And we're live!
Introducing The Antifraud Company (@AntifraudCo) 🧵
We raised over $5M from @AbstractVC, @BrowderCapital & @dunevc to build a private-sector DOGE, where we use AI and investigative journalism to track down those who defraud American taxpayers.
Thiel Fellow and cofounder of The Antifraud Company @alexkshieh explains how his company is using AI to identify and collect bounties on fraud:
"There are essentially two steps here. The first is that a lot of this data is unstructured. A lot of it is documents. So LLMs really speed that up — getting structured entities out of the unstructured data."
"And then we ontologize it. 'This company has this contract, has this relationship with this employee,' etc. We build this ontology knowledge-graph-like thing."
"And then we have the second layer. The rules model, essentially. My cofounders are both lawyers. They have a legal background. They've been working on the fraud issue in the legal sphere, and so they know what that looks like."
"With their input and expertise, we're able to develop this rules model, compare that to what we're seeing in the real world, and flag things that look like violations in real time."
Thiel Fellow and cofounder of The Antifraud Company @alexkshieh says he's building the Palantir of fraud detection:
"People have always been able to find fraud manually. But usually they either luck into it or they have a tip from an insider.
"We're trying to eliminate that bottleneck. We want to find the fraud using AI."
"We're tapping into all these sources of data. And once we have a good idea of what's going on, we send out human investigators to go talk to sources."
"But we want to be going outbound. We don't want to have to wait for people to come to us. Because that's just less efficient. When there's $600 billion in fraud, you're not going to get tips for most of it. And if you want to solve it, this is the way you have to go."
Congrats to our co-founder Alex Shieh!
I guess I'm a Thiel Fellow now?!
I'm building AI models at @AntifraudCo to catch fraudsters who defraud the American taxpayers. We're qui tam laws to sue the fraudsters directly, and keep 15-30% of the recovery.
Today, some fraudster's day got a bit worse... (also we're hiring!)
The Antifraud Company retweeted
Qui tam laws like the False Claims Act gives whistleblowers 15-30% of money the recover from fraudsters the US Government.
If you find billions in fraud, that’s a lot for the government and the whistleblower. @AntifraudCo is automating this with AI.
Replying to @JamesOKeefeIII
FBI will reward someone for turning in a criminal but there is no quick reward for saving millions and billions of dollars.
This needs to change.

Worried about government fraud? Go profit on it!
@alexkshieh , Founder of @AntifraudCo , breaks down for @Jason how his team will systematically uncover millions of dollars of fraud — and receive 30% under the False Claims Act.
Anyone can do find fraud, but @alexkshieh is building an automated fraud discovery engine.
PLUS
@alex and @MarcBenBrotman take a look back on @Jason interview with @bscholl back in 2016 when @boomsupersonic was just getting off the ground.
THEN @jason takes live Q/A from Founder University Tokyo! 🇯🇵

.@kevinnbass says >20% of healthcare spending (>$1T) is fraud.
@AntifraudCo is filing qui tam (pronounced "key tam") suits against big pharma, insurers, PBMs, etc, who defraud taxpayers.
If we win, we get to keep 15-30% of the recovery to offset expenses + profit. If fraud is as high as Kevin says, then @AntifraudCo is on track to become a unicorn that saves taxpayers billions.
fraudsters rn
A new fraud AAG will be the impetus for a decentralized, profit-motivated @DOGE, saving taxpayers billions.
My startup, @AntifraudCo, files qui tam suits against fraudsters in exchange for 15-30% of the recovery amount as guaranteed by the False Claims Act.
@VP & DOJ putting more resources on fraud enforcement means more attention to qui tam suits, more recoveries for taxpayers under the False Claims Act, and more incentive for groups like @AntifraudCo & others to find fraud.

🚨 @VP announces the Trump Administration will create a new Assistant Attorney General position who will have nationwide jurisdiction over the issue of fraud — focusing first primarily in Minnesota, then expanding nationwide.

Q: What does the world look like if @antifraudco wins?
A: Organized fraud takes it in the teeth till they stop.

