About Abel

General Management Consultant | Transition Management | B2B Commercial Development

Are you the leader of an SME or mid-cap company looking to accelerate your growth, improve your sales performance, structure your organization, or drive strategic transformation?

I support leaders facing challenges in development, profitability, organization, and leadership. My involvement provides a fresh perspective on key decisions, aligns teams with company priorities, and turns ambitions into concrete results.

What sets me apart: I don't come from consulting, but from the business world. With over 25 years of experience in General Management, Sales Management, and managing industrial Business Units, I have managed P&Ls, developed B2B activities, led multi-site teams, and driven operational transformations in demanding environments. My approach combines strategic vision, on-the-ground pragmatism, and a results-oriented culture.

I primarily focus on the following projects:

• Part-time General Management
• Transition Management (General Manager, Sales Director, Business Unit Manager)
• B2B Commercial Development and Key Accounts
• Development and deployment of growth plans
• Structuring organizations and processes
• Support for Management Committees and leadership teams
• Optimization of operational performance and KPIs
• Leadership, management, and executive coaching

Preferred sectors: industry, packaging, manufacturing, B2B services, SMEs, and mid-cap companies.

My goal: to help you make the right decisions, mobilize your teams, and achieve sustainable results.
