Founder · Anextera Technologies
I build technology and marketing as one system, not two departments — as Founder of Anextera Technologies. I run New India Social Welfare Foundation with the same discipline, because good work shouldn't stop at the P&L.
AI, data, marketing, and product thinking — applied to real business outcomes, not vanity metrics.
Core Philosophy
Impressions and engagement rates are inputs, not results. Every strategy is judged by what it does to the business, not what it does to a dashboard.
AI speeds up execution — it doesn't replace judgment. Every automated workflow sits on top of fundamentals that were true before AI and will outlast the current hype cycle.
Every strategy is personally led. No pitch-then-disappear — the person who scoped the work is the person doing it.
Helping businesses achieve measurable growth through data-driven marketing is the goal — not a single campaign, but a partnership that compounds.
About
Karthikeyan Srinivasan is a Chennai-based technology founder working at the intersection of digital marketing, analytics, and applied AI. He founded Anextera Technologies to bring performance-driven marketing — SEO, paid media, and marketing analytics — to businesses that have outgrown guesswork.
Alongside his commercial work, he directs the New India Social Welfare Foundation, an NGO focused on education, healthcare, and community development.
Read the full story →Founder Journey
An engineering background, time spent understanding trading and markets, and a serious interest in photography — three disciplines that all teach the same thing: pay attention to the signal, not the noise.
That eye for signal moved into digital marketing — SEO, paid media, and analytics — alongside early social initiative work that would later shape NISWF.
Founded to combine AI and marketing as one system rather than two disciplines bolted together — built around measurable growth, not guesswork.
Formalized years of social initiative work into a foundation focused on education, healthcare, and community development.
Building one of India's leading technology companies, creating AI products with global relevance, and staying involved enough in social impact work that it never becomes a side project.

Community Impact
As Director of the New India Social Welfare Foundation, I lead CSR partnerships and social welfare programs across education, healthcare, and community development.
In June 2026, NISWF supported a modest educational assistance initiative — around ₹50,000 directed toward underserved students — the kind of quiet, recurring work the foundation focuses on rather than one-off gestures.