There's a way to make a 1000x return on fraud prevention, @Chamath, but it's not through the bond market.
The False Claims Act (qui tam) says anyone who uncovers fraud can sue the fraudster on behalf of the government, and keep 15-30% of the recovery.
On a billion-dollar fraud, that's $150M+ for a private whistleblower. My startup, @AntifraudCo, does this on a repeatable basis. We have some fixed costs (salaries, tech, rent), but amortized over each case we file, we easily get a 1000x return on investment.
@AntifraudCo is essentially a decentralized, private-sector capitalist DOGE that has unparalleled margins & ROI, while also doing social good.
I think this is the most asymmetric upside bet in the market now. Position yourself smartly and you can make 10-1000x with relative ease.
How?
Even if politicians try to bury the fraud, the bond market can’t ignore it. Their math will show that even if the fraud is only 10% of total state and municipal budgets, it’s already way too much and should go to paying back debt holders.
Right now spreads don’t reflect this and are too tight - ie look at California Credit Default Swaps - it doesn’t reflect any fraud, budget shortfalls or the billionaire exodus.
There is little chance these spreads don’t move as the bond market comes back to work and processes the events of the last few days.
Now, if instead of 10% fraud, they believe that fraud is 20-30% of all tax dollars, the cost of borrowing will escalate sharply until federal, state and local governments are forced to act.
This is when the CDS trade becomes the most asymmetric profit opportunity of our lifetime.
Buy the CDS -> wait for politicians to try and bury it -> ie in California -> see the bond market increase borrowing costs -> see the CDS blow out -> asymmetric bet pays off.
The takeaway here is that the bond market lives in an alternative and adjacent universe from the politicians and media. The latter group can try to bury an issue but when the former group is asked to fund it, a reckoning happens and the former group always wins.
Our co-founder @hajsharda, a Columbia Law grad, explains how The Antifraud Company uses qui tam/the False Claims Act to prosecute fraudulent schemes by middlemen and private actors as a for-profit startup.
There is a $10B+ startup just waiting to be built in identifying and successfully litigating against federal and state fraud, double that if you can go after health and disability fraud
Like an apolitical, decentralized for-profit DOGE

.@chamath, I’m building @AntifraudCo, a startup that files qui tams against fraudsters on a repeatable basis with the help of @BarclayDavidP, a former FTC attorney & @hajsharda, an author/lawyer/antitrust whiz.
Ever since I was invited to testify before Congress at age 20 about millions of wasteful bloat at Brown I uncovered through data mining, I realized the government just didn’t have the bandwidth to stay on top of these things without the help of whistleblowers.
The TAM here is huge — 500B per year. Easily a huge market opportunity that can create multiple unicorns.
No idea this existed until today.
People can make billions ratting out the fraud: What is “qui tam”?
Via Gemini:
“Qui tam is a legal provision that allows a private individual (known as a relator) to file a lawsuit on behalf of the government to recover funds lost to fraud.
The term comes from the Latin phrase qui tam pro domino rege quam pro se ipso in hac parte sequitur, meaning "he who brings the action for the king as well as for himself."
In California, these actions are primarily governed by the California False Claims Act (CFCA), which is modeled after the federal version but tailored to protect state and local taxpayer money.
How Qui Tam Uncovers Fraud in California:
The CFCA is designed to incentivize "insiders"—employees, contractors, or competitors—to expose schemes that the government might not otherwise detect.
1. Common Types of Fraud Reported
• Healthcare/Medi-Cal Fraud: Overbilling, "upcoding" services, or billing for treatments never provided.
• Contractor Fraud: Using substandard materials on public construction projects or inflating labor hours.
• Grant & Education Fraud: Misusing state funds provided to schools, universities, or research institutions.
• Procurement Fraud: Conspiring to rig bids for state contracts or providing defective products to state agencies.
• "Reverse" False Claims: Intentionally underpaying money owed to the state (e.g., hiding a debt or under-reporting natural resources extracted from state land).
2. The Process: Filing "Under Seal"
To uncover fraud without alerting the bad actor, the process follows a specific "cloak and dagger" procedure:
• Confidential Filing: The whistleblower files the lawsuit in secret (under seal). Not even the defendant knows they are being sued yet.
• Government Investigation: The California Attorney General (or local prosecutor) has 60 days (often extended) to investigate the claims privately.
• Intervention Decision: The government decides to either intervene (take over the case) or decline (let the whistleblower pursue it on their own).
Whistleblower Rewards and Protections
California offers some of the strongest incentives and protections in the nation to encourage people to come forward.
Did somebody say apolitical decentralized for-profit DOGE 👀?!

New podcast is out with @ddayen & @matthewstoller hosting @antifraudco's, @BarclayDavidP & @hajsharda who enlighten us on their plan to profit by prosecuting the fraudsters stealing your tax dollars.
The best part is you can help!

NEW AT 11 😆: @alexkshieh has dropped out of @BrownUniversity after DOGEing thousands of administrators to find out why tuition is so high.
Now he's building the Antifraud Company.
No more B2B SaaS — We are introducing "snitching as a service."
Unlike software subscriptions that deliver questionable value, our value prop is clear — we find fraud first, and only then do we get paid a percentage of what we deliver.
The Antifraud Company raises $5.1M from @AbstractVC, @BrowderCapital & @dunevc (cue the @TBPN gong noises)
