Jim Larrison

Jim Larrison has spent more than 30 years working across data, media, technology and human behavior. He is Co-Founder and President of Larridin, a company building a measurement layer for enterprise AI. Larridin gives CIOs, CFOs and engineering leaders a view of what their organizations spend on AI, what it produces, and where to automate next. Larridin's site lists him as co-founder alongside Russ Fradin (CEO) and Ameya Kanitkar (CTO). Tracxn dates the company to 2024, and he also sits on its board, according to PitchBook.

Before Larridin he co-founded Dynamic Signal, an employee communications platform that Sumeru Equity Partners later acquired. PitchBook records that exit as a buyout on 4 August 2021. He also played a key role in founding Firstup (formerly SocialChorus), a workforce engagement platform. Crunchbase lists his current title there as Chief Customer Officer and Founder, and PitchBook lists Chief Customer Experience Officer.

Earlier he held executive roles at comScore (Nasdaq: SCOR), Information Resources and Adify, which Cox Enterprises later acquired. A Brand Innovators speaker bio describes him as co-founder and CRO of Adify and a founding team member at comScore. He began his career at Lever Brothers and Vision Quest Research in Chicago. PitchBook lists a BS in Marketing from Bradley University and an MBA in Marketing from DePaul University. He splits his time between Chicago and Scottsdale, Arizona.

Crunchbase counts 3 investments in 3 portfolio companies, with no lead investments and 2 exits, neither by IPO. PitchBook classifies him as an individual angel investor with active status. It lists two deals: Dynamic Signal in February 2011 and LeadSpend in August 2011. Both are tagged as business and productivity software companies that were generating revenue at the time.

PitchBook records LeadSpend as an exit in September 2015 and Dynamic Signal as an exit in August 2021. Crunchbase's activity timeline also associates him with a May 2023 funding round for Evil Genius Games. The sources reviewed give no deal sizes, round terms or follow-on details for any of these investments.

The public record is small and mostly early in his career. Founders should treat him as an operator who invests occasionally, not as an investor with a large or frequent deal flow.

No public source reviewed lists a personal angel investment by Jim Larrison in an AI startup. His public AI activity is as a founder. Larridin states that it raised $17M in seed funding led by Andreessen Horowitz, with contributions from Gradient, Bloomberg, Haystack, Homebrew and others.

Larridin's product measures AI adoption, spend and impact across both human and agentic work. Crunchbase's company profile names customers including Vertiv, Gainsight, Klaviyo and SurveyMonkey. For AI founders selling to enterprises, his relevant experience is in how large organizations measure, buy and justify technology spend.

Jim Larrison has not published an investment thesis, preferred stage or check size that we could find. PitchBook lists his investor status as actively seeking new investments, but gives no stage or size ranges. His two dated deals in PitchBook are in business and productivity software.

His operating background points to enterprise software, data and analytics, marketing and media measurement, and workforce technology. That is an inference from his career, not a stated mandate. He is based in Scottsdale and Chicago, but no geographic restriction is public.

Founders should not assume a check size or stage. A pitch is more likely to land if it connects to his own work: enterprise software, measurement, workforce engagement or AI adoption inside large companies.
