI (YC W23), MIT grad, BCG Gamma

Most companies still demo like it’s 1990. Be honest: when was the last time you sat through a full onboarding flow? Or found someone available right now to give you a live demo?

Users don’t want to follow a script or wait; they want to see how your product makes their lives easier.

That’s why the team built Karumi, an AI agent that delivers personalized demos, 24/7, and in any language.

Forget pre-recorded videos. Karumi gives your users a real demo experience - a live, interactive video call with an AI agent that:

  • Matches human reps in clarity and engagement.
  • Is always available, regardless of timezone.
  • Has access to a browser (it opens tabs, navigates your product, etc.)
  • Is hyper‑personalized, pulling in every piece of contextual data (prospect profile, product knowledge) to tailor the conversation.
  • Auto‑trains on your product and business changes, staying up‑to‑date without manual input.

Why did they build Karumi?

As SaaS companies scale, inbound leads grow quickly. Demo requests pour in, and human reps can only handle so many before leads start slipping through the cracks. The result:

❌ High-intent leads wait days for a personalized demo.

❌ Smaller accounts go unserved.

❌ Reps spend time chasing the wrong fits instead of closing deals.

❌ Quantity of demos takes priority, leaving quality and personalization behind.

Traditional sales motions don’t scale linearly with demand. Every new lead either adds friction or requires more headcount, creating bottlenecks and lost opportunities.

Why does it matter?

Every minute of delay between interest and engagement means lost revenue, especially in today’s crowded software landscape. Karumi closes that gap, giving every lead personalized attention at the moment of highest intent, including those who are currently underserved.

Their customers use Karumi to:

Improve conversion rates from landing page visits to meetings.

Serve segments that previously went unserved.

Shorten sales cycles by combining discovery, qualification & demonstration steps.

Capture inbound demand during product launches or marketing surges.


Their vision

Demos are just the beginning. Their vision is to become the interface between people and software

Karumi agents enhance every stage of your customer journey, making high-touch engagement and personalization truly scalable. Think about onboarding, support, and enablement.
