About H:

H exists to push the boundaries of superintelligence with agentic AI. By automating complex, multi-step tasks typically performed by humans, AI agents will help unlock full human potential.

The Role

Today, H is known for its story: its founders, its funding rounds, its press. We want it to be known for its value. Your mission is to make H one of the top 3 brands that large-enterprise decision-makers think of in enterprise AI, in France first, then in the US.

You will be our Brand lead, and the owner of the Brand pillar of our marketing strategy, alongside Growth and Product Marketing. You'll take over a brand foundation that is being shaped right now (positioning, identity, messaging house) and turn it into a brand that holds for the next five years in a market that reinvents itself every quarter.

Our brand stance is that of a pragmatic visionary: bold on vision, precise and evidence-led on capability. You'll be the guardian of that balance, making sure every piece of work speaks the language of the boardroom and holds up to the scrutiny of a CTO/builder.

You'll work hand in hand with leadership, Product, Research, Sales, our FDE teams and Communications, and with our external brand and PR agencies.

What You'll Do

Lead the brand relaunch (Foundations)

• Take ownership of the new brand platform: positioning, identity, tone of voice and messaging house, and drive its rollout internally and externally.

• Turn our convictions into a story that is ours: what we believe, why we exist, what makes our approach to enterprise problems unique.

• Build a brand system that flexes by market (France, UK, US) without losing coherence, and that separates our two registers: a bold "vision voice" and a precise "capability voice".

• Set and enforce brand guidelines across every touchpoint: website, decks, events, product, recruiting.

Shift the narrative (Reputation)

• Move the public conversation about H from founders and funding to product, value and customer outcomes.

• Make trust a brand signal: reliability, ownership, resilience and our research-first approach (we own our models, we are not a wrapper), carried through proof rather than claims.

• Co-own reputation with Communications: Brand defines the positioning, Communications amplifies it through PR and executive voice.

Build awareness where our buyers are (Awareness)

• Design the brand plan that puts H in front of large-account decision-makers: flagship events, recurring PR moments, ecosystem programmes, content and campaigns.

• Prepare and lead the brand side of our US launch.

• Partner with Growth so awareness turns into qualified relationships and pipeline.

Earn authority (Authority)

• Grow H's thought leadership around the execution gap in enterprise AI and "AI that actually works".

• Lead strategic sponsorships and labels (e.g. Institut Polytechnique de Paris, our Resilient AI label) and partnerships with academics and consulting firms.

Build the function

• Manage brand budget and agencies (brand studio, freelancers).

• Hire and lead the Brand team as it grows, starting with a Content Manager.

How We'll Measure Success

Your north-star metric is the Brand Awareness Index (BAI), measured on our target audiences only: decision-makers at large accounts (SBF 120 in France, Fortune 500 in the US), from business C-levels to "the builders" (CIOs, CTOs, architects, data and engineering leads).

The index combines aided awareness, unaided awareness and consideration of H in enterprise AI, tracked quarterly by market. Your first milestone is to set its baseline, since none exists today.

Horizon Target First 90 days BAI baseline set in France and the US; brand platform rolled out France Top 3 in aided awareness among SBF 120 decision-makers, then Top 3 in unaided awareness US Top 5 in aided awareness among Fortune 500 decision-makers, then Top 3 in unaided awareness within 2 years for AI for enterprise

Supporting indicators: share of voice versus competitors, and the share of H mentions about product and value rather than founders and funding.

What We're Looking For

• 10+ years in brand, marketing or communications, including for a B2B tech company

• You have led a brand repositioning or relaunch end to end, from strategy to rollout, and can show what it changed.

• You have built awareness among enterprise decision-makers, and you have measured it (brand tracking, share of voice, consideration).

• You understand deep tech well enough to translate it for a board without dumbing it down, and to defend it in front of engineers.

• You are as comfortable with a CEO and a leadership team as with a brand studio or a PR agency, and you know how to brief, challenge and arbitrate.

• You think in systems and act in details: a clear strategy, a sharp eye for craft, and a bias for shipping.

• Fluent English is required; French is a strong plus.

You Might Be a Great Fit If...

• You have built a brand in an emerging category, where the words themselves were still being defined.

• You have worked across Europe and the US and know how a story needs to flex from one market to the other.

• You care about proof: case studies, customer voices and numbers matter more to you than slogans.

• You are low ego and high ownership, and you like building a team and a function from the ground up.
