Service · Product demo
Real calls, real output, code that runs. The demo does the convincing.
// what we do
Lumaris produces product and API demo videos for developer audiences.
Editors who write code build demos around real working calls, checked line by line, so the demo developers judge your product by runs correctly the first time and holds attention to the end. From €2,000 per video.
// who this is for
A product demo is the highest-intent video you will make. Someone is deciding whether your tool does the job. A demo that is slow, vague, or subtly wrong does not just fail to convince, it actively talks them out of it.
We build demos that respect a technical evaluator's time: fast to the value, honest about the workflow, and precise on every command and API call on screen.
// the case
Developers will forgive a slow website. They will not forgive a syntax error in your demo. And a screen recording with a voiceover hits a ceiling: they watch for the information, then leave without subscribing, returning, or sharing.
It shows the real thing doing the real job, fast. The strongest demos open on the outcome, then earn the detail, rather than starting with a five-minute tour of the dashboard. They use the actual product, not a mock, and they do not hide the step where a competitor's demo would cut away.
For API and developer products that means real requests and responses, real terminal output, and code that runs, because the audience will try to copy it.
Two reasons. The pacing assumes a patient viewer who does not exist, so attention is gone before the value lands. And the content is either too shallow to be useful or subtly inaccurate, which a technical buyer reads as a tool they cannot trust.
We engineer the open, re-hook before attention drops, and validate every command so the demo is both watchable and correct. Built for how developers watch is not a slogan here, it is the measurable difference between a demo that converts and one that gets closed.
About five days to a first draft, because the speed is a documented system rather than a scramble. One demo is €2,000, a complete purchase you keep, with no retainer required; the retainer, from €6,000 a month, is the upgrade for the whole video arm. The honest frame is build versus buy against a €60,000 to €120,000 in-house hire, not a comparison to another vendor.
The simplest start is a free spec edit on a demo you have already published, so you can compare the before and after on your own product.
// dev-validation
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.
// build vs buy
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.

Real requests and responses, real terminal output, and code that runs, because the audience will try to copy it. The strongest demos open on the outcome, then earn the detail, instead of a five-minute dashboard tour. Every call is checked line by line, so the thing they judge the product by works.
A raw screen recording with a voiceover hits a ceiling: developers watch for the information, then leave without subscribing, returning, or sharing. A produced demo engineers the open, re-hooks before attention drops, and keeps every command accurate, which is the difference between a demo that converts and one that gets closed.
Yes. A first draft lands in about five days, and the demo built around real working calls is the asset a launch turns on. It runs correctly the first time, holds attention to the end, and feeds the short clips that surface it, so the highest-intent video you make actually does the convincing.
