“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.”

Mission

Ector has set itself a mission: to simplify travel to and from airports and train stations by making valet parking accessible to everyone. With revenues of €10 million, 15 hubs in France, a fleet of independent valets, and an API integrated by airports, the startup is entering its third phase of growth: that of a mature tech company.

How Stellar Supported Ector

Audit

Tangible results and a new direction for our technology strategy

Stellar's support helped Ector break out of its technical rut, restore clarity within the management team, and strengthen the position of its CPTO. The result: a relaunched migration, an activated plan, and a more streamlined organization to support growth.

  • A prioritized and validated migration plan: the roadmap has been clarified, sequenced, and endorsed at the strategic level, enabling rapid implementation.
  • A CTO who received support and refocused on his priorities: thanks to mentoring, Simon was able to structure his decision-making process, better defend his decisions, and regain his influence.
  • Clarified Product-Tech governance: everyone's role has been redefined, laying the groundwork for a more robust and scalable target organization.
  • A renewed sense of momentum despite a smaller team: quick wins helped secure the legacy while laying the groundwork for the future: recruitment, delivery, and product vision.
Challenge

From problem to solution: How Ector overcame its challenges

Ector faced a number of challenges that hindered its growth and development. Here's how Stellar helped them overcome these obstacles to accelerate their growth and achieve their goals.

#1 Migration blocked

The tech redesign had been stalled for over a year, with no clear plan or shared priorities

Prioritized and actionable migration plan

A clear plan was jointly developed, approved by the Executive Committee, and implemented as soon as the audit was completed

#2 Tensions between product vision and operational priorities

Without a product manager or product structure, decisions lacked a business framework

Preparing product structure

A dedicated tech/product team has been established to support growth over the next 12 to 24 months.

#3 Isolated technical leadership

Without clear channels of communication or a shared decision-making framework, structural decisions piled up without smooth coordination, slowing down the process of gaining perspective and making long-term progress.

Targeted mentoring

Tailor-made support helped him clarify his priorities, make confident decisions, and better align technology with business challenges.
