Testimonials
We supported them, and they talk about us.
Nathan MinguetCEO, Bienesis
“Junko is a key partner for complex new-market exploration work, and a sparring partner to executives on strategic issues. Their support enabled us to de-risk our understanding of the market and the construction of our first 5-year business plan. The team is pleasant, responsive, attentive, and always relevant.”
Matthieu TanguyCEO, Effy
“Junko helped us imagine and test a new service, able to diversify and strengthen our business model, at the crossroads of energy and building renovation. In just a few weeks, their entrepreneurial, pragmatic approach enabled us to pick up signals from the field, bring out the most promising avenues and reveal a robust, tested strategic direction.”
Thomas VroylandtCo-founder, Kantiles
“Working with Junko on our strategic positioning feels like watching all the scattered hunches, blind spots and long-lingering to-do lists come together before your eyes, workshop after workshop, with no extra mental load. They have a rare ability to pull out the salient points and synthesise them. Their method, structure and rigour take you, in very little time, from pieces that fit together poorly to solid foundations: a value proposition, well-built customer segments and an action plan to move forward. I warmly recommend them.”
FAQ
Frequently asked questions.
What is an Operating Partner?
A partner at your side, who does the work with you rather than just advising. We embed in the team to deliver, not only to recommend.
When is it worth reaching out to Junko?
When you need a boost, or when you are stuck. If budget is your concern, we adapt our engagements to your means: sparring partner, operating partner, part-time CMO, and many other formats. Either way, we will be glad to talk with you about your project. If we can make an introduction or lend a hand along the way, we will do it with pleasure. And with a smile.
At what stage of maturity do you step in?
Seed, Series A, Series B... At every new sequence, we step in to de-risk your company and accelerate its development. We are just as useful at the genesis of an innovation project, when it is still only a challenge (for example: “how do we diversify our revenue and build recurring income?”), as when it is more mature (for example: “is there a willingness to pay? What is the right offer? What is the right price point?”).
Do you support fundraising?
Yes, we help you prepare your raise. We are not fundraisers ourselves, but we work with specialised partners for the execution.
Do you offer training?
Yes. We run training sessions on business model innovation, for example: Circular Business Models, Pricing Strategy, or AI for Business & AI Prototyping. Each one is tailored to your teams and your challenges.
Where do you work geographically?
We are based in France, but we regularly work on international projects, in English, driven by globally present groups such as Bouygues Bâtiment International, Merck or Michelin.
