Summary
EliseAI, an AI-driven automation platform founded in 2017, announced a $350 million Series F funding round on September 29, 2026, at a $4 billion valuation. The round was co-led by existing investors Andreessen Horowitz and Bessemer Venture Partners, alongside new investor Ontario Teachers' Pension Plan. The valuation represents a 100% increase from the company's August 2025 Series E closing at $2 billion, reflecting accelerating institutional confidence in its business model and market opportunity.
The company has achieved significant operational scale, reporting $200 million in annual recurring revenue as of summer 2026 and claiming penetration into one in six apartment units nationwide. Co-founder and CEO Minna Song emphasized the breadth of EliseAI's platform reach, noting that its software handles core property management functions including leasing, maintenance, and renewal workflows across residential properties.
A key strategic development announced this month was the launch of Apollo, an AI assistant integrated natively into the EliseAI platform. Song described Apollo as capable of "acting across every role on a property team," streamlining task execution within the existing leasing and operations infrastructure. The company positioned Apollo as an efficiency multiplier rather than a standalone tool, since it operates within the unified platform where these operational workflows already execute.
On the healthcare side, EliseAI automates patient-related administrative work for specialty physician groups, spanning inbound inquiry handling, referral management, scheduling, insurance verification, chart preparation, and follow-up processes. The company's dual-vertical strategy reflects CEO Song's thesis that housing and healthcare represent the two largest expense categories for American households, making operational efficiency in these sectors economically material for end customers.
The rapid valuation ascent—from $2 billion to $4 billion in 13 months—alongside strong revenue growth and continued backing from tier-one venture capital firms signals sustained investor appetite for back-office automation software addressing legacy-heavy, high-value industries. The scale of the round and investor syndicate suggest confidence in EliseAI's ability to defend and expand its market position against emerging competition in enterprise AI automation.
