InstaLILY is a New York-based AI startup working at the cutting-edge of agentic AI. We build autonomous agents at the frontier of enterprise software, machine intelligence, and human-AI collaboration.

What We Do
InstaLILY builds AI teammates for the physical-goods economy: industrial distribution, healthcare, supply chain, manufacturing, and automotive. Our model is simple: one company brain, many teammates. We build company-specific AI-powered brains called InstaBrains. Built on small, specialized language models (SLMs), they codify the customer's knowledge and decisions, like their parts, jobs, and pricing. On top of it, InstaWorkers act as AI teammates inside the tools customers already use, completing the sales, service, and operations work that drives the business.
Why Work With Us
Backed by Insight Partners ($25M Series A) and supported by the Google, NVIDIA, and Microsoft ecosystems, we are one of the fastest-growing AI startups in the country. Our team has already driven over $200M in incremental revenue for customers to date. InstaLILY's architecture has been featured in Google DeepMind's case study showcase.
