Meaningful connections. Projects moving forward.
The right connections
for your technology priorities.
By Celestia connects business decision-makers with selected technology partners. We start with your priorities, prepare relevant meetings and help identify the next steps.
Relevance before volume.
For decision-makers
Your priorities deserve the right people.
Transformation, innovation, AI, data or information systems: clarify your questions and meet the expertise that can inform your decisions.
- Understand your context, constraints and project maturity.
- Select relevant expertise and prepare each conversation.
- Identify useful insights and agree on appropriate next steps.
You remain in control of your decisions and of the relationships you wish to pursue.
For technology partners
The right company. The right context.
Present your expertise to decision-makers for whom it can address a real need. We start by understanding your use cases, references and deployment conditions.
- Define the target context and the purpose of the relationship.
- Choose the right format: introductions, meetings or events.
- Follow the relevance of the conversations and agreed next steps.
Meeting or sales volumes are not guaranteed unless specifically agreed.
A clear framework from the start.
How we work
By Celestia may be paid by a technology partner and/or for an agreed advisory service. Each party’s role and the applicable terms are clarified before any commitment.
The information needed for an introduction and its intended recipients are agreed with you. An initial enquiry does not authorise general circulation of your contact details.
Formats shaped around your needs
Targeted introductions, peer discussions, conferences, trade shows or dinners: the format follows the objective. Preparation and follow-up matter as much as the meeting itself.
President of By Celestia
Jimmy Bideault
With a background in digital services, Jimmy Bideault develops By Celestia to connect business priorities with relevant technology expertise.
The approach first took shape around technology trade shows. Today it also encompasses targeted introductions, peer discussions and events that help move a project or a strategic conversation forward.
Listening, careful selection, clarity of roles and attention to follow-up guide the way we work.

Discuss a tailored journeyVivaTech 2026 has ended. This video showcases a past experience; enquiries concern future projects.
Five ways to prepare better technology meetings.
- Set a clear purpose. Define two or three questions and the decision you want to inform.
- Qualify each meeting. Check the person’s role, expertise and shared objective before filling your agenda.
- Look beyond the demonstration. Ask about integration, deployment conditions, limits and comparable references.
- Capture what matters. Keep concise notes on insights, open questions and relevant stakeholders.
- Agree on the next step. Identify an owner and timing, or clearly conclude that no follow-up is needed.
Let’s start with your context.
