Editorial Verdict
Best for
Trust & safety analysts investigating fraud rings and banned accountsInvestigative journalists needing deep background on individualsBackground check professionals requiring sourced evidenceCorporate security teams vetting partners or hiresRisk and compliance officers screening for sanctions and PEPs
Not ideal for
Casual social media lookup without budget for enterprise pricingUsers needing a mobile app for on-the-go checksReal-time monitoring without API integrationSmall teams or freelancers who need transparent self-serve pricingUsers who only need basic search engine results without structured dossiers
If you need deep, automated people intelligence with sourced evidence at scale, Sixtyfour is a top pick among specialized tools. But the lack of transparent self-serve pricing limits access for smaller teams or individual researchers. It's a strong bet for enterprise trust & safety and investigative teams that can justify the cost.

About Sixtyfour
Contact SalesIntermediateAPI availableWeb · API
Sixtyfour is an AI-powered intelligence platform that researches people and companies from any starting identifier — name, email, phone, social handle, or company. It deploys autonomous agents that browse public and dark web sources, official records, and unstructured documents to build comprehensive dossiers with cited evidence. The platform is designed for trust & safety teams, investigators, analysts, and any professional who needs rapid due diligence on individuals or entities. Users simply provide an identifier, and the system returns a structured profile with social media accounts, entity affiliations, risk signals (sanctions, PEP status, court records, adverse media), corporate irregularities, and dark web exposure — all with source links. Sixtyfour differentiates itself by combining multiple AI agents that work in parallel to cross-reference data from over 20 sources. They claim to rank #1 on people research benchmarks against Exa, Parallel, and Grok. It offers both a self-serve web interface and an API for programmatic access, with SOC 2 compliance. Recent blog posts highlight agent-driven reverse username search, identity resolution for banned scammers, and detection of rented gig-worker accounts. Compared to alternatives like Exa or Parallel, Sixtyfour focuses exclusively on deep, automated people intelligence rather than general web search or background check databases, delivering richer profiles with cited evidence for investigative workflows.
Behind the Verdict
Sixtyfour aims squarely at professionals who need more than a surface-level search — think trust & safety analysts investigating fraud rings, compliance officers screening for sanctions, or journalists digging into a subject's background. The AI agents don't just return links; they cross-reference across multiple sources and flag risk signals like dark web exposure or corporate irregularities. That depth sets it apart from general-purpose search tools or basic background check services. We like the source-backed output — every data point has a citation, which is critical for investigative and legal workflows. The benchmark claim (#1 on people research) is aggressive but worth testing against your own use cases. Where it bites: there's no public pricing. You'll need to book a demo, which suggests enterprise-level costs. That also means no self-serve trial to kick the tires. For a small team or a freelance investigator, the opaque pricing could be a dealbreaker. If you need a quick, casual people lookup, stick with free tools. But if you're building a due diligence pipeline or need automated identity resolution at scale, Sixtyfour appears purpose-built for the job. The recent blog posts on reverse username search and detecting rented gig-worker accounts show they're iterating on real investigator pain points.
