UNRIVALED EXPERTISE

Our Talent Has Worked With Top Companies

Having previously worked with these leading global companies, our talent brings valuable insights and expertise to deliver world-class outcomes.

WHY ORGANIZATIONS CHOOSE US

Toptal in Action

Experience the cutting-edge benefits our clients enjoy from the global Toptal network.

Toptal helps leading investment advisory firm save an estimated $500,000 per year with API-first strategy.

Challenge: After a company restructuring, a leading investment advisory firm faced a shortage of technical expertise and a data integration strategy hindered by manual processes and outdated legacy systems. To stay competitive, the firm needed a customer-centric, data-driven solution to streamline client management and drive smarter, faster decision-making.

Solution: Toptal swiftly assessed the client’s current system and isolated issues with outdated management and unscalable peer-to-peer connections across their many apps. Leveraging Agile techniques to implement MuleSoft API, Toptal spent 18 months instituting an API-first strategy to replace old processes with automated, modernized solutions for 10 of the client’s applications.

Outcome: The new API-focused operating model saved the client 5,000 hours annually, valued at $500,000, while improving data consistency and reducing errors. By replacing peer-to-peer dependencies, Toptal’s solution enhanced functionality and created a scalable architecture for future growth.

Toptal worked relentlessly over many months for the successful launch of our new platform and MuleSoft capabilities.
