Services for developer tools companies
Your developer audience grades one thing: do the commands work.
We produce video for developer tools, DevOps, AI infrastructure, and developer-facing security. Nothing else. Every editor has shipped production code. Every draft is validated by an in-house dev team. The first draft is the real draft, every time, because the people making it understand what they're making. We call this the First-Draft Standard.
Before we talk about what Lumaris costs
Look at what your current process is already costing.
hidden-costs.log
// Monthly cost - generic agency baseline4-6 hrs brief preparation (marketing time)6-10 hrs engineering review of draft 01 (€60-120/hour loaded)3-5 hrs correction explanation back to editor4-8 hrs engineering review of draft 022-4 hrs correction explanation back to editor2-3 hrs final marketing approval//Per video, mid-range estimate:- 21-36 hours of internal team time- €1,260-€4,320 of engineering cost (loaded) - Plus: marketing manager hours, context switching, calendar drag - Plus: morale tax on engineering team- At 4 videos per month: 84-144 internal hours absorbed- At 4 videos per month: €5,040-€17,280 in hidden engineering cost
None of this appears on your video budget. It appears in engineering velocity, marketing manager burnout, and the slow death of your content cadence.
A €6,000/month retainer isn't a new line item. It's the visible replacement for €5,040–€17,280 in hidden engineering overhead you're already paying.

Answer Engine-Optimized Video
Structured transcripts, chapter markup, FAQ-formatted intros, schema-tagged captions, and AI-citation optimization for every video. Every deliverable is built to be cited by AI search engines.
Optimized for: ChatGPT · Perplexity · Google SGE · AI Overviews
Each category has its own production process, dedicated editor pairing, and technical validation requirements. We don't cross-train editors. The person who edits your Kubernetes content has shipped production Kubernetes infrastructure.
We don't produce video for consumer brands, ecommerce, or any non-technical category. The team isn't built for it. The mechanism doesn't apply. We exist for one buyer and we serve them at a depth no generalist can match.

The artifact behind the guarantee
Every video ships with a Dev Validation Receipt.
A software engineer on our team checks every CLI command, every API reference, every architecture diagram before the cut leaves the studio. The receipt names what was checked, what was flagged, what was corrected, and against which version of which documentation.
It's not a quality-control checklist. It's the artifact of the validation layer working. Your team receives it with every video, alongside the .mp4 and the source files. Forwardable, auditable, paper-trail proof for whoever signs off internally.
This is what makes the zero-syntax-error guarantee defensible.
The Calibration
Same footage. Same brand. Five executions. Point at the one that's right for your product.
The expensive problem isn't technical inaccuracy. It's the first draft arriving in the wrong style, at the wrong pace, with the wrong editorial voice. By draft 3 you've spent weeks course-correcting decisions that should have been made before production started.
Every Lumaris engagement begins with a Calibration. Five editors. Same footage. Same brand. Five distinct visual styles. You point at the one that matches your product. The retainer starts with the editorial style already locked.
Below are five executions of the same CodeScene source footage. All five follow CodeScene's brand guidelines. Each built with a different editorial philosophy, different pacing, different tempo, different level of authority.
The Calibration is not a preview. It is how Lumaris ensures the first draft matches your product's voice before any production schedule is set. You keep all five videos regardless of what you decide next. €2,500 fixed. Fully credited toward Month 1 if you continue to a retainer.

Two spots currently available
Stop solving the editor problem by hiring engineers to babysit them.
The technical-accuracy problem isn't a process problem. It's an editor-selection problem. When the editor doesn't understand your product, no review system catches everything. Generalist agencies don't have the team structure to fix this, they hire creatives, not engineers.
We work with a maximum of 10 simultaneous retainer clients. We turn down projects when capacity is full. The work that ships is the work we've fully resourced.
Two spots currently available. The Calibration is the entry. €2,500 produces three executions in your brand language before any retainer conversation.
