This Founder's $13k/mo AI Stack

Bhanu isn't just another founder; he's a proven operator with two profitable SaaS products under his belt. He grew one product to $6,000 MRR before selling it for a substantial $250,000. His current venture, **SiteGPT** — an AI chatbot platform that transforms website content into an always-on AI assistant for customer support — launched as a two-week MVP and swiftly scaled to $13,000 MRR.

His growth engine isn't complex ad campaigns but a strategy he terms engineering as marketing. Bhanu builds dozens of free tools, around 50 by his count, specifically designed to attract highly targeted organic traffic. These useful, no-cost resources serve as a potent, scalable lead generation mechanism, converting curious visitors into potential paying customers.

This isn't random development; it's a calculated approach. Bhanu leverages Ahrefs beyond typical SEO uses. He meticulously identifies low-competition, high-volume keywords that directly inform his free tool ideas. This data-driven insight creates a robust, self-sustaining customer acquisition flywheel, consistently funneling relevant users towards SiteGPT and its AI capabilities.

After SiteGPT's quick rise, Bhanu applies his own product to his business, effectively "dogfooding" it. He uses SiteGPT for website support, transforming his site's content into an AI assistant that handles user queries. This isn't just a sales pitch; it's a practical demonstration of SiteGPT's ability to provide always-on, AI-powered help, reducing the need for manual support and ensuring prompt answers for his customers.

Beyond automated answers, Bhanu meticulously streamlines customer interactions. He schedules calls with customers using cal.com, a straightforward booking tool. During these calls, he leverages **Sybill AI to not just record but also analyze conversations, extracting valuable insights. For ongoing engagement and targeted follow-ups, he deploys Bento**, ensuring users receive relevant email communications tailored to their needs.

Crucially, Bhanu prioritizes a robust feedback loop for continuous improvement. He uses Featurebase to systematically collect feature requests and bug reports directly from his active user base. This dedicated platform centralizes user input, turning qualitative feedback into actionable development tasks and validating the investment in a structured approach to product evolution.

Bhanu’s AI stack isn’t just for customer-facing tools; it powers his entire development and content engine. For coding, he relies heavily on **Claude Code**, using the AI as his primary partner for writing and iterating software. This isn't just about speed; it’s about efficiency for a founder managing multiple products.

Content creation for SiteGPT and his other ventures also leverages AI. He uses his previous SaaS product, **Feather**, to streamline his blog posts. Feather takes raw ideas from Notion and transforms them into SEO-optimized articles, a critical step for driving organic traffic and maintaining an active online presence. This integrated approach ensures consistent, high-quality content without a massive time investment.

Finally, proper documentation is non-negotiable for a modern SaaS product. Bhanu chose **Mintlify** for his docs, specifically for its developer-first and AI-native features. These tools collectively underscore a strategy where AI isn't just a feature, but a foundational element of operations, from code to content, ensuring products like SiteGPT - Make AI your expert customer support agent are well-supported and explained.

Understanding exactly how users engage with his products is paramount, and Bhanu avoids guesswork with a robust analytics duo. He deploys PostHog and Datafags to gather deep, actionable insights into product usage and granular user behavior. This isn't about vanity metrics; it’s about dissecting every click and conversion point to truly see what resonates with customers and where improvements are needed.

Yet, usage data only tells half the story without the financial readout. ChartMogul steps in as the mission-critical, single source of truth for all subscription analytics. It meticulously tracks the health of his revenue streams, providing precise figures for Monthly Recurring Revenue (MRR), Annual Recurring Revenue (ARR), and, crucially, churn. This direct line to financial performance means he always knows the exact pulse of his business, without needing to manually cobble together reports.

This entire, meticulously constructed data stack isn't just for show; it's the bedrock of Bhanu's core philosophy: transparency and tangible results trumping fleeting hype. He doesn't rely on gut feelings or industry buzz, instead using these precise tools to measure every dollar generated and every user interaction, enabling truly informed business decisions. For a founder who's achieved a substantial exit and is rapidly scaling SiteGPT, knowing your numbers isn't just smart—it’s the only way to build a sustainable, profitable SaaS enterprise.
