Growth Marketer, Collie (B2B SaaS) | Part-time

About Collectmaxx

Collectmaxx is a B2B SaaS platform helping companies across Europe automate and optimize their invoice collection and accounts receivable processes. Last year we collected over €65 million for our clients. We are now taking Collie, our new self-service SaaS product, to market and need a hands-on B2B SaaS marketer to build traction for it. We are a small, ambitious team: short lines, real ownership, no layers. We start with Benelux and DACH.

Our new SaaS solution: Collectmaxx Collie

Collectmaxx Collie is a Software-as-a-Service platform built for companies that invoice consumers directly: utilities, insurers, subscription businesses, and service providers. It automates the full invoice reminder and early collection workflow, combining multiple outreach channels with intelligent AI-driven communication flows, before overdue invoices become a collection problem.

Key capabilities:

• Multi-channel outreach: email, SMS, AI Voice calls, and video reminders, fully automated
• AI-generated communication flows: smart sequences that adapt tone, timing, and channel based on consumer behavior
• Installment plans: built-in, configurable payment arrangements to recover more without escalating to collections
• EU-wide payment links: Paylink support covering local payment methods across EU markets
• White-label ready: businesses deploy under their own brand, preserving customer relationships
• Self-service portal & dashboard: consumers manage their own invoices; clients get full visibility on performance

Collie is priced as a subscription with no large upfront commitments, purpose-built for SMEs and mid-market companies ready to move to a SaaS model.
