The gap between commercial LLMs and open-source alternatives is closing fast. OpenAI charges ~$2 per million tokens; Llama gets you there for fractions of a cent. The endgame looks like internet pricing — you'll pay for a utility, not per megabyte.

The build-vs-buy debate, Akshaya notes, is not new — he watched the same argument play out with SAP and Oracle ERP systems two decades ago, and enterprises eventually concluded that keeping up with the resulting tech debt was untenable. The same calculus is now playing out with AI, but under enormous time pressure as CFOs chase ROI proof for their investors. Akshaya structures the decision around four factors. Time to market and speed to impact: can you afford the months or years it takes to build from scratch when an off-the-shelf system can be online in one to two weeks? Total cost of ownership: the CapEx of a custom build almost always makes integration look attractive in the near term. Talent scarcity: the pool of AI engineers who can build systems at scale is tiny, and Stanford or Berkeley graduates in this space command $500K or more per year. [1] — Akshaya Murthy "AI experts: ~500K/year minimum salary: Hiring a single AI expert capable of building systems at scale costs at least $500K per year and is …" 17:11 Security and compliance: not every company has the expertise to build enterprise-grade security into a new product, and every AI vendor now ships with enterprise-grade privacy and GDPR compliance as table stakes. For most enterprises, integration wins on all four counts — and it frees up scarce development bandwidth to focus on building only what truly needs to be custom.
Hiring a single AI expert capable of building systems at scale costs at least $500K per year and is rising as the talent wars heat up.
AI has become the number one investment line item in company priorities, overtaking cybersecurity.
AI model updates are happening on a weekly basis from commercial providers and on a daily basis on platforms like Hugging Face for open-source models.
Sam had no coding knowledge, so he used ChatGPT voice mode to generate his entire codebase and copy-pasted it into Notepad. A friend later introduced him to Cursor, and he never looked back.
Copy days of Discord chat history, paste it into ChatGPT, and ask it to list recurring pain points. The ones that come up most often are your best product bets.
Sam's top advice: when prompting Cursor, tell it to architect code for 100,000 users from day one. The AI changes its approach, building scalable frameworks instead of brittle one-user code.
With AI coding tools like Cursor, Bhanu replicates an existing free tool for a new keyword in under 5 minutes. What used to be a multi-day build is now a lunch-break task.
Ahrefs, SiteGPT, Cal.com, PostHog, Datafast, Sibyl AI, Bento, Feather, Featurepace, Mintlify, Cloud Code, ChartMogul — Bhanu runs his entire business solo with these 12 tools.
PropGPT runs on React Native with TypeScript and Python for ML, Neon for the database, RevenueCat and Superwall for monetization. LLM costs are $20/month, data APIs $100/month, and after $10K in monthly marketing spend, margins sit at roughly 50%.
Game apps keep users engaged long enough for ads to pay off. Tool apps don't — so if you're building a utility, ads are almost always the wrong call and subscriptions are your only real lever.
Inside SEO Bot, a single button labelled 'Boost My Domain Rating' routes users directly to Listing Bot. That one interaction converts a user of one tool into a user of two — without any marketing cost.
Directory listings are a powerful but underrated growth channel — but only if your product is genuinely interesting enough to earn the click. AI products have a natural advantage here because they're easy to package in a compelling, clickable way.
