About Stellar
Four studios, one system, one person to call.
John Markadakis came up in the trades — a machinist and a performance automotive technician who built 1,500-horsepower GT-Rs, then a stint in industrial sales moving forklift batteries to plants and warehouses — before he ever picked up a camera. He started Stellar Media Collective after watching premium home and trade businesses do exceptional work that was completely invisible online. The gap between real-world quality and digital presentation was costing them clients, margin, and growth — and nobody was solving the whole problem at once.
The turning point came in an unlikely place — the professional speaking and personal-development world. For years John filmed some of the highest-paid presenters alive: people whose entire livelihood is how they present themselves. His job was to listen to brilliant, highly educated experts and figure out how to make a room choose them — pure conversion work. It worked. He helped speakers land $40,000 engagements.
That’s a different craft than filming. Most videographers point a camera and hope; John had learned to engineer what actually makes someone choose — in the one industry where presentation is the product. Pair that with the visual discipline of high-end real estate, bring it to trades doing $80,000 work that looks like $8,000 online, and you get the whole Stellar approach: the conversion instinct of the speaking world, the craft of real estate, and the credibility of someone who’s actually worked on the tools. Most videographers can’t think strategically; most consultants can’t film. John does both.

“Video is how people see our work, and our clients’ work. The work itself is bigger: fixing the problems a business has been fighting for years, sometimes decades, so it gets simpler, lasts, and scales.”

The Background
The thinking behind the work.
What ties that path together is an obsession with how premium buyers actually decide — sales psychology, brand narrative, offer design — ideas John studied for years and built into how Stellar presents every client. Most marketing treats the film, the website, and the ads as three separate jobs; he’s watched a great film fail to rescue a weak story, and a sharp message die on a site that looks like everyone else’s. So Stellar runs them as one system, and the system reaches further than the marketing: the leads, the dashboard, the data and the way the office runs. He gets your world because he’s worked in it — and he knows how to make a premium buyer choose you.
The bench
John runs it. These are the people he runs it with.
We're a collective by design — four independent studios working as one team. You sign one agreement and you talk to one person. And because each of us runs our own shop, the person doing your work is the one answerable for it.

Stellar Media Collective
Came up in the trades — a machinist and performance automotive technician who built 1,500-horsepower GT-Rs, then a stint in industrial sales moving forklift batteries to plants and warehouses, all before he ever picked up a camera.
Spent years filming professional speakers and experts — people whose entire livelihood is how they present themselves. That work is pure conversion: listen to someone brilliant, then figure out how to make a room choose them. He helped speakers land $40,000 engagements doing it.
Started Stellar after watching premium home and trade businesses do exceptional work that was completely invisible online. The work has grown past the camera: the lead system, the dashboard, the data and the processes underneath a business, built so it gets simpler, lasts and scales. On every shoot, and the person you talk to.

Dinko Design
Ten years building websites, the last of them moving off page builders and into custom work clients own outright — code, hosting and all, portable to anywhere.
Builds the same back-office systems for home builders and developers today: the record of every unit and job, the lead routing, the reporting an investor actually asks for.
Also the reason the search side works. The pages get written for the words buyers really type, and for the places you actually build.

Renders and films a building before it exists, so units can be reserved while the site is still being cleared — the presale campaign is the product, not a by-product.
Also works on community branding, and on furnishing and installing the spaces once they're real.
Who we work with
We go deep, not wide.
Developers, commercial builders and construction companies with real work to sell — and the custom builders and premium trades we started with. John is on every shoot and reviews every audit personally, and we're picky about fit: people proud of the craft, willing to show up on camera, who want a team that stays rather than a vendor who vanishes after the invoice. If you compete on being the cheapest, we're honestly not your people.
