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.

Elogic Commerce Reviews & Testimonials
Hanna Dobromyl Technology Partnerships Lead at Akurateco
5.0★
eCommerce Review from Hanna Dobromyl
We brought Elogic in as an extension of our engineering team to help Akurateco scale integrations across Shopify Plus, Adobe Commerce, and custom commerce environments for enterprise merchants. Their senior engineers integrated smoothly into our workflows, covering integration development, platform customization, and technical consulting - with communication that stayed transparent, disciplined, and proactive throughout, from status updates to flagging risks early. Elogic's strength showed most in complex B2B commerce - account structures, merchant-specific configurations, and enterprise buying requirements - and in integrating our stack with ERP, CRM, PIM, and other backend systems. When priorities shifted, they adapted without friction, and for an engagement of this scope, the value was clear: their process lowered hiring risk and let us scale delivery without building that capacity in-house. The impact has been measurable: integration delivery accelerated by roughly 3040%, delivery capacity grew by about 50%, and we've been able to support enterprise merchant requirements faster without expanding headcount. This is an ongoing partnership, and Elogic continues to be a reliable technology partner as we scale.

B2B Review from Anna Korobkyna
Elogic helped us build and improve the digital experience around our enterprise cybersecurity platform, focusing on customer-facing workflows and a more scalable way for enterprise customers to manage their accounts and services. As our enterprise customer base grew, many processes still required manual involvement from our internal teams, which became difficult to scale. We needed a partner who could understand our business processes and help us build a more efficient and maintainable solution. Elogic supported us with customer portal development, account management workflows, API integrations with our existing systems, backend and frontend development, QA, and ongoing technical improvements. What stood out was their ability to understand the complexity of enterprise requirements and think beyond individual tasks. They focused not only on delivering functionality but also on creating solutions that could support future growth. Communication was clear and proactive throughout the engagement. The team adapted well as priorities evolved and worked closely with us to keep everything aligned. The result has been reduced manual effort in customer workflows, a stronger foundation for scaling enterprise operations, and more time for our internal team to focus on advancing our core security platform. This is an ongoing partnership, and I would recommend Elogic to B2B software companies looking for a technology partner to build scalable customer-facing platforms and complex integrations.

eCommerce Development Review from Julia Klotsko
We brought Elogic in to build a Shopify store from scratch for one of our clients - a project that required not just a clean storefront but deep integrations with NetSuite for ERP and Brightpearl for order management, alongside our full marketing stack. That combination of storefront and backend complexity is exactly where a lot of agencies fall short.Elogic handled it without missing a beat. The discovery phase was thorough - they mapped every integration touchpoint before writing a line of code, which eliminated the kind of mid-build misalignments that usually cost real time and money to fix. Both workstreams ran in parallel and came together cleanly at launch.The results were tangible: over 120 pre-orders in the first two weeks, 40% above target; order processing errors dropped by roughly 70% after Brightpearl automation replaced manual handling; inventory discrepancies between the storefront and NetSuite went to zero; and paid media ROAS improved by 25% in the first month simply because attribution was finally accurate.Project management was disciplined and transparent throughout - we always knew where things stood, and when requirements shifted mid-build, the team adapted without friction. After launch they stayed actively involved, optimising performance and flagging issues proactively rather than waiting to be asked.For a project of this complexity, Elogic delivered strong value for money. I would recommend them to any agency or business dealing with backend system complexity alongside a storefront build - that's where they genuinely stand out.

Wayne Barker's Review Sourced from Google
The Summit team are smart, knowledgable and engaging and made the project fun from the first briefing call. Maybe we could've figured out how to build our Mybridity website in-house (we've seen the adverts!) but I'm so glad we didn't go down that path. We made more progress in less time working with Summit and, as a result, have a growing pipeline of projects.

Roger Walker's Review Sourced from Google
When we came up with the idea of a web portal for searching and booking experiences and activities from across the county, it was clear that a quality, bespoke website was going to be crucial to our business model. The team at Summit worked hard to understand the concept of what we were trying to achieve, helped design our logo and corporate identity and then worked tirelessly to build a robust website for us. They continue to support our ongoing development, offering friendly and knowledgeable advice. Summit are well worth contacting to discuss a new website build, or to offer a boost to your current site

What certifications should a United Kingdom website development agency have?
A United Kingdom website development agency should have certifications related to legal compliance and information security to demonstrate professionalism and adherence to best practices.
Key credentials include:
ISO 27001 for information security
ISO 9001 for quality management
Cyber Essentials or Cyber Essentials Plus for UK-specific cybersecurity assurance
It’s also helpful if the team holds platform-specific or developer certifications, such as AWS, Azure, GoogleCloud, Adobe, or recognized frontend/backend development credentials. Membership in professional bodies like BCS (The Chartered Institute for IT) further signals credibility and adherence to industry best practices.
How long does a typical web development project take?
A typical web development project takes 6-12 weeks, depending on the site’s size, features, and design complexity. Simple brochure-style websites may be completed in 3-6 weeks, while more advanced sites with custom functionality or integrations take longer.
Content readiness, feedback speed, and revision cycles also affect the timelines. eCommerce platforms or custom web applications can extend to 3-6 months or more due to testing, optimization, and deployment requirements.
What happens after a website development project finishes?
After a website development project finishes, the agency typically conducts final testing, qualityassurance, and launchsupport to make sure the site works smoothly across all devices and browsers. They also hand over credentials, documentation, and training so your team can manage the site confidently.
Most companies offer ongoingmaintenance, securityupdates, backups, and performancemonitoring to keep the website stable and up to date. You can also choose optional services like content updates, feature enhancements, and SEO support to continue improving your site after launch.
Do web development companies in the United Kingdom offer fixed-price packages?
Yes, many UK web development companies offer fixed-price packages. When you consider a fixed-price package, make sure:
The scope and deliverables are clearly defined upfront
Payment terms, revisions, and any additional costs are transparent
There’s clarity on what happens if the project scope changes or grows
Can web development agencies in the United Kingdom work within tight deadlines?
Yes, many web development agencies in the United Kingdom can work within tight deadlines, especially when dealing with well-defined projects or smaller websites. They often streamline timelines by allocating extra resources, using proven frameworks, and following efficient project management processes.
The ability to meet a fast turnaround depends on project complexity, content readiness, and how quickly you provide feedback. For urgent projects, agencies may offer expedited services at a higher rate to ensure quality isn’t compromised.
