Stellar & Ector, a strategic collaboration to lay the tech foundations for long-term growth.
In this assignment, Thibaut Fatus & Antoine Bachès worked alongside Grégory Hachin, CEO at Ector, to secure the technical trajectory and support his CPTO in a context of heavy legacy debt.


Pitch
Ector has set itself a mission: to simplify airport and station journeys by making valet parking accessible to all.
With revenues of €10 million, 15 hubs in France, a fleet of independent valets and an API distributed by airports, the scale-up is entering its third phase of life: that of a mature tech company.
Your growth doesn't rely solely on Marketing and Sales.
A product that doesn't deliver on its promises is doomed to failure, even with the best marketing and sales people:

Concrete results & a realigned tech trajectory
Stellar's support enabled Ector to get out of its technical rut, restore clarity to the management team and strengthen the position of its CPTO. The result: a relaunched migration, an activated plan, and a clearer organization to support growth.
- A prioritized and validated migration plan: the roadmap has been clarified, sequenced and supported at strategic level, enabling rapid implementation.
- A CTO supported and refocused on his priorities: thanks to mentoring, Simon was able to structure his decisions, better defend his decisions and regain impact.
- Clarified Product-Tech governance: everyone's role has been redefined, laying the foundations for a more robust and scalable target organization.
- A renewed dynamic despite a reduced team: quick wins helped secure the legacy while preparing for the future: recruitment, delivery and product vision.
Testimonial
"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."
