Checkstep, the AI content moderation platform transforming Trust and Safety infrastructure for online platforms, raised £3 million in funding. The round was led by Alea Capital Partners, with participation from Slow Ventures and Look AI Ventures.
With customers including Trustpilot, JustGiving, Daily Mail, and MoneySavingExpert, Checkstep is already safeguarding millions of users worldwide. The platform currently processes more than 60 million pieces of content each month, helping some of the world’s largest digital platforms stay ahead of increasingly complex regulatory requirements.
“Trust and Safety is a critical function for any online platform. Checkstep is building the Trust and Safety infrastructure that makes it possible to keep users safe at scale. As platforms grow and regulations are increasingly enforced, this can’t be managed through fragmented tools or manual processes - it requires a unified system to enforce policy, manage risk, and operate globally. This funding allows us to accelerate our mission to power a safer digital world.”
Checkstep’s platform automates over 98% of moderation decisions while maintaining full auditability, enabling organisations to operate with both efficiency and accountability. It has demonstrated strong growth over the past 12 months, with notable net revenue retention and increasing demand from enterprise customers.
Alea highlighted Checkstep as a strong fit within its venture strategy, backing category-defining B2B technology companies with global ambition. “Checkstep combines deep Trust and Safety domain expertise with strong, scalable technology and exceptional customer entrenchment. With rapid, capital‑efficient growth and a product embedded in mission‑critical workflows, the team has all the ingredients of a category leader as regulation turns Trust and Safety into core infrastructure for global digital platforms and defines the standard for industry.”
The new funding will support Checkstep’s continued product development, commercial expansion, and strategic partnerships as it scales its impact globally.
“Checkstep sits at the intersection of two powerful tailwinds: the explosion of user-generated content and the increasing regulatory burden on online platforms. We believe the company has built a mission-critical product in a category that is shifting from optional tooling to mandatory infrastructure. Combined with a technically exceptional team, strong customer validation, and a scalable enterprise business model, Checkstep represents the type of category-defining software company we actively seek to back.”
