Y~SI Partners
Entrepreneurial responsiveness

& Corporate Quality Standards

Y-SI is a small practice that brings the lean responsiveness of an entrepreneurial attitude to larger companies. We intercede to solve problems quickly and effectively.

Size matters: we are nimble in scale, but our large network of highly specialised professionals allows us to tackle projects of all sizes across several disciplines without compromising speed. Our partners work independently but can assemble a team overnight; a man or an army, you decide.

Old dogs with new tricks: all of our partners have 10 to 15 years of international experience working for industry leaders across a variety of business lines, and have a deep understanding of what leads to successful outcomes for your project.

Areas of Expertise

Brand, Marketing & Communications

The practice offers a range of services covering management consulting, planning and execution across every channel, including social media, and digital video.

Project & Programme Management

Our partners have experience working on multi-party complex scenarios, with an impeccable track record of delivering above and beyond expectations. Our partners are certified with international project management bodies.

Software Architecture & Development

Our team's solid technical skills seamlessly complement a focus on our clients' business. The practice's approach puts the client's goals first, seeing technology as a way to deliver solutions.
