"Vibe Coding" = Word of the Year

What is Vibe Coding?

Vibe coding is a term coined by OpenAI co-founder Andrej Karpathy in February 2025. Collins Dictionary named it the Word of the Year for 2025.

"A new kind of coding where you fully give in to the vibes, embrace exponentials, and forget that the code even exists."
— Andrej Karpathy, OpenAI Co-founder

Instead of writing code line by line, you describe what you want in plain English. AI tools like Replit, Bolt, and Claude write the code for you. You accept suggestions, iterate on the output, and ship fast.

The result? Non-technical founders are now building sophisticated apps faster than traditional developers. Y Combinator reports that 25% of their Spring 2025 batch consisted of companies with codebases that were over 95% AI-generated.

Why This Matters for Non-Technical Founders

  • No coding bootcamp required. Start building today.
  • Validate ideas in days, not months.
  • The skill of shipping compounds. Each app teaches you something new.

The Vibe Coding Philosophy

Greg Isenberg and his guests have articulated a clear philosophy across 25+ videos. These are the core principles that separate successful vibe coders from those who never ship:

1

Ship Fast, Iterate Faster

Don't hold code too precious in the AI age. Code is now disposable; the learning comes from rapid iteration and version increments. The single biggest insight: embrace exponentials, forget the code exists.

2

Build in Public on Twitter/X

Public commitment creates urgency and drives organic visibility. Josh Pigford built in public, tweeting progress updates. This accountability hack turns shipping into content and content into traction.

3

Simple Experiences Beat Complex Ones

For consumer apps, focus on one core action and nail the onboarding experience before adding features. The most successful apps (NGL, Locket, Cal A.I.) are radically simple.

4

Distribution > Product

Building an audience before or while building products dramatically increases success rates. A great product with no distribution dies. A mediocre product with great distribution can iterate to success.

5

Use AI as Research Assistant, Not Replacement

AI excels at synthesis and analysis but requires human oversight and specific prompting. The best vibe coders understand AI's limitations and use it strategically for drafting, not decision-making.

The 7-Day Build Playbook

Based on Josh Pigford's NameSnag case study (built and sold in 8 days for $15,000) and other examples from Greg's channel, here's a practical day-by-day framework:

Day 1

Idea Validation (2-3 hours)

Use Manus AI or Perplexity to research your idea. Look for: existing competitors, target audience size, willingness to pay. If you can't find anyone complaining about the problem on Reddit or Twitter, reconsider.

Output: One-sentence problem statement + 3 potential solutions
Day 2

Build the Core Feature (4-6 hours)

Open Replit or Bolt. Describe your app in plain English: "Build me a tool that [solves X problem] for [target user]." Focus on the ONE core action. No auth, no settings, no extras.

Output: Working prototype with one feature
Day 3

Polish & Deploy (3-4 hours)

Add basic styling (Replit/Bolt handle this). Get a domain (short, catchy names outperform descriptive names). Deploy to production. Don't overthink it.

Output: Live URL you can share
Day 4

First Users (2-3 hours)

Post on Twitter/X with a screen recording. Share in relevant communities. Get 10 people to try it. Watch for: what confuses them, what they ask for, what they complain about.

Output: 10 users + feedback list
Day 5

Iterate Based on Feedback (4-5 hours)

Fix the top 3 issues. Add the most-requested feature (if it's simple). Don't add everything. Keep iterating with AI assistance.

Output: v2 with improvements
Day 6

Add Monetization (2-3 hours)

Simple paywall or subscription. Stripe integration (Replit has templates). Don't overthink pricing. Pick a number, ship it, adjust later.

Output: Payment flow working
Day 7

Decide: Scale or Sell (2 hours)

If you got paying users: consider scaling. If not: list on Acquire.com, Flippa, or Microns. Selling quickly for small money often beats holding for potential big money.

Output: Clear next step decision

Key Insight from Josh Pigford

"I could have held onto NameSnag for $100K+, but selling in 8 days for $15K let me move on to the next thing. The learning compounds faster when you ship more."

