Perplexity AI

Perplexity uses a freemium model. The free tier gives unlimited basic searches powered by a standard model.

Perplexity Pro costs $20/month and gives access to more powerful models (GPT-4, Claude, and Perplexity's own models), unlimited Pro searches, file uploads, and image generation. Perplexity Enterprise Pro is designed for businesses with team management and API access.

The company also recently introduced advertising through "sponsored follow-up questions" — a controversial move that some see as inevitable and others see as the beginning of the end for ad-free search.

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.

Aravind Srinivas grew up in Chennai, India, got a PhD in AI from UC Berkeley, and worked as a research intern at OpenAI and a researcher at DeepMind. He watched the ChatGPT explosion in late 2022 and saw something everyone else missed: AI chatbots were interesting, but AI-powered search was potentially more valuable.

Google search hadn't fundamentally changed since 1998. It still showed you a list of links and made you do the work of reading and synthesizing information.

Srinivas co-founded Perplexity AI in August 2022 with Denis Yarats (ex-Meta AI), Johnny Ho (ex-Quora), and Andy Konwinski (co-creator of Apache Spark). Their idea was an "answer engine" — you ask a question, Perplexity searches the internet in real time, reads the sources, and gives you a synthesized answer with inline citations.

No ads. No SEO spam.

Just answers.

The product launched quietly and grew through word of mouth among researchers, developers, and knowledge workers who were frustrated with Google's increasingly ad-cluttered, SEO-gamed results. Within a year, Perplexity was handling millions of queries daily.

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.

Perplexity AI

Perplexity grew almost entirely through product quality and word of mouth. The first users were AI researchers and tech workers who shared it on Twitter.

Every time someone used Perplexity and got a better answer than Google, they posted about it. The product was its own marketing.

The mobile app was a growth accelerator. By launching on iOS and Android early, Perplexity captured users who wanted quick answers on their phones.

The app was faster than opening a browser and Googling — one tap, ask your question, get an answer. Mobile usage now exceeds desktop.

Strategic distribution deals expanded reach. Perplexity partnered with SoftBank (default AI assistant on SoftBank phones in Japan), Deutsche Telekom, and various hardware manufacturers to be pre-installed as the default search assistant.

These deals put Perplexity in front of millions of users who had never heard of it.

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.

Google is the elephant in the room. Google controls 90%+ of the search market and generates $175 billion annually from search advertising.

Google has responded to Perplexity by adding AI Overviews to search results — essentially copying the answer engine concept. Google has unlimited data, unlimited compute, and the default position on every browser and phone.

Competing with Google for search is historically a death sentence.

The publisher problem is real and litigious. Perplexity synthesizes content from news articles and websites without driving traffic back to those publishers.

Multiple media companies have accused Perplexity of scraping their content and delivering it as answers, depriving them of page views and ad revenue. The New York Times, Forbes, and Condé Nast have all raised concerns.

If publishers successfully block Perplexity or win legal challenges, the product's utility decreases.

Monetization without ads is nearly impossible at scale. Perplexity initially positioned itself as the ad-free alternative to Google.

But $20/month subscriptions can't fund the compute costs of an answer engine serving hundreds of millions of queries. The introduction of sponsored questions signals that pure subscription revenue isn't enough.

Whether Perplexity can add ads without becoming what it set out to replace is the defining question.

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.

Perplexity AI

Perplexity Search is the core — ask any question and get an AI-synthesized answer with cited sources. Pro Search performs multi-step research, asking clarifying questions and digging deeper for complex queries.

Perplexity Pages lets users create shareable research articles from their queries. Collections organize saved searches and threads.

The Perplexity API lets developers integrate the answer engine into their own products. Perplexity recently added Spaces for team collaboration on research projects.

Dandy

Cloud-based case management platform where dentists submit scans, approve designs, and track orders. AI-powered restoration design that generates crown and veneer designs automatically from 3D scans, reducing turnaround from weeks to days.

Digital dental lab network with automated CNC milling and 3D printing for manufacturing restorations. Shade matching technology using AI to color-match restorations to surrounding teeth.

Integration with practice management software so cases flow seamlessly from scan to delivery.
