Partnering with Dexa

Dexa was born out of a viral tweet. 

Riley Tomasek couldn’t remember how much magnesium he needed to sleep better, a health tip he heard on his favorite podcast, Huberman Lab. While podcasts are important repositories of knowledge, they’re infamously tricky to search. So Riley did what any engineer would do—he spun up an app that could search through Huberman Lab’s published episodes.

Then he shared the app on X. Within 24 hours, Andrew Huberman himself reshared Riley’s work. Within a week, Riley’s original post racked up half a million views. His DMs were filled with messages from fellow podcast listeners. Could he add additional features? Could he release the app more widely? 

With LLMs on the scene, search is going through its biggest transformation in decades. It’s easier than ever to publish expert-sounding content, but the ways experts disseminate and monetize their knowledge are still the wild west. Dexa is building a new search experience—one where knowledge from prominent content creators is easy to dig through. We believe Dexa has the potential to fill a new whitespace created by LLMs between peer-to-peer forums (e.g. Reddit, Quora) and traditional search (Google), directing high-intent knowledge seekers to specific answers from the people they trust. 

Over the past year, Riley, who previously co-founded Flight (acquired by Figma), turned his project into a product and raised $6M from The General Partnership, Otherwise, Abstract Ventures, HF0, Maple VC, and Vercel CEO Guillermo Rauch. Dexa's ambitions for search go far beyond replacing ten blue links with two short paragraphs. They are building an entirely new knowledge graph around people, not web pages — a place where world-leading experts can tailor their counsel to millions, and people can find wisdom, not summaries.

To start, Dexa’s AI-powered search engine indexes podcast content, but the technology is built to support additional modalities. In its current form, Dexa analyzes and transcribes podcast conversations with precision—it can tell users who was speaking, what they said, and when they said it in any episode. Dexa’s chat-based UX also allows users to ask follow-up questions, follow specific podcast shows they trust, and discover new content based on their interests. Today, over 50,000 people use Dexa per month to search through podcasts. They ask questions like, “How do I ask for a raise at work?” and “What is the best programming language to learn in 2024?” and “What are the benefits of intermittent fasting?”

Dexa has officially partnered with Huberman Lab, Seth Godin, Lewis Howes, Tom Bilyeu, and others to kick off their search experience. Huberman Lab’s Dexa is available at Dexa.ai, but it is also embedded directly on the Huberman Lab site, powering search for an audience of millions. As Dexa expands its partner program and the scope of questions it can direct to expert answers, we believe it can become a default starting point for finding answers on the internet.
