Space-O Technologies vs Existek: overview
Space-O Technologies
Space-O Technologies was founded in 2010 by Rakeshkumar Patel and Atit Tusharbhai Purani, growing to roughly 140 full-stack engineers and AI specialists with offices in the US, Canada, and India. The company built its reputation on mobile app development (including early on-demand apps and EdTech products) before extending into machine learning on both neural and non-neural networks, working with frameworks including Keras, Caffe, and TensorFlow, plus more recent integration of OpenAI's GPT, Whisper, and LangChain. Its origin as a mobile-app shop means ML is a newer, added capability rather than the company's founding focus.
Existek
Existek was founded in 2012 and operates with a 50–249 person team split across Bucharest, Romania and Vinnytsia, Ukraine, delivering custom software development, dedicated team staffing, and AI development services for clients in business intelligence, healthcare, oil & gas, and education. The company has been recognized by Clutch as a top developer in both Ukraine and Romania and holds a near-perfect 4.9 rating on the platform, with hourly rates of $50–$99/hr and a minimum project size of $25,000+. Its AI services page is comparatively general, offering less publicly documented technical specificity than boutique ML specialists in this list.
