How it All Began

Founder and CEO, Sergey Poltev, has been fixing computers since he was 12 years old, when his first computer blew up. He saved money from his pocket allowance to buy parts to rebuild and fix the early model PC. That began his fascination with computer technology.

This later inspired him to follow his passion to University. He received a Russian National Scholarship and completed the degree of M.Sc. in Computer Science with Honors.

Teenage Tech Entrepreneur

At the age of 18, Sergey opened a successful internet café / PC gaming studio in Russia with two teenaged business partners. His initial goal was to earn enough money to buy a cell phone. At that time, internet access from one’s home was financially out of reach for most people in Russia. The demand for internet café services was strong so this resulted in a successful enterprise.

Sergey quickly saved money for a cell phone. Two years later, he sold his share of the business in order to pay for the cost of a University exchange program that allowed him to study in the US for an academic year.

New Immigrant

Sergey launched CALLGEEK (later renamed to CapitalTek) in 2008. He had recently immigrated to Canada to seek new opportunities and like many immigrants, he couldn’t find a job despite having strong academic credentials. 

As a newcomer to Ottawa in his mid-twenties, he had no business contacts, no startup funds and spoke very little English. Despite these obstacles, he was determined to succeed in his new home country, so he started a computer services company from scratch. To find his initial clients, he walked door to door in residential areas of Ottawa and placed his brochure in mailboxes. 

Startup of CapitalTek

In 2010 Business started to grow with addition of Proactive Maintenance, Monitoring and Backup Services. Sergey Incorporated the business, expanded Offices, hired first staff, and did major rebrand (renamed CALLGEEK to CapitalTek) to attract business customers. This Brand continues to bring awareness today. Company Established good presence here as one of the Top IT service providers in Ottawa 

From these early stages of CapitalTek and continuing to this day, Sergey has always gone “over & above” with customer service and always tries to exceed expectations. This customer-focused approach showed results in the early stages of the firm. After he was able to acquire a few clients, the referrals came in quickly. Referrals continue to be a major source of new clients. 

Expansion with Computer troubleshooters 

At the end of 2021 CapitalTek Acquired Computer Troubleshooters – Orleans, the only Computer Troubleshooters franchise in Ontario, specializing in affordable Small Business IT Services was part of Computer Troubleshooters international network of locally-owned and operated IT service franchise offices launched in 1999. Since 2004, Computer Troubleshooters – Orleans has provided small Business and residential clients with Remote and Onsite IT support, IT Services, Computer diagnostic, Backup and Security Services to Over 1,000 Customers in Ottawa.
