What their customers say

Quotes from people at SIG's customers.

“The SIG analysis helped us regain control. SIG’s recommendations enabled us to minimize the fallout, which resulted in termination of the contract staff hired to manually x the issues. That allowed us to reallocate our resources back to align with our strategic objectives. Great work by SIG!”

Rob Martens · Program Manager · Stedin

““With this certification through SIG and TÜViT, we’ve now got something we can easily show to our future and existing customers to give them confidence that our body language recognition software isn’t just the world’s first – but also has rock solid technical quality.””

Harro Stokman · Founder & CEO · Kepler Vision Technologies

““We have been very impressed by the expertise that SIG has brought to the table and the way they translate their research and findings in clear, concise and simple to understand set of business recommendations. Would we use SIG again for any other digital acquisition? Absolutely!””

Harry van der Vossen · Director of Digital Delivery · RelyOn Nutec

“The former legacy system was nearly 30 years old and had just a two-star rating. Maintenance was therefore becoming expensive and complex. The new system was built from scratch and already has the four-star rating, thanks in large part to SIG. This means maintenance can be executed significantly faster, any errors are much more easily detected and solved, and functional adjustments are executed faster and more efficiently. Therefore, we can maintain IVS Next future-proof with lower costs and risks.”

Peter den Held · Director of Development Services · Rijkswaterstaat

““It is a huge benefit that the installation, including the software, can be managed mainly within one environment. If for instance the configuration of the belt conveyor needs to be adjusted, then you can easily regenerate the code.””

““With the help of SIG we brought the software quality to the next level which helps us to deliver our installations faster.””

R&D Project Manager · MHS

“First our developers were skeptical about SIG. They were afraid of meddling and undermining their autonomy, but after several sessions they felt helped and became more interested. They experienced their software became better. The adversarial sessions were very important in this. Now they are actively pursuing software quality.”

Nico van Didden · Project Manager · ProRail

““We recommend that you continue to monitor the quality of the software on an ongoing basis, even in the post-merger integration process, to ensure you’re integrated into their processes and to ensure that they will have a well structured and well maintainable code base.””

Giles Shrimpton · Managing Director Automotive · Eurowag

““Being ahead of the curve on secure development was important to us. SIG helped us embed security into our daily work long before it became a regulatory requirement.””

Interamerican

““We needed a  digital  platform  that  wouldn’t  just replace our legacy landscape — it had to support the next decade of growth. SIG helped us set the right foundation from day one.””

Interamerican

““ It’s  more visible what  you’re  talking about — more direct, not a fussy discussion. We can see  what’s  going wrong,  what’s  going  good , and what needs more attention. ””

Hans Schreuder · Managing Director of the Board · SBIR

““We needed an independent partner to help us measure the systems. They can tell us that everything is perfectly fine, but we  needed  to know for sure. With Sigrid®,  we’re  getting more guarantees that the software  that’s being delivered is up to par.””

Joel Sanches · Board Member · SBIR

“Power to the customer! Combining various products in a self-service portal is a huge ask from our customers. We continue to mold the value proposition and shape our offerings to improve their user experience.”

Borges · VodafoneZiggo

“The ideal set-up to deliver VodafoneZiggo’s in-house software development capability, ensuring the highest industry standards in terms of quality and working in partnership with best-of-breed suppliers.”

Joao Borges · VodafoneZiggo

“Balancing the equation of greatest value for our customer, fastest time to market, and quality of the software product, we determined that in-house software development would be the most sensible option for us due to the complexity and level of integration of our Flex value proposition.”

Joao Borges · Program Lead · VodafoneZiggo

““As an organization that handles sensitive client data, we want to ensure the highest levels of software quality and security. Embedding continuous insight into our processes gives us confidence that our systems will scale safely and sustainably.””

Cristian Ciuperca · VP Engineering · HeadFirst Group

““Having a real-time view of our software portfolio allows us to build our roadmap on current data and ensure every decision is grounded in fact.””

Cristian Ciuperca · VP Engineering · HeadFirst Group

““We wanted to stay ahead of complexity. As our digital landscape expanded, continuous insight became key to stay in control and ensure we’re always ready for what comes next.””

Cristian Ciuperca · VP Engineering · HeadFirst Group

“SIG delivered a high-quality report analysis in which you really see that this is the core expertise of SIG. Within a strict time schedule interviews and code analyses were done. Based on facts and their extended knowledge of software quality they advised three clear topics for further improvement.”

Hidde Andriessen · CIO Office · KPN

“The lessons that we learn here enable us to make improvements with every upgrade.”

Alex Huisman · Dunea

““That underpinned quite well that having attention for technical debt—or even functional refactoring—you can benefit even while running toward the finish line.””

Harald Thoonen · Solution Architect · Rabobank

““When we pushed for it and embarked on the journey, SIG’s tooling picked up those kinds of languages quickly… It helped us keep control of technical debt and identify where we needed to focus.””

Harald Thoonen · Solution Architect · Rabobank

“”SIG led a cultural change within Vhi, resulting in even more awareness that software quality matters. Our developers can now easily access up-to-date quality ratings of their work via our intranet on a daily basis.””

Vhi

““Based on our successful collaboration with SIG, we upgraded our monitoring service to the Sigrid platform to enhance the software assurance we need for our growth ambitions.””

Louwke van der Steen · CTO · CCS

“The implementation of the new Donor Register has led to a modern and flexible application with the ability to implement changes quickly. This gives CIBG the opportunity to quickly and adequately respond to changing requests and requirements for the register.”

Richard Maat · Head of Delivery · CIBG

“We chose Sigrid to validate the strength of our code base, ensuring our foundations are as robust as we believe. This allowed us to focus our investments on targeted improvements and bolster our security, turning insight into action for a safer, stronger product.”

Gijs Zijderveld · Head of Technology · Intergamma

““The QSD training didn’t only equip our software engineers with capabilities for writing quality code, but also enhanced their awareness about the importance of non functional requirements.””

Ariadi Nugroho · Head of IT Strategy and Planning · BTPN

““SIG’s analysis of the Jenius rebuild scenario shows that improved code quality will reduce our maintenance cost by an estimated 78% and decrease the time needed to make changes by a factor of 3.””

Karim Siregar · CIO · BTPN

““We knew we needed an independent, unbiased opinion from the industry experts on software quality. That’s the reason we turned to SIG.””

Director

“From the start, we really focused on standards, object orientation, automatic controls and mutual QA. With time pressure, it is sometimes difficult to keep up with this. I am therefore very pleased with the result. We have gained very good insights from the SIG analysis. Several improvements have already been implemented, and some are still on the backlog to be picked up. As a result, the team is even more motivated to perform even better.”

Robert Schrijnemakers · Solution Architect and Lead Developer · APG
