What We Do

Benbase is an AI-powered employee benefits brokerage that pairs smart automation with real licensed advisors to deliver better benefits with less admin. Behind the scenes, our AI agents handle plan comparison, enrollment, compliance, bill audits, and administration — the 80% that's repetitive and rules-based. Up front, experienced benefits professionals provide the judgment, empathy, and expertise that actually matter. The result: benefits that work for your business and your people, without the dread of open enrollment season. We serve companies from 5 employees to 500 — startups, nonprofits, schools, trades, and everyone in between — because every team deserves access to expert guidance, not just the ones with enterprise budgets. What we believe: • Benefits should be a competitive advantage, not a headache • AI should do the heavy lifting so humans can do the real thinking • Simplicity scales — clarity over complexity, always Based in the SF Bay Area and serving clients nationwide. Built by benefits people who spent decades wishing this platform existed — then decided to build it. Let's talk: benbase.com
