BUSINESS MODEL

Dandy

Vertical SaaS plus manufacturing. Dandy provides dental practices with intraoral scanners (often subsidized or free to eliminate the switching cost), cloud-based software for managing cases, and its own network of digital dental labs that manufacture the final restorations.

Dentists pay per case — each crown, bridge, veneer, or implant restoration is priced individually. The margin comes from manufacturing efficiency: digital workflows are faster, more precise, and require less manual labor than traditional hand-sculpted methods.

As volume grows, Dandy's labs get more efficient and per-unit costs drop. It's the classic razor-and-blades model — give away the scanner, make money on every restoration.

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

Dandy

Henry Stott was a repeat entrepreneur who had previously co-founded a tech company in the UK. When he looked at the dental industry, he saw a $15 billion lab market that was shockingly analog.

Here's how it worked: a dentist jams a tray of gooey putty into your mouth, waits for it to harden, mails the physical mold to a dental lab, where a technician hand-sculpts your crown out of ceramic. Turnaround: 2 to 3 weeks.

Error rate: high. Patient experience: miserable.

The technology to do this digitally had existed for years — 3D intraoral scanners, CAD/CAM software, CNC milling machines — but nobody had stitched it into a seamless end-to-end platform for the average dental practice. Stott started Dandy in 2020 to be that platform.

Provide the scanner, build the software, run the lab — and make it so easy that any dentist can switch from analog to digital without changing how they practice.

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

Dandy

Land-and-expand with dental practices. Dandy gives practices the scanner for free or at heavy discount, which eliminates the biggest barrier to switching from analog.

Once a practice starts submitting digital scans, they become recurring revenue — every patient who needs a crown is a Dandy order. Sales team targets mid-size practices (3 to 10 dentists) that are high-volume but haven't invested in digital yet.

Referral programs where existing dentists recommend Dandy to colleagues. Geographic density strategy — build lab capacity in a region, then saturate practices nearby to optimize logistics and turnaround times.

Content marketing educating dentists on why digital is better, faster, and more profitable than analog workflows.

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

Dandy

Dental practices are notoriously resistant to change — many dentists have used the same lab for 20 years and switching feels risky. The scanner hardware is expensive to subsidize at scale, creating a capital-intensive land grab.

Quality control across distributed manufacturing is hard — a crown that doesn't fit means a remake, an unhappy patient, and a dentist who might switch back to their old lab. Competition from established digital players like Align Technology and legacy lab companies investing in their own digital capabilities.

The dental industry is fragmented — 200,000+ practices in the US, mostly small businesses, which means enterprise-style sales don't work. Each practice is its own decision maker with its own habits.

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.
