ASML is the most important company you've never heard of.

The $300B+ Dutch firm makes the machines that make semiconductors. Each one costs $150m and access to them are a huge geopolitical flashpoint.

Here's a breakdown 🧵
1/ What *exactly* does ASML sell?

Its key product is an extreme ultraviolet lithography (EUV) machine, which uses advanced light technology to "print" tiny circuits onto Silicon wafers.

Only ~50 are made a year and ASML has a near monopoly on the machine technology.
2/ You def know ASML's main clients: Intel, Samsung and Taiwan Semiconductor Manufacturing Co. (TSMC).

They need EUV to keep Moore's Law ("# of transistors on microchips doubles every 2 years") alive and continue to advance computing.

Total ASML sales in 2020 = $16B+.
3/ The ASML story begins in 1984, as a joint venture between Dutch conglomerate Philips and an electronics maker called Advanced Semiconductor Materials Int.

The project had a very humble start: it was launched in a shed behind a Philip's building in Eindhoven, Netherlands.
4/ The venture's first product was called the PA 2000 stepper (think a slide projector "projecting" designs on silicon).

For years, the product failed to make headway against leading Japanese competitors (Nikon, Canon) and, in 1990, ASML was spun out as its own company.
5/ ASML scored its 1st hit product in 1991, giving it momentum to IPO in 1995.

Soon after, it acquired a # of US lithography firms and -- by the end of 1990s -- it had comparable market share to Nikon and Canon.

From there, ASML made 2 big bets that separated it from the pack.
6/ Both bets were made to keep up with Moore's law.

First: In 2006, ASML released its TWINSCAN system using immersion lithography (it utilizes water as lens to shrink the laser's wavelength = more circuits on chip).

It was ASML's first market-leading product.
7/ Also in the mid-2000s, ASML started spending huge R&D on EUV technology.

It was a massive risk, though: EUV lithography would require Samsung, Intel and TMSC to completely rebuild and redesign their fabrication plants.

From 2008-14, ASML put $5B+ into EUV research.
8/ The science behind EUV was established in the late 1980s. It was a US-led effort between the Dept. of Energy and industry (e.g. AMD, IBM, Intel).

ASML licensed EUV tech in 1999. Canon elected not to pursue it due to financial problems while Nikon chose to develop older tech.
9/ How EUV works today:

◻️ A tin droplet drops into a vacuum
◻️ It's pulsed by a high-power laser
◻️ Tin atoms are ionized, creating plasma
◻️ A mirror captures EUV radiation emitted by plasma
◻️ Mirror transfers EUV to wafer (wavelength=13.5 nanometers, basically X-ray level)
10/ The potential of EUV was so great that Intel, Samsung and TMSC -- all competitors -- jointly acquired 23% of ASML.

Intel put up the most: €2.5B for a 15% share (today, the firms have sold down most their stakes).

The first production-ready EUV machine was released in 2016.
11/ Why are EUVs so expensive?

ASML plays a role similar to Boeing for airplanes (also $100m+ products): it's an integrator of 4750 global high-value parts suppliers:

◻️ Tooling equipment (US)
◻️ Chemicals (Japan)
◻️ Lens (Germany)

(Nikon/Cannon do most production in-house)
12/ Why can ASML only produce 50 EUV machines a year?

◻️ Co-ordinating 1000s of suppliers is very difficult (just like an aircraft)
◻️ Each machine is custom (30+ variables to choose from)
◻️ Lead-time are long (speciality parts like the Zeiss lens takes 40 weeks to produce)
13/ The delivery process is nuts, too:

◻️ Each EUV weighs 180 tons
◻️ A disassembled EUV takes up 40 shipping containers
◻️ Shipping it (mostly to Asia) takes 20 trucks and 3 Boeing 747s
◻️ ASML teams must be on-the-ground to maintain them
◻️ The min spend to house EUVs is $1B
14/ Today, ASML has a 90% share in semi lithography (EUV and Deep UV).

