many-to-many is a software development and technology management service run by Vitalii, with the legal entity many-to-many sp. z o.o., registered in Wrocław, Poland. It is not a traditional self-service developer tool or SaaS product. Instead, it operates more like “CTO as a Service + development team”: a professional CTO joins the client’s team to provide technology strategy, architecture decisions, and project management, while an accompanying development team handles mobile, web, backend, and design work.
Its services cover mobile development, web development, backend development, UI/UX, product design, cloud computing, GIS, AI/ML, AR, and IoT. The website explicitly lists capabilities including React Native, Expo, Native iOS, Native Android, ReactJS, NodeJS, Ruby on Rails, Python/Django, Golang, AWS, and Google Cloud. Its case studies also mention integrations and technologies such as Swift, Objective-C, Next.js, Firebase, MySQL, Mapbox, Stripe, Apple Pay, FastSpring, CloudFront, and Bluetooth LE. Overall, it is better suited to business projects that need multi-platform product delivery, technology selection, and long-term maintenance.
The website does not publish fixed packages, hourly rates, or minimum budgets. It only states that quotes can be requested via a form, a scheduled call, or [email protected]. Its positioning emphasizes being cost-effective, avoiding expensive agencies and over-engineering, and client testimonials mention good value and fair pricing. However, there is no directly comparable pricing information available. In terms of delivery, the team is distributed remotely across Central and Eastern Europe, standard working hours are CET, and asynchronous communication is preferred.
The main advantage is that its case materials are fairly solid: National Parks App, CourtsApp, Stirred, iAwake, Bitsboard, and other projects demonstrate experience with complex scenarios such as maps, offline functionality, audio streaming, payments, cross-platform development, CMS, and wearables. There are also verified reviews on Clutch, LinkedIn, Upwork, and GoodFirms. The downside is limited service transparency: pricing, payment methods, SLA, delivery process, and contract details are not fully disclosed. It also does not offer a public API/SDK or self-service product capabilities.
It is suitable for startups without a CTO, product teams looking to launch an MVP quickly, companies that need someone to take over and maintain existing mobile/web applications, and projects with limited budgets that still need experienced technical leadership. For Chinese clients, the website does not explain access, payment, or cross-border contract details, so china_access can only be considered unknown. The CET time zone may also create communication delays. If a localized alternative is needed, options include domestic software outsourcing teams, independent CTO consultants, or global remote developer platforms such as Toptal, Andela, and Arc.dev.
