Kellogg’s record is operating record, not research or teaching: seven years in product marketing at Ingres Corp. (1985–1992) [4]; three years as VP Marketing at Versant Corporation (1992–1995) [4]; nine years as SVP Marketing at Business Objects (1995–2004) [4]; six years as CEO of MarkLogic (2004–2010) [1][4]; a year as SVP/GM of Salesforce’s Service Cloud business (2011–2012) [4]; and six years (2012–2018) as CEO of Planful, then called Host Analytics, before the company sold to a private-equity sponsor [4][5]. He holds bachelor’s degrees in geophysics and applied mathematics from UC Berkeley and an MBA from Saint Mary’s College of California [2]: general-management credentials, not a management-research pedigree.
Since 2018 his standing has run through writing and advising rather than operating: he currently sits on the boards of Dreamdata, Light, TechWolf, and Vic.ai [1], has advised companies including Gainsight, MongoDB, Recorded Future, and Tableau [1], and in 2021 joined Balderton Capital as an Executive in Residence, working part-time with the firm’s portfolio on enterprise-software strategy, go-to-market, marketing, and SaaS metrics [3]. Kellblog, his long-running blog, is where that judgment gets published and pressure-tested in public.
Kellogg is squarely devoted, not adjacent: management, specifically the operating mechanics of running an enterprise-software company, is the entire subject of both his career and his writing. He is not a theorist reaching for management as an application domain; he ran the P&Ls. His word carries the most weight on SaaS operating cadence and go-to-market: pricing, sales compensation, marketing spend, board reporting, and the accountability differences between a manager, a director, and a VP, the terrain of two CEO tenures and an SVP-Marketing tenure [4].
It carries less weight on people-management craft in the abstract (coaching, feedback technique) or on any claim requiring peer-reviewed evidence, since his output is field judgment, not research. The throughline is a practitioner’s plain-spokenness: he writes the operating memo he wishes someone had handed him at each stage of company-building, arguing from what the metrics showed at MarkLogic, Salesforce, and Host Analytics rather than from theory [1].
