Marriage Pact
Marriage Pact is a research-driven matchmaking company, born as a 2017 Stanford economics class project, that runs an annual values-based questionnaire on college campuses. Instead of judging looks or swiping, students answer roughly 70 questions about their deepest values, and a stable-matching algorithm pairs each person with their single most compatible 'backup plan' on campus. Founded by Liam McGregor and Sophia Sterling-Angus, it has expanded from one campus to more than 100 schools and over 600,000 participants, and raised a $5M seed round in 2022 to keep building relationship technology.
CoffeeSpace
CoffeeSpace is a mobile-first, AI-powered matchmaking platform that helps founders, talent, and startups find each other - swiping their way to a cofounder, a first hire, or a team to join. Often described as 'Hinge for cofounders,' it uses granular filters and dual-sided compatibility matching to pair ambitious builders by skills, working style, time commitment, and equity preferences. Founded in 2024 and based in San Francisco, the app has grown to 30,000+ users across 100+ countries.
Jobcase, Inc.
Jobcase is a Cambridge-based social platform built for the workers most job sites overlook - hourly, frontline and blue-collar Americans. With more than 110 million registered members and roughly 20 million monthly actives, it pairs a community forum and resume tools with machine-learning job matching, earning rankings among the largest U.S. online career destinations. Founded by Fred Goff and Tony Deigh out of the wreckage of an AI hedge fund, Jobcase makes money from employer advertising and recruiting partnerships while keeping the core product free for job seekers.
Clubhouse
Clubhouse is a voice-first social app built by Alpha Exploration Co. It started as an invite-only live audio room platform that briefly mesmerized Silicon Valley in 2020-2021, then pivoted to friend-centric voice messaging and custom AI voices as the live-audio boom cooled.
