Why organizations choose us
Toptal in Action
Discover the cutting-edge benefits our clients enjoy from the global Toptal network.
Toptal empowers national food and beverage company’s foundation with a scalable web app.
Challenge: The foundation provides meals to schools across the United States, supporting nutrition programs for children in need. But the application it was using to manage orders and deliveries was outdated, a problem that was exacerbated by the absence of a dedicated tech team.
Solution: Toptal assembled a specialized team to build a comprehensive web application from scratch, centralizing the management of clients, meals, orders, and deliveries. Using Agile methodology, Toptal prioritized and implemented features rapidly, ensuring fast deployment and scalability to meet the foundation’s growing needs.
Outcome: The foundation’s operational efficiency surged, resulting in a 200% increase in the value of orders processed, from $5 million in 2022 to $15 million in 2023. With the new solution in place, the foundation could manage orders more effectively without additional staff, ensuring long-term operational sustainability and better service to kids and communities.
