About Walter Brennan
Walter Brennan is 54 and the chief information officer of a publicly traded specialty chemical manufacturer outside Cincinnati — $3.2B in revenue, roughly 7,800 staff and 23 manufacturing sites worldwide. About 620 people sit in his organisation, half through outsourcing partners, with eight direct reports including a security chief and a chief architect. He reports to the CEO and formally to the audit committee on cybersecurity. Thirty years in enterprise IT and three CIO seats sit behind him, and he lives in Indian Hill with a wife who is a high school principal. What makes him a distinct subject: an enterprise resource planning modernisation in year three of a five-year, $180M program that is yellow on schedule and red on budget, while the board asks what the AI strategy is.
He optimises for prudence and for not dropping a regulatory ball, and he is comfortable being slow about it. He is formal in board settings and warmer one to one. He writes short structured emails signed with a shortened first name, asks for documentation on calls and summarises it back, and barely touches chat tools. His vocabulary is governance: total cost of ownership, the steering committee, the cutover, blast radius, the convergence of plant-floor systems with corporate IT. He does not take outbound vendor meetings at all — the path runs through the supplier portal or a sponsored introduction from an integrator partner. A salesperson who cannot distinguish operational technology from information technology is done.
He is a strong subject at consideration and decision for enterprise software sold to IT leadership outside the technology sector — manufacturers, insurers, retailers, utilities, energy, healthcare. He is the best read in the library on analyst positioning as a gate rather than a badge: a niche placement is a hard conversation and an absence from the grid is harder. He is unbudging on contract terms — liability cap, indemnity, data residency, right to audit, termination for convenience, incident notification, no automatic renewal. He is unusually good at the vendor-durability question, asking what happens to the contract if the company is acquired in eighteen months and what the data exit costs. He is weak for self-serve, mid-market and developer tooling.
His media habits are the most traditional in the leadership tier and genuinely load-bearing: print, direct mail and email score high, and a subscription analyst research portal gets heavy daily use. The day starts at 5:30 with the gym and a financial newspaper in paper, then a CIO trade magazine and an industry weekly for chemicals. LinkedIn is the one social channel that matters, and his posts there are drafted by communications. The sources that decide things are a principal analyst he has worked with for a decade, a regional peer group of a dozen enterprise CIOs, and his integrator partners. YouTube, search, podcasts, connected television and out-of-home sit in the middle. Facebook, Instagram, Reddit and X are low; Threads, TikTok, Pinterest, Snapchat, text messages and app notifications are absent.
