BUSINESS MODEL

Medallion

Medallion charges healthcare organizations a subscription based on the number of providers being managed. The platform handles initial credentialing (verifying a new provider) and ongoing monitoring (ensuring licenses stay current, no disciplinary actions arise).

The value is measured in speed and cost savings. Credentialing departments at hospitals can cost millions annually in staff salaries.

Medallion replaces much of that manual labor with software. Faster credentialing also means faster time-to-revenue — a doctor who can start seeing patients weeks earlier generates revenue weeks earlier.

The platform also manages payer enrollment — getting providers into insurance networks — which is a related but separate bureaucratic process that's equally painful and equally automatable.

Pinterest

Pinterest makes money through advertising — specifically through "Promoted Pins" that look nearly identical to organic content. This is the magic of Pinterest's business model: ads don't interrupt the experience because the experience IS discovering products and ideas.

A promoted pin for a kitchen knife set appears right alongside organic pins of kitchen designs. The user doesn't distinguish between "ad" and "content" because both serve the same purpose.

Shopping ads are the fastest-growing segment. Brands upload their product catalogs, Pinterest matches products to user searches and boards, and users can buy directly through the platform or click through to the retailer's site.

Pinterest gets paid per click or per thousand impressions.

Revenue reached $3.65 billion in 2024, up from $3.05 billion the year before, and 2024 was its first genuinely profitable year. Average revenue per user is growing but still well below Meta's — the upside is enormous if Pinterest can close that gap.

HOW THEY STARTED

Medallion

Derek Lo was working in healthcare operations when he encountered credentialing — the process of verifying that healthcare providers have the proper licenses, education, training, and malpractice history to practice medicine. Every doctor, nurse, and therapist in America must be credentialed before they can see patients at a new facility or join an insurance network.

The process was absurdly manual. It involved contacting medical schools, state licensing boards, previous employers, malpractice insurers, and the DEA — often by fax or mail.

A single credentialing verification could take 90-180 days. Healthcare organizations employed entire departments of people doing nothing but chasing down verifications through a patchwork of government databases, phone calls, and paper forms.

Lo founded Medallion in 2020 to automate this process. The platform connects directly to primary sources — state licensing boards, the National Practitioner Data Bank, DEA databases, and medical school registries — and pulls verification data automatically.

What used to take months of manual work now takes days or weeks.

Pinterest

Ben Silbermann was a former Google ad operations employee who quit in 2008 to build apps. His first attempt was an iPhone app called Tote — essentially a mobile catalog that let women browse and bookmark products from fashion retailers.

Nobody downloaded it. But Silbermann noticed something in the data: users were saving products obsessively.

The collecting behavior was more interesting than the shopping behavior.

He teamed up with Paul Sciarra, a classmate from Yale, and Evan Sharp, a designer who was studying architecture at Columbia. Together they built Pinterest — a visual bookmarking tool that let people "pin" images from around the internet to organized boards.

Think of it as a digital mood board that anyone could make.

Pinterest launched as an invite-only beta in March 2010. Growth was painfully slow at first.

Silbermann personally wrote to the first 5,000 users, giving them his phone number and asking what they wanted. The early community was overwhelmingly women interested in home decor, fashion, recipes, and DIY projects.

By 2011, Time magazine named Pinterest one of the 50 best websites. By 2012, it was the fastest site in history to reach 10 million unique monthly visitors.

HOW THEY GREW

Medallion

Medallion grew by targeting healthcare organizations that were drowning in credentialing backlogs. Telehealth companies scaling rapidly during COVID were the first ideal customers — they needed to credential hundreds of providers quickly across multiple states, and the manual process couldn't keep up.

The platform expanded to hospitals, health systems, and staffing agencies that manage large provider networks. Each customer type faces the same fundamental problem: too many providers to credential, too few staff to do it, and too many regulatory requirements to track manually.

Integration partnerships with HR systems and practice management platforms drove distribution. When Medallion plugs into a health system's existing tech stack, the switching costs climb and the data integration deepens.

Pinterest

Pinterest grew organically through women sharing boards with each other. The weddings use case was the killer app — brides-to-be would create boards for dresses, venues, flowers, and invitations, then share them with their wedding parties.

That viral loop drove millions of signups.

SEO is the secret weapon. Pinterest pages rank extremely well in Google Image Search.

Someone searching "modern living room ideas" often sees Pinterest results on page one. That drives a large stream of organic traffic from people who were not looking for Pinterest at all.

Unlike other social platforms, which compete with Google for attention, Pinterest quietly benefits from it.

The shopping pivot has been the growth unlock. Under CEO Bill Ready (former Google and PayPal executive who took over in 2022), Pinterest aggressively invested in shopping features — catalog integrations, buyable pins, merchant verification, and visual search for products.

The thesis: Pinterest users are already in a shopping mindset, so removing friction between "I like this" and "I bought this" is the straightforward path to revenue growth.

THE HARD PART

Medallion

Healthcare is notoriously slow to adopt new technology. Decision-makers at hospitals and health systems are risk-averse and procurement cycles are long.

Selling enterprise software to healthcare organizations requires patience, compliance certifications, and relationships that take years to build.

The credentialing ecosystem involves hundreds of independent data sources — each state licensing board has its own system, formats, and response times. Building and maintaining connections to all of these sources is operationally complex and requires constant updating as boards change their processes.

Competition from established credentialing verification organizations (CVOs) and legacy software providers means Medallion is displacing existing processes and vendors, not entering a greenfield market.

Pinterest

Pinterest's demographics are both an advantage and a limitation. The platform skews heavily female (over 60% women) and is strongest in home, fashion, food, and weddings.

Expanding beyond these categories to attract male users, younger demographics, and different use cases has been slow.

Competition for ad dollars is fierce. Pinterest competes with Meta, Google, TikTok, and Amazon for advertising budgets.

Most advertisers allocate the bulk of their spend to Meta and Google first, then consider others. Pinterest needs to prove its return on ad spend is competitive to win larger budget allocations.

Creator economy is underdeveloped. While Instagram, TikTok, and YouTube have massive creator ecosystems with monetization tools, Pinterest has historically been about content discovery, not content creation.

Users pin other people's content — the original creators often don't even know their work is on Pinterest. Building a creator program and driving original content creation on the platform has been a recent focus but lags far behind competitors.

WHO BACKED THEM

Medallion

Sequoia Capital led the Series B. Optum Ventures (part of UnitedHealth Group) invested — a significant strategic validation from the largest healthcare company in America.

Tiger Global and GV (Google Ventures) participated in earlier rounds.

Pinterest

Bessemer Venture Partners, FirstMark Capital, and Andreessen Horowitz were early investors. Fidelity and Valiant Capital participated in later rounds.
