About Upstack
Upstack, founded in 2010 by Yossi Mlynsky, operates as a network for hiring remote software engineering talent. The company began as a bootstrapped startup headquartered in New York, and it connects businesses with pre-vetted developers from a global network of over 4,000 senior-level engineers. Yossi Mlynsky, a seasoned engineering and product manager with previous roles at Macquarie Bank and Monster, founded Upstack to address the challenge fast-growing companies face in finding top engineering talent. His background in scaling teams and products directly informs the company's mission.
The business model centers on simplifying the process of building remote software teams. Upstack provides an all-in-one platform that handles vetting, onboarding, payments, and compliance, allowing clients to focus on their core product development. Companies work with Upstack's experts to create a personalized hiring plan, and the platform then matches them with suitable engineers. This service aims to reduce talent costs by up to 40% and increase talent retention rates. Upstack serves a range of businesses, from SaaS startups to mature IT firms, helping them scale their infrastructure, modernize internal systems, and manage technology spending.
Upstack's core service is providing access to a curated pool of senior developers specializing in modern frameworks like React.JS, AI, and DevOps. The company's vetting process assesses candidates for technical expertise, communication skills, and cultural fit to ensure they align with a client's team values and mission. Beyond simply matching talent, the platform manages administrative tasks such as global payments and compliance, which can save clients significant administrative overhead. The company offers a human-centered approach with dedicated support and regular check-ins to facilitate a smooth integration of remote talent into existing teams.
