MarketKing was built by a contractor who got tired of watching good businesses bleed money into marketing that couldn't prove its worth. We fix that — with data, automation, and a system built for real revenue growth.

Before MarketKing was an agency, it was a problem — a problem Max Sereda couldn't stop thinking about.
Most marketing agencies were built by people who have only ever been marketers. MarketKing was built by someone who was also a business owner — and knows what it actually costs when the phone goes quiet.
Max Sereda spent 11 years building, operating, and eventually selling his own HVAC & Plumbing company in Chicago — growing it from a single van to $5M+ in annual revenue.
He ran the ads, chased the leads, and learned — the hard way — what actually moves the needle versus what just moves money out of your account.
He saw the same pattern everywhere: business owners spending thousands on agencies that reported on impressions and clicks, while the phone stayed quiet and the pipeline stayed empty.
So he built something different. Not another ad agency. A performance engine — built around one obsession: connecting every dollar of ad spend to real, trackable revenue.
Today, MarketKing manages $10M+ in ad spend, has driven $100M+ in tracked client revenue, and works with service businesses, franchises, SaaS companies, and high-ticket brands across the U.S. — all through the same system: data, automation, full-funnel control, and zero tolerance for vanity metrics.

Here are the non-negotiables we build every client system around.
If you can't prove which campaign made you money, you're guessing. We build the tracking layer before we touch the ad account.
Most businesses lose 50–70% of their leads to slow response and manual chaos. Automation isn't optional — it's the difference between a pipeline and a leak.
CTR, CPM, impressions — none of it pays your bills. We optimize toward one thing: measurable cash flow tied to real ad spend.
One good month doesn't build a business. A system that improves weekly, tests relentlessly, and scales what works creates predictable growth.
We've run businesses. We know what it feels like when the phone stops ringing. That's why we show up like owners — not vendors.
SEO, PPC, Email, CRM, CRO — none of it works in isolation. We build everything around one dashboard, one truth, one scoreboard: profit.
Here’s what actually separates MarketKing from typical marketing agencies.
