Why Conversion Lab Exists
Conversion Lab is a fractional leadership consultancy for businesses ready to turn strategy into results. We bring senior marketing, operations, and accounting leadership to founders and leadership teams who need the experience but not the full-time payroll.
From high-level strategy to hands-on execution, we align your marketing, your operations, and your numbers around your specific business goals, because the problem is rarely where it first shows up.
Led by Carrie Nielsen, Conversion Lab brings structure, speed, and accountability to every engagement, without the overhead of an in-house team.
We believe smart systems, clear messaging, clean numbers, and fast execution are the real growth levers, and we build every engagement to reflect that.

Carrie Nielsen, Founder
Fractional CMO | Operator | Systems Builder
Carrie Nielsen is a seasoned marketing leader with two decades of experience in brand, growth, and performance marketing. She’s worked inside billion-dollar brands, franchise systems, and growth-stage companies — bringing structure, speed, and clarity to marketing teams navigating complexity.
She launched Conversion Lab as a modern solution for businesses seeking senior-level strategy without the overhead of a traditional agency or internal marketing team. Her background spans paid media, full-funnel design, CRM and RevOps, creative messaging, and franchise sales enablement — all centered around one core belief:
Marketing should be accountable to business outcomes.
Today, Conversion Lab partners with founders, lean teams, and revenue leaders to identify friction, sharpen strategy, and build high-performing systems that convert.
Carrie works solo or in collaboration with a trusted bench of media buyers, analytics pros, and creative partners — scaling the right support when and where it’s needed.
Beyond marketing, Carrie co-owns and operates multiple companies with her husband, spanning commercial services, security, and property. That day-to-day ownership is where the operations and accounting practice comes from: real payroll, real cash flow, real hiring, real lenders. She has sat on the owner's side of the table, and it shows in the work.

Our Philosophy
Most teams aren't short on ideas. They're short on systems.
Conversion Lab exists to bridge that gap by diagnosing what's broken, prescribing a strategy that fits the business, and building a structure that's made to perform, whether the gap is in marketing, operations, or the numbers.
Every engagement is grounded in The Lab Method, a structured, test-and-learn approach to uncovering what works and scaling it with purpose. We work with internal teams, trusted vendors, and proven platforms to execute quickly, track what matters, and eliminate the waste that slows growth.
What We Believe
-
Strategy should serve business goals — not just brand decks
-
Funnels should convert, not just collect leads
-
Messaging should speak to humans, not just algorithms
-
Execution should be fast, focused, and accountable
-
Marketing, operations, and finance are one system. Fix them together or fix nothing.
We’re not a full-service agency. We’re the strategic partner you call when you’re serious about fixing what’s broken and scaling what works.
