About

I'm Arihan, an IB Diploma candidate at Shiv Nadar School, Gurugram, taking Economics, Mathematics: Applications & Interpretation and Computer Science at Higher Level. I build at the intersection of business and music.

I founded Zenth, a digital agency working with two clients on recurring monthly retainers, and The Floor, a self-discipline app built on one idea: one promise a day, kept or broken, with no edits. Alongside that I've worked as an AI intern at Panscience Innovations, building a meeting assistant with real-time transcription and an AI avatar video-call feature, and as an analyst intern building predictive models for equity price outcomes.

Outside of that I'm a multi-instrumentalist, producer and vocalist, I represent teams in business simulations and Model UN committees, and I teach entrepreneurship and economics with community projects. I'm driven by the process of solving problems — breaking down complex challenges, exploring different approaches, and turning ideas into things that actually ship.
