Context
The relationship between Forvis Mazars and Comet is not new: it all began on July 6, 2018. Since then, the international audit, tax and advisory group has made Comet a regular partner for its key collective events.
Within this trusted partnership, Forvis Mazars chose to launch its very first MixiDay, a day dedicated to diversity, and entrusted its organization to Comet Bourse.
The client's brief
“Find a central, informal venue to bring teams together for our first MixiDay.”
Mazars was looking for a setting that could host 160 people in the heart of Paris, with an atmosphere that was both professional and friendly — a place that would embody the spirit of the day without making it feel rigid.
The challenges
- Raise team awareness about gender diversity
- Share moments of work and togetherness
- Having a free mind, without worrying about the technical side
Comet's answer
Comet Bourse, a central and welcoming venue, hosted the 160 team members for a full day. The format alternated between plenary sessions in the auditorium and workshops, punctuated by a standing lunch cocktail and then an afterwork event to keep conversations going.
The key objective: allow Forvis Mazars to focus on content and diversity, while Comet handled all logistics and technical aspects.
Delivery
The day was structured around a key plenary session, followed by workshops that encouraged everyone’s participation. The auditorium and its seats hosted the various talks, while the adjoining spaces set the tone for convivial moments (cocktail lunch, afterwork).
The Comet team provided constant availability and support from start to finish, ensuring flawless execution.
The results
Key takeaways
A successful internal event depends as much on its content as on the peace of mind in its execution. By relieving Forvis Mazars of any technical concerns, Comet enabled the teams to focus fully on the topic of the day.
The depth of the relationship—108 events and over 5,000 people hosted since 2018—confirms that a trusted partnership is built over time.
