worked with Lazarev Agency on a SaaS platform for AI tools, and it was a great experience. the team was responsive, understood our needs, and delivered clean, user-friendly designs. They made the whole process smooth and straightforward
Valeria Semenova's Review Sourced from Google
When we first met, I knew Lazarev would be the right company to build the online version of our boutique design studio. Their attention to detail, while hand crafting an UI that resonates the brand well has been commendable. They designed something that really represents our aesthetic, while also providing a very seamless and beautiful shopping experience for our customers. The backend, meanwhile, is equipped with AI-enabled analytics to keep track of our customers' behaviors and help us to manage our stock levels. Lazarev's team proved to be respectful, careful and imaginative throughout the project, not just a service provider, but a real partner. Since launch, both our traffic and sales numbers have significantly increased, evidence of their hard work and expertise.

RGray Reviews & Testimonials

Startup Review from Helen Guzenko
Wezom is an enterprise software development company with more than 275 specialists. We brought RGray in for startup marketing and growth marketing for a FinTech SaaS platform we had built for a client, an early stage startup with a finished product and almost no market presence. RGray started with their startup marketing foundation: market and competitor research, positioning and messaging, and a growth strategy built on three prioritized hypotheses, each with its own funnel and success metrics. They then implemented the channels: SEO, GEO for visibility inside AI search and AI assistants, PR and digital media, and paid user acquisition to test the funnels fast. Analytics and attribution were in place from the start.They also built AI into the daily marketing work: a custom multi agent system using Claude, Grok, Perplexity and Gemini for research, content production and localization, handed over with workflows, prompts and checklists. Two of the three hypotheses proved out, so we elaborated those two and their funnels. CAC started at $31 and fell to $16 by the end of the test campaign, below the industry average. The campaign brought around 2,500 activated users, which boosted revenue and gave us real data for funnel, user and product analysis. The client finished with a working acquisition system and the documentation to run it, not a set of campaigns. Project management was on time and on budget: weekly calls, a shared board with owners and deadlines, monthly reporting against the strategy metrics, same day answers. When our client's roadmap moved, they resequenced the plan in days. Most impressive: they think like product owners, not like a service agency, and they challenged our ICP and pricing assumptions correctly. One improvement: the early reports were denser than we needed, and they added an executive summary once we asked.
Helen Guzenko's Review Sourced from Google
RGray is a fantastic team to work with. They really understand their clients’ customers and always come up with creative, effective solutions. Thanks to their work, we improved our SEO rankings, attracted new users, and achieved 2x growth. Highly recommend them!

Software Development Review from Slava Berkovich
SapientPro consistently delivers high-quality work that aligns with project requirements. The team demonstrates strong expertise in Angular, TypeScript, and JavaScript. Their project management and communication practices are highly effective, with weekly client meetings held to provide updates on progress and ensure alignment.

Software Development Review from Jeremy Ott
This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

eCommerce Development Review from Luc Vlekken
We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.
