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.

Branding Review from Dustin Rea

The team at ATOM6 have been absolutely phenomenal partners on multiple client-facing and internal projects. We have done branding, UI / UX, design systems, wireframing, and product design. Gus and his team are experts in the field of design and are able to collaborate with product organizations to bring vision to life. ATOM6 does not cut corners on quality and has an excellent process for getting from idea to final product. I'm looking forward to a long-term partnership with the team.

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!

Helen Guzenko Partnership Manager at Wezom

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.
