Andersen Inc.

Andersen is a Poland-based software development company with 19+ years of mobile app development experience. The firm works with clients across the US, Europe, and the UK, delivering custom software across mobile, cloud, and legacy modernization. They operate a pool of over 250+ engineers (130+ iOS, 120+ Android, 100+ cross-platform specialists, plus additional staff across other disciplines), with roughly half of their workforce at senior or leadership level.

The company's core strength is full-cycle product engineering—from discovery and requirements gathering through architecture, development, QA, launch, and ongoing support. They've shipped 90+ iOS apps, 110+ Android apps, and 80+ cross-platform projects. Their work spans fintech (a personal finance app that grew to 500,000 users in one year and raised €200M), telecom (an MVNO platform modernization that drove 30% revenue growth and 50% client base expansion), fitness (a wellness app with over 1,000 Google Play downloads), crypto (a wallet hitting 4.2 rating across 40 countries), ride-sharing and car rental platforms.

Services and capabilities

Andersen structures its offerings around distinct technical domains. Mobile development covers native iOS and Android, cross-platform (React Native, Flutter, Xamarin), hybrid apps, and progressive web apps. They cite advantages per approach: native apps deliver top performance and security but at higher cost; cross-platform offers cost efficiency and faster time-to-market with code reuse; hybrid balances speed with consistency; PWAs provide offline functionality and SEO benefits.

Beyond mobile, the firm offers AI & Data (consulting, data science, audits), Cloud Development (migration, multicloud, data protection), Software Engineering (API design, architecture, IoT, product development services), Legacy Modernization (consulting, API harmonization, refactoring, migration), and Staff Augmentation (back-end, front-end, QA, UI/UX). They also work in GIS development, healthcare AI (including early Alzheimer's diagnosis via medical imaging), and domain-specific solutions.

Their delivery process follows a defined sequence: Discovery (business goals, user research, competitor analysis), Requirements Specification (scope, feature priorities, acceptance criteria), UX/UI Design (wireframing, prototyping, user validation), Architecture (system design, data modeling, security), Front-end and Back-end Development, Integrations (payment tools, analytics, third-party APIs), Quality Assurance (end-to-end testing, manual and automated), Launch, and Scale (performance tuning, ongoing support).

Andersen positions itself as industry-agnostic, listing deep case material for Finance (banking software, InsureTech, FinTech), Healthcare (TeleHealth, hospital systems, EHR/EMR, mobile apps), Media & Entertainment (VOD, live streaming, digital asset management), Telecom (BSS/OSS, channel management), Logistics (transportation, warehouse, supply chain, order management), Automotive (ADAS, in-vehicle infotainment, powertrain), Life Sciences (clinical trial systems, pharma, MedTech), eCommerce, Retail, Manufacturing, Travel & Hospitality, iGaming, eLearning, Real Estate, Aviation, Oil & Gas, Legal, Agriculture, Construction, Energy, GIS, and Public Sector.
