Most agencies are broken.
They charge clients a fee, outsource the work to unknown vendors, and hide behind buzzwords. There’s no accountability, no standard of execution, and no pathway for young marketers to grow real skills.
Dennis Yu saw this problem 15 years ago and began building something different—a two-sided network designed to help local service businesses grow while training the next generation of digital marketers.
This is a repeatable system that’s been battle-tested with clients like Roger Wakefield (plumber), Dr. Glenn Vo (dentist), and big brands like Nike and the Golden State Warriors.
While Dennis was in Minnesota filming with Jack Wendt and Dylan Haugen for the AI Apprenticeship Program, he sat down with Dylan, Jack, and Henry Holm to explain exactly how the two-sided network works—drawing it out on paper and walking through each piece of the system.

What Is a Two-Sided Network?
Most companies operate a one-sided model: they sell a service and get paid. Done.
A two-sided network, on the other hand, connects two interdependent groups: in our case, local service businesses and certified digital marketing apprentices. BlitzMetrics sits in the middle.
Think Uber:
- Riders want a ride.
- Drivers want passengers.
- Uber connects both.
Now imagine Uber, but for local businesses needing marketing and young adults needing experience. That’s BlitzMetrics—with one major difference.
Uber drivers earn a flat fee per ride. They don’t grow new skills. They don’t move up. Once you’re a driver, that’s it.
BlitzMetrics apprentices, on the other hand, are gaining certifications, building real-life skills, and developing leadership. They can advance, take on more responsibility, and get paid more as they deliver more value. This is a true career path.
The key to making this work? Trust, training, certification, and documented results.
The Demand Side: Local Service Businesses
Our Ideal Client Profile (ICP) is a local business in a high-ticket, Google Local Service Ads (LSA) category:
- Dentists
- HVAC
- Roofers
- Electricians
- Real estate agents
These are $2,000–$20,000 jobs. That’s why the ROI from digital marketing matters.
Why LSA?
- It’s Google-certified and highly trackable.
- It mirrors professional licensing (Google only allows licensed pros).
- Every city has thousands of identical businesses.
- What works for one plumber in Dallas works for dozens more nationwide.
We’ve created systems that let us clone success stories across cities and verticals. This includes our geo-vertical grid approach and our reusable Content Factory.
The Supply Side: Certified AI Apprentices
On the other side, we train and certify apprentices in our systems:
- Content Factory
- Social Amplification Engine
- Digital Plumbing
- MAA (Metrics, Analysis, Action)
- The 9 Triangles (our foundational framework that connects all pieces of the system)
Before they ever touch client work, they:
- Watch training.
- Do it themselves.
- Teach others.
This system honors LDT (Learn, Do, Teach), ensuring that apprentices are applying what they learn and developing the ability to mentor others.
This is how myself (Dylan Haugen), Henry, and many others have built real-world experience while gaining income and opportunities.
No AI-generated resume or fake certificate here. Every apprentice must:
- Make 1-minute videos
- Repurpose existing long-form content into blog posts
- Complete live audits and submit weekly MAA updates
These expectations ensure each apprentice demonstrates applied skill, communication ability, and consistent accountability.

How It Works: The Core Systems
1. Emergency Room Intake
When a new client comes in, they’re in pain.
So we:
- Run a $297 Quick Audit
- Diagnose with Digital Plumbing and MAA
- Prescribe the right package
- Connect the business with a certified AI apprentice who will execute the strategy and walk them through the next steps outlined in Digital Plumbing, Content Factory, and MAA
This process gives us the clarity to define where a business truly stands, what’s missing, and what actions will have the most impact moving forward.
2. Digital Plumbing
The foundation. Without tracking in place, we have no data. And without data, our marketing efforts simply can’t succeed. You need to learn from the data to improve and scale results.
Digital Plumbing makes sure we know:
- Where leads come from
- Which channels are converting
- What’s driving ROI
Every performance-driven business client we’ve worked with has said: “Digital Plumbing is the most valuable thing you’ve built.”
3. Content Factory
The Content Factory is a 4-stage process designed to help you become visible on Google by leveraging AI tools and maximizing the use of your best content across various platforms.
- Produce: Capture content that proves you do what you say you do—photos, videos, Zooms, podcasts, speaking engagements, and more.
- Process: Use tools like Descript and ChatGPT to transform raw content into polished blog posts, web pages, and other assets that reflect Google’s E-E-A-T standards.
- Post: Publish this content across your website, social channels, and more to maximize visibility.
- Promote: Amplify your content with Dollar-a-Day ads and other tools that drive targeted attention to what’s already working.
We reskin this across verticals. The content might look different for a dentist than a roofer, but the system never changes.
4. MAA: Metrics, Analysis, Action
Every week, apprentices submit their MAA.
- Metrics: Pull the numbers
- Analysis: What do the numbers mean?
- Action: What are you going to do about it next week or in the upcoming weeks?
Most people fail at step 2. They paste in numbers but offer no insight.
Weekly MAA creates momentum. Without it, progress stalls. With it, we can iterate and win.
The Lighthouse Effect: Why This Scales
Roger Wakefield is the #1 plumber influencer in America. We helped him grow, documented every step, and used that as a lighthouse.
Other plumbers said, “I want what Roger has.”
Same with Dr. Glenn Vo, Tommy Mello, Sal Sciorta, and others.
Once you win with a lighthouse, everyone in that vertical follows. The more examples, the more powerful the network.
We package these examples into books, landing pages, ad campaigns, and training. Every new client or apprentice sees a clear path to success.
Why Agencies Are Dead
The traditional agency model is a waiter selling services from a menu. But the agency doesn’t cook.
Most agencies:
- Subcontract the work for $100/month to white-label vendors overseas
- Fake results with automated reports
- Hire untrained virtual assistants
BlitzMetrics does the work in-house. Our certified apprentices execute with supervision. We measure results and iterate weekly.
This is why major organizations—from Johns Hopkins University to respected leaders across local service communities—come to us.
What Local Businesses Pay For
For local businesses doing $2M+/year, we recommend our Conversion Engine ($3,500/month, plus ad spend)
That’s still under 10% of their gross marketing budget.
We also offer:
- Knowledge Panel package: Build your reputation and achieve a Google Knowledge Panel
- One-time audits: Diagnose the issues
What Apprentices Pay For
For those looking to join the AI Apprenticeship Program:
- AI Apprentice certification: $1,997–$2,497 for young adults, often paid by parents or business owners
- Apprentices can also self-qualify through our internal hiring and onboarding process.
Each side pays based on what they need:
- Businesses pay for growth
- Apprentices pay for mentorship and career opportunity
And it’s all based on performance.
Why This Works
- Repeatable process across all verticals
- Real certification
- Transparent tracking
- Weekly accountability
- Dozens of lighthouse examples
Every part of the BlitzMetrics model is built on documented process and repeatable systems. Apprentices build their skills by working on real campaigns with oversight. Clients see measurable results because we apply proven strategies, track performance, and adjust based on data.
This is how Dennis Yu’s two-sided network vision becomes reality—reliable, scalable, and proven through systems that actually deliver.
