• Access to specialist partner companies: The Sourcing Hub maintains a vetted network of European technology vendors who collectively offer capabilities in Big Data, BI, Cloud, DevOps, Testing, and Database Management. Clients can access these specialised skills without individually searching or validating dozens of providers.
• Risk-reduced vendor selection: Their vetting criteria include technology stack capability, delivery maturity, financial stability, team experience and domain expertise. This lowers the risk for clients trying to find reliable partners for technical services outside their internal strengths.
• One-point management: Instead of managing multiple technical vendors across different domains like cloud, BI, DevOps, QA, clients work through The Sourcing Hub as a single coordination layer. This simplifies communication and engagement oversight.

• Faster sourcing for specialised roles: Technical skills like DevOps engineers, cloud architects or data engineers are hard to hire quickly. Their partner network allows faster access compared with direct recruitment.

A UK fintech startup reported:

• “We needed to scale our tech team quickly, and could not find the right people fast enough, so we considered outsourcing. The team at The Sourcing Hub was able to manage this whole process for us, and we have now been working very successfully with our Ukrainian partner for over 12 months.”

This indicates:

• The Sourcing Hub successfully sourced and managed a long-term external engineering team.
• The partner team supported the client’s technology operations over an extended period, which typically includes ongoing development, testing, cloud-related work or DevOps support in real-world outsourcing engagements.
• The results show that their vendor-matching and ongoing management model can sustain multi-service technical delivery for a live product in a competitive sector like fintech.

Unlike general IT consultancies that offer testing as an add-on, SDET Technologies is built around software quality engineering. Their SDET specialization means they can build, maintain, and scale automated test frameworks rather than just executing manual test cases -- a meaningful distinction for development teams practicing CI/CD who need test automation that keeps pace with deployment velocity.

With US headquarters in Walled Lake, MI and development centers in Noida and Bengaluru, SDET Technologies offers a blended delivery model. US-based account management handles communication, requirements, and time zone alignment while Indian teams provide cost-effective execution capacity. This structure works well for North American companies that need QA scale without managing offshore operations directly.

Genx's blockchain specialization -- spanning smart contracts, secure transactions, and decentralized systems -- differentiates them from typical testing/DevOps firms. For companies exploring blockchain applications in supply chain, finance, or data integrity, this built-in expertise removes the need to onboard a separate blockchain specialist.

With testing and DevOps each representing 35% of their focus, Genx can build and maintain CI/CD pipelines with integrated quality gates -- a more cohesive approach than hiring separate testing and DevOps vendors. This integration reduces the friction of coordinating release management across multiple providers.
