Account Manager at Lemrock
- Company: Lemrock
- Location: Paris (on-site)
- Employment type: Full Time

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
We are accelerating. The product works, clients renew, the market is taking shape. As our first Account Manager, you own the relationship with our brands from the moment they sign: you make their first campaign a success, you prove it with the numbers, and you grow each account from there. You report to the Head of Sales and write the customer playbooks with the Head of Sales and the CEO.
Account growth
Take over each brand at signature: onboarding, campaign setup, first results
Own the ongoing relationship: the next campaign is always planned, the next step always dated
Own and exceed quarterly renewal and expansion targets on your portfolio (>100 brands today)
Customer success & performance
Understand every account's performance in depth: what the numbers say, why, and what to do next
Share it with rigor: clear reporting, regular performance reviews, no surprise at renewal time
Turn results into recommendations brands act on: budget, targeting, next campaigns
Be the brand's voice internally when something needs fixing, and the first to know when it is
Playbooks
With the Head of Sales and the CEO, write the account management playbooks (onboarding, reporting cadence, renewal motion), then run them
Automate what can be automated: AI in the reporting, the follow-up, the account research
Market feedback
Feed what you hear from live accounts back to Sales and Product: what works, what doesn't, what brands ask for next
Profile
Must-have
2-7 years in account management in the media, adtech, digital, marketplace or e-commerce ecosystem
You have personally owned a portfolio of brand accounts with a renewal or growth target. Running campaign logistics for someone else's accounts does not count.
Sharp with numbers: you read a campaign report in seconds, defend it in front of a marketing director, and can tell us your portfolio size, your retention rate and your expansion figures without looking them up
Rigorous: every account has a plan, every review has a date, every commitment is tracked
AI-forward: you use AI tools in your daily workflow and have already automated part of it
Professional English
A plus
Experience with brand-side marketing / e-commerce decision-makers and media agencies
Fluency with adtech metrics (CPM, CPC, ROAS)
Startup or scale-up experience
What we offer
Competitive base + attractive variable + equity (BSPCE)
The first Account Management seat in the commercial team: >100 brands to grow from day one, the customer playbooks to write
A product that works, clients that renew, a demanding team
Paris 11e, on-site with up to 1 day remote per week
Start date: ASAP.
