Ben Lord Review from Google

Ben Lord's Review Sourced from Google
I’m not usually one for making posts like this about other companies I do business with but given what I’ve experienced over the last 5 years, I feel very compelled to raising awareness into my experiences with Dotsquares.Initially, this company was very good at handling our website requirements. It was thanks to this that when I became the owner of Lorryspotting.com that I figured it would make sense to have them upgrade that website. It was a big project but with all the accolades and expertise that Dotsquares boasts about, it seemed to be within their scope of capability.Instead, it turned into the most miserable of projects that was riddled with the purest incompetence that I’ve had the misfortune to witness in almost 20 years of business. As per their terms of business, I advanced paid for part of the project yet they were incapable of delivering a functioning website. Added to this, the ageing status of the old site meant we suffered a server failure 16 months ago and when restoring the old site, it was proven that Dotsquares negligently compromised the colossal amount of data held on that site to potential hackers. By this point, enough was enough. Despite so-called “project managers” apparently understanding my business, they became mouthpieces with a catalogue of excuses and rhetoric that failed to take responsibility enveloped by expectations we would continue to pay to fix what they had caused.Ordinarily, escalating this to a company’s CEO should yield an immediate improvement to rectifying a situation. The CEO of this company ignored my email and relegated its handling to the very people causing the problem and failing to deliver any outcomes. It was therefore with no other alternative that I had to commence legal proceedings against this company. Despite repeated attempts to defend what was in essence an indefensible position, we reached a settlement on the matter, the terms of which I’m bound by a confidentiality order but has avoided it being played out before a Judge.Based on my reflections, this company may theoretically claim to value their customers but in reality their actions speak far louder. They do not deserve to be in business and I can’t even begin to fathom how they deal with some of the brands that their client list cites. I would absolutely urge anyone who does, or considers to work with them in any capacity to run for the hills - you will regret it otherwise! I only wish I had of checked out some of the reviews that are out there - reflecting on them now resonates virtually a carbon copy as to my experiences!

Palak Vig's Review Sourced from Google
I have been waiting for my website to be completed for two years now, and the experience has been increasingly frustrating. The lack of timely communication and follow-ups from their side has been disappointing. Despite my repeated efforts to get updates and move things forward, progress has been unreasonably slow. I expected a much higher level of professionalism and responsiveness. I hope they take this feedback seriously and improve their communication and delivery timelines moving forward.

KARTHICK K's Review Sourced from Google
We were exploring ways to automate some of our internal processes and reached out to Rytsense Technologies for AI agent development. What I appreciated most was that they didn't jump straight into the technology. They spent time understanding how our team worked and what challenges we were trying to solve. The AI agent they built has helped us save time and improve efficiency. The entire experience felt collaborative and professional. If you're looking for an AI development company in India that genuinely listens and delivers, I would definitely recommend Rytsense.

We came across Rytsense Technologies while looking for an AI development companies in India and decided to connect with their team. From the first conversation, they were easy to work with and took the time to understand what we were trying to achieve. They explained the technical aspects clearly, provided practical suggestions, and kept communication open throughout the project. The entire process felt well-organized, and we were happy with the outcome. It was a positive experience working with their team.

Arun Kanagaraj's Review Sourced from Google
What stood out about Rytsense Technologies was their ability to understand our business problem before discussing the technology. We initially approached them with a rough idea for an AI agent, and their team helped shape it into a practical solution that our team could actually use. The process was straightforward, communication was clear, and the final result saved us a significant amount of manual effort. If you're looking for an AI Agent Development Company in Chennai that focuses on solving real business challenges rather than just building software, Rytsense is worth considering.

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?

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.
