Fractional CMO · B2C Marketing Leadership
Stop paying agencies for execution without strategy. One Source brings senior marketing leadership to B2C companies ready to scale — without the $200K+ full-time hire.
Client performance snapshot
How it works
We don't need a 90-day onboarding period. We audit, align, and execute — fast.
We audit your current channels, spend, and conversion points. You'll know exactly what's working, what's broken, and what the biggest opportunities are — before you spend a dollar.
We build a 90-day marketing roadmap tailored to your revenue goals, competitive landscape, and budget. Board-ready, team-executable, and built to measure.
We manage your team, vendors, and campaigns with weekly check-ins and monthly reporting. You get a fractional CMO who answers to the numbers — not just the hours.
Who we help
We work with businesses that have marketing spend to manage but no senior strategist in the room. If you've outgrown your last agency and need someone who thinks like an owner — this is for you.

Client results
Replace these with your actual client testimonials — these are placeholders to show the structure.
"One Source cut our Google Ads cost per lead in half within 60 days. Erik doesn't just manage campaigns — he thinks like an owner. It's like having a VP of Marketing without the overhead."
"We went from guessing at our marketing to having a real strategy with clear KPIs. Our Meta leads are up nearly 4x and the quality has actually improved. Best investment we've made."
"Our PE sponsor wanted marketing accountability we couldn't deliver internally. Erik stepped in, built a reporting structure, and had our ROAS up within the first quarter. He speaks the language."

Common questions
The questions we hear on every first call — answered upfront.
What's the difference between a fractional CMO and a marketing agency?
Agencies execute campaigns. A fractional CMO owns your marketing strategy, manages your vendors, aligns your team, and reports to you as a senior leader — not as a vendor pitching their own services.
How quickly will we see results?
Most clients see measurable CPL improvements within 60–90 days. The audit and strategy are delivered in week one. We don't believe in 6-month onboarding periods before we start moving the needle.
Do you work with our existing agencies and team?
Yes — we work alongside your current vendors and internal team as the strategic layer above them. We manage them, hold them accountable, and eliminate the wasted spend that comes from no one owning the big picture.
What industries do you specialize in?
We focus exclusively on B2C — home services, local service businesses, e-commerce, and multi-location operators. We don't do B2B SaaS. We know B2C lead generation and customer acquisition deeply.
What does the retainer include?
Strategy development, weekly check-ins, monthly reporting, paid media oversight, vendor management, and direct Slack/email access. You're getting a senior marketing executive — not an account manager.
Is there a minimum commitment?
We ask for a 3-month initial engagement so we can deliver real results. After that, engagements are month-to-month. We don't believe in locking clients into long contracts — we earn retention through performance.
Book a strategy call
Pick a time that works for you. We'll spend 30 minutes auditing your current marketing, identifying the biggest opportunities, and telling you exactly what we'd do differently — no pitch, no pressure.
