Highly recommendedTop awardedWebsites · Branding · Software Website: https://www.u1core.com/ Book a call: https://calendly.com/hello-u1core/30min Most companies outgrow their digital before they notice. The business is strong, the team is good, the product works. But the website is still the first version, operations still live in spreadsheets, and the brand says nothing a competitor couldn't say. That's where we come in. WHAT WE DO · Websites — marketing sites, landing pages and platforms that sell before your team has to · Branding — identity and design systems that position you at the level you actually operate at · Software — web and mobile products, internal tools and operational systems that replace manual work WHY ONE TEAM Brand agencies do brand. Product studios do product. Outsourcing firms write code. The real problems sit between those disciplines — which is why we do all of it, under one contract, with one person accountable for the result. WHO WE WORK WITH Companies with real revenue and a team in place: founders and owners scaling past their first system, operators rebuilding for growth, and businesses entering a new market. WHERE WE'VE PROVEN IT $720M+ processed through a platform we built. Classified marketplaces with millions of listings. Trading exchanges and auction systems running in production. SaaS, fintech and marketplace products across 40+ projects. HOW WE START With a diagnostic, not a proposal. We look at your website, brand and operations, show where you lose trust, traffic and time — and what to fix first.

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. Founders respond to critical issues within two working hours. Whether you need one senior engineer or an AI-Ready Dedicated Team, our goal is the same: help you ship faster with engineers who communicate clearly, contribute from day one and solve complex problems independently.2 works in Mobile AppLocated in London, United Kingdom (+4)From €10,000 for Mobile AppWorked in Hospitals & Healthcare (+3)Speaks English11-50 membersAscendro Technologies
4.8(15 reviews)Growing with Technology
Highly recommendedTop awardedAbout Ascendro Ascendro is a German-Romanian engineering company that builds and runs software-critical systems. Around 45 senior engineers, working from Timisoara and Germany. Most software vendors treat go-live as the finish line: the system is delivered and operating it becomes someone else's problem. We work the other way around. We take end-to-end responsibility for architecture, delivery and production operations - uptime, incidents, deployments, security - and stay accountable for how the platform behaves for years afterwards. This matters most when software becomes business-critical faster than the infrastructure around it matured. A pilot turns into a production service. The internal team knows the domain but was never sized to run a platform 24/7. That is where we are useful. We do not rebuild operations for every client. Our DevOps Foundation is a reusable, cloud-agnostic backbone for CI/CD, monitoring, logging, authentication and backups, already running across multiple live environments. It moves systems into stable production without a client having to hire a platform team - and we can operate it afterwards. Track record BMW DriveNow - the city-scale shared mobility platform; Ariston and Wolf - connected heating and manufacturing-critical environments; Thinksurance - a regulated, high-availability insurance distribution platform; Samsung - release management for large-scale software delivery; Several of these engagements have run for many years. We are certified to ISO 27001 and TISAX, staff senior squads rather than interchangeable headcount, keep 85-90% engineer retention, and give clients direct founder access instead of account managers.Looking for work in Mobile AppLocated in London, United Kingdom (+2)From €1,000 for Mobile AppWorked in Automotive (+18)Speaks English, French(+2)11-50 membersTOL Inc
5(3 reviews)Software built at the frontier of what's now possible.
RecommendedTake Off Labs is an AI-native software studio. We design, build, host and maintain products end to end, with AI woven through the process rather than bolted on at the end. Fourteen years of shipping, more than a hundred companies, across healthcare, fintech, e-commerce, real estate, logistics and maritime. We also build and run our own products, Doc2Data.io for document AI and Microsites.AI, which means the architecture decisions we recommend are ones we live with ourselves. How we work: prototypes that map real user journeys, AI-augmented build from the first commit, deployment on our own pipelines, error tracking and monitoring wired in from day one, and continuous improvement after launch. One studio owns the whole lifecycle, so nothing falls between teams. We scope with our own tooling and commit to fixed prices that hold. When scope changes, it goes through a formal change request rather than quietly appearing on an invoice. Based in the EU, working with clients across Europe, China, Australia and the US.Looking for work in Mobile AppLocated in London, United KingdomFrom €5,000 for Mobile AppWorks in multiple industriesSpeaks English11-50 membersFulminous Software
