I come in as the first or only marketing hire for B2B SaaS startups — Stealth through Series B. I build and execute the GTM strategy that fits your product, your market, and your budget. No generic playbooks. No agency overhead.
I build campaigns, write content, coordinate contractors, and iterate alongside founders. I don't hand off execution to an agency and call it done.
Every startup has a different product, different ICP, and different budget. I don't apply a playbook I used for someone else — I build the one that fits your stage.
You don't have a marketing team. You need someone who can be that team. I come in as the first marketer — PR, demand gen, content, events, and GTM strategy, all under one engagement.
AI infrastructure, enterprise AI, LLM-powered products. I speak fluent technical without dumbing down your positioning.
Connected devices, firmware platforms, B2B hardware-software. Bridging the gap between engineering and the market.
HIPAA-aware products, clinical workflows, digital health. Regulatory-adjacent positioning without the jargon.
No-code tooling, ops software, API-first products. Translating complex integrations into clear buyer value.
"Colleen is a gem of a marketer. Being the first marketer at our startup is not an easy job. Still, Colleen was able to manage multiple initiatives from PR, social media, building out demand gen efforts, to running webinars and organizing in-person events logistics — she did it all."
— Colleague, Petuum
"Her knowledge of marketing tools like Hubspot and Salesforce is unmatched. Companies would be lucky to have Colleen on their team, especially as a manager."
— Colleague, Memfault
"Colleen is very meticulous and detail oriented, making sure things are done properly and with high quality. She genuinely cared about her team and seeing them be successful."
— Colleague, StackIQ
PipelineZero exists for founders who are building something real and need a marketing leader who can operate at the pace of a startup — without the cost or commitment of a full-time CMO. If that's you, let's talk.
