👋 Hi, we're Saarth and Chris, co-founders of Sixtyfour (YC X25).

The problem

In 2025-2026 alone, Texas, Nevada, Indiana, and New Jersey all sued Discord for failing to identify predators on the platform.

Anonymous accounts on Polymarket made $2.4M with a 98% win rate on Iran war bets.

Onur Aksoy ran 19 shell companies and 25 Amazon storefronts, selling $100M in counterfeit Cisco gear that ended up on US military aircraft.

Today, teams that need to follow it (Trust & Safety, KYB, threat intel, due diligence) throw analyst teams at it. Still not trusting the answer after days or weeks of research. Not to mention it doesn't scale.

Bad actors slip through. People get harmed.

What we built

The child predator's username. The scammer's banned accounts. The fraudster's shell company.

All of them leave a trail.

Impossible to connect, but the trail was always there.

Our agents have now made it possible to follow it.

Give us one identifier (a name, email, phone number, username, or company name), and we deploy agents to recursively search the open web, dark web, social platforms, court records, and regulatory filings. Every signal is cross-referenced across thousands of sources. Every data point cited.

Companies using us today:

• Cloaked uses us to uncover highly sensitive, hidden data about people, identifying attack vectors against their users.
• TRM Labs uses us to attribute bad actors to real-world identities.
• Airwallex uses us to screen counterparties for shell companies and AML risk.
• PitchBook uses us to find data on companies that are nowhere else available.
• Whatnot uses us to find qualified marketplace sellers that no platform can surface.
• Surge, Turing, and Datacurve use us to source niche domain experts for AI training data.

To name a few.

Two ways to use it

1. App at app.sixtyfour.ai
2. API + MCP server to plug into Claude, Codex, Cursor, or your own stack

The numbers

In the next couple of weeks, we’ll publicly release our benchmark results with independent validation from one of the world’s leading data labs.

Our new deep people research system sets a new state-of-the-art, outperforming Gemini 3.1 Pro, Grok 4.20, GPT 5.4, Exa Deep Reasoning, and Parallel Ultra while running 3x faster than the closest competitor.
