Sunbytes

Sunbytes is a Vietnam-based software development and HR services firm. The company has been operating for over a decade and won FD Gazelle awards in 2023 and 2024, which recognize fast-growing private companies in the Netherlands. Sunbytes markets itself to clients across Europe and beyond, offering four core service lines: custom software development, dedicated technical resources, cybersecurity services, and HR solutions tailored to Vietnam operations.

Services and capabilities

Sunbytes' custom software development practice covers a broad technology stack including PHP, Ruby on Rails, Java, JavaScript, Python, Go, C#, React, Next.js, WordPress, and Symfony. The company emphasizes technical consultation with quality assurance and claims expertise in specialized sectors such as IoT, fintech, and healthcare. Code review and penetration testing are offered as part of a broader cybersecurity portfolio. For infrastructure and operations, they list DevOps capabilities.

The dedicated resource model lets clients hire developers or full agile teams on flexible terms, starting from a single full-time equivalent (FTE) that can be split across multiple disciplines. Team formation is based on what the company calls "comprehensive examination" of client software development needs. According to Sunbytes, teams can scale quickly by drawing from their network of local and global talent.

On the HR side, Sunbytes offers payroll administration, employer of record (EOR) services, and IT and talent recruitment. The company positions these as ways to simplify operations in Vietnam and access top IT expertise in that market.

Notable work

Sunbytes names four clients with quotes. Methodemeter, a product company, engaged Sunbytes for penetration testing; the Methodemeter product manager noted the "thorough" approach and said it "uncovered risks we'd never even considered." TeamViewer, the remote connectivity platform, worked with Sunbytes across multiple project phases and cited their "in-depth knowledge" in helping make strategic decisions. DieWertschöpfe (referenced as DWS in the case study) praised the ability to work with "flexible well-trained developers without losing control over the project, scope, and impact." Flexpress, a site management platform, described Sunbytes as "critical" to their development as they scaled from a single site to a wider portfolio.

How they work

Sunbytes requires all staff to sign NDAs before starting work. The company touts cost transparency and positions itself as offering "best value as a Tech&Talent provider." They accept inquiries through a web form and promise to respond "right away" with proposals tailored to stated requirements. Pricing details are not disclosed on the public website; this appears to be handled in direct conversation.

Team and credentials

No specific founder names, total headcount, or office locations are listed in the source material. The company holds FD Gazelle recognition for 2023 and 2024. They advertise on Clutch and reference case studies there, but no specific Clutch rating or review count appears in the source. No ISO, SOC 2, GDPR, HIPAA, or other compliance certifications are mentioned. No partner badges (AWS, Microsoft, Google, Shopify) are listed.

A note on the source material: The scraped content is dominated by cookie consent declarations and form HTML, with limited substantive detail about the company's operations, team structure, or track record. Much of Sunbytes' marketing language on the site uses the kind of phrasing the editorial guidelines flag as generic ("comprehensive," "flexible," "tailored"). The entry above strips those out and relies on the few concrete facts present: named clients, the stated tech stack, the service categories, and the FD Gazelle award years.
