Co-Founder & CTO, FlexiFunnels

I build the systems
that let entrepreneurs
sell online — and run it — with AI.

Chennai-based engineer and co-founder. For the last five years I've architected FlexiFunnels from the ground up alongside a core team that's stayed with me for over a decade — now scaling into FlexiAgent, a workforce of AI agents that runs a business's operations end to end.

About

Engineer first. Operator by necessity.

Karthik Ramani

I've spent over a decade building and scaling software, the last five of those as co-founder and CTO of FlexiFunnels, an all-in-one platform that helps entrepreneurs build websites, sales funnels, and online courses without writing a line of code. I lead all technical architecture and execution, with a core engineering team that's been with me for ten-plus years, which is rare in this industry and something I'm genuinely proud of.

Before FlexiFunnels, I ran Jargon Handlers as CEO and Director for thirteen years. That stretch taught me how to build and operate a business end to end, not just ship code, which is a big part of why FlexiFunnels has stayed bootstrapped and profitable since day one.

I'm a serial entrepreneur at heart: alongside Jargon Handlers and FlexiFunnels, I've co-founded Everlesson, one of the most trusted online learning platforms, and launched an educational startup teaching STEM through robotics, plus a handful of other software products aimed at helping small businesses generate more leads and sales.

Outside the architecture diagrams, I negotiate hard, I speak at marketing conferences worldwide, and I'm currently relearning how to sing. More on that below.

What I'm Building

Two products, one mission.

FlexiFunnels

An all-in-one, no-code platform for websites, funnels, checkout, and course hosting, built so entrepreneurs stop stitching together ten separate tools to sell online.

Beyond Work

A few other things worth knowing.

Negotiation

I rarely pay list price. My default is to build rapport with a real person, show the value I bring, and negotiate custom terms, most recently landing an NVIDIA RTX PRO 6000 Blackwell Max-Q GPU at 50% off the published rate.

Speaking & Marketing

I've presented live to audiences of 3,000+ and been an influential keynote speaker at email marketing conferences worldwide, and ranked as a top-10 affiliate on JVZoo for five consecutive years helping businesses sell via email, webinars, and seminars.

Voice & Singing

Over the past year I've resumed singing and voice training and started performing at smaller live events, learning a completely new skill from scratch as an adult.

Badminton

I play local badminton tournaments and have been consistently performing better each season.
