SQLMaxx helps career switchers learn SQL well enough to land an entry-level data analyst job, even if they have never opened a database before.

SQL is the one skill almost every analyst interview screens for, yet most people learn it the hard way: jumping between tutorials, courses, and question banks, finishing a few, and forgetting half within a week. Tutorials end. Question banks assume you already know SQL on the first problem. Nothing tells you whether you are actually ready.

SQLMaxx replaces all of that with one engine. You move through 66 concepts in dependency order, from SELECT to complex CTEs, so you are never asked to write SQL you have not been taught. After every answer, the engine updates a real measure of how well you know each concept, then brings each one back for a short review right before you would forget it. That spaced review is what makes SQL stick instead of fading once the course ends.

Get a query wrong and Maxx, the built-in AI grader, explains in three sentences what your query did, the rule behind the result, and the pattern the problem wanted. It is included on every plan.

What makes it different:

-It adapts up and down to your level. Most courses and question banks are the same for everyone. -It tells you when you are ready. When all 66 concepts read green, the SQL part of an analyst interview is handled. Most tools never tell you where you stand. -You practice on real business data in a real Postgres database in your browser, not toy examples.

Questions & Answers

As answered by people managing Sli.do and SQLMaxx.

What makes your product unique?

SQLMaxx's answer:

SQLMaxx is built around an engine that measures what you actually know, not just what you have clicked through. As you practice, it tracks a real probability that you have learned each of the 66 SQL concepts, brings each one back for review right before you would forget it, and explains every wrong query in plain language. Most tools hand you lessons and problems and leave you to guess whether you are ready. SQLMaxx tells you.

Why should a person choose your product over its competitors?

SQLMaxx's answer:

Most SQL courses and question banks are the same for everyone. They end when the videos end, assume you already know SQL on the very first problem, and never tell you whether you have actually retained anything. SQLMaxx adapts to you, both up and down, so it meets a true beginner and still stretches a stronger learner. It brings concepts back before you forget them, explains exactly what went wrong on each query, and gives a clear readiness signal: when all 66 concepts read green, you are ready for an entry-level analyst interview.

How would you describe the primary audience of your product?

SQLMaxx's answer:

Career switchers and beginners who want to break into data analytics, including people who have never opened a database before. SQL is the main skill that entry-level analyst interviews screen for, and SQLMaxx is built to take someone from zero to interview-ready. It is made for self-taught learners who keep bouncing between tutorials and never feel ready, rather than for teams or enterprises.

What's the story behind your product?

SQLMaxx's answer:

SQLMaxx started from a common frustration: people trying to break into analytics jump between tutorials, courses, and question banks, finish a few, forget half, and still have no idea whether they are ready. The best learning systems in other fields, like the adaptive math programs that measure mastery and schedule review at the right moment, solve this by tracking what a learner truly knows. No one had built that for SQL. SQLMaxx is that system: a single adaptive engine that maps the 66 concepts an analyst needs, measures your grasp of each one, and tells you the moment you have it. It is independently built, focused on doing one thing well.

Which are the primary technologies used for building your product?

SQLMaxx's answer:

  • React and Astro for the web app and the public lesson pages
  • PGlite, which runs a real Postgres database right inside your browser, so you can write and run SQL with nothing to install
  • CodeMirror for the in-browser SQL editor
  • Custom learning algorithms for mastery tracking and spaced review
