Zuni (by Old House Labs Inc.) is a Chrome sidebar AI copilot built for knowledge workers who refuse to leave their existing tools. Rather than forcing users into yet another chat interface, Zuni sits quietly in the browser sidebar, reads the open tab, understands the Gmail inbox, and surfaces actionable intelligence in real time. Founded in 2024 by Cambridge alumni George Seabridge and Will Taylor (a 2x YC founder), Zuni is backed by Y Combinator (S24) and offers access to the world's leading AI models — GPT-4o, Claude 3.7 Sonnet, Gemini 2.0 Flash, DeepSeek R1, and more — all in one place, without switching apps.
Streak is a CRM platform built entirely inside Gmail, enabling sales, recruiting, fundraising, and support teams to manage pipelines, contacts, and workflows without leaving their inbox. Founded in 2011 by ex-Googlers Aleem Mawani and Omar Ismail through Y Combinator, Streak has grown to 750,000+ users and ~$10M ARR while remaining lean (~35 employees) and profitable — having raised only $1.9M and never pursued follow-on venture funding. It is Google's G Suite Technology Partner of the Year and one of the most capital-efficient CRM companies in the market.
