Liam Collins is an American entrepreneur and software engineer who is the co-founder and CEO of Proxis, an enterprise AI automation platform focused on AI email agents. Proxis was part of the Y Combinator Summer 2024 batch.[1]
Early life and education
Collins received a bachelor's degree through a dual degree program at Columbia University and the City University of Hong Kong. He later enrolled in an MBA program at the Wharton School of the University of Pennsylvania but left the program to co-found Proxis.[1]
Career
Prior to founding Proxis, Collins worked as an investment banker in the renewable energy sector. He subsequently spent two years as a software engineer at a climate technology startup, where he built systems from the ground up. He also gained experience building AI startups in the health technology and logistics industries.[1]
Collins co-founded Proxis to address what he identified as a need for a more affordable and simpler way for large enterprises to deploy AI models at scale. The company initially focused on fine-tuning and distilling large language models for enterprise use but pivoted to building full-stack AI agent automation after recognizing that enterprises needed more than improved models alone.
Proxis develops AI email agents designed to handle tasks such as sales outreach and customer service on behalf of enterprise teams. The platform works by ingesting a user's full email history and company knowledge base through integrations, then automatically drafting and, optionally, sending email replies. The product offers tiered pricing plans ranging from an Essential plan with auto-drafting capabilities to an Enterprise plan with CRM integrations for platforms such as Salesforce and HubSpot.[2]
The company operates in the software as a service (SaaS) and business-to-business (B2B) sectors, with a focus on productivity, email, and artificial intelligence. As of early 2026, Proxis is based in San Francisco, California, and has a team of approximately three people. Collins is a member of the Forbes Technology Council.[1]
