How we selected these companies

Each company was assessed against six criteria, using public information (company websites, Clutch profiles, published case studies and financial reports):

1. Team size and delivery capacity

   : can the firm staff the project at the scale you need?

2. Delivery model

   : dedicated teams, team augmentation, full-cycle ownership, or managed services.

3. Security and compliance

   : certifications such as ISO 27001, an EU legal entity and GDPR readiness.

4. Verified client outcomes

   : named clients and published results, not just logos.

5. AI maturity

   : whether AI is used in the firm’s own engineering process, not only sold as a service.

6. Industry depth

   : proven experience in regulated or complex domains.

Boldare

Gliwice, Poland (also Warsaw, Wrocław, Kraków) | Founded: 2004 | Team: ~80 | boldare.com

Boldare is a Polish product design and software development company. It works as one cross-functional, self-managing team that owns the whole product lifecycle, from discovery and MVP through scaling, legacy modernization and post-launch iteration. Scrum has been part of its delivery since 2010.

Verified client outcomes:

• BlaBlaCar

  : Boldare teams delivered 10 products for 27 countries in 18 months. BlaBlaCar became the market leader in its target regions and grew its user base from 24M to 35M. (

Enterprise readiness:

• ISO 27001 certified
• AWS-certified infrastructure work
• Member of the Claude Partner Network: AI tools are used across Boldare’s own coding, design, testing and delivery
• 430+ client relationships since 2004, and 80% of clients return for their next product
• 63 verified reviews on Clutch
• EU legal entity, with full working-day overlap for European clients

Services: product discovery and workshops, MVP development, full-cycle SaaS development, UX/UI design, AI and agentic AI implementation, LLM integration, legacy modernization with AI, cloud architecture and DevOps, team augmentation, and post-launch maintenance.

Best for: enterprises that want one accountable senior team across the whole lifecycle, rather than separate strategy, design and build vendors.

Worth knowing: with around 80 people, Boldare is not built to staff simultaneous rollouts in dozens of countries. For that scale, see Sopra Steria or Avenga below.

2. Sopra Steria

Paris, France | Founded: 1968 (Sopra; merged with Steria in 2014) | Team: 58,000 | soprasteria.com

Sopra Steria is one of Europe’s largest IT services and consulting groups. It combines consulting, systems integration and managed services, with long experience in banking, insurance, defense and public-sector programs.

Best for: organizations that need one partner for very large, multi-country IT programs with formal governance.

Worth knowing: at this scale, engagements are typically structured as large programs. Smaller product initiatives may get more senior attention from a mid-sized firm.

Avenga

Praha, Czech Republic | Founded: 1992 | avenga.com

With over three decades of enterprise delivery experience and a network of 6,000+ specialists across 40+ locations, Avenga is built for complex international programs requiring consistent governance and follow-the-sun execution across geographies.

Their defining strength is a strategy-to-operations model – they don’t hand off a technology recommendation and step aside. The same partner carries the engagement from initial consulting through legacy modernization, cloud migration, and managed services post-deployment. For enterprises running multi-year transformation programs, that continuity significantly reduces coordination risk.

AI and cloud capabilities are embedded throughout their delivery stack, with particular expertise in regulated environments where adoption must balance innovation with compliance – a balance many firms struggle to achieve.

Software Mind

Kraków, Poland | Founded: 1999 | Team: 1,600+ experts | softwaremind.com

Software Mind provides cross-functional engineering teams that embed into a client’s internal structure. Its main sectors include financial services, telecommunications, media and utilities. It holds a 4.9 average from 58 reviews on Clutch.

Best for: fintech, telecom and other complex backend systems where the vendor’s team has to work as part of an in-house engineering organization.

Spyrosoft

Wrocław, Poland | Founded: 2016 | Team: 2,000+ | spyrosoft.com

Spyrosoft is a fast-growing software engineering company listed on the Warsaw Stock Exchange. It specializes in embedded and cloud solutions, AI and machine learning, and cybersecurity, with strong exposure to automotive, Industry 4.0, aerospace and financial services.

Best for: enterprises with embedded, automotive or industrial software needs.

Full Scale

Kansas City, USA / Cebu City, Philippines | Founded: 2018 | fullscale.io

Full Scale provides dedicated offshore engineering teams that work like in-house hires. It reports more than 200 clients served, over 2 million hours delivered and a 98% client satisfaction rate. Developers are matched to the client’s culture and workflow, not only to technical requirements.

Services include custom enterprise software, SaaS, ERP and CRM platforms, React Native and web applications, legacy modernization and staff augmentation.

Best for: enterprises that want to extend engineering capacity at a lower cost base.

Worth knowing: delivery is based in the Philippines, so time-zone overlap with European teams is limited.

Orangesoft

Warsaw, Poland / San Francisco, USA | Founded: 2011 | orangesoft.co

Orangesoft has built a well-defended niche: compliant digital product development for regulated industries. With 300+ mobile and web applications delivered and deep expertise in HIPAA, GDPR, and healthcare data standards, they bring domain-specific engineering discipline that generalist firms simply can’t replicate.

Their approach keeps compliance embedded at every layer of the product – from strategy through DevOps – rather than treating it as a final-stage checkbox. For digital health companies especially, this matters: the cost of fixing a compliance gap in a clinical system after the fact is vastly higher than engineering it correctly from the start.

Frequently Asked Questions (FAQ)

What should a CTO look for in an enterprise software development partner? Technical skill is the baseline. Also check the delivery model, security certifications (such as ISO 27001), verified client outcomes, and how the firm handles changing requirements. Strong long-term partners have stable, self-managing teams and clear escalation paths.

Is a mid-sized software house suitable for enterprise projects? Yes, when the project needs one senior team fully engaged rather than a large rollout. A company of around 80–200 people, such as Boldare, can own a product end to end and work closely with your architects. For programs that need thousands of people in many countries at once, a large integrator such as Sopra Steria or Avenga is a better fit.

Which certifications matter for enterprise software vendors in Europe? ISO 27001 (information security) is the most common requirement in enterprise procurement. Also check GDPR readiness, an EU legal entity for contracting and data residency, and cloud partner status (AWS, Azure or Google Cloud).

How do I assess offshore or nearshore development teams for enterprise work? Look for dedicated teams (not shared resource pools), real time-zone overlap, low team turnover, and long client relationships. Nearshore teams in Poland or Czechia give European companies a full working-day overlap, while offshore teams in Asia usually offer lower rates with less overlap.

Which firms specialize in legacy system modernization? Avenga and Sopra Steria handle modernization as part of large transformation programs. Boldare modernizes legacy systems as part of a full-cycle product engagement, including AI-assisted refactoring, which suits organizations that want to modernize and keep evolving the product in parallel.

How can I tell if a firm is AI-ready or only AI-marketed? Ask how AI tools are used in the firm’s own delivery: coding, code review, testing and documentation. Then ask for measurable results. A firm with AI built into its engineering process will show concrete numbers, not only a list of AI services.

What are the biggest risks of choosing the wrong development partner? Scope lock-in, compliance gaps found after go-live, and architecture decisions that don’t scale, which often force costly rewrites 18–24 months later. Reduce the risk at selection: ask for verifiable experience in your industry, end-to-end delivery ownership, and references from clients of a similar size.
