Account Manager, Paris

Supply Finder at a glance

• A programmatic supply decision platform: for every campaign, it finds the inventory that will perform across 10+ SSPs and keeps tuning it, so buying teams deliver what they sold, with margin.
• Founded in 2025 by three founders from adtech, with 21 years of combined experience on the SSP side.
• Already in production: 10+ buying teams, 10+ SSPs connected, 3 continents.
• Measured results: on a published A/B test, -45% cost per video view and -49% CO2 per 1,000 impressions.
• Funded: a pre-seed round closed with business angels, completed by Bpifrance and bank financing.

The role

You are the main contact for your clients' teams. Execution is automated: the platform builds the media plans, creates the deals and keeps optimising them in flight. You run the control tower: you follow more than a hundred campaigns at once, spot what is drifting and decide when to step in. Your time goes where it counts: understanding your clients, making the calls, growing the accounts.

• Reporting line: to Kevin, co-founder in charge of sales, with a list of accounts defined from day one.
• Your scope: your accounts, their volume on Supply Finder and the satisfaction of their teams.
• Your impact: every account you grow shows directly in our revenue.
• What comes next: when the sales team grows, you will be its first point of reference on account management.

What you will do

1. Grow your accounts. More campaigns launched, more traders using the platform, and clients you move to a yearly volume commitment.
2. Run the control tower. You follow all your clients' campaigns while they run, spot the gaps (pacing, KPIs, margin) and decide when and how to step in.
3. Onboard new clients. You train their teams and set up their way of working in the tool: custom rules and steps that the platform then applies on its own to each of their campaigns.
4. Make performance visible. You show each client what the optimisations changed, and use it to open the conversation about what comes next.
5. Carry the voice of the field. You bring your clients' needs back to the product team and test new features with them first.

Who you work with

At our clients. Teams that sell campaigns to their own clients with a promised result (a cost, a volume, a KPI), and must deliver it while keeping their margin, in France and abroad. You work with their three jobs: the sales people who sell the campaign, the account managers who follow the advertiser, the traders and AdOps who run it.

At Supply Finder. Kevin, product and account, sets your goals and supports you day to day. Antoine, co-founder and CTO, receives your field feedback and gives you new product features first. Maxime, co-founder and CEO.

You do not need to know everything about SSPs when you join: we teach it, it has been our job for more than 20 years.

How we work

A startup does not have to mean vagueness. Here is the framework you will find when you join.

• A three-stage onboarding, over 90 days. First the business and the tool, then your first accounts paired with a founder, then your portfolio on your own, with clear goals at each stage.
• Written goals. The volume of your accounts, the commitments signed, how much traders use the platform: you know what you are expected to deliver, and how we measure it.
• Simple meetings. A weekly review of your accounts, a monthly review of your portfolio, a product meeting where your field feedback is handled.
• Solid ground. A funded company, clients who pay every month, a product that already runs on live campaigns.

Your profile

Must have

• 3 to 4 years in programmatic, at a trading desk, a media agency, an SSP or a publisher, part of it managing client accounts with growth targets.
• Solid practice of at least one DSP (DV360, The Trade Desk or equivalent), PMP deals day to day, and the habit of steering many campaigns from the numbers.
• Fluent French and professional English: our clients and partners work in both.
• At ease with a head of programmatic, and able to understand a need from a brief.

Nice to have

• Experience in programmatic operations at an SSP.
• Experience negotiating yearly commitments or volumes with media buyers.
• Personal, entrepreneurial or non-profit projects, especially if you have already built something with AI tools.

The founders are not in Paris every day: we expect you to carry your accounts on your own after your first quarter, with us in support.

Package and terms

The process

Four steps, a reply within 48 hours after each.

1. First conversation with Kevin: the project, the role, what you expect.
2. Role interview: we start from a campaign or an account you managed, and dig into your choices.
3. Working session: we open a real, anonymised campaign portfolio in Supply Finder, and you tell us what you see, what you would do and what you would tell the client.
4. Meeting with the three founders, then an offer.
