Checkstep nets £3 million to scale AI safety platform

A London technology company is accelerating its international expansion after securing £3 million in investment to grow its AI-powered content moderation platform.

Checkstep, which helps online platforms manage user-generated content safely and efficiently, has raised the funding in a round led by Alea Capital Partners, with participation from Slow Ventures and Look AI Ventures.

The company combines artificial intelligence with Trust and Safety expertise to help businesses automate content moderation, enforce platform policies and comply with evolving regulations across global markets.

Its customers include Trustpilot, JustGiving, the Daily Mail and MoneySavingExpert.

Checkstep currently processes more than 60 million pieces of content every month, helping organisations manage increasingly complex moderation requirements while maintaining transparency and accountability.

The platform automates more than 98 per cent of moderation decisions and has experienced strong growth over the past year, driven by rising demand from enterprise customers.

Bosses say the latest investment will support continued product development, commercial expansion and the growth of strategic partnerships as the business scales internationally.

Guillaume Bouchard, chief executive and founder of Checkstep, said: “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.

“We’re excited to partner with Alea Capital, Slow Ventures, and Look AI Ventures as we enter this next phase. 

“Together, we’re building the infrastructure that makes the internet safer, more compliant, and more resilient.”

Rui Escaleira, founding partner at Alea Capital Partners, added: “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.”

Angelo Burgarello, partner at Look AI Ventures, added: “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.”
