Castellum.AI

Assessment

Castellum.AI is used by banks, credit unions, and fintechs that screen customers and payments and spend most of their analysts’ time on false positives. It builds its own sanctions, PEP, adverse media, and high-risk ownership data instead of licensing it, runs AML and KYC screening on that data, and adds AI agents for sanctions and PEP alerts and adverse media that review hits and explain the result. Pricing is quoted. Its main competitors are ComplyAdvantage, complead, Ripjar, and Silent Eight.

Peter Piatetsky, a former US Treasury sanctions investigator, co-founded the company in 2019. Its $8.5M Series A in July 2025 came from funds backed by its own buyers: Curql, which represents more than 130 credit unions including Navy Federal, BTech Consortium, backed by more than a dozen banks, and Framework Venture Partners, backed by institutions including RBC. It follows a $4M seed round.

It fits a US bank or credit union that wants screening data and alert review from one vendor with regulator-aligned explanations. It is a weaker fit for a company that needs transaction monitoring and case management in the same platform.

User comments

These buyer-oriented points draw on Castellum.AI’s product pages and its Series A announcement.

• Upside

  “The agents cleared obvious false hits and left a written reason for our examiners.”

• Upside

  “Data and screening come from one vendor, so we stopped reconciling two list providers.”

• Downside

  “Transaction monitoring and case management still needed another vendor.”

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.
