Zaven

Zaven is a Poland-based custom software development company founded 15 years ago with 40+ team members and €3.3 million in annual turnover (2023). The firm delivers roughly 10 projects per year for startups, scale-ups, and mature technology companies, focusing on web and mobile applications, AI integration, and legacy system modernization. Rather than selling off-the-shelf solutions, Zaven positions itself as a process-driven partner that works through technical briefings, detailed specification, planning sign-off, and sprint-based delivery with regular demos.

Services and capabilities

Zaven's service portfolio spans three main areas. For early-stage companies, the firm builds MVPs and prototypes, offering software prototyping and MVP development. For scale-ups and established tech companies, Zaven handles team scaling through staff augmentation, dedicated teams, and offshore development center (ODC) setups. The company also offers DevOps as a Service, Legacy Software Maintenance, and Legacy UI Modernization.

Two specialized services stand out. Custom MCP Server Development bridges proprietary internal systems to AI agents—connecting legacy SQL databases, APIs, and custom business logic to large language models through secure, purpose-built integrations rather than generic wrappers. Zaven implements zero-trust permissions so AI agents only access what they need, and handles deployment of scalable remote servers using Server-Sent Events (SSE). The company is explicit about timelines: a prototype connecting one clean API to an agent takes roughly two weeks; production-grade deployment with authentication, logging, and human-in-the-loop safeguards usually takes 6–10 weeks.

Generative AI Software Development focuses on moving beyond chatbots. Zaven applies prompt engineering for reliability, uses retrieval-augmented generation (RAG) to prevent hallucinations, integrates with Azure OpenAI Service, and optimizes token performance for cost control. The firm emphasizes that custom AI solutions differ fundamentally from generic ChatGPT subscriptions—enterprise workflows require tailored integration, not generic endpoints.

Data Visualisation services include custom interactive dashboards, data storytelling, actionable insights through visual analytics, and seamless integration into existing infrastructure. Named projects include InflowNet (water network analytics suite), Dionach Draco (cybersecurity audit portal), and Primayer Eureka (tablet app for water leak location).

Notable work

Zaven's case studies span utilities, healthcare, construction, real estate, and cybersecurity. For Volve, the firm built an MVP web application using LLM-powered AI for tender document analysis in construction and real estate—facilitating deep document analysis and bid comparison. The tech stack included .NET, Azure SQL, OpenAI, and React.

For Grasp AS, Zaven rebuilt an iOS application and extensive back-end systems. A designer and researcher at the firm noted the team's "tremendous know-how" and close cooperation on project progress. For Fonn, Zaven delivered a system where the CEO stated the "technical solution or team could not have been better chosen"—citing choice of technology, pace, cost, and quality as "beyond anything we've seen earlier." Bonduelle's Product Specialist reported over a year of partnership and willingness to continue working together.

How they work

Zaven operates three engagement models. Project-based: time & materials budgeting, team setup including BA and QA, agile project management by Zaven, code ownership (repo, CI/CD, testing environment), and communication through a Project Manager. Staff augmentation & dedicated teams: FTE-based commitment (monthly, part-time), on-demand recruitment with no extra fees, client manages tasks, no handover costs, and optional Build-Operate-Transfer option with HR as the communication point. Offshore Development Center: Zaven guides clients through establishing a foreign subsidiary for knowledge retention and business continuity.

Contact response time is 8 business hours (GMT+1, Monday–Friday 9am–5pm). Initial process: technical briefing to define scope, specification with follow-up questions, planning and cost/schedule sign-off, then sprints with demos. Intro call is 20 minutes; expert call is 30–60 minutes; proposals come within 3–5 business days.
