Customer Lead

Who we are

Lemrock builds the infrastructure of agentic commerce.

Tomorrow, consumers won't just buy on e-commerce websites. They will discover, compare and purchase directly inside conversational AI interfaces like ChatGPT, Perplexity, and a growing long tail of specialized AI assistants.

For brands, this is a major shift: if they are not present in these environments, they become invisible.

Our mission: enable any brand to exist, sell and distribute in this new channel.

We raised a €7M seed round (the first in Europe on this market), with Jean-Baptiste Rudelle, founder of Criteo, on our board, and the Bpifrance DeepTech label.

Today, Lemrock is already:

• 100M+ conversations per month

• 150+ brand clients

• a $100B market structuring at high speed

The role

As Customer Lead, you own our brand clients after they sign. You make sure every brand gets results from AI channels, you prove it with the numbers, and you grow the portfolio from there. You lead our Agentic Commerce Strategists and keep the most strategic accounts yourself. You report to our CEO, and the role is meant to grow into Chief Customer Officer.

It's the first lead role on the customer side, so you will build the function more than inherit it.

Your mission

Portfolio growth

• Own renewal and expansion across 150+ brands, with a revenue target

• Spot early the accounts at risk and the ones that can do more

• Give every client performance figures they trust, so results speak for themselves when renewal comes

Performance & measurement

• Read the data yourself, explain it simply to marketing and e-commerce teams, and defend your recommendations in front of their leadership

• Be the brand's voice with Product and Tech when something needs fixing

Team

• Lead and coach the Agentic Commerce Strategists: who owns which account, what good looks like, how we prepare a client review…

• Automate what can be automated: AI in reporting, analysis and client preparation

Example projects

• You segment our 150+ brands, flag the accounts at risk and the upsell potential, and set the review cadence for each segment.

• You make conversion measurement reliable across our performance clients, so every renewal starts from proven results.

Profile

Must-have

• 4 to 8 years of experience, in strategy consulting or in an advanced operations role at a startup

• You have been in front of clients or executives yourself: you presented the numbers, held your ground and carried the recommendation

• Strong with data: you build your own analyses and notice when a figure looks wrong

• Commercial sense: you know how a renewal is won and you're comfortable owning a revenue target

• Rigorous: every account has a plan, every commitment is tracked

• AI-forward: you use AI tools every day and have already automated part of your work

• Fluent French, professional English

A plus

• You have managed or coached junior team members

• Exposure to e-commerce, retail, adtech or digital marketing, and comfort with ad metrics (CTR, CPC, conversion)

• Experience leading a customer or client team at a startup

• Degree from a top business or engineering school

Why join

• You work directly with Roxane, our CEO, and weigh on product and commercial decisions

• Commerce inside conversational AI is taking shape right now, and well-known brands are already our clients

• A function to build, with a clear path to Chief Customer Officer

What we offer

• Competitive package

• Well-known brands as your clients from day one

• A high-growth startup in a structurally emerging market

• A fast-paced, high-standard environment
