BREAKING: Norway's $2 trillion wealth fund ran a 12-month AI experiment.

They gave Claude access to their entire investment workflow.

Result: 213,000 hours saved. 20% productivity boost.

But what they found hiding in the data changed everything:

A Thread 🧵

Meet Nicolai Tangen, CEO of NBIM - the world's largest sovereign wealth fund.

700 employees managing $2 trillion in assets.

In 2022, he made a strategic decision that would reshape their entire operation.

But first, he had to address significant organizational resistance...

Tangen began systematically advocating for AI adoption across his 670-person team.

The challenge? Most investment professionals viewed AI as potentially disruptive to established workflows.

Traditional analysts were spending days on tasks that seemed impossible to automate.

Then Claude was introduced...

The first major breakthrough came with their Snowflake data warehouse integration.

Portfolio managers could suddenly query complex datasets using natural language.

What previously required technical SQL expertise now took seconds.

But this was just the initial phase...

Next, they implemented automated earnings call analysis.

Claude could process hours of executive commentary and extract key insights efficiently.

Risk managers were analyzing significantly more companies in the same timeframe.

Meanwhile, something important was happening behind the scenes...

NBIM monitors news for 9,000 companies across 16 languages.

Before Claude: Teams of analysts, days of manual work.
After Claude: Minutes of automated analysis with structured insights.

The efficiency gains were substantial, but they discovered an unexpected pattern...

The Investment Simulator revealed a critical insight:

Human portfolio managers were making predictable behavioral decisions that impacted returns.

AI could identify these patterns with 95% accuracy.

The fund was experiencing losses due to cognitive biases...

Here's where Tangen made his most decisive move:

"It can't be voluntary. If you don't use AI, you will never be promoted."

He implemented mandatory AI adoption across all 700 employees.

The organizational response was mixed...

But the measurable results were compelling:

• 20% productivity gains (213,000 hours saved annually)
• $100 million in trading cost savings
• 95% accuracy in voting decisions
• 49 million transactions optimized globally

The business case was clear.

The voting system became particularly effective.

They input 40-50 page executive compensation documents into Claude with their guidelines.

AI recommendations achieved 95% accuracy.

Even their notable "no" vote on Elon Musk's $56 billion Tesla package was AI-assisted.

Today, 100% of NBIM employees use Claude.

They're targeting $400 million in annual cost savings.

The fund that once struggled with efficiency is now leading AI adoption in asset management.

The key lesson wasn't just about technology...

It was about understanding human decision-making.

The AI didn't just automate processes - it identified costly behavioral biases.

Portfolio managers learned their emotional decisions were predictable and measurable.

AI became their analytical partner, not their replacement.

Tangen's framework for other executives:

"Don't make AI voluntary. Measure everything. Start with specific use cases."

He's now implementing selective hiring - prioritizing AI-skilled staff for new positions.

The strategy is clear: Build capabilities systematically.

P.S. If you're an SMB company in the healthcare or BFSI sector…

I've built an AI platform that helps you spot problems in your business before they happen.

Curious which insights could save you millions?

You could have "normal" blood sugar and still be aging faster than you should.

The problem isn't your fasting glucose.

It's what happens AFTER you eat.

Most people have no idea their meals are triggering invisible damage.

Here's how to see it in real time: 🧵

Your doctor checks your fasting glucose once a year.

If it's under 100 mg/dL, you're "healthy."

But that single snapshot misses everything.

It's like judging a movie by one freeze frame.

The real action happens in the 2-3 hours after you eat.

This is when glucose spikes can hit 160, 180, even 200+ mg/dL.

Then crash back down.

Your fasting number stays perfect.

But the damage is already done.

California just passed a "Billionaire Tax."

But here's what the media won't report:

The state lost MORE to fraud than this tax will ever raise.

Here's the full story (& no joke, it gets crazier the further you read): 🧵

First, what this tax actually does:

A one-time 5% tax on the worldwide net worth of any California resident with more than $1B in assets.

Payable over five years.

Sounds reasonable until you read the fine print…

It taxes unrealized gains.

Paper wealth. Startup equity. Concentrated stock positions you can't sell.

Founders like Zuckerberg built their fortunes without touching a dime for years.

Under this law? They'd owe hundreds of millions on money they never received.

Polyphenols are one of the most underrated anti-aging compounds on Earth.

Used right, they extend cellular lifespan & activate your body's youth genes.

Yet no one talks about them.

So I researched the science.

What I found will blow your mind: 🧵

First, what are Polyphenols?

Polyphenols are plant compounds found in dark berries, green tea, olive oil, and dark chocolate.

For decades, scientists overlooked them.

That was a mistake.

These compounds activate sirtuins, proteins that control how fast your cells age.

Sirtuins ON: your cells repair themselves.
Sirtuins OFF: you age faster.

This isn't speculation. It's biochemistry.

Scientists tracked 25,315 women for 25 years.

Those who followed one eating pattern had 23% lower risk of dying from anything.

Not a fad. Not restriction. A 4,000-year-old diet backed by the largest nutrition trial ever run.

Here's exactly what I'd eat (and avoid): 🧵

1/ The pattern: Mediterranean diet

But not the watered-down version you see in magazines.

The real protocol is built on one core principle:

Reduce chronic inflammation, the silent driver behind heart disease, cancer, and early death.

2/ The proof: PREDIMED trial.

7,447 high-risk adults. 4.8 years. Three groups:

• Mediterranean + extra virgin olive oil
• Mediterranean + nuts
• Standard low-fat diet (control)

Results: Mediterranean groups had ~30% fewer heart attacks, strokes, and cardiovascular deaths.

Andrew Huberman found something that gives him more peace than cold plunges, meditation, or any protocol he's ever shared.

He does it every morning. Sometimes in the middle of the night.

Most scientists won't talk about it publicly.

Here's what it is: 🧵

Prayer.

Every single night, @hubermanlab gets on his knees beside his bed.

"Like an old kid in a movie," he says.

But the science behind why this works is anything but childish.

Here's his exact routine:

First, @hubermanlab prays for other people.

Then he sits in silence. Listening.

Then he prays for his own challenges. Not for solutions. For strength to face them.

Finally, gratitude. Then sleep.

The real reason some people have unbreakable willpower…

Isn't discipline.

It's a brain structure most people have never heard of. It only grows when you suffer. And it might predict how long you live.

Here's what Stanford neuroscientists discovered: 🧵

It's called the anterior mid-cingulate cortex. The aMCC.

Stanford neuroscientist @hubermanlab calls it "one of the most important discoveries in the history of neuroscience."

And it changes everything we thought we knew about willpower.
