An AI-native innovation studio
“AI-native” does not mean “AI-everywhere”
- AI has a cost. Societal, environmental, even business.
- AI is probabilistic. It is not the answer to every situation.
- AI is fallible. Mind the robustness of your processes.
We use AI every day to do better
- To build digital products with real positive impact on experience, adding to perceived and captured value.
- To free up time for analysis by automating repetitive tasks.
- To augment our analysis and accelerate our clients’ positive impact.
How we reconcile performance & impact
- Frugal use. Targeted use, sober agent design, careful model selection.
- Agnostic use. Fast provider switching, open-weight models first.
- Multiplier use of positive impact on companies, people and the living world.
Testimonials
We supported them, and they talk about us.
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.”
Jacques PiatInitiative Leader, Nazca
“Junko has been a precious partner in our exploration of the heavy-goods tyre maintenance world. Thanks to their exploration and field-testing methods, we maximised our learnings and de-risked several directions of our business model. Their entrepreneurial, analytical and pragmatic mindset allowed us to capture reliable signals in the field.”
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.”
Laure Ménager, Martijn Pineau & Emma LopezProgramme managers at 21, the French Red Cross Social Innovation Accelerator
“Putting the projects supported by the 21 accelerator through Junko’s method gives our laureates the opportunity to question their model afresh and ask the right questions ahead of commercialisation. Thanks to a collaborative approach and concrete expert feedback, our laureates strengthen their value proposition, and ultimately their social impact.”
Julien BourcerieHead of Mobility Engineering, Aximum
“Junko supported us at a pivotal moment for several business units we had just brought together, so that they could jointly find a growth driver to activate quickly. We came out of it with a strong bet on a tactical opportunity that combines the best of these two business units around mobility, digital and road equipment. The deliverable is above all the teams’ commitment to a shared project, and a clear formalisation of the value proposition of this strategic repositioning. I appreciated how on-point the Junko team was: they overlook no detail and build strong alignment, never seeking to please but to find the best path for the company.”
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.”
