BUSINESS MODEL

Headway

Headway makes money by taking a percentage of the insurance reimbursement for each session facilitated through the platform. When a patient sees a Headway-credentialed therapist and pays their copay, Headway processes the insurance claim and takes a service fee from the reimbursement before paying the therapist.

The model aligns incentives well. Headway only makes money when therapy sessions actually happen, which means they're incentivized to help therapists see more patients and reduce no-shows.

Therapists make more than they would on their own (because Headway's negotiated rates are often better than individual therapists can get), and patients pay only their insurance copay ($0-$50 typically) instead of full out-of-pocket rates.

Scale creates a data and negotiation advantage. With 40,000+ therapists on the platform, Headway can negotiate better reimbursement rates with insurers.

More therapists attract more patients. More patients justify better rates.

The flywheel spins.

SpaceX

SpaceX makes money three ways. First, launch services — companies and governments pay SpaceX to put their satellites into orbit.

A Falcon 9 launch costs about $67 million, which undercut the competition by 75% when it debuted. Second, Starlink — SpaceX's own satellite internet constellation, which is now generating over $6 billion in annual revenue from 4+ million subscribers.

Third, government contracts — NASA pays SpaceX to ferry astronauts to the International Space Station and the DoD pays for national security launches.

The secret sauce is reusability. Before SpaceX, every rocket was used once and thrown into the ocean.

SpaceX figured out how to land the first stage booster back on Earth and fly it again. A single Falcon 9 booster has flown over 20 times.

That's like the difference between throwing away an airplane after every flight versus keeping it for decades.

HOW THEY STARTED

Headway

Andrew Adams and Jake Sussman founded Headway in 2019 after watching people in their lives struggle to access affordable mental healthcare. The problem was specific and structural: most therapists operate as solo practitioners who don't accept insurance.

Not because they don't want to — because the process of getting credentialed with insurance companies, submitting claims, and chasing reimbursements is so bureaucratically painful that most therapists give up and go cash-only.

The result is a two-tier mental healthcare system. People with money pay $150-$300 per session out of pocket.

People without money either can't afford therapy or wait months for the few in-network providers available. Meanwhile, therapists who only accept cash are leaving money on the table — insurance pays reliably once the system works, and the patient pool is vastly larger.

Headway's solution was to build the infrastructure layer that makes insurance billing painless for therapists. They handle credentialing (getting the therapist accepted into insurance networks), claims submission, payment processing, and compliance — all the administrative work that therapists hate.

The therapist shows up, does therapy, and Headway handles everything else.

SpaceX

In 2001, Elon Musk had just sold PayPal to eBay for $1.5 billion and was sitting on roughly $180 million after taxes. Most people would buy an island.

Musk decided to buy rockets. His original idea was even weirder — he wanted to send a small greenhouse to Mars called "Mars Oasis" to reignite public interest in space exploration.

He flew to Russia three times to buy refurbished ICBMs. The Russians kept raising the price and at one point literally spat on him.

On the flight home from that last failed Russia trip, Musk opened a spreadsheet and started calculating the raw material costs of building a rocket from scratch. He realized the materials were only about 3% of the typical price of a rocket.

The rest was markup, inefficiency, and monopoly pricing by companies like Boeing and Lockheed Martin. He decided to build his own.

SpaceX was founded in June 2002 in a warehouse in El Segundo, California. Musk put in $100 million of his own money.

He hired Tom Mueller, a legendary rocket propulsion engineer who had been building rocket engines in his garage as a hobby. The first rocket, Falcon 1, was supposed to be the cheapest orbital rocket ever built.

It took six years and three spectacular explosions before it finally worked.

HOW THEY GREW

Headway

Headway grew by solving the supply-side problem first. If you can get enough therapists on the platform and credentialed with insurance, patients will come because affordable therapy is in massive demand.

They recruited therapists with a compelling pitch: "keep doing therapy, we'll handle the business side."

Insurance partnerships were the growth unlock. Headway partnered with major insurance companies (Aetna, Cigna, United Healthcare, Anthem) to become an authorized credentialing partner.

This meant Headway could get therapists in-network faster and with less friction than the traditional process.