EUV tailwinds are huge:
◻️ Semi CAPEX >$120B+ in 2021 (similar spend in following years)
◻️ Key sectors (esp. auto AKA Tesla chips) will see growth for years
◻️ Transition to 5nm process requires more EUV
15/ Even if machine sales slow, ASML's business is increasingly shifting to system maintenance, relocation and upgrades.

Over a 20yr lifespan of an ASML machine, services-based sales may reach 50% of the initial machine price (w/ high margins)...across a growing installed base.
16/ With chips needed in everything (data centres, AI, autos, mining), semis are the OIL of the 21st century.

The US has even blocked Dutch exports of EUV-licensed tech to China. As the Tech Cold War heats up, expect to hear more of ASML: the $300B+ giant that started in a shed.
17/ If you enjoyed that, I write threads breaking down tech and business 1-2x a week.

Mailchimp just sold to Intuit for $12B.

The Atlanta-based email marketing firm has taken no VC money.

Even more impressive, its CEO and co-founder Ben Chestnut has the cleanest “Experience” section in the history of Linkedin:
Built it for 21 years!!

💎🙌 should be renamed to 🌰 🙌
Great nugget from @alexrkonrad.

In 2015-16, Mailchimp valued at $2B by a NY PE firm.

Chestnut left that number on peice of paper in his safe for his wife to use (and shop Mailchimp) if anything happened to him.

This is Lex Greensill.

He founded Greensill Capital to disrupt "supply-chain finance", a $500B industry supporting global trade.

A year ago, Greensill was headed for a $30B+ IPO. Now, it's worth $0 (oh, and Softbank was a big backer).

Here's the story 🧵
1/ First, what is supply chain finance (SCF)?

Let's say you supply widgets to a car company. Typically, you give CarCo 90-120 days to pay its invoice for the widgets.

Waiting for the money sucks, though. You have working capital needs that the CarCo money could help cover.
2/ Let's say your invoice to CarCo is $1000.

A bank or finance firm will offer you this SCF deal:

1⃣ Advance you $990
2⃣ Take on the credit risk of CarCo's bill owing
3⃣ At 90-120 days, the bank/financier collects $1000 from CarCo and profits $10

When a startup claims it has “AI” or “ML” and then you take a look at the actual tech
Or as @elonmusk would say:

“I discourage the use of machine learning because it’s very difficult: 99.9% of the time, you do not need it.”

You've def heard of "The Hero's Journey", the narrative structure dating back to Homer's Odyssey in ~7th century BC.

A great way to learn the framework is comparing scene-by-scene images from 2 modern classics of the story type: "Star Wars" and "The Matrix". #TheMatrix

0/ The "Hero's Journey" was coined by Joseph Campbell, an American literary prof.

He studied ancient myths and found many shared a similar character arc (AKA the "monomyth").

It follows 12 stages, with a hero venturing from an "ordinary world" to a "special world" and back.
1/ Ordinary world

The hero's normal life before the adventure begins:

◻️ Luke Skywalker lives on a farm in Tatooine
◻️ Neo is a corporate slave in The Matrix

As you know, Elizabeth Holmes is on trial for defrauding investors and patients.

Her blood-testing startup Theranos raised $700m+ and reached a $10B valuation before imploding.

Why exactly did Theranos technology (nanotainer, Edison, miniLab) fail, though?

Here's a breakdown🧵
1/ Elizabeth Holmes dropped out of Stanford at 19 and founded Theranos in 2003.

One of Theranos' founding myths is that Holmes had a "traumatic fear" of needles and blood.

Her idea: create a system that could run all medical tests on a single drop of blood (via a finger prick).
2/ You're def familiar with the more common blood test method she tried to disrupt.

Known as venipuncture, a phlebotomist draws "whole blood" -- aka blood with none of the components (plasma, platelets) removed -- from a vein.

Then, these samples are sent to a lab for testing.
