Codility
Codility runs online coding tests and technical interviews for hiring engineers.
Codility has real enterprise customers and a compliance angle worth watching, but shrinking headcount and no fresh capital put it on the back foot against a faster-shipping HackerRank.
Codility sells software that tests whether job candidates can write code, used by large companies to screen engineers. It is increasingly easy to copy because HackerRank, its main competitor, has more money, more customers, and is shipping AI features faster. The one thing that could save Codility is a new EU regulation (starting August 2026) that requires hiring tests to prove they do not discriminate, and Codility has built tools to do that, but only if it can convince customers to buy and Codility has enough cash to keep building.
Codility headcount or web traffic stabilizes or grows in H2 2026 reports. Would show the shrinkage trend is reversing rather than continuing.
Codility raises new capital or discloses profitability. Would show it can fund AI feature parity with HackerRank despite 78+ month funding drought.
- Headcount down ~50% from peak
- No new funding since $22M round, Jan 2020
- Web traffic down 9.3% quarter over quarter
- No new funding raised since January 2020, limiting capital for AI feature parity.
- Headcount down roughly 45% from 2021 peak with hiring nearly frozen (2 open roles mid-2026).
- Core coding-assessment premise erodes as AI generates more code, per rival HackerRank's 2025 data claim.
- HackerRank out-shipping Codility on AI interviewer and proctoring features through 2025.
- Greenhouse ATS integration deprecation could cause enterprise customer churn during migration.

- Is Codility profitable in 2026?
- Codility has not disclosed profitability. It raised a $22M Series A in January 2020 and has reported no new funding round since, per a mid-2026 tracker noting funds were raised '78 months ago.' Independent revenue figures are stale and conflicting, so its current financial health cannot be confirmed.
- Is Codility shrinking or laying off staff?
- Yes. Headcount fell from about 201 employees in September 2021 to roughly 109-118 by mid-2026, and Codility's own site now describes itself as 'a focused team of fewer than 100 people' as of May 2026. Only 2 open roles were tracked globally as of June 2026.
- Who is Codility's biggest competitor?
- HackerRank is Codility's closest and most active rival. HackerRank claims 2,500+ customers and 26M+ developers (vendor-claimed, Nov 2025) and shipped an AI Interviewer, Proctor Mode, and model-eval suite ASTRA in 2025, while Codility launched a smaller OpenAI-based AI Copilot in November 2025.
- Could AI replace Codility's coding assessment platform?
- Partially. HackerRank's 2025 Developer Skills Report claims roughly one-third of code is now AI-generated (vendor-claimed), eroding the premise of pure coding-skill testing. Codility is countering by assessing 'AI-Assisted Engineering' skills since October 2024, but its core screening task remains automatable.
- Who owns Codility?
- Codility is privately held, not publicly traded. CEO is Natalia Panowicz. Investors include Oxx, Kennet Partners, Seedcamp, SaaS Capital, HardGamma Ventures, and YLD, with the most recent disclosed round being a $22M Series A led by Oxx and Kennet Partners in January 2020.
- Does the EU AI Act affect Codility?
- Yes. The EU AI Act's high-risk obligations for recruitment and candidate-evaluation AI systems take effect August 2, 2026, with fines up to 15 million euros or 3 percent of global turnover for non-compliance, directly impacting how Codility's assessment tools must document risk and oversight.
