Founded by Grant Ingersoll — former CTO of Wikimedia Foundation, co-founder/CTO of Lucidworks, author of best-selling Taming Text, and Apache Lucene, Solr, and OpenSearch committer — Develomentor places senior technology, product, and data leaders inside the companies that need them.

Senior practitioners. Embedded delivery.

Grant and the Develomentor team have led engineering organizations through the moments that decide a company's trajectory — from founding and scaling a VC-backed startup's engineering org to running the 150+ person tech team behind one of the ten most-visited sites on Earth, to committing to Apache Lucene and Solr long before search-relevance and retrieval became board-level conversations.

We bring that bench to founders, operators, and investors as fractional CTOs, CPOs, and CDOs — accountable for outcomes, not slide decks. Every engagement is led by Grant and staffed with senior practitioners we have shipped alongside for years.
