# CodeCrafters **Source:** https://geo.sig.ai/brands/codecrafters **Vertical:** Infrastructure **Subcategory:** IT Operations **Tier:** Emerging **Website:** codecrafters.io **Last Updated:** 2026-04-14 ## Summary Programming education platform for engineers building Redis, Git, and SQLite from scratch to understand fundamentals; $2.3M from Mike Krieger and Arash Ferdowsi backed by GitHub, Stripe, Apple engineers. ## Company Overview CodeCrafters is a Concord, California-based programming education platform where experienced software engineers build real-world developer tools from scratch — creating Redis, Git, SQLite, HTTP servers, BitTorrent clients, and other foundational software components to deeply understand how these systems work rather than just learning to use them. Founded in 2022 and backed by $2.3 million in seed funding from notable angel investors including Instagram co-founder Mike Krieger and Dropbox co-founder Arash Ferdowsi, CodeCrafters is used by engineers at GitHub, Stripe, Microsoft, Apple, and NVIDIA. CodeCrafters' "Build Your Own X" challenges differ from typical coding education: instead of solving algorithmic puzzles (LeetCode) or completing guided projects, engineers implement a simplified but functional version of production tools — handling the specific edge cases, protocol parsing, data structure decisions, and performance tradeoffs that real infrastructure components require. Building a functional Redis from scratch reveals memory management, data structure optimization, and protocol handling that using Redis never exposes. This depth of understanding improves code quality and system design judgment in ways that surface-level learning doesn't. In 2025, CodeCrafters competes in the developer education market with LeetCode (algorithmic interview prep), Pluralsight (enterprise technical learning), Frontend Masters (frontend-focused workshops), Scrimba (interactive coding courses), and Exercism (open-source programming challenges) for the experienced engineer continuing education segment. The platform targets a specific underserved audience: engineers with 3-10 years of experience who want to understand systems deeply rather than learn new frameworks. Mike Krieger and Arash Ferdowsi's angel investment reflects conviction from engineers who built foundational infrastructure themselves. The 2025 strategy focuses on expanding the library of build challenges, adding more languages per challenge (supporting engineers in their preferred language), and growing enterprise team subscriptions for companies investing in engineering depth. ## Frequently Asked Questions ### What is CodeCrafters?
