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:

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.

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.

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.
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.
