This article covers Checkstep, a London-based startup that has raised £3m in a seed funding round led by Alea Capital Partners. The funding will be used to develop product features and expand commercial reach, supporting online platforms to scale AI-driven content moderation and meet tightening EU and US regulation.
Checkstep has raised £3 million in a seed funding round led by Alea Capital Partners, with participation from Slow Ventures and LookAI. The London-based company offers an AI-driven Trust and Safety platform for content moderation and compliance, and the new capital will be used to develop product features and expand its commercial reach as regulation across the EU and US tightens.
Online platforms face rising regulatory pressure — notably the EU’s Digital Services Act — and growing operational complexity as user-generated content volumes climb. Checkstep’s platform, which the company says processes more than 60 million pieces of content each month, aims to give platforms a centralised system for policy enforcement and auditability. For businesses operating at scale, reducing manual moderation and maintaining compliance are increasingly core operational needs rather than optional services.
Customers named in the announcement include Trustpilot, JustGiving, Daily Mail and MoneySavingExpert — examples that span review, fundraising and publisher platforms and illustrate the product’s applicability across different moderation use cases.
Checkstep combines machine learning models with Trust and Safety workflows to automate moderation decisions while retaining human oversight where necessary. The company reports automation of over 98% of moderation decisions and emphasises audit trails that support accountability and regulatory reporting.
The platform is positioned to handle cross-jurisdictional policy management, which matters for companies operating across the EU and US. Checkstep says the product is used to scale policy enforcement and manage risk in mission-critical workflows for enterprise customers, and it highlights recent growth and net revenue retention as indicators of commercial traction.
The round was led by Alea Capital Partners, with participation from Slow Ventures and LookAI. Alea’s investment came via its Alea Innovation One FCR vehicle, part of a broader €35 million venture strategy backed in part by the Portuguese Bank of Fomento under the Plano de Recuperação e Resiliência. Tribeca Lawyers acted as legal counsel to Alea on the transaction.
Alea describes its venture strategy as targeting enterprise software companies with product–market fit and international ambitions. In the announcement Rui Escaleira, Founding Partner, Alea Capital Partners, said:
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.

In the announcement Guillaume Bouchard, CEO and Founder, 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.
In a second statement he added:
We’re excited to partner with Alea Capital and Slow Ventures as we enter this next phase. Together, we’re building the infrastructure that makes the internet safer, more compliant, and more resilient.
Bouchard’s background includes co-founding Bloomsbury AI and experience at Meta in Trust and Safety, which the company cites as relevant to product direction and customer engagement.
The funding sits at the intersection of two trends: enterprises demanding more automated moderation tools to contain cost and risk, and investors allocating capital to B2B compliance and operations software that can scale across markets. For gaming platforms in particular — where real-time chat and community moderation are persistent problems — an AI-first moderation stack can reduce exposure to regulatory and reputational harm.
Checkstep’s raise is a reminder that startups providing infrastructure for Trust and Safety are attracting capital as regulation crystallises and platforms prioritise compliance. For the UK and European ecosystem, that translates into continued investor interest in enterprise moderation tools and broadening opportunities for companies that can demonstrate both automation and auditability.
