Web Development Review from Mathias Willburger
The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.
suresh's Review Sourced from Google
Candidates should carefully evaluate whether to participate in this interview process. Based on my experience, it seems the interviews are being conducted primarily for showcase purposes rather than actual hiring, leading to a significant waste of candidates' time, preparation, and effort.
Deekshu Gunaga's Review Sourced from Google
Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience

Frequently Asked Questions
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.
