Starter Story
An indie dev grew his AI SaaS to $13K/month with zero paid marketing by building 50 free tools that rank on Google — and each new tool now takes under 5 minutes to create with AI.
TL;DR
Bhanu, an indie developer from India, grew SiteGPT to $13K/month in MRR without spending a dollar on paid marketing — using a strategy called "engineering as marketing." He built nearly 50 free tools that rank on Google for low-competition keywords, driving 50,000 monthly visitors and around 300 leads per month [1] — Bhanu "90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competi…" 10:35 . His 7-step playbook using Ahrefs keyword research is shared in detail [2] — Bhanu "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 …" 12:00 . The single most useful takeaway: builders who hate marketing can let their code do the selling.
Bhanu, an indie developer who grew SiteGPT to $13,000 MRR with zero paid marketing, shares his engineering-as-marketing playbook for driving free organic traffic through strategically built free tools.
The episode opens with a pair of back-to-back pre-roll sponsor reads before any guest content begins. The first is a humorous skit for Indeed's Sponsored Jobs product, featuring a hairdresser disaster caused by using hedge shears, with the punchline that qualified professionals on Indeed would have prevented the catastrophe. The second is a straightforward promotional read for Flaschenpost, a German grocery delivery service, offering new customers €10 off each of their first three orders using promo code HALLO30. Both reads conclude with clear URLs and calls to action. These two spots take up the first full minute of the episode.
Pat Walls opens the main content with a sharp hook — almost 1 million website visitors, $0 in paid marketing. He introduces Bhanu as a builder, not a marketer, and frames the episode explicitly for the segment of his audience that always asks: 'building is cool, but how do I market my app?' Pat promises to deliver Bhanu's 7-step process that drives thousands of monthly clicks for free, and flags it as essential viewing for builders who hate marketing. The framing is deliberate: this is not a story about a marketer who can code, but a coder who found a way to market without becoming a marketer.
Bhanu takes over the mic and delivers a remarkably compact origin statement: two SaaS products built, one sold for $250,000, one growing to $13,000 MRR with approximately $500,000 in cumulative revenue since March 2023 [1] — Bhanu "$500K total revenue since launch: SiteGPT has generated approximately $500,000 in total revenue since its launch in March 2023." 03:48 . He notes immediately that most of his customers come through a strategy he calls 'engineering as marketing,' signalling that the conversation is going to be both tactical and replicable. Pat probes further, asking Bhanu to explain what SiteGPT actually does — it's an AI chatbot builder that gives any website a 24/7 intelligent assistant, sold on a subscription model. The business is real, the numbers are disclosed openly, and the stage is set for a deep dive.
With unusual transparency, Bhanu pulls back the curtain on SiteGPT's entire business model. The traffic — 50,000 monthly visitors — breaks down into approximately 200 leads, 60 trial sign-ups, and somewhere between 15 and 24 new paying customers each month [1] — Bhanu "50,000 monthly visitors become 200 leads, 60 trials, and roughly 15–24 new customers per month at ~$100 average revenue each. Add a $1,700–…" 06:00 . At an average revenue of around $100 per customer, those 130 active businesses total $13,000 in MRR. But the metric Bhanu is most proud of is the customer lifetime value: $1,700 to $1,800 per customer [2] — Bhanu "SiteGPT LTV ~$1,700–$1,800: The average customer lifetime value for SiteGPT is approximately $1,700 to $1,800, which Bhanu considers unusua…" 06:55 . Pat describes the LTV as 'really impressive,' and it's easy to see why — at that retention level, every new customer is worth nearly two years of subscription revenue. The conversation then sets up the obvious next question: how does he get all that traffic for free?
Before getting into the marketing tactics, Pat asks Bhanu to rewind and share his origin story. The arc is a classic indie hacker trajectory: graduated, joined a large startup, felt out of place within 8 months [1] — Bhanu "SiteGPT reached $10K MRR in month 1: SiteGPT hit $10,000 MRR within its very first month of launch, driven largely by early traction in the…" 09:42 , quit, moved back to his parents' house to eliminate living costs, and started building. His first app, Feather, grew to around $5,000–$6,000 MRR. Then in early 2023, he noticed the explosion of AI tools on his Twitter feed and decided to spend a weekend building something with the technology — not to launch a product necessarily, but simply to learn. That experiment became SiteGPT. Within two weeks of having the idea, he launched; within one month, it hit $10,000 MRR[2]. The growth was so fast that he had no bandwidth left for Feather, so he sold it for $250,000 and went all-in on SiteGPT. It's a story about momentum, opportunity recognition, and the willingness to double down on what's working.
