Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

Turn your firm's scattered contacts into one searchable relationship graph
Email, calendar, CRM and public-source data are resolved into one clean entity per person or company, ending the duplicate-record problem.
Introduction routes are scored from real shared meetings and threads, and each ranking comes with the underlying evidence attached.
Search across the whole graph and get a single answer per person instead of hunting through inboxes and CRM tabs.
Context stays attached to the person and organisation, so relationships persist when roles and staff change.
