WEZOM

WEZOM is a software development company founded in Poland with operations across the US (Chicago, New York, Houston) and a team of 275+ full-time professionals. Over 26 years, the company has completed 3,500+ projects for clients ranging from small businesses to enterprises. The team includes consultants, architects, programmers, data specialists, cybersecurity experts, DevOps engineers, and QA professionals. WEZOM says clients see an average x2 annual revenue boost, and they work with 250+ clients on engagements lasting at least three years.

Services and capabilities

WEZOM's core offerings span six areas. Software development covers IT consulting, scoping sessions, product development, MVP work, maintenance, and SaaS builds including custom CRM systems. Web development includes web applications, front-end work, progressive web apps (PWAs), single-page applications, web portals, and corporate sites. Mobile app development covers iOS (native), Android (native), Flutter, cross-platform, AR/VR apps, and wearable solutions. The company operates a data science and AI practice: AWS and cloud work, big data solutions, IoT development, AI chatbots, and generative AI. They also offer QA and testing (test automation, functional and performance testing, load testing, cybersecurity), and UX/UI design (product design, rapid prototyping, web and mobile design).

WEZOM structures projects through a seven-phase process: discovery (requirements analysis and competitor research), UX/UI design (web, desktop, mobile), web development, mobile development, AWS and cloud consulting, test automation (unit, end-to-end, and integration testing), and product-to-market launch. Project timelines vary: they estimate 2–3 months for simple solutions (like one-pagers), 3–6 months for average complexity (e.g., SMB e-commerce), and 9+ months for complex projects (feature-rich apps, marketplaces). The company follows a shift-left QA approach and ISO 9001 quality standards.

Notable work

WEZOM's public case studies include Seoul Bloom, a mobile e-commerce app for a Korean cosmetics distributor. The app added a loyalty program and personalized customer engagement; results showed a 14% higher average order value in the app versus the website, with 29% of all online sales shifting to the app. For an unnamed client, WEZOM built an online store with 1C and amoCRM integrations, plus market analysis and site mapping; the client reported sales growth of 65% and conversion increases of 150%. The company also developed the WEZOM AI Chatbot, a generative AI chatbot for automated lead qualification that reduced lead qualification time by 40–60%, and VoicePilot AI, an AI voice agent for customer support. An AssetGuard AI computer vision solution for real-time heavy machinery detection achieved 100% automation of asset monitoring missions on edge devices. Another case involved WRKfor, an integration and support platform for migrants and refugees with mental health services.

How they work

WEZOM engages clients on a project basis, with pricing determined by scope, required skills, team size, timeline, and additional needs (consulting, migration, management). The company offers discovery consultations at no cost. Typical engagements involve a dedicated project team drawn from their 44 front-end developers, 55 back-end developers, QA specialists, and other disciplines. Client testimonials note clear prototypes upfront, transparency on deliverables, and flexibility; one client praised the team's willingness to iterate across multiple projects including a CRM with desktop and mobile versions plus iOS, Android, and web server applications.
