Best software houses in Warsaw

From their website and Clutch profile

• The homepage claims 3,000+ engineers, 800+ clients and over 25 years in business. The Polish company in KRS dates from 2017 (source).
• The homepage names only two clients, and most case studies describe an unnamed retailer, pharma company or manufacturer (source).
• Clutch lists 12 offices, with headquarters in Decatur, GA, and Warsaw among them. The site shows no office list we could open (source).
• The site lists a Microsoft partnership since 2008, plus Odoo Silver, Salesforce and AWS partnerships (source).

Clients they name: The Economist, OPED Digital Health Solutions

Verdict. Pick Itransition for Dynamics, Salesforce or ERP rollouts at company scale. For a small custom product, the 25,000 USD minimum and the global delivery model are a poor fit.

From their website and Clutch profile

• N7 Mobile publishes monthly team prices, from 15,000 PLN for product design to 200,000 PLN for advanced apps (source).
• The site has only one full case study, PLAY NOW for the PLAY operator, and shows the other clients as logos without project details (source).
• N7 Mobile sells body leasing and team leasing next to fixed-price projects (source).
• The company runs N7 Space, which writes satellite on-board software for ESA missions, and Tapioka.ai for UI testing (source).

Clients they name: PLAY, Orange, T-Mobile, Plus, Roche, Agora

Verdict. Pick N7 Mobile for OTT and mobile work, where it has the clearest pricing on this list and operator-scale telecom projects. For a small web MVP, its team prices start high.

From their website and Clutch profile

Verdict. Use Innowise for staff augmentation under your own tech lead when you need CVs fast across many technologies. Skip it when you need a partner whose past work you can verify.

From their website and Clutch profile

• BlueSoft has belonged to the Orange Polska group since 2019, together with Craftware and Essembli (source).
• Several case studies are for Orange companies, the owner, next to clients such as Canal+, Biedronka and GATX (source).

• The site shows partner logos for AWS, Microsoft, Google, MuleSoft, Salesforce and Databricks (source).

Clients they name: Orange Polska, Canal+, Biedronka, GATX, Hellenic Cables, Raiffeisen Bank

Verdict. Pick BlueSoft for corporate integration, data and managed services backed by a telecom group. For a startup or a single small product, it is too heavy.

From their website and Clutch profile

• The about page claims 3,500+ in-house experts, 2,000+ clients, 18 offices and 19 years of experience, with Warsaw as headquarters (source).
• The footer names other legal entities, UAB Andersen Soft and Andersen Germany GmbH, so the Polish company is one of several (source).
• Many case studies are under NDA, and the named ones include Deutsche Telekom and Samsung Electronics (source).
• The site announces the Claude Partner Network and AWS MSP partnership (source).

Clients they name: Samsung Electronics, Deutsche Telekom, BNP Paribas, Verivox, TUI

Verdict. Use Andersen to scale a team you lead, backed by 129 Clutch reviews. Check who signs the contract, given the thin Polish margin and the multi-entity setup.

From their website and Clutch profile

• Team size claims disagree, with 60+ on the homepage and 40+ on the about page (source).
• Develtio grew out of Green Parrot, an advertising agency, and was founded in 2017 (source).
• Half of the six visible case studies do not name the client (source).

Clients they name: Hitachi (HVAC branch), Biletyna, Kiddoways, IPMA, BNP Paribas

Verdict. Develtio fits websites and small apps, where its client reviews matter more than scale. The filings do not support the team size on the site, so ask who will do the work.

From their website and Clutch profile

• The about page gives 2016 as the founding year and lists 62 team members. KRS dates the company from 2018 (source).
• Most of the 13 case studies do not name the client (source).
• Several testimonials and Clutch reviewers are other software houses, such as Future Processing and SoftwareHut, which points to subcontracting (source).

Clients they name: Gränges, PKF Agility, Genesis, T-Mobile, Metronet

Verdict. Call Devapo for Camunda and BPM work. For a consumer app or a general product the niche does not help, and you should ask about the employee reviews.

From their website and Clutch profile

• The about page claims 100+ experts, 350+ delivered projects and 12 years on the market (source).
• The home page shows ISO 9001, ISO 13485 and ISO 27001 logos, and the medical device standard matches its healthcare focus (source).

From their website and Clutch profile

• The home page claims 80+ experts, 40+ dedicated Flutter developers and 100+ delivered products (source).

Clients they name: Credit Agricole Bank Polska, Wedel, Maspex, Shell, Virgin Money, Millennium

Verdict. Pick LeanCode when your app is in Flutter and you need enterprise process. Without a Flutter commitment, a broader product team fits better.
