Sulitest is a growing organization, supporting universities and business schools worldwide to advance sustainability education. Our flagship tool, TASK™ (The Assessment of Sustainability Knowledge) is the first internationally recognized certificate on sustainability knowledge (the equivalent of the TOEIC for sustainability). As of today, 100 higher education institutions use TASK™ and over 100,000 students have completed the assessment.

The Sulitest movement is strongly supported by major national and international NGOs and organizations (i.e. the United Nations and the Higher Education Sustainability Initiative (HESI)) and has raised 1.5M€+ in 2022.

We are looking for a Business Developer intern to support the development of our sales activities and deploy TASK™ within Higher Education Institutions worldwide.

RESPONSIBILITIES

As part of the Sales & Marketing team, the Business Developer intern role is central to the acquisition strategy, by providing direct support to the Business Developer. Their role is to organize and prepare prospecting activities so that the Business Developer can focus on high-value interactions. In other words, your responsibilities include:

1. PROSPECTION SUPPORT (50%)

  • Identify and qualify target accounts based on the Ideal Customer Profile (ICP) defined with the sales team
  • Leverage prospection list from the Marketing activities
  • Enrich prospect data: key contacts, organizational charts, contact information, buying signals
  • Prepare summary sheets for each account: news, industry trends, decision-making context
  • Draft LinkedIn messages and prospecting emails
  • Make follow-up calls and emails to schedule business meetings

2. CRM MANAGEMENT (30%)

  • Update the CRM after every sales interaction and indicate the next step
  • Track the progress of deals and notify the sales team when follow-ups are needed
  • Ensure data integrity: remove duplicates, fill in missing fields, and update outdated statuses

3. MONITORING, RESEARCH AND IMPROVEMENT (20%)

  • Conduct monthly monitoring of target sectors and share relevant insights
  • Research information useful for tailoring sales approaches
  • Contribute to the continuous improvement of prospecting & growth workflows
  • Contribute to pitch deck development and updates

This internship is ideal for someone who wants to understand the inner workings of a B2B sales strategy, make a tangible contribution to the growth of an impact-driven organization, and develop strong practical sales skills.

Our aim: by the end of this internship, you’ll have all the skills you need to identify relevant prospects, contact them via the most appropriate channel, secure a meeting and send them the proposal best suited to their needs.

This internship offers the opportunity to transition into a permanent position (CDI, Contrat à Durée Indéterminée) at Sulitest upon completion, depending on performance and mutual interest.
