"Your only strategy is speed. You must innovate faster than anyone else. It's like running a marathon in full sprint."
In 2025, building AI applications is easier than ever. But surviving as a startup? That's become much harder.
Not because the technology is too complex. But because OpenAI, Google, and other giants are crushing every rising innovator with capital and traffic.
When ChatGPT can generate code in one click and Gemini can write business plans automatically, what do startups have left?
Recently, at a Y Combinator founder session, Perplexity CEO Aravind Srinivas gave a rare, brutally honest talk. Sharing how his startup has managed to grow in the shadow of giants like Google and OpenAI.
This high-density, 40-minute conversation wasn't another feel-good startup story.
It was a real survival guide for building in the AI era:
- Speed is everything: When giants copy your idea, you must ship faster than their internal approvals.
- Precise positioning: Own a niche the giants can't fully commit to.
- Embrace imperfection: Turn every bug into a co-creation moment with your users.
This article breaks down how Perplexity broke through the AI siege in three years. Boiling it down to 3 startup laws of the AI age: Focused breakout × Extreme speed × Co-building with users.
Find the battlefield where giants can't commit
"Google has the best engineers in the world, but they can't build good AI search," Aravind said bluntly.
As the crowd gasped at this "provocation," he followed up with a sharp insight: The greatest strength of tech giants is also their biggest weakness.
The 2023 Google Bard demo fail—which wiped 6% off their stock—became a classic case of this tension.
Aravind's analogy was sharp: "It's like asking an Olympic gymnast to compete in weightlifting."
Google's ad engine generates $200B a year, but that means:
- They can't risk adding AI answers to core search—it breaks the ad model
- They can't afford any public mistakes—too risky for stock price
- They won't rebuild their entire business model for AI—too high opportunity cost
This "dancing in chains" dilemma became Perplexity's entry point: "We focus on what Google won't do—giving precise, ad-free answers with clear sources."
A compelling moment came during the live demo:
- When users searched "hotels near Golden Gate Bridge," Google showed paid booking site ads.
- Perplexity returned a clean hotel list with Tripadvisor ratings and booking links.
"That's how search is supposed to work," said one serial founder in the audience. "Google knows the right answer—but their business model won't let them show it."
When AI can write code—what's the real moat?
"Today, fixing a bug is faster than building a new feature used to be."
Perplexity's development process shocked traditional engineers:
- PM snaps a photo of a UI bug on their phone → sends to Cursor AI
- AI suggests code edits in SwiftUI
- Engineer reviews → pushes hot update instantly
Example: In March, a user reported that long conversations weren't saving.
A typical company would:
- Spend a day reproducing the issue
- 3 days debating a fix
- 1 week coding and testing
Perplexity's timeline:
- 10:00 AM — user email lands in CEO's inbox
- 10:15 — AI suggests 3 solutions
- 11:30 — one is selected, coded, and tested
- 2:00 PM — pushed to 20% of users
- By 5:00 PM — full release based on feedback
"This isn't a tech miracle—it's a mental model shift," Aravind explained. "We don't aim to 'get it right the first time,' we aim to 'fail fast and fix faster.'"
The compounding effect is huge:
- 3× higher user retention (bugs fixed in hours)
- 5× higher engineer productivity (AI handles 70% of repetitive tasks)
- Faster iteration than Google's AI search updates
"Google IO announces updates once a year. We ship major updates every two weeks," Aravind said. The crowd laughed knowingly.
The browser: A forced D-Day landing
"If we only do search, ChatGPT will eventually eat us alive."
So when Aravind announced Perplexity was going all-in on building a browser, even YC partners were surprised.
But the logic was ruthless:
"The browser is our Normandy landing," said Aravind. "If all the beaches are blocked, you have to create your own."
Cognitive OS vs Chat Box
Perplexity's browser unlocks next-level use cases:
Use Case 1: Smart price tracker
"Find the cheapest SFO--London flight in the last 6 months, skip red-eyes" → scans 10+ sites and compiles report
Use Case 2: Research assistant
"Summarize all funding rounds in AI pharma over the last 3 years" → pulls from Crunchbase, academic papers, earnings calls
Use Case 3: Personal life assistant
"Look at my calendar and email—suggest 3 best times to work out next week" → auto-books a gym slot
"It's not a tool. It's an extension of your cortex."
In the demo, the browser ran 12 async tasks at once: monitoring competitors, renewing cloud services, tracking packages — All driven by natural language.
The CEO as Chief Bug Officer
"This morning, I fixed 3 bugs myself. Probably the worst time management for a CEO."
The audience laughed—but related.
In the AI era, leadership is changing:
Traditional CEO:
- Strategic planning
- Fundraising
- Team building
AI-era CEO:
- Code sense: Smells bugs early
- Feedback radar: Sees signal in user complaints
- Bug miner: Turns every flaw into product gold
The "Kitchen Model"
Aravind runs Perplexity like a restaurant kitchen:
All engineers take turns on customer support. "When you see a user miss a flight because of a bad search result, it hits harder than any KPI."
This immersion culture brings powerful results:
- Response time: 6 hours → 23 minutes
- "Bug marathons": 100+ edge cases fixed per week
- 60% of product improvements come from user emails
"Google could never do this," whispered a former Googler in the crowd. "Their CEO will never see a real user's pain."
The real advantage of being small
"AI hasn't changed the nature of business — It just cut the cost of innovation from millions to the price of a lunch."
He ended with one slide that hit like a punch:
"That's the startup advantage," Aravind said. "They fight with aircraft carriers. You attack with speedboats."
As people left, they were handed a card listing all of Perplexity's public bugs. "Come challenge our weaknesses." A humble and bold invitation — Maybe the most badass startup statement in the AI era.
