A developer-tools video agency run by editors who write code.

Not a dev-tools division. Developer tools are the whole company.

// what we do

Lumaris is a video agency built only for developer-tools companies.

Editors who write code produce tutorials, demos, launch videos, and conference content checked line by line, delivered in about five days, with 95 to 99 percent intro retention on the developer channels it cuts, labeled creator-channel. From one video at €2,000 to the full function on a retainer.

// who this is for

Most agencies that say they do tech video mean they once cut a SaaS explainer. Developer tools are different. The buyer is an engineer, the product is the command line and the API, and the fastest way to lose the room is a video that gets a detail wrong.

We do not have a developer-tools division. Developer tools are the entire company. That focus is why the work lands with the audience that decides what their company adopts.

// the case

The questions you're weighing.

Generalist agencies do not survive a developer audience.

Developers grade whether the commands work, not the production gloss. A generalist agency ships work that is almost right, and engineers enjoy pointing that out, publicly.

What kind of video do developer-tools companies need?

Product and API demos, tutorial series, launch videos, conference talk edits, and the explainer that finally makes the architecture click. Across all of it, the constant is a technical audience that will not forgive an error and will not finish a boring video.

We cover the whole arm under one retainer, so the channel reads as one voice and the strategy compounds instead of resetting with every freelancer.

How does Lumaris keep developer-tools video accurate?

Editors who write code, plus an in-house dev team that checks every command, API reference, and diagram against current documentation. Each delivery carries a Dev Validation Receipt naming what was verified. Across 200-plus videos that is zero syntax errors and one to two revision rounds, against an industry four to six.

The retention and click-through figures we cite, 95 to 99 percent intro retention and 13.4 percent sponsored click-through, are measured on the creator channels we cut, whose developer audience matches the audience our buyers want. We label them as creator-channel data every time.

// dev-validation

Your engineers review nothing.

Editors who write production code cut the work, and every command on screen clears a line-by-line check before you ever see it. The accuracy is handled before the review loop starts, so the draft lands right the first time.

  • Commands run against current docs
  • A receipt names what was verified
  • 1 to 2 revision rounds, not 4 to 6

// build vs buy

What it costs.

The front door is one video from €2,000, a complete purchase you keep. The retainer, from €6,000 a month, is the upgrade once the work earns it, never the gate. We frame cost one way only: build versus buy, never a vendor price match.

FAQ

Developer-tools video agency, in short.

What makes a video agency right for developer tools?

Editors who have shipped production code, and a check on every command before you see the cut. A developer audience grades whether the commands work, not the gloss, so the only agency that survives is one that can read the terminal and get it right. That is the entire company here.

Do you work outside developer tools?

No. The focus is the product. Developer tools, DevOps, and AI infrastructure are the whole company, and that is why the work lands with an audience that discounts generic marketing on contact. A generalist who also dabbles in dev tools is exactly what we are built not to be.

What does an engagement look like?

Start with one video at €2,000, a complete purchase you keep. When it earns it, one scoped retainer from €6,000 a month covers the whole video arm: tutorials, demos, launches, and conference content, with a five-day first draft. We cap the retainer at ten clients so the standard holds. Most teams start with a free spec edit on a video they already published.
