Next Street, a New York-based firm that designs and develops solutions to connect entrepreneurs and small business owners with the right resources at the right time, gave us an idea for a multi-tenant Software-as-a-Service platform that needed to be built from the ground up adhering to security protocols.
Client: Next Street
Location: USA
Industry: Business consulting
Team Size: 9 team members
Project Duration: 13 month
Next Street aims to connect small business owners in any market sector to easily navigate and connect directly to the best-in-class national and local resources they need to grow revenue, hire talent, and build wealth. The platform can be customized and built to help clients coordinate their small business ecosystem, run programs, support growth sectors, and/or build the capacity of diverse suppliers.

Let's discussThe development process, although similar to outsourcing, involves constant interaction with the customer. Although the client had a design at the start of the project, changes were necessary during development. Our designers collaborate closely with the client’s team to promptly enhance the existing UI/UX and add new features.
From the beginning, we worked with the requirements, delving deeply into the concept and business cases, identifying any inconsistencies, and finding more natural and elegant solutions to problems.
This close collaboration has grown into a long-term partnership, supporting multiple major launches across the U.S., including New York City, a leading U.S. telecom provider, and most recently, Los Angeles.
NestJS is based on Express.js, which is recognized for its scalability. This was essential for our application since we expected a growing user base and required a framework capable of effectively handling increased traffic and data volume.
React is ideal for creating dynamic and responsive user interfaces. Its component-based structure promotes code reusability, which significantly accelerates the development process.
We implemented Continuous Integration and Continuous Deployment (CI/CD) pipelines to automate the build, test, and deployment processes. The automation reduces manual errors, ensures consistency, and accelerates the delivery of new features and updates.
PostgreSQL was selected for its robust data integrity features. It supports constraints, triggers, and foreign keys to ensure the accuracy and consistency of our data. This is crucial for an application that handles sensitive user information.
We selected Amazon Relational Database Service (RDS) Aurora for its exceptional performance. It offers up to five times the throughput of standard MySQL databases, essential for our app to efficiently handle a potentially large user base and complex queries.
Small business owners can obtain loans, credits, and grants to start or support their ventures.

It was initially launched with the NYC Department of Small Business Services and has since expanded to serve other major clients, including a leading U.S. telecom company and, most recently, the City of Los Angeles in April 2025. This latest launch supports local business growth ahead of global events like the 2028 Olympics, reinforcing the platform’s value in driving regional economic development.
