About Us

We are your advisors, not consultants. People who are not afraid to get shovels in their hands to dig into your data and your environment to provide you with the best results. Our priority is to help you solve your problems and we are on the mission to change how typical consulting services are delivered.

What is Sargable

Sargable is a derivation of Search Arguments and is a condition in relational databases where the query can take advantage of the index to speed up execution. Saying the query is non-Sargable means it’s inefficient, using too many resources and taking too long. We want to help make your business “Sargable” and use data more effectively across its entire lifecycle, as it’s all too easy for data to become the equivalent of non-sargable.

We only work with technologies that follow our ethos and make your data available without locking you into proprietary technology or service.


Over the past years, we have delivered many data-related projects, from simple server builds, logical data modelling, and physical design to complex data migrations and integrations. We have seen and dealt with many obstacles. Still, the most common was data availability, getting and consolidating data in a compliant manner, and finding the common denominator to make sense of it.

After many years of employment and contracting in different industries, in 2016, we started a company helping businesses manage their Microsoft Data Platform solutions. In 2020, we decided to expand and rebrand to respond to the changing market needs and help our clients use their data. We created the Sargable Group. It reflects what we do and how we feel about it.

Being a small, cost-effective company allows us to give our customers the flexibility, attention and focus they require.
