London-based firm Checkstep, which develops an AI-powered Trust & Safety platform for moderating user-generated content, has secured £3 million in funding from Alea Capital Partners, with participation from Slow Ventures and Look AI Ventures, as Vestbee was informed.
- Founded in 2019 by Guillaume Bouchard, Checkstep provides software that helps online platforms manage and enforce safety and compliance rules across user-generated content such as text, images, and other posts.
- The system evaluates incoming content in real time using a combination of machine learning models and rule-based policy frameworks, categorising material as compliant, requiring human review, or needing removal depending on the level of risk or potential policy breach.
- According to the firm, it processes more than 60 million pieces of content each month and automates over 98% of moderation decisions while maintaining auditability for compliance and review purposes.
- Its customers include Trustpilot, JustGiving, Daily Mail, and MoneySavingExpert, using the platform to enforce safety policies and meet regulatory requirements across multiple regions including the EU and US.
Details of the deal
- The new funding will be used to accelerate product development, expand commercial operations, and build strategic partnerships as the company continues scaling its Trust & Safety infrastructure globally.
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,” explains Angelo Burgarello, Partner at Look AI Ventures.
