Founder Track Record

Building the infrastructure behind India's largest EV battery-swapping network

Before founding Aesphire, we were among the first tech team members at Battery Smart, taking the MVP from system design to production deployment, shipping a six-application product ecosystem, and building the IoT infrastructure that scaled to over a million connected devices. This is the engineering DNA behind everything Aesphire ships.

20 Institutional investors, incl. Tiger Global & Orios

Context

First engineers, zero infrastructure

Battery Smart is India's largest EV battery-swapping network: drivers of electric two- and three-wheelers swap depleted batteries for charged ones at partner stations in minutes. The company is backed by 20 institutional investors — including Tiger Global Management and Orios Venture Partners — and its technology has carried it to a valuation of $340 million.

When we joined as one of the first tech team members, none of that infrastructure existed. There was no platform team, no DevOps function, no data team — every layer of the stack had to be designed, built, and operated by the same few people.

The Problem

An IoT firehose, and everything to build from zero

Six audiences, one platform. Drivers, station partners, ground operations, head office, external fleet clients, and support teams each needed their own purpose-built application — from day one, not someday.
Every hat, every layer. Frontend, backend, database, and DevOps infrastructure all had to be stood up from scratch — the kind of end-to-end ownership a developer in a large team never has to take on.
Telemetry at fleet scale. Batteries and stations stream continuous IoT telemetry. Naively writing that firehose to a database crushes it as the fleet grows.
Reads compete with writes. Operations dashboards, driver apps, and internal APIs all need large concurrent reads over that same data — without degrading ingestion.
No room for rewrites. A fast-growing network can't pause for re-platforming; the architecture had to absorb 10x growth without being rebuilt.

The Build

From system design to production: a six-application ecosystem

The MVP wasn't an app — it was a network. Every stakeholder in a battery swap needed their own surface, and each one was designed, built, and deployed to production:

Driver App The swap in every driver's pocket — take swaps, maintain the wallet, and view complete swap history. Every transaction on the network flows through it.

Partner Station App Revenue tracking for partner stations, plus battery authentication and verification tech that makes every swap at the counter secure.

Ground Operations App System integrity in the field — receiving batteries from OEMs, scanning and onboarding every asset, asset reconciliation and tracking, station audits, and health reporting as batteries move through the network.

HQ Ops Portal Central command for the operations team — network-wide visibility and control over stations, assets, and day-to-day operations from head office.

Client Fleet Portal For fleet clients like Zomato and Zypp — rider history, usage data, and account management for the fleets running on the network.

Support Ticketing System An in-house ticket management system — raising, routing, and resolving customer queries, with the analysis to catch recurring issues before they scale.

Six applications, each shipped to production and used daily to run the network — built by a team small enough that every engineer owned entire products, not features.

The Infrastructure

End-to-end ownership of the full stack

Underneath the product suite, we set up the complete platform end to end — frontend applications, backend services, the database layer, and the DevOps infrastructure to deploy and operate all of it — choosing the right tool for each problem rather than a single fashionable stack.

IoT Fleet 1M+ batteries & stations emitting telemetry

→

Ingestion Layer Write path shaped to absorb telemetry bursts

→

Storage Design Structured to keep DB stress low as the fleet grows

→

Retrieval Paths Concurrent large reads for dashboards, apps & APIs

Telemetry storage that protects the database. IoT data storing and retrieval designed specifically to reduce stress on the DB while serving concurrent large data requests — ingestion and queries don't fight each other.
Full-stack, any stack. Years of wearing multiple hats built the ability to stand up frontend, backend, database, and DevOps infrastructure for any kind of application, using whatever technology the problem demands.
Built to be operated. Deployment, monitoring, and recovery were part of the design from day one — infrastructure the team could actually run, not just launch.
