How a computer-science side project became a bootstrapped survey empire - no venture money, millions of users, and a stubborn belief that research should be cheap enough for anyone to run.
A New Era for Human Understanding.
The Barcelona company that decided forms should feel like a conversation - and got millions of people to actually finish them.
How a two-person idea about watching strangers click around a website turned into a $1.3 billion research empire that now sits between companies and the customers they can no longer afford to guess about.

It started with a professor's throat cancer and a basement in Provo. Two decades later, Qualtrics turned the humble survey into a $12.5 billion category called experience management - and taught the enterprise to listen.

Maze, Typeform, Voxco, Refiner, Usersnap, Simplesat and SurveySparrow each own a slice of the feedback market. Zoho Survey is betting that the slice matters less than the suite it plugs into.

Long before Discourse threads and Patreon tiers, a Dutch company was turning online communities into listening posts for brands. CMNTY has spent nearly two decades using customer conversations as research nobody else could run.

Three research-tech pioneers walked into a merger and came out as one platform. Forsta - Norwegian for 'to understand' - now wants to be the connective tissue between everything a company knows about its customers, employees, and patients.
Bloomfire sells companies a cure for their own forgetfulness - an AI knowledge layer that makes video, PDFs and buried Slack answers searchable, and then quietly tells you which of them have gone stale.

Founded by growth operator Hudson Liao and AI engineer Paulo Nascimento, it aims to compress market research and outreach from hours into minutes.

The Jakarta-based firm has raised about $14.2M to date, most recently a $4.3M Series B in 2025.

Dana Kim is the co-founder and CEO of Highlight, a New York-based product intelligence platform that modernizes in-home product testing for consumer brands. A former qualitative market researcher who spent years collecting insights the slow way - standing in stores with paper surveys for brands like Coca-Cola and Nike - she went to Wharton for an MBA, met co-founder Ethan Kellough, and built a technology-driven alternative that pairs a proprietary consumer community with logistics automation and AI analytics. Founded in 2020, Highlight has raised more than $30 million and works with brands including Nestle, Procter & Gamble and Mondelez. Kim has been named to GreenBook's 2022 Future List and Inc.'s 2024 Female Founders 250 list.

Founded in 2016 by former McKinsey consultants Sascha Eder and Germain Chastel with Anuja Ketan, NewtonX serves Fortune 500 companies, top management consultancies, and financial institutions that need trustworthy, fraud-resistant data to make high-stakes decisions.
