JONATHAN GRIZOU
Fractional AI consultant

Jonathan Grizou

I offer consulting services in Data Science, Artificial Intelligence, Machine Learning and Robotics with a focus on tech start-ups. My clients include Entalpic (AI for Chemistry - €8.5M seed), Pollen Robotics (Embodied AI - Acquired by HuggingFace), and Relativ (Conversational Analytics). My credentials include an award winning PhD in Artificial Intelligence and 40+ papers in top-tier international publications. I have taught AI, Robotics, and Design Thinking as a tenured Assistant Professor, led interdisciplinary teams of Engineers and PhDs, and co-founded two start-ups.

My key services:

// AI Audit & Opportunity Mapping

read more
  • A focused evaluation of your existing processes, software and data assets, and business bottlenecks to identify high-ROI AI opportunities.
  • WHO FOR: Software-enabled SMEs and startups who want to leverage ML and AI but need clear, practical direction before investing in development.
  • OUTCOME: You get a tailored roadmap detailing exactly if, where, and how ML and AI can be integrated into your business to drive efficiency or create new product features.

// Custom Prototyping (Sprint)

read more
  • A rapid fractional sprint to build a tangible, working demonstration (local or deployed) of what custom AI can do for your specific needs.
  • HOW: We pick one project hypothesis for your business and gather relevant data. I iterate quickly and deliver a functional proof-of-concept.
  • OUTCOME: You get a working demo that proves feasibility to stakeholders or investors. From there, we evaluate the results together and map out a clear strategy to turn the prototype into an internal, production-ready product.

// Fractional Team Leadership & Upskilling

read more
  • Strategic oversight and hands-on mentoring for your existing technical teams on concrete projects.
  • HOW: I take ownership of projects and lead your teams. Every week, I provide code examples, teach core machine learning concepts, review architectures, track KPIs and decide on directions. My mission is to translate business objectives into technical realities..
  • OUTCOME: Your company gains immediate access to elite-level AI leadership without the cost of a full-time hire. Over time, your internal engineers are up-skilled, drastically increasing your company's in-house ML and AI capabilities.

// Bespoke: Interdisciplinary & Hard-Tech Challenges

read more
  • Unrestricted, role-fluid partnership for hard-to-define challenges that don't fit into standard boxes.
  • WHY: Because off-the-shelf consultancies break down when faced with novel, deep-tech problems. You need an expert who understands the science, the engineering, and the business realities simultaneously.
  • IN PRACTICE: My role shifts to fill your highest-stakes gaps, whether that means acting as a part-time CTO, stress-testing critical research, or assembling an elite technical strike-team from my network. I have even joined sales teams in the trenches to translate complex tech and help close deals with enterprise clients.

// Affordable
You get long-term project support by paying for just a few hours of expert time each month.

// Flexible
My key goal is to provide dynamic support to suit your changing priorities.
