Staff Augmentation Review from Mitya Smusin
Solveit managed our comprehensive eCommerce project, developing a full-featured web platform with Node.js and React technologies. The agency also created a Flutter-based mobile app for seamless data synchronization across iOS and Android devices. We were thoroughly pleased with Solveit's expertise and adherence to deadlines. It provided timely updates and communicated openly about our project's status. Solveit's proactive approach and transparency were exceptional, particularly during the staff augmentation process, where the agency efficiently matched us with qualified candidates and facilitated a smooth onboarding. We were satisfied with Solveit's high-quality work and exceptional support.

Design Services Review from Anna Harissis
They have an incredibly hardworking team at affordable pricing. SolveIt has built the app earlier than expected, and they continue to complete new tasks within the client's budget and timeline.

iPhone Review from Gabriel Sabadin
We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

We've partnered with Sigma Software for almost three years, and they proved to be a strong partner with whom we'll keep working. Their adaptability and willingness to get things done are unique, settingthem apart from other providers. Moreover, they demonstrate a strong sense of ownership.

Software Development Review from Michael Meyer
We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Mobile App Development Review from Esther Howard
The client is incredibly happy with Sigma's services and work. It has referred 3 other clients who also say how much they really love the team and process to get set up with the agency.

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!

Appingine Reviews & Testimonials
David Dorough's Review Sourced from Google
I read reviews of almost 100 companies and spoke with reps from 5 before finally going with Appingine for my first app. I'm sure you can pay more for less quality from a different company but why would you? They were easy to work with and quick to respond to questions. They split the charges by stage of development like every professional company should.I needed to make several changes during development and the cost was reasonable. Anthony was awesome and helped me along every step of the way. Apple has more stringent requirements than Google and Appingine was able to get the app published on both stores. Looking forward to more projects with them. Once again, don't pay more for less, go with Appingine!
