Job description

🚀 Greenzy is recruiting a Sales/Business Development Intern (B2B) – Brussels (GreenBizz)

At Greenzy, we help companies take action in the office with a concrete solution for managing bio-waste simply (and getting teams on board in the process).

We are already prospecting today... but we need more firepower to generate more results.

🎯 Your main mission: to boost our B2B sales

You will help us to:

• Find leads (research, targeting, qualification)
• Contacting and calling prospects (initial contact, follow-ups)
• Convincing prospects with a clear, needs-oriented pitch
• Reporting back on feedback from the field to improve our sales approach
• Depending on the time of year, you may also be able to help with follow-up and customer relations for composters that have already been delivered.

👀 What we are looking for

• Bachelor's/Master's student
• Minimum 3-month internship
• Comfortable on the phone, driven, persistent
• Curious, proactive, with a real desire to learn
• You enjoy the ‘test/measure/iterate’ challenge

🔥 Why join us

2026 is coming with a lot of challenges: we need good figures for our next fundraising campaign. So things are going to be busy, and you will be at the heart of the sales machine, supported by the team.

📍 Where? GreenBizz – Brussels (great ecosystem, events, meetings, good dynamic)

💡 Unpaid internship (Erasmus+ grant possible for non-Belgian students)

📩 To apply

Send your CV + cover letter + internship period and duration to job@greenzy.be
