Introducing our RECON benchmark in partnership with @hud_evals

RECON is the first benchmark dedicated to the people research needed for due diligence, fraud investigations, and data enrichment

Sixtyfour's XHigh ranked first among the systems evaluated, with +70.6% weighted accuracy

Here’s how the evaluation worked 🧵

SixtyFour’s people research agents are critical to protecting companies like Beehiiv and Mercor from fraud.

Here are the key results from RECON validated by @hud_evals

+46.7 percentage points over Exa agent xhigh

+29.5 percentage points over Parallel Ultra 2x

+45.5 percentage points over GPT-6 Astra (max)

+44.3 percentage points over Claude Opus 5.5 (xhigh)

We ran Sixtyfour on Exa’s people and company search benchmarks.

82.8% of our people search results matched the criteria. Exa’s published score: 63.3%.

That is roughly 20 more relevant people for every 100 results.

We came out ahead on all six measures in the chart.

Please don't do this

[Saarth Shah @saarth_]

Every person who signs up in the next 48 hours on Sixtyfour gets their full digital footprint pulled anonymously.

Our agents go out and find it live, the way a human investigator would. Nobody is doing this with agents yet.

We're working closely with Security and Trust and Safety teams on this very problem.

We can unmask the person behind a bad actor. Find DPRK workers. Map who people are connected to. Surface fake or synthetic accounts. Verify someone is who they say they are.

The best way to understand what we can do for you is to watch us do it to you.

See you at (app dot sixtyfour dot ai)

@zarazhangrui X really does feel like a natural extension of your social circle, so it makes a lot of sense behaviors like attributing others and learning/building together resonate. I guess its just that simple
