RST Software

RST Software is a Polish custom software development shop founded in the late 1990s (20+ years in operation). The company has 180+ regular and senior engineers spread across its operations. It works with startups and established companies to build MVPs, SaaS products, web and mobile applications, and handles cloud infrastructure and process automation. Clients include Kitche (food waste app), CarFellows (car rental e-commerce), EasyTranslate (translation platform), and City Pantry (UK-based food ordering). The company maintains a portfolio of 20+ case studies across industries ranging from fintech to mobility-as-a-service.

Services and capabilities

RST breaks its offering into several buckets. MVP development—their stated focus—covers product workshop (1-2 days), wireframing (4-7 days), UX/UI design (7-14 days), MVP build (2-6 months), and launch-day support. They estimate MVP timelines from two to six months and costs from $40,000 to $300,000+. SaaS development includes strategy consulting, custom builds, architecture design, integration, QA, and deployment. They offer dedicated SaaS cloud services: cloud migration, security, infrastructure design, serverless computing, performance optimization, containerization.

Location-based services form a vertical specialty—they work with map platforms (OpenStreetMap, Mapbox), geospatial mapping, and spatial data visualization. They also build chat apps, video streaming platforms, and logistics software. Process automation is handled through Camunda Platform (BPM) implementation. Web stack covers React, Next.js, Nuxt.js; mobile includes React Native and Flutter; backend includes Node.js, PHP, Java; cloud includes AWS and GCP.

Delivery methodology centers on Scrum-oriented teams. Project managers and developers report directly; a dedicated Agile PM is available daily. Budget oversight and schedule accountability are stated commitments. QA specialists are assigned during development. They promise demos and PM reports throughout.

Notable work

Kitche (co-founder Alex Vlassopulos): RST built a mobile app for food waste reduction and household savings. CarFellows (CEO Derek Devlin): an e-commerce platform for car rentals targeting the German market, described as paperless and available across devices. EasyTranslate (CEO Alex Nazaruk): a multi-platform solution connecting businesses with language professionals globally. City Pantry (UK): head of engineering David Stefan noted the team was "responsive to our needs and requests, solving problems quickly." SkyHome: an online tool for interior designers covering project management in a single interface. Trash: RST built the content creation component and a customized AdminJS panel. Scalerr and Clara were also mentioned, though details were limited.

Their portfolio lists 20+ case studies (Trans.eu, Bussr, VSCO, BetterTaxi, Klar, Alphabet, Son of a Tailor, RWS Group, Transcash, and others), suggesting sustained client retention across multiple sectors.

How they work

For MVP projects, the process is structured: begin with a product workshop to align vision and identify technical risks; move to wireframes and clickable prototypes (days, not months, they claim); proceed to UX/UI and specs; then development with a QA specialist embedded. For longer engagements, they offer staff augmentation (regular and senior engineers), SaaS consulting, or dedicated team models. Pricing is project-dependent (MVP estimates noted above); for SaaS, no standard rate card is listed—engagement is scoped post-consultation. Communication is handled via Agile rituals and direct team access. Clients own all source code and deliverables upon completion, including design assets and documentation.
