Guru
Stop running your business on confidently wrong AI. Guru turns scattered company knowledge into a governed source of truth that answers employees and AI agents alike.
BOND
BOND is a San Francisco startup building Donna, an AI Chief of Staff for CEOs, founders and busy executives. Donna plugs into the tools a company already runs on - Slack, Gmail, Notion, Linear, Jira, Asana and more - learns how the organization actually works, and surfaces the highest-leverage moves: what shipped, who is blocked, and the top priorities for the day. Founded in 2025 by Chloe Samaha and Rene Sultan and backed by Y Combinator's X25 batch, BOND aims to give every founder an executive right hand that used to cost a six-figure salary.
Cassidy
Cassidy is a New York-based enterprise AI platform that lets non-technical teams build AI agents and multi-step automations powered by their own internal company data. By connecting large language models to a business's knowledge base, tools, and real-time data, Cassidy automates complex, context-heavy workflows - customer support triage, RFP responses, CRM updates from sales calls, lead qualification and internal knowledge sharing - without writing code. Founded in 2023 by Justin Fineberg and Ian Woodfill, the company raised a $10M Series A in 2025 and is used by more than 20,000 teams.
Knock
Knock is a New York-based notification and customer-engagement infrastructure company that gives developers a single API and dashboard to design, manage, and deliver messages across in-app, email, SMS, push, and chat channels. Founded in 2021 by former Frame.io leaders Sam Seely and Chris Bell, Knock lets product and engineering teams ship cross-channel notification workflows without building and maintaining an in-house system, and now powers messaging for companies like Vercel, Webflow, Amplitude, and Clay.
Blockit AI
Blockit AI is a San Francisco startup building an AI scheduling agent that runs your calendar for you. You cc it on an email or ping it in Slack, and it books, reschedules, and negotiates meetings autonomously - learning which meetings are movable and which are not. When two Blockit users need to meet, their agents talk to each other directly, skipping the human back-and-forth. Founded by former Sequoia partner Kais Khimji and calendar veteran John Han, the company raised a $5M seed round led by Sequoia in January 2026 and says it has coordinated more than 100,000 meetings across 200+ companies.
Pinnacle - AI Coaching
Pinnacle is a New York-based HR-tech startup building scalable AI coaching that lives inside the tools employees already use. Its AI coach, Pascal, embeds in Slack, Microsoft Teams, and video meetings to give managers and employees personalized, real-time guidance drawn from their actual work context - performance reviews, 360 feedback, company competency frameworks, and day-to-day communication patterns. Founded by former accelerator CEO and executive coach Alexei Dunaway, Pinnacle raised a $2.5M seed round in March 2025 to bring executive-grade coaching to every employee, not just the C-suite.
Alexei Dunaway
Alexei Dunaway is the founder and CEO of Pinnacle, a New York and Palo Alto based startup building Pascal, an AI performance and career coach that lives inside Slack, Teams, and Zoom. A Stanford GSB graduate and Fulbright Scholar, he spent five years building an entrepreneur accelerator in Kenya before running an executive coaching practice for venture-backed founders. He now wants to give every worker the kind of coaching that used to be reserved for the C-suite. Pinnacle raised a $2.5M seed round in March 2025 led by eLab Ventures.
