Context
Léon Event is a corporate event agency in Annecy. As event project assistant, I supported the project manager across the full cycle — from client brief to signed proposal — on seminars, corporate parties and incentives.
Confidentiality: client names are never shown. Figures and examples will be added once verified for public sharing — described only by type and range.
My role
I worked alongside the project manager, turning client briefs into structured, comparable, decision-ready proposals.
What I did
- Took client briefs and translated them into sourcing requirements.
- Sourced venues, hotels, activities and suppliers to match each brief.
- Built cost / capacity / logistics comparisons to guide the choice.
- Assembled proposal decks and integrated client feedback through to signature.
What the job taught me
An agency sells expertise, not just suppliers
I hadn't understood that agencies apply a margin on the services they resell. It reframed how I read a proposal: every line has to justify itself to the client, because the client is paying for the selection and the coordination, not only for the venue.
Nothing goes out without sign-off
Every proposal is validated by the project manager and the director before it reaches the client. I learned to build a deck that can be reviewed quickly — comparable options, explicit assumptions, no gaps for someone else to fill in.
Sourcing runs on follow-up
Suppliers don't answer first time, even when there's money on the table. Chasing is not a failure of the process, it is the process. I also learned to work around local habits — you don't call Spain in the early afternoon and expect an answer.
A plan B is a document, not an intention
I knew the principle; I learned the practice. A fallback only counts if it is costed, sourced and ready to be swapped in — otherwise it is just a sentence in a meeting.

What I took away
Sourcing is a decision-support job: the value isn't just finding options, it's laying them out so a client can choose with confidence. I got faster at spotting what really separates two venues on cost, capacity and logistics.
