Internship Inbound & Outbound Sales at Startup centre

Are you ready to kickstart your career with a fast-growing company that's revolutionizing the merchandise industry? Join our dynamic team at Monday Merch and embark on an exciting journey where you'll learn, grow, and make a real impact.

Monday Merch is a leading merchandising company dedicated to delivering high-quality, customizable merchandise solutions. With our innovative approach and commitment to excellence, we're expanding our global presence and setting new standards in the industry.

You'll play a vital role in helping some of the coolest brands in Europe bring their merchandising visions to life. This internship offers a unique blend of project management, sales and creative thinking.

As an Inbound & Outbound Sales Intern at Monday Merch, you’ll work closely with two teams - Qualifying/Sales and Outbound. Regarding the qualifying team, you will support the first stage of our sales process by qualifying inbound leads through reviewing incoming requests, understanding customer needs, and identifying strong opportunities for the Sales team. You’ll also manage merch projects ranging from 3,000 to 100,000 euros.

At the same time, you’ll support outbound sales by researching promising companies, preparing target lists, reaching out to potential B2B customers and developing materials for more effective follow ups (e.g. merch concepts, guides).

In other words, if you are a well-rounded person who wants to explore multiple fields during one internship (not on a surface level) - this is a great opportunity.
