Velocity SaaS Platform

B2B startup launching field service product

The Challenge

Velocity, an early-stage startup, wanted to enter the field service software market. They needed to launch a robust, multi-tenant software-as-a-service (SaaS) application complete with client dashboards, field staff scheduling, automated payments, and a mobile app. With investor milestones looming, they had a strict 12-week deadline to build this full-scale platform from scratch.

Our Custom Solution

SystemGrid deployed a dedicated agile team to develop the Velocity SaaS foundation. We built a secure multi-tenant web application featuring Stripe billing cycles and tier management. We developed high-performance REST APIs using NestJS and a cross-platform mobile app using React Native for field workers to manage tasks, capture customer signatures, and sync updates in real-time.

The Outcome & Impact

Velocity launched their MVP right on schedule in 12 weeks. The startup acquired 50 paying B2B customers in their first month. Our clean microservices architecture and cloud setup successfully supported their growth, handling a 10x increase in user transactions with zero downtime or database bottlenecks.
