Silxo is a discreet professional services company that specialises in supporting businesses with their technology and business decisions, directions, and developments to achieve accelerated growth and success.

Silxo excel in supporting investors, family offices, governments, and other corporations, with a team that has significant experience across multiple sectors. We facilitate business transformation and technology innovation to achieve growth and operational efficiency.

Starting with our Discovery assessment services, Silxo has been successfully providing an end-to-end catalogue of technology, product and commercial realisation services to its Investor, Corporate and Public Sector clients since 2014.

Experience & Pace

Our team is former CXOs from large technology corporates, product companies and various industry sectors. As individuals and as a team, our Senior Partners know what it takes to open new markets, manage $1bn+ budgets, build multi-year products, expand into new locations, transform businesses, and lead people through change. We know how to do this in a language that the business understands, at pace, and without disruption.

Our Clients

Our clients, like ourselves, have seen many IT related projects and programmes. We have both advised and been advised. Experience can be generalised, but tends to conclude that when IT projects fail, the business feels disconnected and technology becomes expensive, holding back the business’s success.

Let us help you move past these generalisations and move towards effective delivery that is instep with your business’s growth plans.
