The Story of Weaviate: Building the Database Infrastructure for an AI-Native Future

Great companies often start with a founder spotting something others have missed. In a recent episode of Category Visionaries, Weaviate founder Bob van Luijt shared how an early fascination with machine learning led to building crucial infrastructure for the AI revolution – years before most people saw it coming.

The entrepreneurial bug bit Bob early. Born in 1985 in the Netherlands, he started his first business before turning 20, selling websites during the early internet boom. “I very quickly figured out, hey, wait a second, I’m building some skills on the web, and people are interested in that,” Bob recalls. Even while studying music in college, he kept one foot firmly in the software world, building e-commerce solutions and websites.

But the pivotal moment came in 2015 when Bob encountered something fascinating in early language models. These models could take words and assign them coordinates in mathematical space, revealing semantic relationships. “If you take the two words Eiffel Tower and you combine them together, then the distance between the word Paris was smaller than, for example, London,” he explains. This seemingly simple capability hinted at a revolutionary new way to organize and search information.

The vision crystallized at Google I/O 2016. When Sundar Pichai announced Google’s shift from “mobile-first to AI-first,” Bob had an epiphany. “I got it immediately,” he recalls. “I’m going to start a project that is going to be a search engine that focuses on doing that not at the scale of Google, but doing that for any developer, at any company, at any scale that wants to build with machine learning.”

But being early meant years of evangelism. “AI now is very hot,” Bob notes, “but I can tell you it was not in 2016.” He traveled across continents – the US, Europe, even Japan – demonstrating the potential of machine learning in search. The project existed as open source before becoming a company, allowing the technology to mature and find its audience organically.

The transition to a company wasn’t planned. Bob had been running successful consulting businesses, but something was missing. “I wanted to have a product business rather than a pure consulting business,” he explains. “When the project started to grow, I was like, this is it. This is the opportunity.”

The company’s growth accelerated dramatically after launching their serverless offering in April 2023, perfectly timed with the explosion of interest in AI following ChatGPT’s release. But rather than simply riding the AI hype wave, Weaviate maintained its focus on building fundamental infrastructure.

This commitment to infrastructure stems from Bob’s conviction about AI’s future role. “AI will not only be something that’s sprinkled over products that you and I use today,” he predicts. “No, no, it will be at the heart of these products.” This vision drives Weaviate’s evolution from vector database to comprehensive AI-native platform.

Looking ahead, Bob sees Weaviate becoming essential infrastructure for the AI revolution. “We want to grow into this AI native platform where we enable developers. Doesn’t matter what size company you work for, it doesn’t matter where you’re coming from. If you’re a developer that wants to build AI native applications, we want to be here to help from the infrastructure level.”

The story of Weaviate isn’t just about building a successful company – it’s about recognizing a fundamental shift in how software would be built and creating the infrastructure to support that future. For technical founders, it’s a reminder that the biggest opportunities often come from seeing beyond current trends to the underlying changes that will reshape entire industries.
