CodeSignal is a technology firm that provides a platform designed for skills evaluation and development, catering to both organizations and individual users. Established in 2015 and based in San Francisco, California, the company originally operated under the name CodeFights before rebranding to CodeSignal in 2018.
History
The company was founded in 2015 by Tigran Sloyan, Aram Shatakhtsyan, and Felix Desroches. Initially known as CodeFights, it offered a competitive programming platform centered around timed, head-to-head coding challenges.
In 2017, CodeFights introduced an interview practice feature aimed at assisting users in preparing for technical interviews through specialized questions and assessments. The transition to the CodeSignal brand in 2018 signified a strategic pivot toward technical recruiting solutions and brought forward the Coding Score—a standardized measure enabling developers to showcase their programming abilities to potential employers.
October 2020 saw CodeSignal secure $25 million in a Series B funding round led by Menlo Ventures, with Capital One Ventures and CM Ventures also participating. This investment supported the expansion of its assessment platform and operational growth.
In September 2021, the company completed a $50 million Series C financing round led by Index Ventures, with contributions from Menlo Ventures and Headline. These resources have been allocated toward advancing technical assessment products and research efforts.
Products and Services
CodeSignal delivers tools for assessment and learning that help measure and improve programming skills.
The platform includes task-oriented simulations, standardized coding evaluations, and an authentic coding environment extensively utilized by employers during recruitment.
In 2024, CodeSignal introduced CodeSignal Learn, which incorporates an AI-powered educational assistant named "Cosmo," developed using large language models such as ChatGPT.
Also in October 2024, CodeSignal released the AI Benchmarking Report, which analyzed AI models’ coding proficiency against that of human engineers. Although AI demonstrated notable strengths, the highest-performing human candidates achieved superior average scores and problem-solving rates.
Additionally, the company publishes an annual University Ranking Report that evaluates academic institutions based on student results from CodeSignal’s General Coding Assessment.
