Caddy
Caddy is a personal AI for everyday work that lives in your text messages and responds to voice. Built by the team that led product and design for Loom's AI suite, it connects to the tools people already use - email, calendar, Slack, Linear, Notion - and gets work done without forcing anyone to open yet another app. You text or talk; Caddy handles the tickets, reminders, scheduling and follow-ups. The company is part of Y Combinator's Fall 2025 batch and is based in New York City.
Applied Brain Research
Applied Brain Research (ABR) is a Waterloo, Ontario AI hardware company spun out of the University of Waterloo's Centre for Theoretical Neuroscience. It builds brain-inspired chips and software that run real-time AI - full-vocabulary speech recognition, text-to-speech and sensor processing - directly on edge devices at power levels measured in milliwatts. Its patented state-space models and the Legendre Memory Unit power the TSP1 Time Series Processor, which ABR calls the world's first single-chip solution for full-vocabulary speech recognition, doing the work of cloud voice AI while consuming 10 to 100 times less power.
Wispr Flow
Wispr Flow is a San Francisco-based AI voice dictation platform that converts natural speech into polished, formatted text across any application at roughly 220 words per minute - about 4x faster than typing. Built by two Stanford AI researchers, the company has quietly become the voice layer that 270 Fortune 500 companies rely on, combining a 10% word error rate (vs. 27% for OpenAI Whisper), 100+ language support, and context-aware formatting that automatically adjusts tone and style based on the active app. With $81M raised and a $700M valuation as of late 2025, Wispr Flow is racing to become the default voice-first operating system for a billion users.
