We're too far behind in our development, and that's having a major impact on our business.

"

Our roadmap is unclear, and we find it difficult to prioritize our missions.

"

Our Product knowledge is limited, and we need to be challenged by an expert.

"

We need help to create a strong product culture and align our teams.

"

Part of our product is not clear enough, our churn is too high!

"

I don't have anyone to talk to about the product. I need to be accompanied and listened to.

Some customer reviewswithout bullshit

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

Charlyne Graveline
Head of Product at Geolid

"When I took on a new role, I had to start from scratch. Their support helped me regain my confidence, define our product vision, and get the whole team on the same page. We shifted from a demand-driven product to a vision-driven product. Without them, I would never have been able to implement such rapid changes within the team."

Elise Applanat
Co-founder at MerciYanis

“Their support enabled me to position the Product function as a true strategic asset. I was able to clarify the vision, secure the executive committee’s buy-in, and lay the groundwork for a scalable organization to support our diversification. Without them, I would never have been able to drive such rapid change within the group.”

Charles-Henri Poirot
CPO at Sahar

“The audit allowed 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 been able to drive such rapid change within the group.”

Guillaume Boiret
CEO of PhantomBuster

“Stellar’s intervention transformed a stalled 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 team moving so quickly.”

Gregory Hachin
CEO of Ector

“Having an experienced mentor who listens and takes concrete action allowed me to step back, organize my hiring process, and lay a solid foundation for our Product team. These discussions helped me gain confidence and gave me the tools to face the future with confidence. Without them, I would never have been able to get things moving so quickly within the Group.”

Victor Ruelle
Head of Product at Joko

“We were all convinced that we needed to restructure our Product organization, but we lacked the framework to take action. The Stellar audit enabled us to identify the key issues objectively, formalize our insights, and, above all, launch the priority initiatives immediately, without delay.”

Jean-Rémi de Maistre
CEO of Jus Mundi

"I didn't know where to start when it came to redefining our product strategy. In less than two months, the Stellar method enabled us to engage all teams, align our vision, and lay a solid foundation. Stellar's CPOs aren't just facilitators—they bring genuine conviction and hands-on expertise. Their support is both pragmatic and effective."

Pauline Renoux
Head of Product at Stanley Robotics

"Mentoring with Stellar was a real wake-up call. I clarified my role, managed my team more effectively, and made decisions I had been putting off for too long. In three months, we found our product-market fit, signed our first structuring contracts, and attracted new investors. Stellar's support had a decisive impact at a critical moment for the company. I would recommend it to any founder in the early stages."

Nate Lowe
CTO at Aldebaran

"We knew our product was becoming a risk for the company, but we lacked both the experience and the clarity needed to restructure the team and recruit the right product lead. Matthieu, with his experience as a founder and CPO, immediately challenged us to clarify our needs and objectives. Thanks to his approach, we avoided looking for a 'one-in-a-million' candidate, targeted the right people, and established an efficient recruitment process. Stellar's peer assessment and benchmarks were decisive."

Baptiste Le Bihan
CEO of Linc

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

Maxime Barbier
CEO of Timeleft

"Mentoring with Stellar helped us clarify our priorities, improve communication between the CEO, Product, and Tech teams, and lay a solid foundation to support our growth. It helped us make decisions we had been putting off for months and become more efficient in customer onboarding and delivery. Without them, I never would have been able to make these changes so quickly."

Joan Alfonso
Product Leader at Smetz

“The bulk of the value of the engagement came from the quality of the Stellar team: pragmatic, experienced, and able to delve deeply into issues rather than just skim the surface. The audit enabled us to restructure 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.”

Florian Bouron
CEO of Mozzaik365

"What I particularly appreciated was Stellar's ability to tailor their recommendations to our product's current stage of development. We were starting from scratch and were concerned that their recommendations might be out of touch with our reality, or that the investment plan would be too burdensome. On the contrary, their plan was fully tailored to our needs, yet still ambitious. That was all it took to get the executive committee and all the teams on board."

