London · Hamminkeln · 20 years inbound · 4 years all-in on AI

We help B2B teams turn AI from experiment into compounding revenue.

Helium42 was founded on a simple belief: AI only matters when it ships. We pair education with implementation so your team owns the systems we build — long after we step away.

What is Helium42?

Helium42 is the B2B AI consultancy for European mid-market.

We work with companies of 50 to 5,000 employees across the UK, Germany, and broader Europe. We deliver four services: strategic AI consultancy, an AI-produced content system, the Salesman Sam AI sales agent, and AI education programmes. Every engagement ends with your team independently running what we built.

Our mission

Make AI useful, owned, and inevitable inside European mid-market companies.

We don’t leave behind a dependency. Every Helium42 engagement ends with your team running the AI systems we build — documented, monitored, and improving on its own.

Our story

Twenty years of inbound. Four years all-in on AI.

Helium42 didn’t start from a deck. It started from a frustration: most AI consulting either dazzles with demos and disappears, or hands over an opaque black box. Neither builds capability. We chose a third path.

Inbound foundations

Clwyd founds Whitehat — a HubSpot Diamond partner serving European mid-market. Two decades of running content systems, MarTech stacks, and revenue ops for B2B teams becomes the lens we look at AI through today.

The first AI experiments

Early production work with GPT-2 and bespoke NLP pipelines feeds into our AI development practice. Most projects of that era were useful for two weeks and shelved. The pattern was clear: AI without an operational home dies in the demo.

Workshops & transformation

200+ AI transformation workshops with senior leaders across Europe. Boards understood the opportunity. The repeated blocker was always the same — nobody internally owned the system after launch.

Helium42 launches

Peter joins as co-founder. We codify the education-to-implementation methodology into a single offering — the Helium42 engagement model — with The Content System and Salesman Sam as productised flagships.

Two offices, one team

London and Hamminkeln, native English and Deutsch, focused exclusively on European mid-market. Every project ships with a knowledge-transfer plan from day one.

What we believe

Four principles that shape every engagement.

These aren’t marketing copy. They’re the calls we make when a project is hard.

01

Systems over stunts

A working pipeline that ships every week beats a flashy prototype that lives in a deck. We measure success by what is still running six months after we’ve gone.

02

Compounding over campaigns

One-off campaigns peak and fade. We design AI systems that get cheaper, faster, and better the longer they run — the kind of asset that shows up on a balance sheet.

03

Human + AI, not human or AI

We build for augmentation, not replacement. Your domain experts stay in the loop — their judgement is the moat. AI handles volume and speed; humans handle taste and accountability.

04

Measure what ships

Every Helium42 system is wired to a KPI on day one — pipeline created, articles indexed, response time, conversion lift. If we can’t measure it, we don’t build it.

Who runs Helium42

Two founders. One team. No layers.

Helium42 is deliberately small. Every client engagement runs through one of the two founders — you talk to people who can answer technical questions and make commitments in the same conversation.

Questions evaluators ask

Questions evaluators ask before our first call.

Direct answers to what people most often ask before engaging Helium42.

What is Helium42?

Helium42 is a B2B AI consultancy for European mid-market companies of 50 to 5,000 employees. We are based in London and Hamminkeln. Our work pairs education with implementation so client teams own the AI systems we build.

Who founded Helium42?

Helium42 was co-founded in 2024 by Clwyd Probert (CEO and CTO, formerly founder of Whitehat — a HubSpot Diamond partner) and Peter Vogel (COO and CMO, marketing transformation specialist). Both founders take the first call on every engagement.

Where is Helium42 based?

Helium42 operates from two offices: London (80A Uxbridge Road, W12 8LR) and Hamminkeln (Nordrhein-Westfalen, Germany). Both offices share calendars and serve the entire European mid-market.

What does Helium42 actually do?

Four offerings: AI strategy and transformation consultancy, an AI-produced content system, the Salesman Sam AI sales agent, and AI education programmes. Every engagement ships with a knowledge-transfer plan from day one.

How long has Helium42 been operating?

Helium42 the brand launched in 2024, but the founders track record stretches back two decades. Clwyd founded Whitehat in 2005 and has delivered 200+ AI transformation workshops across Europe. Peter has built and led marketing and operations teams across Europe with 2M+ EUR monthly digital media budgets.

Which languages does Helium42 work in?

English and German fluently across every engagement. Documentation, workshops and asynchronous communication run in either language depending on the client team. Most internal artefacts default to English unless requested otherwise.

AI transparency

How Helium42 uses AI itself.

  • Public content. Drafts of articles, landing pages, and case-study summaries are AI-assisted and human-edited before publication. Headline statistics are human-verified against client engagements.
  • Client work. Every AI-built artefact (content, response, lead score, recommendation) is logged, attributable, and auditable by the client team. Clients always retain the right to remove AI from any process.
  • Personal data. We do not train external models on client data. Models used in production engagements are documented per project, including provider, region, and retention policy.
  • Compliance posture. We follow the EU AI Act (Article 50 transparency obligations, effective 2 August 2026) and the UK ICO 2025 guidance on AI in marketing. Compliance details and current sub-processor list available on request.