Counter-Intuitive Truths from 25 Videos

These insights from Greg Isenberg's content challenge conventional wisdom about building software:

1

Non-technical founders can build faster than developers

Conventional wisdom: You need coding skills or a technical co-founder to build software products.

Reality: Multiple examples of non-coders building and selling apps using Replit, Bolt, and AI assistants. They ship faster because they don't overthink the code.

2

Selling quickly for small money beats holding for big money

Conventional wisdom: Grow your project to maximize its value before selling.

Reality: Josh's strategy of selling NameSnag in 8 days for $15K freed him to build more. The learning from shipping 10 projects > the potential from holding 1.

3

AI content workflows actually enhance authenticity

Conventional wisdom: AI-generated content is generic and lacks personal voice.

Reality: Dan Koe's system uses AI to interview himself, extracting his actual perspective into structured content. The AI becomes a thought-organizing tool, not a replacement.

4

Short, catchy names outperform descriptive names

Conventional wisdom: Your brand name should clearly communicate what you do.

Reality: NGL, Bags, Locket, Cal A.I. Short, memorable names work better than descriptive alternatives. Clarity comes from the product, not the name.

5

Voice AI can outperform humans at phone-based negotiations

Conventional wisdom: Complex negotiations require human empathy and adaptability.

Reality: Voice AI negotiated 800+ watch deals in a single day, gathering structured data efficiently. Consistency and patience at scale beat human fatigue.

What to Build First

Based on the most discussed app categories in Greg's videos, here are high-opportunity areas for first-time vibe coders:

Micro-SaaS Tools

Small, focused tools that solve one problem. Name generators, domain checkers, email finders. Low competition, quick to build, easy to sell.

Difficulty: Easy | Time: 3-5 days

Simple Mobile Apps

Single-purpose apps with viral potential. Widget apps, social games, anonymous messaging. Focus on the core action, nail the onboarding.

Difficulty: Medium | Time: 5-7 days

AI Wrappers

Take an AI API and wrap it in a specific use case. AI for [industry], AI writing for [niche], AI analysis for [data type]. Speed matters more than originality.

Difficulty: Easy | Time: 2-4 days

Automation Workflows

Connect tools people already use. Zapier-like automations for specific industries. Sell as done-for-you service, then productize.

Difficulty: Medium | Time: 1-2 weeks

The Best First Project

Build something you personally want. The most successful vibe coders build tools they'd use themselves. You understand the problem deeply, you're motivated to finish, and you're the first user for feedback.

Common Questions (from 8,000+ Comments)

We analyzed 8,121 comments from Greg Isenberg's videos. Here are the most frequently asked questions:

How do I actually build apps without coding experience?

Start with Replit AI Agent or Bolt. Describe your app in plain English. Accept the generated code, test it, and iterate. You don't need to understand the code to ship. The skill comes from shipping repeatedly, not from studying documentation.

How do I get my app on the app stores?

For web apps, deploy directly from Replit or Vercel. For mobile apps, Replit can generate iOS/Android exports. The app store submission process has tutorials in each platform. Focus on shipping first; distribution is a separate skill to learn after.

How do I price my app?

Pick a number and ship. $5-10/month for micro-SaaS, $20-50/month for more complex tools. The data shows that apps with higher prices (upper quartile) are growing faster than the median. You can always adjust pricing later based on conversion rates.

Should I build myself or hire a developer?

In 2025, try building yourself first. The learning is worth more than the time saved by hiring. If you can't get something working after 3-4 hours, then consider getting help. But most vibe coding projects are achievable by complete beginners.

How do I sell my app if I don't want to scale it?

List on Acquire.com for larger projects ($50K+), Flippa for mid-range ($5K-50K), or Microns for smaller projects ($200-$10K). Document your traffic, revenue (if any), and tech stack. Buyers want predictable growth and clean handoff.
