Retail Mumbai, Maharashtra 11–50 employees Founded 2018 Privately Held

Tohands builds a smart calculator device paired with backend services for Indian shopkeepers—a hardware-SaaS hybrid targeting a cash-heavy, offline-first merchant base. The tech stack reveals a mature embedded systems approach (ARM, FreeRTOS, U-Boot, JTAG) alongside modern cloud infrastructure (AWS EKS, Lambda, PostgreSQL, DynamoDB), indicating serious engineering depth. Pain points cluster around offline distribution scaling and backend performance, while active projects span both hardware onboarding and merchant acquisition—suggesting they're at a transition point from product-market fit in a niche toward scaling distribution and sales operations.

About Tohands

Tohands develops a smart calculator device and accompanying SaaS platform designed for small retail shopkeepers in India to track income and expenses. Founded in 2018 and based in Mumbai, the company bridges hardware (embedded Linux, ARM-based devices) and cloud services (AWS-hosted APIs for payments, device sync, and offline data reconciliation). The product targets merchants operating in low-connectivity environments where traditional software adoption is constrained by literacy, internet reliability, or device costs. The team of 11–50 is engineering-heavy with growing marketing and sales functions, currently hiring across India.
