Founder’s Associate Intern - Growth Office

About bottleplus

bottleplus aims to solve a simple yet significant problem: people drink too little water and consume too much single-use plastic. We have developed a mobile carbonator that makes PET bottles redundant on the go, and we are now taking the next step: Taste. Our products are functional, practical for everyday use, and scalable.

Tasks

We are at a stage where good ideas are no longer enough – clean execution is. Growth at bottleplus means: Influencer Marketing, Go-to-Market, Launches, Processes, Tests. And someone who pitches in where it currently has the greatest leverage. You will work directly with the founders in the Growth Office.

What you will do:

• Influencer Marketing & Operations (≈50%)
  • Research, coordination, campaign support, reporting, structuring processes
• Go-to-Market & Marketing (≈30-40%)
  • Support for launches and growth initiatives for our Taste products
  • Close collaboration with the CMO
• Growth & PR Support (≈10-20%)
  • Research, analyses, external topics where appropriate

In short: You will work on what drives growth this week.

Why this is important for you:

Most internships are observer roles. This one is not. You will be close to real decisions, real numbers, and real execution. You will see how growth really works – not as a case study, but live. You will work with the founders, not for them. When we discuss new launches, influencer strategies, or growth channels, you will be at the table.
