Right now he is trying to give you an exoskeleton
Walk into any agency war room the night before a big pitch and you will find people drowning. Forty tabs open. A half-built deck. Someone three coffees deep, certain there is a perfect stat out there somewhere. Justin Wohlstadter built Waldo for exactly that person, at exactly that hour.
Waldo is an AI research platform for the people who research for a living - the strategists, planners, and creatives who need to sound fluent in a category they had never heard of yesterday. It collects and monitors enormous amounts of online data and turns it into the kind of insight that wins business. The company describes the job plainly: get smart fast, for pitches, brand, and creative work. Brands like Airbnb, Kettle & Fire, and Conair have signed on.
In September 2025 the company closed a $10 million Series A, a venture-scale round run not out of San Francisco but out of New Orleans. A month later Wohlstadter and his team posed at the city's Idea Village to mark it, planting a flag for serious technology in a city better known for jazz than for cap tables.
What he is really chasing is older than Waldo and older than AI. He wants to hand the individual what he calls an "exoskeleton of knowledge" - a way to sift, faster, through everything the rest of us simply give up on. The product is new. The obsession is not.
Waldo did not arrive as a slick AI assistant. It started as a humble Chrome extension in 2021: a search engine for professionals that sat on top of Google and Bing and let you hyper-tune a query with a couple of keystrokes. Press one key and it would highlight the data points. Press another and it would surface paragraph previews. A feature he nicknamed "X-ray" let you hunt inside a page itself - "like Command + F on steroid," as he put it.
That extension was a clue, not a destination. The destination was always the whole workflow: find, save, share. "Our hope is to own this whole research workflow," he said, "and to make every part of that workflow much, much better and faster."
