## About

Series is a social networking startup that works entirely through iMessage rather than a separate app. Users text a dedicated Series AI number, describe who they are and who they want to meet, and receive a carousel of up to ten profile cards, each with a photo and a stated request. If two people show interest, they can talk in a private thread without sharing phone numbers. It was founded by Yale students Nathaneo Johnson, the chief executive, and Sean Hargrow, and is based in New York, with an office in Chelsea. The company has raised $5.1 million in pre-seed funding in total. An initial $3.1 million round, led by Anne Lee Skates of Parable, was reported in April 2025, and the full $5.1 million was announced in April 2026. Investors include Pear VC, Venmo co-founder Iqram Magdon-Ismail, Reddit chief executive Steve Huffman and GPTZero founder Edward Tian. Series has said it passed one million messages and 10,000 daily active users, and that students use it across more than 750 campuses. These figures come from the company and have not been independently verified. The company is pre-revenue, and Dealroom reported that it was considering enterprise monetisation. Series matters to the dating industry mainly as a signal of where investor money is going. Most use is business-oriented, according to Johnson, though TechCrunch-sourced coverage notes some users look for dates or friends. Business Insider grouped it with other AI networking tools in its list of funded social and dating startups, the piece DII cited when reporting on loneliness startups.
