Peiko Reviews & Testimonials
Sergei Bliznyuk CTO & Co-founder at Kozak Agency
5.0★
Blockchain Review from Sergei Bliznyuk
We've been working with Peiko on a complex blockchain infrastructure project, focused on building a custom Layer-2 scaling solution for our ecosystem. The goal was to reduce network congestion and lower gas fees, and their team has been involved from the initial discovery phase through ongoing development.What stands out most is their ability to turn complex blockchain concepts into practical solutions that align with real business needs. They don't just execute tasks, they actively contribute to shaping the product, helping prioritize features based on long-term goals. Their technical expertise is strong, and theyve delivered solid documentation, a clear backlog, and well-optimized smart contracts.Communication has been smooth overall. At one point, we adjusted the format of updates to get more visibility into the process, and they were quick to adapt and provide more detailed insights without any friction.The project is still ongoing, but the solution is already partially implemented and integrated into our ecosystem. So far, the collaboration has been professional, flexible, and well-managed.

Blockchain Review from Valeriia Subota
Peiko developed a complex stablecoin management platform for us from the ground up. They successfully took over the entire lifecycle, delivering critical technical documentation and UI/UX design where previous teams had struggled.The expertise of their Business Analysis team was exceptionalthey translated our vision into a robust technical architecture with precision. The high-quality MVP they delivered was instrumental in helping us secure VC funding. Throughout the process, the team maintained seamless communication and provided direct access to the developers, ensuring the project was completed exactly on schedule. A highly reliable choice for any high-stakes blockchain or fintech venture.

Blockchain Review from Catherine Ilashchuk
If you're building something technical, you know how easy it is for things to go off the rails. Peiko is the first team Ive worked with that actually got ahead of those issues before they started.Instead of just taking our money and starting to code, they forced us to slow down and nail the architecture and logic first. At the time, I just wanted to move fast, but that planning phase is the only reason we haven't had to rebuild half the platform mid-way through. They caught logic gaps we hadn't even considered.The communication is solid, no fluff, just direct updates on where we stand. They also didn't just build whatever I asked for; they pushed back when they thought a feature would bloat the MVP or mess with our timeline. Having a team that actually thinks about your budget and your launch goals like a partner, rather than just a vendor, makes a massive difference. Were heading into our next round of funding with a product that actually works and documentation that proves it.

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.
