DoesItHold
Practise with challenges, receive feedback, and track your progress.
AI-powered developer training platform with debugging challenges (SpotTheFault), adaptive difficulty system, real-time AI feedback and global rankings. Freemium model.
We create products and services from research in statistics and AI. Each delivery states the problem it addresses, how it was tested, and which limitations remain.
In 32 seconds, see how Lumina works: create a version, check it against stated criteria, decide, and improve.

Lumina is an AI product lab. We design, operate, and document products built from statistical and AI research. We also use them in our own work to compare what we promise with how they perform and with public sources.
Founded by a PhD and a Master's in Statistics, the company has roots in applied scientific research, statistical consulting for healthcare institutions, and corporate data science experience. This academic foundation evolved into an innovation lab focused on generative AI.
We use a "Research to Product" workflow: define a problem, build a testable product, operate it, and revise it from evidence.
Each product states which public sources and statistical assumptions guide its decisions
Small releases, explicit criteria, and review before a change becomes publicly available
We state how the product works, what we monitor, and which limitations remain

Every product in the DoesIt family follows the same process: define a question, test under controlled conditions, and record what the results support. Each product applies that process to a different problem.

The family keeps growing — more DoesIt on the way
Five bilingual courses: the eight-track Full Harness and four standalone courses. AI Coding OS is listed separately as a companion skills pack.
Understand the failure. Choose the check. Decide from evidence.
One course organized into eight tracks: CORE teaches the method and seven tracks apply it. The core path starts without code; runnable labs are available for readers who also want to implement the method.
Shared rules and checks for coding agents.
A companion pack separate from courses and tracks: 18 installable SKILL.md resources for Claude Code, Cursor and Codex.
Read tables. Understand the method. Interpret the result.
Learn the basics for following analyses in health articles, understanding why a method was chosen, and performing simple comparisons. Every topic includes an example and guided practice.
Areas of expertise we combine according to the problem, the data, and the delivery format
Our process turns a research question into a product that can be tested and used
We start with a concrete problem, check what public sources support, and define a hypothesis that can be tested.
We build a small version, define criteria, run tests, and document the limits we observed.
A version that meets the criteria receives monitoring, support, and integrations suited to its intended use.
Tell us what you need to analyse, build, or teach. We can respond with a product, consulting engagement, or training suited to the problem and your team's context.
