Brett Bejcek is a solo founder and the person behind Click Clack Labs, a one-person Brooklyn studio shipping consumer products end-to-end: research, data, design, and code. He co-founded Limitless, an AI wearable acquired by Meta in 2025, where he led user research and data science from zero users to product-market fit.

Before that, he built the research and analytics functions at early-stage consumer startups where “the data team” and “the research team” were both him.

His work focuses on the messy front half of 0→1: choosing what to build, finding the signal in tiny sample sizes, and knowing when retention curves are telling you something real versus flattering you. He now spends his time building his own consumer products and advising founders trying to do the same.
