About Us

Upsell is an early-stage, data-driven startup on a mission to help businesses sell smarter.

We use AI to deliver personalized sales recommendations at exactly the right time—based on real signals like company growth, new hires, or leadership changes.

Instead of sending more emails, we help sales teams send the right message, to the right company, at the right moment.

We’re building the leading sales intelligence platform in the DACH region and the US—and we’re just getting started.

Our Mission

We aim to become the go-to platform for sales intelligence and customer retention in B2B.

With a focus on timing, personalization, and automation, we help companies grow faster and waste less time on generic outreach.

We're looking for an energetic and curious B2B Sales Representative to join our startup on a part-time basis (ideal for students). This role combines sales, marketing, and client interaction in one.

You’ll help us:

• Generate leads using LinkedIn, email tools, and our own platform
• Write personalized messages and outreach campaigns
• Create basic marketing content (posts, short emails, slides)
• Organize and conduct online and in-person meetings with prospects
• Attend conferences, startup expos, and networking events to represent Upsell
• Learn how AI is shaping the future of B2B sales

• Strong communication skills – written and spoken
• Interest in tech, sales, or startup culture
• Self-driven and willing to learn fast
• Comfortable talking to clients both online and in real life
• Fluent German speaker, advanced in English
• Enrolled in or recently graduated ideally from business, economics, or marketing-related programs

• Flexible working hours – easy to combine with studies
• Real-world startup experience
• A chance to learn AI tools, CRM systems, and B2B outreach
• Be part of a growing startup from the ground up
