About Annie Case
Annie Case started her career as a consultant at Bain & Company in San Francisco. She advised clients in technology, private equity and education. She then worked in product and business operations at Uber, where she supported the SVP of operations and helped scale Uber Eats to new international markets.
Case joined Kleiner Perkins in 2018 and later became a partner. Kleiner's site now lists her as an Advisor who previously served as a partner. Her focus there was consumer technology, digital health and enterprise software. She studied Human Biology (BA) and Management Science & Engineering (MS) at Stanford and played on the Stanford women's soccer team. She is a Kauffman Fellows member (Class 26). Her X bio now reads "investor" and lists Kleiner Perkins as a previous role.
Crunchbase lists Case's personal investment in The Sentience Company's seed round (March 2026). Her X posts show her backing the company publicly. Beyond that, a full list of personal angel checks with years is not public. Most of her documented investing was done through Kleiner Perkins.
On March 26, 2026, Case posted her support for The Sentience Company, whose founder said it raised $6.5M. The founder described the company as building a personal model, a digital twin of a person's mind, for each user. Case wrote that the team is trying to build a product reflecting an individual's context, style and taste.
At Kleiner Perkins she also worked with Lotus Health, which NFX Signal lists as an AI company (seed June 2024, Series A February 2026). She also worked with Health Universe (seed, March 2026) and Ambience, which Kleiner lists under healthcare AI.
Kleiner's bio and the Kauffman Fellows profile describe a focus on early-stage consumer, healthcare and marketplace companies, plus enterprise software. She is based in the San Francisco Bay Area. NFX Signal lists a $2M to $50M range for her Kleiner Perkins investments. That range reflects her work at the firm, not her personal angel checks. She has not published a personal angel check size that we could find.
