Guillaume Renaud
I think, I ship, I build.
And I can do the same for you.
Today
Former developer turned Product Owner, now freelance.
I break down complex projects into steps that actually move forward.
I speak product with decision-makers, business with business teams, tech with developers, design with designers. I bridge them all so everyone understands each other and moves faster.
Scoping and delivery, API-first, in sectors where mistakes are costly: mostly banking, but also hospitality and retail.
Discovery, working with business stakeholders, defining vision and roadmap, scoping complex, cross-functional needs.
I already play this role in my PO missions: the BaaS platform and wealth advisor journey at Delubac, cross-department onboarding. In many teams, there's no real boundary with the Product Owner.
Running the backlog and Agile delivery, working directly with development teams.
Seven years as a Technical PO, from BPCE to Delubac via Carrefour and Louvre Hotels, with a developer background: devs don't need to translate their constraints for me.
I code and ship it myself, from prototype to production.
Atriate, in beta, designed and built solo for web and mobile.A product designed and built solo, from web to mobile.

I was lucky enough to work with Guillaume for 4 years, in a perfectly balanced and effective partnership. Guillaume is firmly focused on solutions and results. Constructive on every project we handled, he brings real energy and persistence to fighting the inertia and friction between teams that can slow down design and delivery.
Pauline Ayrault · Senior Product Manager · Discovery & Delivery
I had the pleasure of working with Guillaume at Delubac and discovering a particularly well-rounded profile. Beyond his role as Product Owner, we worked together on structuring and rolling out agile cycle management across every squad in ClickUp.
Sandra Rei · Application Support & Business Analysis Manager
Guillaume has always known how to strike the right balance between business goals, user needs and technical constraints. That's especially valuable from a development standpoint: exchanges are simple, constructive and pragmatic, with a real ability to listen to teams and challenge solutions when needed.
Charlie Bertrand · Software Engineer · Banking product
Guillaume is an excellent project lead, with a natural people sense and a real talent for motivating teams. His rigour, commitment and inspiring leadership make him a reliable, dynamic and invaluable teammate. I recommend him without reservation to any team looking for someone both skilled and genuinely human!
Thomas Lanquetin · Tech Lead
Guillaume has a real knack for project leadership: he knows how to structure, bring people together and build consensus while still pushing ideas forward and staying firmly results-driven. His test-and-learn approach, combined with his tech background, lets him grasp both business and technical stakes. A true “unicorn” I'd gladly work with again if the chance came up.
Sandra Rei · Application Support & Business Analysis Manager
I worked with Guillaume for more than 2 years. I recommend him wholeheartedly. His technical analysis and project-tracking skills are excellent. His people skills are just as strong.
Jérémy Rey · Tech Lead · Malt review
His communication is effective, relevant and transparent, on top of being pleasant. It helps even out the level of knowledge across the teams working on a topic, which is a real asset.
He never sacrifices the big picture or the strategy just to push his roadmap projects forward faster.
Beyond his project management skills, Guillaume is genuinely pleasant to work with day to day, making the work easy and energising.
Background
Scoping and delivery of the Banking-as-a-Service platform: partner-facing APIs, wealth advisor journey, onboarding shared across multiple departments. KYC and compliance at every step.
Rebuild of the Carrefour Location website (vehicle rental, high traffic), from the technical rebuild through the features that followed.
Replaced a business-critical spreadsheet with an internal platform, across a group of 1,600+ hotels. From scoping with operational teams through to delivery.
Agile delivery on the group's banking applications: user stories, architecture trade-offs with technical teams, UAT, production releases.
Rebuild of the online ticketing platform: functional scoping, backlog, interface between the business team and web/mobile developers.
Swift development for consumer-facing mobile apps: new features, performance, daily work with POs, which triggered the move into product.
Case studies
01 · Context
Banque Delubac & Cie launches a digitalisation programme: open up a Banking-as-a-Service offer to partners, and finally give wealth advisors some visibility. Nothing existed yet. Onboarding happened by email, impossible to track or standardise. On the wealth-advisor side, no tooling at all.
02 · What I did
I scoped all three workstreams, then ran them in parallel: roadmap, backlog, trade-offs with the business teams, working with the design team and steering the technical team. Day to day, from Scrum rituals to API specs, with banking compliance looking over my shoulder.
03 · Result
The BaaS platform is live, in service and used by partners. The wealth-advisor platform shipped in three months, with real-time tracking where there had been nothing. Unified onboarding was being rolled out when I left.
01 · Context
A strategic group process relied on a shared spreadsheet: complex, with no access controls or history. The calculation rules lived in a handful of people's heads, and the file itself had become a risk.
02 · What I did
I analysed the existing process in detail with the operational teams, extracted the implicit rules, then designed the product: access management, SSO, history tracking, data reliability. I turned all of it into specifications and steered the technical teams, with a say on the architecture.
03 · Result
A secure internal platform, powered by a machine-learning system that forecasts occupancy and revenue. The group then asked for a second tool: translating its annual targets into per-hotel, per-metric goals.
01 · Context
The Carrefour Location vehicle-rental website needed a full rebuild, on a PHP / Drupal stack. Traffic to absorb was significant, and the booking journey remained the core of the business.
02 · What I did
I steered the rebuild, from business scoping to production release, then built a backlog of improvements focused on the booking journey and its conversion. Day to day I sat between the business team and the developers, and as a former dev I knew when to challenge an estimate.
03 · Result
Platform rebuilt and in production, followed by regular iterations on the booking journey. Trade-offs on performance and maintainability got decided fast, because I discussed them directly with the technical team.
