Chief Data Officer

Sparteo is an independent suite of AI-powered advertising technologies built on sustainable, sovereign infrastructure.

Since 2018, we’ve been reshaping programmatic advertising to make it faster, more transparent, and more profitable by building the most direct path between publishers and advertisers.

But we don’t stop here: wherever attention lives, on the web, in apps, on CTV, and beyond, our mission is to monetize audiences, across every device. Our data-driven tech delivers 30% higher revenues for our clients on average than traditional solutions. Our Solutions:

• Actirise: the display tech designed for performance
• FastCMP: the consent management platform specifically designed for business purposes
• Meetscale: the most advanced SSP for Publishers and Ad Networks
• Viously: the ultimate all-in-one video tech solution

Behind Sparteo’s growth is a team of 100+ talents across 11 countries, united by a shared ambition to redefine the future of digital advertising. Our dedication has placed Sparteo among the most dynamic tech players in Europe:

• FT1000 ranking:
  Among the fastest-growing European companies in 2024 & 2025
• The Europas:
  Featured in the list of 100 hottest startups
• Pixalate Ranking: #1 Web SSP in France with our Actirise solution, overtaking Google Ad Exchange

These milestones are just the result. What truly sets us apart is how we work: at Sparteo, we don’t settle, we act.

• We are Drivers, not passengers:
  We take the wheel and own our results.
• We are data-obsessed:
  Facts guide us, not assumptions, not egos.
• We think as one:
  Collective goals come before personal wins.
• We trade off:
  We simplify, prioritize, and go for high-impact results.
• We solve problems:
  We own challenges and turn ideas into action.
• We say what we do:
  Radical transparency is how we grow, no fluff, no hiding.

Our client-facing products and real-time analytics are best in class. The first mission is to bring the same level to our internal teams (Sales, CSM): internal data APIs, unified dashboards and one shared set of KPI definitions.

The CDO leads the entire Data & AI function and works hand in hand with the CTO. This is not an administrative role, but that of a leader with strong scientific and mathematical authority, able to understand and challenge the work of senior data scientists and engineers, and to support them on the toughest problems. The goal is not to out-code the team but to structure it, set direction and act as a mirror.

You will orchestrate the synergy between infrastructure, Artificial Intelligence (including Generative AI) and Business Intelligence.

• Restructuring:
  Structure the Data department to support Sparteo’s growth.
• “Architect” Vision:
  Define the organizational building blocks (Heads/Leads per pillar) to elevate global technical maturity.
• AI
  
  Roadmap:
  
  Define and execute the strategy for integrating LLMs and Agentic AI to automate yield optimization and internal processes, including our internal data agent and conversational analytics for clients (RAG, text-to-API).
• Single source of truth:
  One set of KPI definitions, formulas and naming across the group.
• Data governance & compliance:
  Own data governance across the group, including GDPR compliance in partnership with our DPO, data retention and minimisation.
• Documentation & knowledge management:
  Help a strong team move from largely oral knowledge to written, durable processes.
• Budget ownership:
  Manage the Data & AI annual budget and decide where to automate and where to hire.
• Representation:
  Carry the voice of Data and AI to the board, investors and external partners.
• Holistic Management:
  Lead the Heads/Leads of each pillar…
