Peiko Reviews & Testimonials

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.

Working with A1QA has been exceptional since the very beginning. Their professionalism, efficiency, and quality of work often exceed what we’ve seen from much larger providers.

eCommerce Development Review from Jeremy DELREY
We decided to create an Online shop for selling medicines. So we started with negotiations of the concept and the collection of the requirements. Then team provided us with the technical description of the store and a few mockups of it. After approving everything they start creating a solution.I think that we're about 10-12 people in the team who worked with us. We launched shop and receiving profit from it, I think that's the best outcome.

Working with Kat, Stef, and the whole team at Red Eagle Tech has been a brilliant experience from start to finish. They’ve supported us across multiple digital projects, and every time they’ve delivered solutions that genuinely make our business more efficient while also saving us money.Whenever we bring them a new idea, they approach it with total openness, fresh thinking, and a real understanding of what we’re trying to achieve. They grasp the assignment straight away and always offer smart suggestions that strengthen the final result.Everything with them is transparent, communication, process, and especially pricing. You can tell they know exactly what they’re doing, and their expertise shows in how smoothly each project runs. On top of that, they’re incredibly easy to work with, which makes the whole experience even better.

Frequently Asked Questions
What are the core specializations of IT services companies in the United Kingdom?
IT services companies in the United Kingdom offer a full suite of digital transformation and operational support services, focused on accelerating business growth, ensuring regulatory compliance, and strengthening security. In addition to core functions like managed IT, cloud hosting, and help desk support, key specializations include:Â
- IT consultingÂ
- Digital strategyÂ
- Managed security services (MSS)Â
- Cloud servicesÂ
- Network infrastructure and unified communicationsÂ
- Data backup and recoveryÂ
- System modernizationÂ
What certifications should an IT support company have?
For IT support companies, certifications signal adherence to global and local best practices. ISO/IEC 27001 is essential, crucial for complying with the UK's high data protection standards, including GDPR. Staff-level certifications like ITIL Foundation are also important, as well as Cyber Essentials for cybersecurity. Â
For assessing technical proficiency, look for vendor accreditations like Microsoft Gold Partner or high-level certifications like CISSP (Certified Information Systems Security Professional) for senior staff.Â
What information do I need to provide to an IT services company?
To initiate a successful partnership with an IT services company, you must be prepared to share detailed information across three critical tiers. Initially, outline your business context: including key growth objectives, the total count of users and endpoints, budget constraints, and a clear list of current IT challenges or 'pain points.'Â
Secondly, you’ll need to supply technical documentation, i.e., a complete inventory of hardware, existing licensed software and their keys, a network topology map, and details on any critical legacy systems. Lastly, you'll need to provide a statement of all mandatory compliance requirements and the necessary access credentials for core systems, such as firewalls, cloud tenants, and primary servers.Â
What factors affect IT services agency pricing?
Pricing for IT services in the UK is heavily influenced by the scope and inherent complexity of the required support, which determines the necessary staffing and skillset. Factors that directly impact costs include: the size and scale of the organization (number of users and managed devices), the stringency of the Service Level Agreement (SLA) required, especially for 24/7 or mission-critical support, and the technical maturity of the existing IT estate.Â
Additionally, stringent regulatory compliance will increase pricing, as well as the agency's location within the UK (London-based services typically cost more due to higher labor rates).Â
What questions should I ask United Kingdom IT support company before hiring?
Before committing to a United Kingdom IT support company, pose these questions to thoroughly assess its suitability, expertise, and operational alignment with your business:Â
- What are your guaranteed response and resolution times as per your Service Level Agreement (SLA)?Â
- How do you ensure full compliance with GDPR and other UK-specific data protection legislation?Â
- Do you operate a 24/7/365 UK-based service desk or is support outsourced after hours?Â
- What is your defined process for handling a high-priority cyber-security incident or major outage?Â
- Can you provide an example of how you've helped a client leverage cloud technology for a business outcome?Â
- How frequently do you conduct proactive security testing, patching, and hardware life-cycle reviews?Â
