Roshan CEO at NanoTherapX5.0★Web Design Review from Roshan
This is Roshan, CEO at NanoTherapX. Working with Probey Services for our CRM Development. What stood out most was their stability, consistency, reliability, and a smooth implementation. The CRM has streamlined our client management, improved team efficiency, and helped us manage operations more effectively. Since its implementation, we've seen better productivity and consistent business growth. I highly recommend Probey Services UK to any business looking for a reliable technology partner.
Tejaswini Director at Green Matter Packaging5.0★Mobile App Development Review from Tejaswini
What stands out most about Probey Services is their discipline-no missed calls, no vague timelines, and no surprises. They built our mobile app with a level of professionalism that made us feel like a priority throughout the project. The delivery was on schedule, the code quality was excellent, and the final product met high standards. Since the app launch, we've seen consistent business growth, and managing customer orders has become much more efficient. I highly recommend Probey Services UK to any business looking for a dependable technology partner.
Varun Shivhare Founder at Sunran Alcobev5.0★Web Development Review from Varun Shivhare
Working with Probey Services UK on our website design and development was a valuable business decision. Their team maintained Functionality, Modernization, and translated our brand vision into a modern, business-focused website. The new website has strengthened our digital presence and generated positive business engagement. We are equally satisfied with their after-sales support, as minor technical bug fixes, content updates, and ongoing assistance have always been handled promptly and professionally.

Bilberrry Reviews & Testimonials
Kelly Johnson eCommerce Specialist at Rapala VMC5.0★eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.
Adam Ely, PMP Director of Operations at Sands Investment Group5.0★Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation. The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.
Ari Bixhorn VP, Marketing at Outpost5.0★Web Design Review from Ari Bixhorn
Bilberrry’s work gave our new website improved performance, greater SEO flexibility, and pages that are much easier to build. They delivered everything on time and kept communication proactive throughout. Their strong project management, technical expertise, and responsiveness built real trust during the process.

Chop Dawg Reviews & Testimonials
Charlie Alexander CEO at Crow5.0★Mobile App Development Review from Charlie Alexander
I needed a strong prototype for a luxury fashion and social media app that could help secure investor funding before moving into full development. The idea was to let users post high-end products inside the platform, while giving their friends access to discounts when they clicked through. I brought Chop Dawg a rough template of the concept, and they turned it into a detailed InVision prototype with clear navigation and a polished flow. Their designer did an excellent job, and the team offered helpful product insight from the start. The process gave me a clearer understanding of the app’s direction, and I plan to continue with them for development.
Jordan Habben Co-Founder at Misfit Innovations5.0★Mobile App Development Review from Jordan Habben
Chop Dawg developed our first mobile app from scratch for iOS and Android, guiding us through each step of the process. Their strong recommendations, transparent pricing, and Joshua’s accommodating approach made them stand out during our search. The team delivered everything promised, produced outstanding work, and helped shape an app design that felt thoughtful and custom rather than generic.
Anonymous Founder at Vault Personal Storage5.0★Web Design Review from Anonymous
Chop Dawg designed the website, logo, quote feature, and web app prototype for Vault Personal Storage. As an early-stage startup, we needed a team that understood our vision and could create something strong enough to show investors. They exceeded expectations, stayed professional and flexible, and delivered far more value than larger firms we considered.

- Challenge: A private hospital was overwhelmed with administrative tasks, billing complexities, and manual data entry, leading to longer waiting times and growing frustration among patients. Seeking to mitigate the dissatisfaction, it tasked Jelvix to develop a chatbot that could assist with patient queries and administrative work efficiency.Â
- Solution: Jelvix developed the solution in two phases, with the first one focusing on training the chatbot to understand written and vocal patient inquiries, ask follow-up questions regarding their symptoms and medical records, and direct them to the appropriate department and specialist. For the second phase, Jelvix implemented dashboards, an admin, a user portal, and functionalities for sending automated appointment reminders.Â
- Results: The AI chatbot managed over 3,000 messages daily, thus tripling patient response inquiries and elevating patient satisfaction. It also improved hospital productivity, enabling the entity to focus more on patient care.Â

How many software development companies are in Seattle?
Washington ranks as the state with the highest concentration of software jobs across the United States. Namely, there are approximately 76,000 developers in the Seattle-Tacoma-Bellevue area, indicating a lucrative ecosystem in the region.Â
Of the 7,500 software development companies listed on DesignRush, 45 are based in Seattle. Here’s a breakdown of the data by company size: Â
| Company size | Percentage of agencies |

Mid-sized (50-249 employees)Â | 33%Â |
Large (250+ employees)Â | 11.5%Â |
Enterprise (1000+ employees)Â | 6.5%Â |
With 72% of listed software development companies in Seattle falling under the small and medium-sized brackets, it can be deduced that there’s a prevailing demand for boutique firms in the area. This trend is likely driven by the city’s thriving startup ecosystem, where emerging companies predominantly seek cost-effective service from smaller development agencies to develop minimum viable products (MVPs) and scale them into robust software offerings.Â
On the other hand, the smaller percentage of large software development companies in Seattle may reflect a focus on specialized projects rather than high-volume development. Additionally, many businesses requiring large-scale development usually choose to outsource projects to regions with lower operating costs to maximize their allocated project budgets.Â
