图书馆员:WhatsApp优先的AI助手筹集200万美元,然后转向房地产
新加坡的WhatsApp优先AI助手在Product Hunt上排名前三,增长至25,000名用户,由Golden Gate Ventures领投筹集了200万美元种子轮——然后转向房地产经纪人。
The Librarian (TheLibrarian.io)
做的是什么生意
The Librarian is an AI personal assistant that lives inside WhatsApp, iMessage and SMS: it connects a user's Google apps, Slack and Notion, answers by chat or voice, and executes scheduling, email drafts, reminders and follow-ups.
启动资金:US$2 million seed round announced 2025-11-13, led by Golden Gate Ventures, with angels including Yelp CEO Jeremy Stoppelman and Twenty Five Ventures.
起因
Co-founded in November 2023 by Tiago Alves, who ran Aptoide's Asia business (nearly 100M monthly active users) and then was a partner at Golden Gate Ventures, and Neil Kumar, one of Yelp's first engineers and founding CTO of Karat. After ChatGPT's November 2022 launch, the two set out to build 'Siri for everything, but on WhatsApp' — one chat interface for email, scheduling and documents.
经过
By April 2025 the product had only ~500 monthly active users, and VCs told Alves to come back with 5,000. A Product Hunt launch (Top 3, 1,000+ upvotes) plus focused marketing delivered 10x growth; the founders then added paid plans (Basic $9.99/mo, Pro $19.99/mo) and got their first 100 paying users. In November 2025 the company raised a $2M seed led by Golden Gate Ventures. Analyzing the first paying users, the founders found three clusters — real estate agents, insurance agents and startup founders — and in December 2025 decided to go deep into real estate.
结果
Still live. By February 2026 the pivot was live: a voice-first AI companion for real-estate agents that turns a WhatsApp voice note into a lead profile, surfaces matching PropertyGuru listings and sets tasks and reminders, with the whole flow under three minutes. The company continues to operate from Singapore and Seattle.
背景
The Librarian是一个内置于WhatsApp、iMessage和短信的AI助手。它连接到Google应用、Slack和Notion,通过聊天或语音接收指令,并执行任务——起草邮件、安排日程、搜索、跟进。由Tiago Alves(前Aptoide、前Golden Gate Ventures)和Neil Kumar(前Yelp、Karat创始CTO)于2023年11月在新加坡共同创立。
赌注:专业人士通过聊天来管理工作:“万能Siri,但在WhatsApp上”。增长缓慢——到2025年4月仅有500个月度活跃用户。2025年7月Product Hunt发布(前三,1000多个赞)带来了10倍增长和第一批100个付费用户。2025年11月:由Golden Gate Ventures领投的200万美元种子轮,Yelp CEO Jeremy Stoppelman参与天使投资;有25,000个活跃用户。
分析谁在付费后,创始人发现了三个群体——房地产经纪人、保险代理、初创公司创始人。在2025年12月他们选择了房地产;到2026年2月转型开始:语音优先AI伴侣,将WhatsApp语音笔记转化为销售线索档案,匹配PropertyGuru列表,在三分钟内设置任务。从新加坡和西雅图运营。
这件事要成立,得有什么
- 聊天原生分发的赌注奏效了:居住在WhatsApp内消除了安装障碍,创始人称这是在Product Hunt发布后采用率飙升的原因。
- 创始人将早期付费用户视为市场数据:三个付费客户画像指向房地产经纪人,于是他们跟随该垂直领域。
- 融资里程碑按顺序达成——5000用户,然后付费用户,然后种子轮——让两人团队无需大型产品团队就能筹集200万美元。
- 一位曾在风投一侧(Alves曾是Golden Gate Ventures合伙人)的创始人理解里程碑游戏,并将其用作路线图。
可借鉴之处
分发胜于功能:住在WhatsApp里让两人创业公司以200万美元种子轮达到25,000用户;当早期付费客户聚集在一个垂直领域时,跟随他们。
后续进展
截至2026-09-02,The Librarian在新加坡和西雅图运营。在2025年11月种子轮之后,它转向为房地产经纪人提供语音优先AI伴侣:WhatsApp语音笔记变为销售线索档案,匹配PropertyGuru列表,并转化为任务。2026年2月的转型保持了聊天原生界面,但将焦点缩小到一个垂直领域。牵引力:截至2025-11-13,在美国、欧洲、新加坡有25,000个活跃用户。
