About me

Hi, I’m Stacy Ozier-Lafontaine — but my nickname is "Staceefy".

That nickname was coined by a former sales director who used to call me a “growth machine.” I always had the right tool, the best process, or the most efficient workaround to get things moving. Back then, every SaaS startup /product ended in -ify — so the name stuck.

Today, Staceefy is the version of me that founders, marketers and product teams bring in when they need clarity, momentum and results.

With 10+ years of experience across SaaS, e-commerce, healthcare and B2B services (especially in the French market), I specialize in building growth systems that are strategic, structured and scalable.

I work at the intersection of marketing, product and ops — helping you move from scattered tactics to structured growth. Whether you’re launching your first campaign, connecting your tool stack, or aligning product and marketing, I help you design smarter systems, faster.

Outside of work, I teach part-time, train in Muay Thai 🥊, play piano, and coach young professionals from underserved backgrounds. I like things that require focus, iteration and impact — whether it’s building funnels or throwing kicks.

Her passion for growth marketing combined with her strong technical skills makes her a truly 
T-shaped professional whose services should be taken advantage of. One of the people I've most enjoyed working with throughout my career.