This is the centrepiece of the episode. Bhanu explains that he built approximately 50 free tools — things like a PDF-to-Markdown converter and an AI chatbot name generator — each chosen specifically because the people likely to use it are also potential SiteGPT customers [1] — Bhanu "90% of SiteGPT's Google search traffic comes not from the main product but from ~50 free tools Bhanu built. Each tool targets a low-competi…" 10:35 . He gets around 50,000 clicks from Google per month, and roughly 90% of that traffic is driven by these tools rather than the main product landing pages [2] — Bhanu "60 to 70% of traffic is from Google, and in Google, like almost 90% of Google's traffic is from these free tools that we made." 04:40 . The key insight is alignment: every tool must be adjacent enough to SiteGPT's core offering that the user it attracts is a plausible paying customer. Bhanu then reveals the AI-era advantage: with Cursor, he can now build a new tool in under five minutes by pointing the AI at an existing tool template and specifying the target keyword. What was once a multi-day build is now a lunch-break task.
Mid-interview, Pat breaks away to pitch the Starter Story Build Bootcamp — a structured program designed to help aspiring founders build and launch their first app using AI tools. Pat ties the pitch directly to Bhanu's story: Bhanu's strategy only works if you can build things, and now AI has made building easier than ever. He offers a discount code — BHANU — at checkout, framing the bootcamp as the next logical step for anyone motivated by the episode. The promo is brief, focused, and contextually relevant rather than a jarring interruption.
After the playbook walkthrough, Pat asks about Bhanu's tech stack and monthly costs. Bhanu rattles off a 12-tool setup: Ahrefs for SEO and keyword research, SiteGPT itself for customer support on his own site, Cal.com for scheduling customer calls, Datafast and PostHog for analytics, Sibyl AI for call recordings, Bento for email marketing, his old product Feather for blog writing, Featurepace for feature requests and bug tracking, Mintlify for documentation, Cloud Code for AI-assisted coding, and ChartMogul for subscription revenue analytics. It's a deliberately lean stack — no bloat, all utility — and the fact that one person runs all of this while maintaining $13K MRR is itself a testament to how far AI tooling has shifted the solo-founder ceiling.
This chapter captures Bhanu's most actionable contribution to the episode. Asked to give a step-by-step playbook for founders starting from scratch in 2026, Bhanu outlines seven steps. Step 1: open Ahrefs Keywords Explorer and search with a blank query to surface every possible keyword. Step 2: apply include filters using terms relevant to your product category (e.g. 'AI' + 'generator'). Step 3: filter by keyword difficulty below 10 — the threshold below which any decent website can realistically rank. Step 4: add a minimum monthly search volume of 1,000 to ensure the traffic is worthwhile. Step 5: export the surviving keywords into a Notion page with volume and difficulty columns. Step 6: design a CTA for each keyword that naturally bridges the free tool to the main product. Step 7: score every opportunity by volume, difficulty, build effort, and product relevance, then prioritise accordingly. The playbook is immediately executable by any founder with an Ahrefs account [1] — Bhanu "Start with a blank Ahrefs search, layer in keyword filters (include term, KD < 10, volume > 1,000), list candidates in Notion, design a CTA…" 15:27 .
The episode closes with the perennial Starter Story question: what advice would you give your past self? Bhanu's answer is sharply pragmatic — stop over-engineering, launch the core feature as soon as possible, and let real users tell you what to build next [1] — Bhanu "I would not spend months and months on launching something. I would say just launch with a very core feature of your product and then let u…" 13:48 . Pat riffs on the broader theme: if you hate marketing and struggle with it, the answer isn't to grind through cold emails and content calendars — it's to lean into the thing you're already good at, which is building, and find a marketing approach that flows from that skill. A co-host chimes in to highlight the AI angle: the fact that Bhanu can spin up a new SEO tool in five minutes changes the calculus entirely compared to just a few years ago. Pat closes with a pitch for the 4x4 bootcamp — four side-project tools in four weeks — and thanks Bhanu for the unusually transparent look inside a real, growing indie business.
