Web Development Review from Mathias Willburger
The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.
suresh's Review Sourced from Google
Candidates should carefully evaluate whether to participate in this interview process. Based on my experience, it seems the interviews are being conducted primarily for showcase purposes rather than actual hiring, leading to a significant waste of candidates' time, preparation, and effort.
Deekshu Gunaga's Review Sourced from Google
Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience

Odoo Review from Navrina Singh
As a growing business in Australia, our internal systems had become difficult to manage. We partnered with SDLC CORP for Odoo development, and their team took the time to understand our workflows and bottlenecks. They automated repeated tasks, streamlined our processes, and kept communication clear at every step. This was not a one-time quick fix; it continues to improve how we run the business every day.

Working with SDLC Corp on IoT supply chain project has helped us at Freight Right Global Logistics. Their smart tracking and fleet management have helped us work faster by reducing delays and improving delivery routes. The temperature sensors for perishables gave us peace of mind, keeping our products safe and fresh. Overall, their expertise and smooth support made the whole process easy and stress-free!

Mobile App Development Review from Jacine Greenwood
They've delivered a completely new experience with our main products: loans, credit cards, payments, and accounts. a new customer onboarding procedure. We only published the app a week ago, and as of right now, there hasn't been any noticeable influence on NPS. But I have no doubt that it will be.

Web Development Review from Cesar Velasquez
Project is very close to launch. My entire staff/team are greatly impressed by the results thus far and we are very confident that we will launch with a very impressive-looking site with full functionality. I feel the product we take to market will greatly enhance our overall image and much of our success will be because of the product we have to offer.

Web Development Review from Marlon Bensching
Vitec GMBH did a phenomenal job in setting up a great sustainable software architecture. It is very important to me that a lot of our customers and mostly partners can use our marketplace and have a great experience while using it.We as a well known company in area Stuttgart and Frankfurt in Germany cant risk it to ship a faulty product that would breake by to many users. This was our biggest concern and Vitec didnt let us down.

Marc and his team are the best in the business! Diligent, hardworking, professional, and excellent communicators. Not to mention, their work is high quality. I recommend Vitec GmbH to anyone looking for software development services. They will make your dreams come true.

Strategy Consulting Review from Dragomir Zarev
Bringing Georgi Tonchev into our UK expansion planning was one of the most strategic decisions we made. His structured approach to go-to-market strategy helped us move beyond surface-level market entry and deeply understand how to position Roadgames as a unique outdoor team-building provider in a mature and competitive UK events landscape.Georgi guided me in refining our ideal customer profilesfrom HR leaders to corporate event plannersand aligning our messaging with their pain points and decision criteria. He played a key role in identifying underserved segments looking for sustainability-driven, authentic outdoor experiences, helping us differentiate against indoor-focused incumbents.Through his Strategic Reset Framework, we created a repeatable customer acquisition model, clarified our value proposition for each partner tier, and defined a content-led LinkedIn outreach strategy that speaks directly to decision-makers. The outcome is a UK market entry strategy that is both creatively bold and commercially grounded. We now have a clear path to scalable growth, measurable outcomes, and a sharper ESG-aligned brand presence in the UK.
