A one-person studio. I build websites that convert, automations that recover lost revenue, and AI that scales it — from code, not templates. Done with US & AU service businesses.
Most businesses bolt on tools that don't talk to each other. I build the layers as one stack — so the site feeds the system, and the system feeds the scale.
Start your stackEditorial, fast, conversion-first. Built from code so they outclass every template competitor in your market.
Every missed call gets an instant, time-aware text-back and a logged lead. Stop money walking out the door.
After-hours calls answered by AI, booked automatically. Your front desk that never sleeps.
Custom systems that surface qualified local leads and route them straight to you — so the top of your funnel is never empty.
Client builds and the systems behind them — click any for the full story.
HVAC site redesign — from a 3/10 broken site to a 9/10 conversion machine.
Automation that text-backs every missed call & logs the lead. ~$20–70k/yr recovered.
A lead-generation system I built end-to-end — finds, enriches, scores & routes qualified local leads. Sample data shown.
A 24/7 voice agent that answers every call, triages emergencies, books jobs & logs every lead — sounds human, never sleeps. Working demo build.
I'm Santhosh — 23, based in India, building GrowthStack as a one-person studio. Web, automation, and AI under one roof, so the layers actually fit together instead of fighting each other.
Before this I ran Cyberfreaks, a non-profit that brought cybersecurity awareness to 1000+ students across Tamil Nadu. That security mindset is why I build from code, think about what breaks, and treat your data and uptime like they're mine.
I study how the sharpest operators in sales, growth, and automation actually work — then I cut the theory and build only the parts that move revenue into systems made for your business. You get the compounding effect of that obsession, without the years of trial and error.
