In this episode of The Nikhil Sai Show, host Nikhil Sai interviews Karthik Nairu, founder of StartYourSaaS.io (and its development arm Infinext). Karthik recounts his decade‑long entrepreneurial path, beginning with a preschool franchise, pivoting during COVID‑19 to coaching and digital marketing, discovering GoHighLevel, and ultimately building an Indian‑focused all‑in‑one SaaS platform for agencies. He explains his conviction in recurring‑revenue models, the strategic decision to avoid lifetime deals, the importance of deep team ownership, hands‑on product development using AI‑assisted coding, and a customer‑centric onboarding model that replaces free trials with a 3‑month intensive program and dedicated WhatsApp support. Karthik also shares his bootstrapped financial philosophy, marketing budget discipline, future plans (no immediate fundraising, focus on profitability and strategic partnerships), and practical advice for aspiring SaaS founders about risk, urgency, and leveraging AI. The conversation weaves together themes of resilience, product‑market fit for Indian agencies, the AI‑SaaS revolution, and leadership lessons.