The mental health destigmatization wave amplified demand. Post-COVID, demand for therapy skyrocketed.

The conversation around mental health became mainstream. Headway was positioned perfectly to absorb that demand by connecting patients with affordable, insurance-covered therapists.

SpaceX

SpaceX's growth strategy was simple: be cheaper than everyone, then be better than everyone, then be the only option.

They started by undercutting the launch market. The United Launch Alliance (Boeing + Lockheed Martin joint venture) was charging $300-400 million per launch.

SpaceX offered $67 million. Government agencies and commercial satellite companies started lining up.

Reusability was the real game-changer. Landing a rocket booster looked like science fiction when SpaceX first attempted it in 2013.

They failed over and over — spectacular ocean landings, explosions on drone ships, near-misses. But in December 2015, a Falcon 9 first stage landed back at Cape Canaveral.

It was the first time an orbital-class rocket had ever landed after a mission. Now they do it routinely — it's almost boring.

Starlink created a completely new revenue stream. Instead of just launching other people's satellites, SpaceX launched thousands of its own.

By 2024, Starlink had over 4 million subscribers and was generating billions in revenue. It turned SpaceX from a launch company into a telecom company.

THE HARD PART

Headway

Therapist retention is a challenge. Solo practitioners are independent by nature, and some leave the platform once they've built a full patient roster through Headway.

The platform needs to continuously demonstrate value beyond initial credentialing to keep therapists from going direct.

Insurance reimbursement rates are notoriously low. Therapists who accept insurance often earn 30-50% less per session than cash-pay rates.

While Headway negotiates better rates than individual therapists typically get, the fundamental economics of insurance-based mental healthcare remain challenging.

Regulatory complexity varies by state. Each state has different licensing requirements, insurance regulations, and telehealth rules.

Expanding to all 50 states means navigating 50 different regulatory frameworks, each with their own credentialing requirements and compliance standards.

SpaceX

The early days nearly killed the company. SpaceX's first three Falcon 1 launches all failed.

The first one in 2006 crashed 25 seconds after liftoff due to a corroded fuel line nut. The second in 2007 reached space but the second stage shut down early.

The third in 2008 failed because the first and second stages collided during separation. Musk had enough money for one more attempt.

If flight four failed, SpaceX was dead.

Flight four worked. On September 28, 2008, Falcon 1 became the first privately developed liquid-fuel rocket to reach orbit.

Musk has said he was so stressed during that period he was throwing up regularly.

The financial pressure was existential. Musk was simultaneously funding Tesla, which was also on the brink of bankruptcy in 2008.

He had to split his last $40 million between the two companies. He borrowed money for rent.

But right at the end of 2008, NASA awarded SpaceX a $1.6 billion contract to resupply the International Space Station. That contract saved the company.

Starship development has been its own saga. The rocket has exploded multiple times during testing.

Each failure costs hundreds of millions. But SpaceX treats failures as data — they move faster by blowing things up and iterating than competitors do by being cautious.

THE PRODUCTS

Headway

Headway Provider Platform — the core system where therapists manage their practice: scheduling, credentialing, claims submission, payment tracking, and patient communications. Headway Patient Matching — a directory and matching service that connects patients with in-network therapists based on insurance, location, specialty, and availability.

Insurance Credentialing Service — Headway handles the months-long process of getting therapists accepted into insurance networks, reducing what typically takes 6-12 months to weeks. Claims and Billing Engine — automated insurance claims submission and tracking that eliminates the paperwork therapists dread.

Practice Management Tools — scheduling, intake forms, session notes, and telehealth capabilities integrated into one platform.

SpaceX

Falcon 9 is the workhorse — the most-launched rocket in the world. It carries satellites to orbit and astronauts to the ISS, and the first stage lands itself for reuse.

Falcon Heavy is three Falcon 9 boosters strapped together — the most powerful operational rocket in the world until Starship came along. Dragon is the spacecraft that carries astronauts and cargo to the ISS.

It's the only American vehicle currently flying humans to space. Starlink is the satellite internet service — over 6,000 satellites in orbit delivering broadband to 100+ countries.

Starship is the big one — the tallest and most powerful rocket ever built, designed to carry 100+ people to Mars. It's still in testing but has already completed a full flight.
