About Us

We are a New York based tech startup working on evidence based expert search. We were founded in 2020 by Dr. Chang Wang. Our mission is to produce high quality expert search results that people can actually use on a daily basis.

Currently, we offer four services:

  • Expert Search
  • Expert Profile Lookup
  • Collaborator Lookup
  • Technology Landscape Analysis


We track research papers (>100M), US patents (>10M), government grants(>3M), trademarks(>14M), SEC filings (all available to SEC), and maintain up-to-date profiles for more than 11M experts across all fields of science and technology.

A fairly complicated text analysis platform has been built to support our services. The platform contains:

  • a central knowledge graph storing hundreds of millions of documents;
  • several search components providing paper, patent, grant and expert search results;
  • a number of site crawlers tracking new information in real-time;
  • a pipeline with dozens of built-in natural language processing and machine learning components to analyze documents and provide functions of search.
