About Dennis

An AI operator who ships production systems.

Dennis Hettema is an AI operator, not a traditional engineer, who has been building companies since 1999. Today he runs two ventures built by directing AI systems end to end: Hello Revenue, an AI growth platform running paid acquisition for small and mid size businesses, and Armana, a fleet of autonomous vehicles that carry skiers uphill without cables.

He treats hallucination, ungrounded claims and low-quality output as production bugs to be fixed, not accepted. That discipline, and more than four thousand commits shipped to production software in the past year, is what he brings to leadership teams that need AI to work in the real business rather than in a slide deck.

"AI owns the code and the architecture. I own the intent, and the standard it has to meet."

Before founding these companies, Dennis held CTO, COO and CPO seats while scaling businesses, and helped grow Ecologi's B2B customer base from around 100 to more than 18,000, with product and agile leadership as the through-line of his career. Based in Sweden, he works with UK and European clients, fully remote or flexible, on a fractional or short interim basis.

How Dennis Can Help

Four capabilities. One AI operator.

Dennis brings AI strategy, execution and commercial discipline together, embedded in your leadership team for a few days a month or a short interim engagement.

01

Fractional CAIO & Interim Head of AI

Embedded AI leadership for organisations that need someone who has shipped production AI systems, not just advised on them. Available for a few days a month or a short interim engagement.

02

AI-Native Product & Operations Build

Designing and directing AI-run functions that replace manual teams end to end, drawing on direct experience running an AI-operated growth agency with 4,000+ commits shipped to production in the past year alone.

03

AI Quality & Governance

Establishing the discipline to catch translationese, image slop and ungrounded claims before they reach customers, treating AI output quality as a production standard rather than a best effort.

04

Commercial & Growth Leadership

Applying three decades of product, agile and go-to-market experience to scale commercial functions, informed by taking Ecologi's B2B business from around 100 to 18,000+ customers.

Why Work with Dennis

Three reasons clients bring him in.

Most organisations have plenty of AI advice. Dennis is brought in when AI needs to run in production, to a standard, and pay its way commercially.

REASON 01

He ships, not just advises

Two ventures run by directing AI end to end, and 4,000+ commits to production last year. His advice comes from systems that are live, not from theory.

REASON 02

Quality is non-negotiable

Hallucination and ungrounded claims are treated as production bugs. Dennis sets the standard AI output has to meet before it reaches a customer.

REASON 03

He has sat in the executive seats

CTO, COO and CPO roles while scaling businesses mean AI is always tied to product, operations and revenue, not treated as a side project.

Areas of Expertise

Disciplines, functions and sectors Dennis operates across.

Available for fractional and short interim engagements across the United Kingdom, the Nordics, the Benelux and wider Europe, fully remote or flexible.
