BigBrain

The company's primary business is providing a digital entertainment platform where users can compete in live, multi-player quizzes for cash prizes. The business model is centered on players paying an entry fee, typically starting at a $1 minimum, to enter a contest, with the winner or winners taking the prize pool. The platform hosts contests every 15 minutes on a wide array of topics, from 90s movies and sports to more academic subjects like state capitals. This structure targets casual gamers and trivia fans who enjoy skill-based competition. Revenue is generated from the fees paid by users to participate in these paid contests. The company utilizes third-party payment processors to handle deposits and withdrawals for users' accounts.

BigBrain's service is an iOS application that features various games. The main trivia game involves 12 timed questions, where both speed and accuracy contribute to a player's score and their position on the leaderboard. A key differentiator is its focus on specific areas of expertise rather than just general knowledge, with questions created and fact-checked by experts. The platform also employs proprietary technology to deter cheating. Beyond traditional trivia, the company expanded its offerings to include a survey-based game called "200", and other games that mix elements of classic puzzle games like Tetris and Boggle. The company raised a total of $13 million over two funding rounds, including a Series A round of $8.49 million in April 2023, from investors such as First Round Capital, BoxGroup, and Ludlow Ventures. As of July 1, 2025, BigBrain announced it has ceased operations.
