5(4 reviews)Long-Term Technology Partner for Growth-Stage and Mid-Market Companies
RecommendedFounded in 2013, Mind Studios is a custom software development company working with growth-stage and mid-market businesses across the US, UK, Europe, and MENA. The portfolio spans logistics platforms, real estate marketplaces, healthcare systems, and fitness ecosystems - operationally critical products built for companies where technology is central to how the business runs. The team engages at the architecture stage, before the critical decisions get locked in. Business analysis, technical scoping, and honest pushback on briefs that won't hold up at scale are standard. The goal from day one is a system that doesn't need to be rebuilt in two years. What distinguishes Mind Studios is what happens after launch. Scaling infrastructure, iterating on features, extending systems as the business grows - this is where most of the value gets built, and where long-term client relationships form. The average engagement runs over two and a half years. Many go considerably longer. 100+ specialists. 13 years in business. 70% client retention rate.5 works in Web ApplicationLocated in Dnepropetrovsk, Ukraine (+3)From €20,000 for Web ApplicationWorked in Logistics & Supply Chain (+5)Speaks English, Ukrainian51-200 membersFuturByte

5(7 reviews)Scalable systems for complex business operations — delivered with clarity and predictability.
We help growing and established companies turn complex software initiatives into clear, scalable, and well‑managed systems. Our job is more than just software design and development — our job is taking care of your success. We don't jump straight into development. We start with discovery, solution design, and business analysis to define scope, architecture, integrations, and priorities before a single line of code is written. This is how we reduce delivery risk and protect your budget. We focus on three solution domains: 1. Custom Business Systems & Operational Platforms 2. Mobile Products for Customers and Operations 3. AI‑Enabled Business Workflows (AI under senior engineering control) Our strongest industry experience is in Food & Beverage, Real Estate, and FinTech — with growing expertise in iGaming, EdTech, and Travel Tech. Why companies choose us: clarity before development, structured delivery with PM and QA, domain‑aware solutions, and AI‑accelerated senior engineering. We work best with growing mid‑market companies, multi‑location businesses, and organisations that have outgrown spreadsheets or disconnected tools. We work as an extension of your business, in tight communication and total transparency — so there's no waste of time on back‑and‑forth. Start with a Solution Discovery call – to clarify scope, architecture, and the right path before any build commitment.31 works in Web ApplicationLocated in Tuckahoe, United States (+3)From €10,000 for Web ApplicationWorked in Education (+23)Speaks English, German(+2)51-200 membersTepia

5(3 reviews)Founder-led staff augmentation of AI-Ready Senior Developers and Dedicated Teams in 60 hours
UASOFTDEV is a founder-led staff augmentation of AI-Ready Dedicated Teams and Senior Software Engineers for small-mid companies. We believe AI doesn't replace experienced engineers. It makes the right engineers dramatically more effective. That's why every developer we provide uses AI as part of their daily workflow with tools like Claude, Cursor and GitHub Copilot, while all architecture, technical decisions, code reviews and production releases remain under experienced human ownership. Main engagement models. Staff Augmentation for companies looking to extend their existing engineering team with senior talent, and AI-Ready Dedicated Teams for businesses that need a complete delivery team with technical leadership capable of owning products, features or entire engineering initiatives. Every engagement is led directly by our Founders. Aleksey, CEO, works closely with clients to understand product goals, business priorities and team dynamics. Oleksandr, CTO, personally evaluates every engineer for technical excellence, communication and problem-solving skills. Our work is built around four core values: quality, clarity, transparency and a personalized approach to every client engagement. The process is simple: after a discovery call, we match engineers to your technology stack, product domain and culture, present a CTO-vetted shortlist and run contracting alongside onboarding. Staffing typically happens within 60 hours. Today, our teams support startups and product companies across Europe, UK and North America. UASOFTDEV's track record includes a 97% first-candidate acceptance rate, a 95.65% first-match success rate and an average client engagement of over 13 months.
