Bug Bounty Switzerland appoints Stefan Velikov as Head of Sales

Bug Bounty Switzerland has appointed Stefan Velikov as Head of Sales as of February 1, 2026. In this key position, Velikov will strengthen the management of the Swiss pioneer in security testing with ethical hackers. One of his most urgent tasks is to scale the sales team. This involves creating sustainable structures and reproducible processes within the sales organization to support the transformation of Bug Bounty Switzerland from a start-up to a scale-up company and its national and international expansion.

In this important task, Velikov can draw on his extensive know-how of complex sales processes as well as his wide-ranging network in the Swiss venture and start-up ecosystem. Stefan Velikov founded the company Viabz in 2017, which developed an app for workplace health promotion, and successfully scaled it until it was sold in 2022. Since then, he has been heavily involved in the Swiss start-up scene, including with the non-profit organization Swisspreneur. He has also built up the largest B2B sales community in Switzerland with the Sales Velocity Collective, which has been awarding the Swiss Sales Trophy for sales talent in the B2B software sector since 2025.

Supporting the next phase of growth and internationalization

Bug Bounty Switzerland can look back on a successful past year in which the company finally developed from a start-up to a scale-up. The Cyber Resilience Shield, an innovative security testing product launched in November 2024, played a major role in this. Velikov's task will be to further develop the existing sales team and multiply it by the end of 2027 in order to meet the high demand and generate further sales growth. At the same time, international expansion will now be systematically driven forward.

The establishment of an efficient and scalable sales organization with a clear set-up is the next step in the implementation of Bug Bounty Switzerland's vision: redefining security testing and positioning itself as a leading provider. «I see a rare combination of timing, talent and technology at Bug Bounty Switzerland,» says Stefan Velikov. «I am particularly excited to work with the team to build a scalable go-to-market organization and prepare the company for the next phase of growth and internationalization.»

«Stefan Velikov's strong drive, extensive network and vast experience in building scalable sales systems and high-performing teams make him the ideal fit for our scale-up,» says Sandro Nafzger, CEO and Co-Founder of Bug Bounty Switzerland. «Stefan joins us at a pivotal time - at a moment when we are transforming as a company and the way security testing is done in the age of artificial intelligence is changing.»

AI-supported platform for security testing

Bug Bounty Switzerland operates an AI-supported Swiss platform for data-driven security testing. The platform enables large companies and organizations to perform continuous, scalable and easily accessible security checks - always-on, self-learning and «plug and play». The core of the solution is the Cyber Resilience Shield: a virtual protective shield that combines the expertise of over 16,000 ethical hackers with threat intelligence and autonomous AI agents to uncover security vulnerabilities faster, more precisely and more efficiently than with traditional testing methods. The system continuously learns from each test result, refines its methodology and adapts security strategies in real time.
