Alfred Wahlforss was running out of options. His startup, Listen Labs, needed to hire over 100 engineers, but competing against Mark Zuckerberg’s $100 million offers seemed impossible. So he spent $5,000 – a fifth of his marketing budget – on a billboard in San Francisco displaying what looked like gibberish: five strings of random numbers.
The numbers were actually AI tokens. Decoded, they led to a coding challenge: build an algorithm to act as a digital bouncer at Berghain, the Berlin nightclub famous for rejecting nearly everyone at the door. Within days, thousands attempted the puzzle. 430 cracked it. Some got hired. The winner flew to Berlin, all expenses paid.
That unconventional approach has now attracted $69 million in Series B funding, led by Ribbit Capital with participation from Evantic and existing investors Sequoia Capital, Conviction, and Pear VC. The round values Listen Labs at $500 million and brings its total capital to $100 million. in nine months since launch, the company has grown annualized revenue by 15x to eight figures and conducted over one million AI-powered interviews.
“When you obsess over customers, everything else follows,” Wahlforss said in an interview with VentureBeat. “Teams that use Listen bring the customer into every decision,from marketing to product,and when the customer is delighted,everyone is.”

Listen’s AI researcher finds participants, conducts in-depth interviews, and delivers actionable insights in hours, not weeks. The platform replaces the traditional choice between quantitative surveys – which provide statistical precision but miss nuance-and qualitative interviews, which deliver depth but cannot scale.
Wahlforss explained the limitation of existing approaches: “Essentially surveys give you false precision because people end up answering the same question… You can’t get the outliers. People are actually not honest on surveys.” The option, one-on-one human interviews, “gives you a lot of depth. You can ask follow up questions. You can kind of double check if they actually know what they’re talking about. And the problem is you can’t scale that.”
The platform works in four steps: users create a study with AI assistance, Listen recruits participants from its global network of 30 million people, an AI moderator conducts in-depth interviews with follow-up questions, and results are packaged into executive-ready reports including key themes, highlight reels, and slide decks.
What distinguishes Listen’s approach is its use of open-ended video conversations rather than multiple-choice forms. “In a survey, you can kind of guess what you should answer, and you have four options,” Wahlforss said. “Oh, they probably want me to buy high income. Let me click on that button versus an open ended response. It just generates much more honesty.”
The dirty secret of the $140 billion market research industry: rampant fraud
Listen finds and qualifies the right participants in its global network of 30 million people. But building that panel required confronting what Wahlforss called “one of the most shocking things that we’ve learned when we entered this industry”-rampant fraud.
“Essentially, there’s a financial transaction involved, which means there will be bad players,” he explained. “We actually had some of the largest companies, some of them have billions in revenue, send us people who claim to be kind of enterprise buyers to our platform and our system instantly detected, like, fraud, fraud, fraud, fraud, fraud.”
The company built what it calls a “quality guard” that
Listen Labs Raises $100 Million to Expand Customer Understanding Platform
Listen Labs, an artificial intelligence startup focused on customer insights, secured $100 million in Series B funding on January 17, 2026, led by Andreessen Horowitz. The company intends to use the funds to expand its research capabilities and broaden the application of its technology across various business functions.
From Consumer App to AI Platform
Listen Labs originated from a consumer application developed by co-founders after meeting at Harvard. The initial app garnered 20,000 downloads within a single day, prompting the founders to explore methods for deeper user understanding. This led to the development of the prototype that evolved into the current Listen platform.
Elite Engineering Team
The company boasts a highly skilled engineering team. According to Listen Labs,30% of its engineers are medalists from the International Olympiad in Informatics. This competition also produced the founders of cognition, an AI coding startup. One co-founder was the national champion in competitive programming in Germany and previously worked at Tesla Autopilot.
Aggressive Growth and Talent Acquisition
Listen Labs experienced meaningful growth in 2024, increasing its headcount from 5 to 40 employees. The company plans to reach 150 employees in 2026.The company’s recruitment efforts have been notable, including a billboard stunt in San Francisco that generated approximately 5 million views across social media. Wahlforss noted the company initially operated without basic amenities, stating, “some of our, like early employees, joined the company before we had a working toilet.”
Future plans: Synthetic Customers and Automated Decisions
Listen Labs is developing plans to incorporate synthetic customers and automated decision-making into its platform.The company believes that technical fluency will be increasingly vital across all departments, and is hiring engineers for roles beyond traditional engineering functions, including marketing, growth, and operations.
