Karumi is an AI agent that joins live video calls to deliver personalized product demos, 24/7 and in any language. It engages visitors at peak intent and introduces a new generation of interactive, self-guided demos that turn curiosity into conversion.
A high-intent lead arrives, fills a form… and then waits. Hours, sometimes days. And when they finally get a demo, it’s often generic, rushed, or badly timed. This delay kills conversions.
And smaller accounts? They never get a demo at all.
We built Karumi to fix this.
Karumi is an AI demo agent that shows your product in a live, interactive way — instantly — 24/7.
It talks, reasons, clicks around your app, opens tabs, adapts the demo to the prospect, and handles qualification on its own. No more waiting.
No more “can you do Thursday at 4pm?“.
Every inbound gets a personalised demo right when they show intent. Teams are using Karumi to:
convert more visitors into qualified meetings
cover segments that never got demos before
combine discovery + qualification + demo in a single flow
handle big spikes of inbound during launches
We’re Pablo and Toni, co-founders of Karumi (YC F25).
Real customers are already using it in production and seeing strong conversion lifts.
Great idea. If there were a tool that monitors messages on social networks and automatically invites people to such presentations — that would be really cool! But that’s already an idea for another startup...
Looks really cool! Is this fully baked you think? Or are we a few AI models away from this dream of a product. Very interested if it works as ideally as wanted
Congrats on the launch! Love the blend of demo and qualification in one flow. How does Karumi decide what to highlight for different prospect types?
Neat product and well crafted. The quality of the voice of the agents is amongst the best I’ve seen out there and the deployment team is incredible at getting your platform setup. We use their agents today to onboard clients and help drive expansions, our team loves it.
Proud to be a user! Can’t wait to see how it will improve and evolve.
What's up Product Hunters! 👋 — wild to be posting here, because for years I was on the other side upvoting cool products, and now I’m actually launching one.
We started Karumi because the way people buy software today has evolved faster than the tech meant to support that behavior. Modern buyers expect immediacy, control, and personalization, but today’s demo tools make them wait, guess, or watch something generic.
Here’s what we mean:
Demo 1.0 — humans: Personal, high-quality, but impossible to scale. Your best reps can only run so many calls, and most visitors never stick around long enough to book one due to too many drop off points in your funnel.
Demo 2.0 — videos, demo sandboxes, and clickthrough tours: Scalable, but not interactive or personalized. They show the product, but no one actually talks to you, answers your questions, or guides you based on what you need.
We’re building Demo 3.0 — where an agentic AI product expert can meet prospects instantly and walk them through a personalized demo in real time.
Since our @Y Combinator launch last week, Karumi has already delivered 3,000+ demos of Karumi, totaling tens of thousands of session minutes of real product engagement. It’s been surreal watching an AI agent do what no human team (or static video tour) could ever match or scale to.
We’d love your thoughts, questions, and ideas on where agentic demos could go next. We’re here all day and excited to finally share this with the PH community! ❤️
Hey Product Hunters 👋
Most SaaS teams still demo like it’s 1990.
