Senior product leadership where you need it, without the full-time hire.

Charlyne Graveline

Head of Product at Geolid

“The engagement allowed us to step back and reflect on our key challenges, and to better understand where our main levers for impact lay. We were able to structure a clear plan, realign our priorities, and quickly initiate transformative decisions. Without them, I would never have managed to drive such rapid change within the group.”

Elise Applanat

Co-founder at MerciYanis

"When I changed roles, I had to relearn everything. The support helped me regain confidence, structure our product vision, and align the entire team on a clear course. We went from a demand-driven product to a vision-driven product. Without them, I would never have been able to make such rapid changes within the group."

Charles-Henri Poirot

CPO at Sahar

“The support enabled me to structure the Product function as a true strategic lever. I was able to clarify the vision, accelerate buy-in from the executive committee, and lay the foundations for a scalable organization to support our diversification. Without them, I would never have managed to drive such rapid change within the group.”

Guillaume Boiret

CEO at PhantomBuster

“The audit enabled me to quickly gain clarity and make the right decisions at the right time. The impact was immediate: greater clarity, a better pace, and renewed collaboration. Without them, I would never have managed to drive such rapid change within the group.”

Gregory Hachin

CEO at Ector

« Stellar's intervention transformed a frozen project into a clear, actionable plan aligned with our strategy. Their ability to challenge without imposing, to coach without dominating, made all the difference. Without them, I wouldn't have been able to get the group moving so quickly. »

Victor Ruelle

Head of Product at Joko

“Having an experienced mentor who listens and takes concrete action enabled me to take a step back, structure my recruitment and lay solid foundations for our Product team. The exchanges helped me gain confidence and gave me the tools to face the future with serenity. Without them, I'd never have been able to get things moving so quickly within the Group.”

Jean-Rémi de Maistre

CEO at Jus Mundi

“We were all convinced that we needed to structure our Product organization, but we lacked the framework to move into action. The Stellar audit enabled us to make the key issues objective, formalize our intuitions, and above all, launch the priority initiatives immediately, without delay.”

Pauline Renoux

Head of Product at Stanley Robotics

"I didn't know where to start redefining our Product strategy. In less than two months, the Stellar method enabled us to involve all the teams, align our vision and lay solid foundations. Stellar's CPOs are not just facilitators: they bring real convictions and on-the-ground expertise. Pragmatic and effective support."

Nate Lowe

CTO at Aldebaran

"Mentoring with Stellar was a real wake-up call. I clarified my role, managed my associates better and made decisions I'd been putting off for too long. In three months, we found our PMF, signed our first structuring contracts and attracted new investors. Stellar's support had a decisive impact at a key moment for the company. I'd recommend it to any founder in the early-stage phase."

Baptiste Le Bihan

CEO at Linc

"We knew our product was becoming a risk for the company, but we had neither the experience nor the clarity to restructure the team and recruit the right Product profile. Matthieu, with his experience as founder and CPO, immediately challenged us to clarify our needs and objectives. Thanks to his approach, we avoided looking for the 'five-legged sheep', targeted the right candidates and structured an efficient recruitment process. Stellar's peer assessment and benchmarks were decisive."

Maxime Barbier

CEO at Timeleft

"What I really appreciated was Stellar's ability to challenge my intuitions with concrete data: salary benchmarks, skills matrices, detailed profile analysis. It saved me an incredible amount of time and avoided costly recruitment mistakes."

Joan Alfonso

Product Leader at Smetz

"Mentoring with Stellar helped us clarify our priorities, smooth the relationship between CEO, Product and Tech, and lay solid foundations to support our growth. It helped us to make decisions we'd been putting off for months, and to become more efficient in customer onboarding and delivery. Without them, I'd never have managed to move the lines so quickly."

Florian Bouron

CEO at Mozzaik365

“The bulk of the value of the engagement came from the quality of the Stellar team: pragmatic, experienced, and able to dive deep into issues rather than just skim the surface. The audit enabled us to reset our technical organization, recruit a new leader, and finally define a credible plan to address technical debt and improve velocity. Without them, we would have continued to fall behind, put our growth at risk, and I would never have managed to drive such rapid change within the group.”

Pierre-Louis Giros

CPO at Allshare

"What I particularly appreciated was Stellar's ability to adapt their recommendations to our level of product maturity. We were starting from scratch and feared that their recommendations would be disconnected from our realities, or that the investment plan would be too heavy. On the contrary, their plan was fully adapted, yet ambitious. That's all it took to get the CODIR and all the teams on board."

