I sat in the CTO seat at AI Energy for three years. The job was not a title. It was product architecture, engineering cadence, and keeping a multi-disciplinary team pointed at one outcome while the market kept moving.
The work started as a build: take an AI product from concept to something industrial operators would actually use. Heavy industry does not adopt technology because the demo is impressive. It adopts technology when the workflow already exists and the new layer fits inside it. That is the gap most technical founders miss, and it is the gap I spent those years closing.
Diligence tests the file, not the demo
Acquisition does not test whether you can write code. It tests whether the technology organization can survive scrutiny. Diligence asks for architecture, access controls, dependency risk, data lineage, and a roadmap that still holds if a key engineer leaves. The file has to exist before anyone asks for it. We kept claim-grade documentation as we went: dated decisions, weekly technical logs, recorded results. When diligence started, we did not scramble. We opened the folder.
That same discipline is what SR&ED Consulting needs and what a Tech Truth Audit produces on a smaller timeline. Buyers and the CRA are not that different. Both want evidence.
Hold the product and the deal at the same time
The hardest stretch was not the close. It was the months when the outcome was still uncertain and the team still had client commitments. A CTO who only optimizes for the deal will let the product slip. A CTO who only protects the product will lose the deal. The job was both: hold the organisation together, manage the technical diligence, and keep shipping.
What the seat is actually for
That is what the CTO seat is for. Not a standing meeting and a slide deck. Someone who has done the build, sat through the exit, and can put that judgment on your business without a $300K full-time hire.
If you are choosing between a hire and a retainer, read When to Hire a Fractional CTO vs. a Full-Time Tech Lead. If you want that judgment on a call, start with Hourly Advisory or the 2-minute assessment.
