Overview
Our client is a sales tech startup that helps companies book better sales meetings. To do that, their team needs a steady flow of good leads. But finding those leads wasn’t easy. Building a lead list was a lot of work for the team, requiring them to switch between different tools.
So we built them a simple web app that does all of it. The team signs in with their Google account and searches for new leads and the app fills in the missing details on its own. Once they have the list ready, they can send it directly to Google Drive with a single click. They also get to see what the entire team is working on. And as the business grows, the platform can grow with it.
What were the Challenges?
The client’s team was juggling multiple disconnected tools just to build a single lead list. You’d get prospects from one place, validate email addresses from another, and organize your findings from somewhere else. That meant a lot of manual work and lead data that wasn’t always consistent.
They needed one platform that could automate data enrichment, give visibility into what the whole team was working on, and integrate into the sales workflow they already had. And since they’re a startup with big plans, security and room to grow were must-haves from day one.

Scalable Frontend & Backend Architecture
How Did We Operate?
We started by learning how the client’s account managers actually build lead lists day to day. Instead of pushing their team into an off-the-shelf tool that would limit them, we designed the platform around their real sales process. That kept things simple for the people using it every day.
The client worked with a dedicated full-stack developer from JS Panther for the entire project. A developer who only worked on their platform kept things going steadily. It also helped us understand the product and business quickly, adjust to changing requirements, and keep delivery moving.
For the frontend, we used React and TypeScript to make it fast and reliable, and for the backend, we used Node.js and MongoDB. We integrated the Coresignal API for lead discovery, the Hunter API for email enrichment, and GenderAPI for further data enrichment. Google Workspace OAuth 2.0 handles secure sign-in, and the Google Drive integration sends finished lead lists right where the team already works.
Results
The sales team now spends less time on busywork and more time actually selling. They build lead lists in one place, and the app fills in the blanks for them, rather than navigating around tools. Fewer errors and cleaner data, every time.
It’s also easier for the team to work together. Everyone can see what’s going on, so nobody’s guessing who’s working on what. And since we built the platform to grow, adding new features down the road is simple. The client got a tool that works for them today and is ready for whatever comes next.
