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 frontier models from OpenAI, Anthropic and Google, alongside Perplexity's own, 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.

Zoom uses a freemium model. Free accounts get unlimited one-on-one meetings and 40-minute group meetings.

Paid plans start at $13.33/month per user for Pro (meetings up to 30 hours), $18.33/month for Business, and custom pricing for Enterprise. Zoom also charges for add-ons — Zoom Phone (cloud phone system), Zoom Rooms (conference room hardware), and Zoom Contact Center.

The free tier is the hook. The 40-minute limit on group calls creates just enough friction to push power users to pay.

And once one person in a company pays, the whole team follows because nobody wants to be the one whose meetings keep getting cut off.

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.

Eric Yuan grew up in Tai'an, a mining city in Shandong province, China. In the mid-1990s he was in his twenties and inspired by the internet boom happening in America.

He applied for a US visa. He was rejected.

He applied again. Rejected again.

Eight times in total over about two years before he was finally approved in 1997. He moved to Silicon Valley with barely any English and joined WebEx as one of its first engineers.

Yuan spent 14 years at WebEx, eventually becoming VP of Engineering. Cisco acquired WebEx in 2007 for $3.2 billion.

Yuan watched Cisco slowly bloat the product with enterprise features while the core video quality deteriorated. He kept telling Cisco leadership they needed to rebuild the product from scratch.

They kept saying no.

In 2011, Yuan quit and took 40 WebEx engineers with him. He founded Zoom Video Communications with a simple thesis: video meetings should just work.

No downloads. No lag.

No "can you hear me?" No IT department required. He built the product that Cisco refused to build.

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.

Zoom grew on one thing: it worked. In a world where every video call started with five minutes of technical issues, Zoom calls just connected.

That reliability was the entire marketing strategy for the first five years.

The freemium model did the rest. Teachers, coaches, therapists, book clubs, and small teams all started on the free tier.

When they hit the 40-minute limit, enough of them converted to paid. And every free meeting was essentially a demo — everyone in the meeting saw how good Zoom was.

Yuan obsessed over simplicity. While competitors like WebEx and GoToMeeting required downloads, plugins, and IT involvement, Zoom worked in the browser with one click.

The learning curve was essentially zero. Your grandmother could figure it out.

That turned out to be extremely important when a pandemic suddenly required your grandmother to figure it out.

Then COVID happened. In March 2020, the world shut down.

Every meeting — work, school, family, doctor, church, happy hour — moved to video. Zoom was already the easiest option.

Daily participants exploded from 10 million to 300 million in four months. The stock went from $70 to $588.

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.

Zoom

The post-pandemic hangover has been severe. Zoom's stock peaked at $588 in October 2020 and crashed to under $70 by 2022 — an 88% drop.

The company went from the most exciting tech stock on the planet to a cautionary tale about pandemic valuations. Revenue growth slowed from 300%+ to single digits as people returned to offices and competitors caught up.

Security and "Zoombombing" were early crises. In early 2020, as millions of new users flooded in, trolls discovered they could join open Zoom meetings and share offensive content.

Schools, churches, and AA meetings were disrupted. It turned out Zoom's encryption wasn't truly end-to-end as advertised.

Yuan had to halt all feature development for 90 days and focus exclusively on security fixes. It was a near-death reputational crisis.

Competition from Microsoft Teams and Google Meet intensified. Both companies bundled video calling for free into products that hundreds of millions of people already used.

Microsoft Teams integrated directly into Office 365. Google Meet was built into Gmail.

Zoom had to compete against free products from two of the richest companies on Earth.

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.

Zoom

Zoom Meetings is the core — video calls that actually work. Zoom Webinars handles large-scale events with up to 50,000 attendees.

Zoom Phone is a full cloud-based phone system replacing traditional office phones. Zoom Rooms turns physical conference rooms into one-click video meeting spaces.

Zoom Contact Center competes with established call center software. Zoom Team Chat is their Slack/Teams competitor.

Zoom Whiteboard is a collaborative digital canvas. Zoom Revenue Accelerator uses AI to analyze sales calls.

And Zoom AI Companion summarizes meetings and drafts messages.