Pierre-Louis Giros
CPO at Allshare

"The audit allowed us to seize the opportunity at just the right moment. Before, I used to have to pull my teams along; now I push them: they’ve adopted the terminology and priorities and are challenging one another. Stellar was able to turn our findings into a concrete action plan, combining operational benchmarking with practical experience on the ground. Without them, I never would have been able to get the Group moving so quickly."

Pierre Touton
CEO of Bow Medical

"Stellar's audit was a real wake-up call, enabling us to clarify our vision, hire a CPO in record time, and establish a governance structure that finally streamlined our decision-making. This support allowed us to shift from a mindset of frugality to one of investment, which was essential for reigniting our growth and preparing for international expansion."

Simon Baldeyrou
CEO at Phenix

"Mentoring with Stellar has been a real game-changer. It allowed me to step back, structure my transition into the role of Head of Product, and resolve key challenges such as retention and collaboration with the tech team. Having an external, experienced, and supportive perspective makes all the difference when you're in the midst of a scaling phase."

Arthur Ménard
Head of Product at Pony

"Working with Stellar was a real game-changer. In just a few weeks, we clarified our roadmap, built out the product and marketing team, and implemented decisions I’d been putting off for months. I gained a sense of calm, confidence, and, above all, impact. It’s simple: without it, we’d never have been ready to scale internationally."

Laure Pichereau
CEO of Siview

"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 boost in achieving our growth objectives."

Julien Coulet
CEO of Tenacy

"Stellar succeeded in mobilizing the entire COMEX and teams to transition from project mode to product mode! This was an essential transformation for achieving our post-LBO growth objectives."

Iscliff Lebée
COO at Dayuse

"You might expect a superficial audit, but the action and recruitment plan provided by Stellar is a real game-changer for my teams, especially given that we’re closing our Series A round. I was able to recruit our new CTO through this process, cutting his onboarding time by two months!"

Pierrick Arnal
CEO of Predict4health

"It was really interesting to get an outside perspective. Stellar's solutions were very relevant. We clearly wouldn't have thought of them on our own, and the process was clearly explained to the team. I particularly appreciated how efficient the process was; in less than two weeks, I received a clear strategy to help my startup accelerate its product and business development!"

Elliot Boucher
CEO of Edusign

"We gave you demanding specifications, and you met them to the letter. Great communication, clear deliverables, and a real eye-opener for us. If I had to rate the project, I’d give it a solid 5 out of 5. You helped us uncover key insights that went far beyond the product itself."

Thomas Levallois
CFO at Araïko

"The initial exchange with Stellar was a wake-up call: the questions asked revealed a huge gap between their daily lives and product standards, which immediately brought the issue to light."

Antoine Lafont
CEO of Diogen

"Given the limited time we spend with our teams, the efficiency of the process is second to none. The clear, actionable deliverables allow us to ask the right questions and spark constructive discussions. It’s exactly what we expect from an audit, but with unprecedented speed."

Emile Karam
Co-founder & CPO at Garantme

"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 best practices tailored to our level of maturity."

Guillaume Cruz
Co-founder & CPO at Zeliq

"Stellar marked a turning point for us. In just a few days a month, they made up for the absence of a Head of Product and the lack of senior leadership on our team. They transformed our strategy and completely overhauled our processes. In six months, my employees are more engaged than ever, my customers are converting under our new model, and our users are seeing new features released every month."

Mike Cuingnet
CEO of Tennders

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

Ethan Frajdenrajch
Co-founder at OKS Media

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

Romain
CEO of N&C

“Their approach is effective and pragmatic. They get right to the point and engaged our teams in a very short time. The Stellar team saved us two months.”

Quentin Sauvée
CEO of Jaji

“This collaboration allowed us to take a step back and reflect on our key challenges, and to better understand where our main levers for impact lay.
