Overview

The way companies innovate is broken. The systems built to create and protect ideas can’t keep up with the pace of change. Today, 90% of S&P 500 company value is intangible (e.g., IP) — yet R&D and IP teams spend half their time buried in manual work, sifting through patents and paperwork instead of pushing the frontier forward.

Ankar AI is building the AI Platform for the Trillion Dollar Innovation Economy — a suite of tools that helps inventors explore, create, and protect ideas. We remove friction from the invention process, starting with IP protection and expanding toward creation and exploration.
