Silent Eight

Assessment

Silent Eight is used by global banks whose sanctions, name, and payment screening systems produce far more alerts than analysts can clear. Its AI reviews each alert the way an analyst would, recommends whether it is a true match, and records the reasoning for auditors, and it extends the same approach to transaction monitoring and customer risk. It works on top of the screening engines a bank already runs. Pricing is quoted. Its main competitors are Quantexa, NICE Actimize, ThetaRay, and Ripjar.

Martin Markiewicz, Julia Markiewicz, and Michael Wilkowski founded the company, choosing Singapore as its base after scoring seven cities on market size, funding, and regulation. HSBC, Standard Chartered, and First Abu Dhabi Bank are among its clients, and it is deployed in more than 150 markets. HSBC became an investor in its $40M Series B in 2022, after revenue grew sixfold from October 2020.

It fits a tier-one bank drowning in screening alerts. It is a weaker fit for a fintech that needs a screening list provider and a first rules engine.

User comments

These buyer-oriented points draw on Silent Eight’s company page and its Series B announcement.

• Upside

  “The AI cleared most of our false screening hits and wrote down why for each one.”

• Upside

  “It worked on top of our existing screening engine, so we did not change list providers.”

• Downside

  “It is built for large banks, and a smaller firm would struggle to justify the project.”

Where customer reviews couldn't be found, our analysts attempted to give a voice to buyer sentiment, drawing on real information from review sites, forums and product documentation. We omit sites where vendors pay to be featured or pay for a review, plus any review the site flags as incentivized.
