Olto, the AI demo engineer transforming how B2B teams demo and sell software, has raised $5.1 million in pre-seed funding. The round was co-led by Nexus Venture Partners and The General Partnership, with participation from Afore Capital, Recall Capital, Ligature, FirstHand and notable founders and executives.

Olto transforms every buyer interaction, whether a live demo call, an outbound touch, or an inbound visit, into a high-converting product experience by generating context-aware demo environments and interactive product tours for every opportunity in the CRM. Designed for the entire GTM motion, Olto operates as an always-on expert AI demo engineer.

The company was founded by seasoned Amazon executives Kintan Brahmbhatt and Jean-Baptiste Chaput, with veteran Amazon engineer Pranav Midha joining as founding engineer. Brahmbhatt co-founded Amazon Music, where he led its product team, and Amazon’s podcasting business, which he ran as general manager. He also co-invented Prime Video's X-Ray feature – the contextual information layer that transformed how millions of consumers discover and experience content.

“At Amazon, we pioneered just-in-time personalization to change the way consumers engage with media,” said Kintan Brahmbhatt, CEO and co-founder of Olto. “With Olto, we’re bringing that same magic to B2B software. Every seller gets an expert demo engineer that’s always on, always current, and always tailored to the buyer.”

B2B buyers increasingly expect consumer-grade, personalized experiences, while revenue leaders face mounting pressure to accelerate sales cycles and do more with smaller teams. Traditional product demos remain heavily manual, inconsistent, and dependent on scarce solutions engineering resources, creating bottlenecks that slow deal velocity.

To solve this challenge, Olto’s AI-native platform integrates directly with a company’s CRM and live product, overlaying intelligent, prospect-specific data across real interfaces. Behind the scenes, Olto combines a custom entity resolution engine and a flexible orchestration layer that leverages multiple LLMs to personalize demos on the fly. It adapts seamlessly to ongoing changes to the underlying product, eliminating the delays and maintenance burden of legacy demo tools.

"AI is upending traditional approaches to B2B sales," said Abhishek Sharma, managing director at Nexus Venture Partners. "Sales teams spend countless hours on manual demo preparation, only to deliver generic experiences that don't resonate with prospects. Olto's AI-first approach eliminates this time drain and creates genuinely targeted experiences that lead to faster sales cycles. Kintan and JB’s unique background in building delightful ML-powered products at Amazon gives them a compelling advantage in solving this problem."

"What excited us about Olto is how naturally Kintan and JB are applying their consumer product instincts to one of the biggest bottlenecks in enterprise software sales–demo delivery," said Phin Barnes, co-founder at The General Partnership. "They've built an AI-native system that actually enhances how buyers experience a product beyond simply automating workflows.”
