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.51 works in Software DevelopmentLocated in London, United Kingdom (+2)From €5,000 for Software DevelopmentWorked in Automotive (+18)Speaks English, French(+2)11-50 membersAzuki

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.

4.9(20 reviews)PARTNER IN CRIME FOR STRONG BUSINESSES.
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. LET'S TALK IF your business is strong but your website, brand or operations don't play at the same level yet.40 works in Software DevelopmentLocated in London, United KingdomFrom €5,000 for Software DevelopmentWorked in Hospitals & Healthcare (+20)Speaks English11-50 membersPoppins
