Rheal Software

If you have outsourced before, you may have had challenges with communication, lack of common sense, scope creep, late & incomplete delivery and being over budget. 𝐖𝐞 𝐆𝐞𝐭 𝐘𝐨𝐮! We completely get it and know outsourcing COLD. We have been providing custom software development services for 𝟐𝟑 𝒚𝒆𝒂𝒓𝒔 and we know your pain. I personally resonate with the above points as much as you do and removing these pain points is the fundamental foundation, I have built Rheal Software on. 𝐖𝐞 𝐒𝐩𝐞𝐚𝐤 𝐘𝐨𝐮𝐫 𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞! Before I started Rheal, I was fortunate to study at Penn and later work on Wall Street at Morgan Stanley and Bankers Trust. There I learned about the US work culture, and about what US clients want. I have used this knowledge to build Rheal, where we focus on Great Communication, being Highly Responsive to client needs, and completing projects On Time and On Budget. 𝐖𝐞 𝐚𝐫𝐞 𝐏𝐫𝐨𝐮𝐝 𝐭𝐨 𝐛𝐞 𝐓𝐫𝐮𝐬𝐭𝐞𝐝! That’s why clients appreciate us and that is the reason why they stay with us. But don’t take my word for it! Hear what our clients have to say about us. https://youtu.be/l6QusCoR6nE 𝟗𝟑% 𝐨𝐟 𝐨𝐮𝐫 𝐧𝐞𝐰 𝐜𝐥𝐢𝐞𝐧𝐭𝐬 𝐚𝐫𝐞 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐑𝐞𝐟𝐞𝐫𝐫𝐚𝐥𝐬! We are also proud that 40% of our current clients continue to work with us on multiple projects and have been with us for over 10 years, some of them even longer for over 15. Our focus on customer satisfaction has enabled us to serve over 𝟒𝟎𝟎 𝒄𝒍𝒊𝒆𝒏𝒕𝒔 𝒘𝒐𝒓𝒍𝒅𝒘𝒊𝒅𝒆 across many industries such as healthcare, insurance, construction, real estate, logistics, financial services, transportation, public safety and manufacturing. But this wouldn’t have been possible had it not been for biggest asset … Our Employees. 𝐖𝐞 𝐈𝐧𝐜𝐫𝐞𝐚𝐬𝐞 𝐂𝐥𝐢𝐞𝐧𝐭 𝐒𝐚𝐭𝐢𝐬𝐟𝐚𝐜𝐭𝐢𝐨𝐧 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐄𝐦𝐩𝐥𝐨𝐲𝐞𝐞 𝐋𝐨𝐧𝐠𝐞𝐯𝐢𝐭𝐲! We believe that long-term employees are key to success, leading to better communication and higher client satisfaction. We're proud that 42 employees have been with us for over 10 years, and our management team for over 20. This I believe is the real reason why we have been able to achieve the client satisfaction we aim for. 𝐘𝐨𝐮 𝐡𝐚𝐯𝐞 𝐧𝐨𝐭𝐡𝐢𝐧𝐠 𝐭𝐨 𝐥𝐨𝐬𝐞 𝐚𝐧𝐝 𝐞𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 𝐭𝐨 𝐠𝐚𝐢𝐧 𝐢𝐧 𝐚𝐬𝐤𝐢𝐧𝐠 𝐮𝐬 𝐟𝐨𝐫 𝐚 𝐩𝐫𝐨𝐩𝐨𝐬𝐚𝐥 𝐟𝐨𝐫 𝐲𝐨𝐮𝐫 𝐫𝐞𝐪𝐮𝐢𝐫𝐞𝐦𝐞𝐧𝐭 as we have - No Advance - No Minimum Engagement period - Payment based on Milestones 𝐆𝐞𝐭 𝐢𝐧 𝐭𝐨𝐮𝐜𝐡 𝐰𝐢𝐭𝐡 𝐮𝐬 𝐭𝐨𝐝𝐚𝐲!