Pierre Touton

CEO at Bow Medical

"The audit enabled us to catch the wave at the right time. Before, I used to pull my teams, now I push them: they have adopted the vocabulary, the priorities and are challenging each other. Stellar was able to transform our findings into a concrete action plan, combining operational benchmarking and pragmatism in the field. Without them, I'd never have managed to get the Group moving so quickly."

Simon Baldeyrou

Directeur Général at Phenix

"Stellar's audit was a real wake-up call, enabling us to clarify our vision, recruit a CPO in record time and set up a governance structure that finally streamlined our decision-making. This support enabled us to move from a logic of frugality to a dynamic of investment, essential to relaunching our growth and preparing for international expansion."

Arthur Ménard

Head of Product at Pony

"Mentoring with Stellar has been a real gas pedal. It enabled me to take a step back, structure my ramp-up as Head of Product, and unblock key issues like retention or collaboration with Tech. Having an external, experienced and benevolent viewpoint changes everything when you're in the middle of a Scale phase."

Laure Pichereau

CEO at Siview

"Working with Stellar was a real catalyst. In just a few weeks, we clarified our Roadmap, structured the Product/Marketing team and set in motion decisions that I'd been putting off for months. I gained in serenity, posture and, above all, impact. It's simple: without it, we'd never have been ready to Scaler internationally."

Julien Coulet

CEO at Tenacy

"The Stellar method clarified our Product direction, and enabled us to realign and better structure our execution. The support we received saved us months in terms of Product structuring and team mobilization, a real gas pedal in achieving our growth objectives."

Iscliff Lebée

COO at Dayuse

"Stellar succeeded in mobilizing the entire COMEX and teams to move from project mode to product mode! An essential transformation to achieve our post-LBO growth objectives."

Pierrick Arnal

CEO at Predict4health

"You might expect a surface-level audit, yet the action and recruitment plan provided by Stellar is a real Game-Changer for my teams, all the more so in the context of our Series A Closing. I recruited our new CTO in the process, saving 2 months in his Onboarding!"

Elliot Boucher

CEO at Edusign

"It was really interesting to have an external point of view. Stellar's solutions were very relevant. We clearly wouldn't have thought of them and the operating procedure was perfectly communicated to the team. I particularly appreciated the efficiency of the intervention; in less than 2 weeks, I received a clear strategy to help my startup accelerate on the product and the business!"

Thomas Levallois

CFO at Araïko

"We gave you demanding specifications, and you met them to the letter. Great exchanges, great clarity in the deliverables, and a real jolt for us. If I had to rate the assignment, I'd give it a big 5/5. You unlocked important things, way beyond the product."

Antoine Lafont

CEO at Diogen

"The initial exchange with Stellar was an electroshock: the questions asked revealed a huge gap between their daily lives and Product standards, which triggered an immediate awareness."

Emile Karam

Cofounder & CPO at Garantme

"For the short amount of time we spend with our teams, the efficiency of the process is beyond reproach. The clear, actionable deliverables enable us to ask the right questions and trigger constructive discussions. It's exactly what we expect from an audit, but with unprecedented speed".

Guillaume Cruz

Cofondateur & CPO at Zeliq

"What I appreciated most was the responsiveness and attentiveness of the Stellar team. Thanks to them, we were able to effectively prioritize our Product decisions and quickly adopt the best practices adapted to our maturity."

Mike Cuingnet

CEO at Tennders

"There was a before and an after to Stellar. They compensated for the absence of a Head of Product and the lack of seniority in our team in just a few days a month. They revolutionized our strategy and overhauled our processes from top to bottom. In 6 months, my employees are more engaged than ever, my customers are converting on our new model and our users are seeing new features released every month."

Ethan Frajdenrajch

Co-fondateur at OKS Media

"Stellar's coaching was a game-changer for OKS Media. With the help of our Stellar CPO, we completely revamped our strategy and optimized our development processes. The solutions provided were concrete and quickly actionable. We saved a huge amount of time and avoided many unnecessary expenses."

Romain

CEO at N&C

“It’s very simple: before Stellar, I didn’t have a Product function and we were operating blindly. They helped me raise my standards and prepare my team for the upcoming growth stages.”

Quentin Sauvée

CEO at Jaji

“The engagement is effective and pragmatic. They get straight to the point and involved our teams over a very short period. The Stellar team saved us two months.”
