Despite many successful software development outsourcing cases by large companies, many startups hesitate to outsource app development due to concerns about trust and delivery. However, the experience of some startups shows a different reality. Here’s an overview:
Slack
To save raised funds, Slack, a real-time office collaboration tool, outsourced its design and mobile app development services from the very beginning. With the help of an outsourced workforce, the company gained 15,000 users within two weeks of launch. Later, Slack became a unicorn in 2014.
WhatsApp
In 2012, WhatsApp was a small organization with only 30 full-time employees and five part-timers. The company started with just $250,000 in capital raised during the seed round. To keep costs low and access skilled developers at a reasonable price, WhatsApp turned to Eastern Europe—one of the biggest outsourcing hubs.
This decision allowed WhatsApp to leverage quality tech talent for development. Today, WhatsApp is a global messaging giant and a crucial part of Meta’s ecosystem, contributing significantly to Meta’s overall valuation and revenue.
GitHub
GitHub, the popular platform for version control and collaboration, relied on an outsourced team during its early development stage. At the time, the founders did not have internal engineering support.
By outsourcing key development work, they were able to launch a stable product quickly. This early success helped attract users and secure funding. GitHub later became an essential tool for developers worldwide.
Alibaba
In its early days, Alibaba outsourced website development to a U.S.-based team. Jack Ma needed a functional and accessible site for global users. This required expertise that was not easily available locally.
Outsourcing helped Alibaba meet global standards in the early phase without overstretching its in-house capabilities. The company eventually grew into one of the world’s largest e-commerce platforms.
TransferWise
TransferWise, now known as Wise, used outsourcing to build the backend of its money transfer system. The co-founders did not have the technical resources to create secure and compliant infrastructure.
Offshore outsourcing allowed them to launch a working product quickly, test it with real users, and make improvements without hiring a large internal tech team. Today, Wise is a trusted platform for international money transfers.
CitiGroup
In 2014, Citi cut 11,000 jobs at its headquarters, including at least a quarter of its IT specialists. The goal was to bring these roles offshore and reduce development cost. This move quickly saved the company $1.1 billion per year.
Although Citi is a large corporation, its strategy mirrors what many startups aim to achieve: cost reduction and access to skilled talent without increasing local overheads.
By outsourcing IT functions, Citi maintained service quality, improved efficiency, and allowed in-house teams to focus on critical financial operations. The shift helped Citi stay competitive during a challenging market period.
