About Guillaume

I help sales managers make their salespeople autonomous and performant 2 to 4 times faster than usual — and keep them.

After 10 years in business development and managing sales teams (IT service companies, IT consulting, hyper-growth startups), including a Sales Director position, I address the real bottleneck for sales teams: the long ramp-up time and profile turnover.

My approach is not a one-size-fits-all recipe. I start with your management's objectives and each salesperson's specific working method, then I build a tailored organizational framework: prioritization, task management, cascading objectives (quarterly down to daily), and work autonomy.

Some results achieved:

- A profile with no prior sales experience became profitable in the 1st month (norm: 3 months)
- A recent graduate at 120-130% of their objectives after 1 year, still in the role 4 years later
- A team whose turnover decreased by 60% after management redesign

What you gain: several months of advanced revenue, freed-up management time, and salespeople who stay — each departure avoided saves 6 to 12 months of salary.

I work in 4 formats: sales audit, group training, individual coaching, or integrated program.

I target B2B sales teams in startups, scale-ups, and mid-market companies — growth structures where the sales organization is still to be built.
