Overview
EliseAI is a New York-based artificial intelligence company that automates the administrative front desk of two industries — housing and healthcare — founded in 2017 by Minna Song and Tony Stoyanov (TechCrunch). Its chatbots text, email and call renters about apartment tours, maintenance requests, lease renewals and delinquencies, and its healthcare tools handle patient intake, scheduling, insurance checks and follow-ups (TechCrunch). The name invites confusion with ELIZA — the 1964–1966 MIT chatbot by Joseph Weizenbaum, known as the first chatbot in history — but the two are entirely unrelated (Weizenbaum Institut).
The admin-assistant origin
Song and Stoyanov met as undergraduates at Cambridge, but the company came from fieldwork. After graduating, Song moved to New York and took a job as an administrative assistant at a residential real-estate firm — where she watched messaging inefficiencies between management and tenants grind teams toward burnout (TechCrunch). “Recognizing this challenge, Stoyanov and I began creating AI software to automate communication,” she told TechCrunch — and they founded EliseAI in 2017 (TechCrunch).
The bet scaled fast. By August 2024 EliseAI had raised $75 million in a Series D led by Sapphire Ventures at a $1 billion valuation, served 350+ customers including 70% of the top 50 US rental-housing operators, and employed around 150 people (TechCrunch). In 2023 it had already begun its second act — HealthAI, adapted for clinics’ scheduling and billing — betting that the same conversational-AI stack could serve healthcare’s front office (TechCrunch).
$4 billion for the boring work
On September 29, 2026, EliseAI announced a $350 million raise co-led by Andreessen Horowitz and Bessemer Ventures at a $4 billion valuation — roughly double its Series E of the previous August (TechCrunch). The company said its software runs in one in six US apartments and that it had passed $200 million in annual recurring revenue that summer (TechCrunch). Weeks earlier it had launched Apollo, an AI “teammate” built into the EliseAI platform to execute tasks — maintenance requests, lease renewals — inside the property software teams already use (TechCrunch). Song’s pitch: housing and healthcare are “two of the largest expenses for American households,” and EliseAI automates the paperwork nobody else wants (TechCrunch).
What this profile does not claim
This profile does not assert the Series E’s exact terms ($250 million, ~$2.2 billion valuation), which were not verified from a fully read source — only TechCrunch’s “double” characterization of the 2026 round. Customer and revenue figures are company-reported via TechCrunch, not independently audited. No EliseAI first-party material was cited.

What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- Series E terms ($250M, ~$2.2B, August 2025) were not verified from a fully read source; the profile asserts only TechCrunch's "double" figure for the 2026 round.
