The Challenge

Most fractional CTOs defer to vendors when the conversation turns to search architecture, NLP pipelines, RAG systems, or ML model integration. The Develomentor team does not — because this is where we have spent our careers.

Led by Grant Ingersoll — co-founder of Apache Mahout, core Apache Lucene & Solr committer, OpenSearch contributor, and author of Taming Text, the best-selling reference on search and NLP for software practitioners — Develomentor brings practitioner depth that most consultancies cannot match. Grant founded Lucidworks and built production search systems used by Fortune 500 brands. Our team has worked on search at places like Apple, Reddit, Morgan Stanley, and Lowe’s Home Improvement — companies where search, ranking, and relevance are core to their product experiences.

01

Your fractional CTO is learning on the job when it comes to AI and search

02

Your Gen AI prototype works in the demo and fails in production

03

Relevance directly impacts your bottom line, and no one understands how to improve it

Where We Engage

Independent Evaluation of Your Search & AI Architecture

We review your architecture, retrieval quality, and model choices and tell you what's working, what's expensive theater, and what needs to change. Led by Grant Ingersoll — Apache Lucene/Solr committer, OpenSearch committer, author of Taming Text. No vendor affiliations.

Implementation, Not Just Advice

Most advisors recommend a stack and move on. Our team builds it. From search infrastructure and NLP pipelines to RAG integration and model deployment, Develomentor engineers own the architecture and write the code — vendor-neutral, with no one to answer to but you.

Relevance, Ranking, and Quality You Can Measure

"I can think of no better person to teach a class on search with machine learning than Grant Ingersoll. Through his open source work on the Apache Solr search engine and as a founder of the Apache Mahout machine learning framework, Grant has done more to teach developers about the technology concepts and applications of ML and search than anyone in the business. If you type “machine learning” and “search” into Google, the top result is Lucidworks, a company that Grant was the driving force for. This is a no-brainer, take this class from Grant!"

Adam Cheyer — Co-Founder of Siri

"Grant has a unique combination of breadth and depth in the search space, from designing a search solution for performance and stability at scale, while also having deep expertise in the internals of the engine, such as text analysis, relevancy tuning, query optimization, and index design. You won’t find a better teacher to provide a solid foundation in the theory as well as how to apply it when building real world search applications."

Tim Potter — Search Engineer, Apple

"Grant is an established expert in the area of Search, Machine Learning, and AI! He has the mind of a researcher, an educator and has demonstrated the applicability of these deep topic areas into real-world products used by enterprises. What better way to learn than from someone who is a published author, a hands-on practitioner, and an industry expert?"

Sameer Maggon — CEO of SearchStax

"Engaging Develomentor was hugely valuable to our team. Grant Ingersoll’s deep expertise and ability to collaborate with our Product and Engineering teams helped focus our project, identify options, and ultimately define a technical strategy that best aligns with the needs of our business and customers."
