Marc Casper Chairman, President and CEO at Thermo Fisher Scientific
5.0★
Digital Advertising Review from Marc Casper
For the digital marketing portion of the project, Scan tracked growth and engagement on our social media platforms. It was clear that their work directly drove growth in our online presence. On the web development side, our investors and internal executive stakeholders were impressed with their work. Its too early to truly gauge the value of the site, but in the immediate term, those who didn't like the old site have really liked the new one.They were great with structuring regular Zoom calls to keep everything on track. Outside of these calls, we communicated via email and Basecamp.

Digital Advertising Review from Amanda Watts
In our email marketing campaigns, we've seen a 25% return on investment. Our PPC ROI is 250%. They've found a way to attract an audience to our site despite safety training not being an objectively exciting subject.Their project management skills are fantastic. They report progress to us multiple times a day, which keeps me happy. Scandiweb is always in touch with us to make sure we know how everything is going. We never have to chase them down about anything.

eCommerce Development Review from JOSHUA MARGOLIS
The purpose of this project is to redesign the existing website with a modern, user-friendly interface and integrate a custom checkout system tailored for subscription-based services. The new design will enhance the user experience, improve site performance, and streamline the subscription process to increase conversions and customer retention.The speed at which you completed the project without compromising on quality is truly impressive. Not only did you meet our tight deadlines, but the site also looks modern, runs smoothly, and the functionality has been greatly improved.Your attention to detail, responsiveness, and ability to quickly address any feedback or issues along the way made the whole process seamless. This upgrade has already made a significant difference, and we couldn't be happier with the results.

Peter Mukherjee's Review Sourced from Google
I first met with Matt and his team over a year ago when planning a new website to support a business project. I had been recommended to Lightflows by someone who employed them for a very complex site and was very impressed with what they had done, se decided to engage them too. Right from the beginning I found their professional approach outstanding, and they managed to design and build a site for me with continuous feedback throughout the whole process. There are many web designers out there but it can be very difficult to find someone really good. After my complete experience with Lightflows, I would have absolutely no hesitation in recommending them to anyone - especially those that want a bespoke design that portrays their business perfectly.

Matt and his team re-designed the front-end appearance of our asp.net website (123 Sheets) for users who have logged in. We were amazed with the final result, I personally think we would have struggled to find the same beauty anywhere else for a similar price - a big thank you to the whole team that worked with us to achieve this!

Stopped in for some Magic card boosters and was greeted warmly by all staff and the owner, who gave me a rundown of upcoming gaming events at the store. I was blown away by the complex schedule they keep - free play, draft play events, and more. The owner gives freely of his time to provide those events, and it's clear he cares.
Perry Review from Google

Perry's Review Sourced from Google
Extremely judgemental, sad, employees. I recently moved to town and came in after work in my business attire. After getting a confused look from the associate up front, (not even a greeting). I started browsing, but everytime I looked up, I was being stared at which made me slightly uncomfortable. I moved towards the back and an associate there said hello, we had a short chat about comics and trading cards but they were rude to a younger customer that came in, it was unwarranted and I'm assuming either this is the employee's normal behavior or an elitist owner. I also couldn't help but wonder if the associate was under some sort of influence. After noticing the trading card prices are exponentially higher than I'm used to seeing in bigger cities, where that sort of pricing would make more sense; I took my leave not purchasing anything feeling underwhelmed. As I passed the associate up front, they still did nothing but continue to stare. Are they not used to the professional community? The store is tidy and organized but cluttered and the atmosphere/vibe is cold. Also not much of a variety for a hobby store. I would much rather take the trip to Milton Freewater to the hobby store there or even Gamestop would be a better choice. I do not see myself returning in the future.

What are the core specializations of custom software development companies in the United Kingdom?
The core specializations of custom software development companies in the United Kingdom generally center around web/mobile app development and advanced digital technologies. Their expertise extends to AI-powered products, cloud solutions (especially DevOps), feature enrichment, and cybersecurity.
Overall, they provide end-to-end digital transformation solutions and engineer custom platforms and systems that drive competitive advantage and business growth across industries.
How much do software development services cost in the UK?
The cost for software development services in the UK ranges from £25,000 to £120,000 for small businesses. In contrast, large enterprises undertaking extensive digital transformation or building sophisticated, bespoke systems should anticipate costs starting at £80,000 and potentially exceeding £500,000.
For startups or businesses aiming to validate a concept, the initial cost is considerably lower. A minimum viable product (MVP) or a proof-of-concept generally falls within the £5,000 to £30,000 range. The final price is ultimately determined by the project's complexity, the chosen technology stack, the developers’ experience, and the geographical location of the service provider, which impacts their hourly or daily rates.
How do I choose the right United Kingdom software development firm?
To choose the right United Kingdom software development firm, begin by evaluating its portfolio and case studies to make sure they have experience in your required technology stack and niche. Inquire about its process and team structure, to make sure they follow an iterative methodology and that the core development team will be dedicated and accessible for regular communication.
Finally, prioritize a company with good reviews that reflect a track record of robust post-launch support and good collaboration throughout the project.
Do software development companies provide ongoing support?
Yes, software development companies do provide ongoing support, maintenance, and updates after the product launch. This post-launch service is important for fixing bugs, maintaining security, adapting to changing user needs, and making sure the software remains stable and competitive.
How do custom software development companies in the United Kingdom handle project revisions?
Custom software development companies in the United Kingdom predominantly handle project revisions through the Agile methodology. This involves breaking the project into short, iterative sprints, allowing the client to provide feedback and request necessary revisions at the end of each cycle.
This flow is intended to minimize risk and keep the final product aligned with the envisioned concept, rather than waiting until the end for a major change.
