Hi! I'm Justine
I’m Justine, a Fractional CMO and Founding Marketer. I work with startups, SMBs and nonprofits that need marketing leadership but aren’t ready for a full-time hire. I build their first growth engine, simplify messy MarTech stacks, and use AI to make teams smarter and leaner. Beyond client work, I’m building Seedli, a studio of services, products, and resources for marketers working at the intersection of growth, tech, and climate.

MarTech
MarTech
MarTech Systems Builder I help you build and optimize a modern, efficient marketing stack tailored to your current stage and future growth. Whether you're choosing your first CRM or automating multi-channel campaigns, we start with strategy and scale from there.
Audit
I review your current stack or tool usage, identify what to keep, optimize, or replace, and deliver a written action plan with a recommended implementation path.
→ Pricing: €2500
Recommended implementation path
Based on the audit, I recommend the best-fit execution model:
→ You Implement: You take the audit + action plan and execute with your own team. You already have trusted internal resources.
→ Done With You: I guide implementation and stay involved to ensure quality. You want support but retain ownership.
→ Matchmaking: I introduce you to a vetted expert from my network to implement the plan. You need help but I’m not the best person to execute.
→ Squad Assembly: I build and lead a small team to deliver the full stack implementation. You need a turnkey solution.
Pricing: On demand (based on complexity and project scope)

Tools
My toolbox
I love martech, and tech in general. I’ve tested well over 100 tools and have done full-stack setups from scratch more times than I can count. I’m not interested in tech for the sake of it. I look for tools that support people, streamline processes, and eliminate repetitive tasks so teams can focus on what matters.
