Best legacy application modernization companies in Poland

From their website and Clutch profile

• CSHARK focuses on two sectors, fintech/regtech and industrial, and Fenergo appears in two separate case studies (source).
• CSHARK is the only firm in the set with an Asian office, CSHARK Singapore Pte. Ltd on Robinson Road (source).
• The homepage shows logos of Citibank, Allianz, BNP Paribas and Vodafone, but none of them has a case study, so treat them as unverified (source).
• The site states no headcount, while Clutch lists 250 to 999 employees and a USD 50k minimum project (source).

Clients they name: Fenergo, ASA International, Telenor, RegenHU, Nudge, Pastdue Credit Solutions

Verdict. A mid-size house for regulated industries, with ISO 27001 to show for it. Come with a budget above 50,000 USD and a compliance checklist, not a two-month MVP.

From their website and Clutch profile

• Headquarters are in Kraków, and Wrocław is one of two Polish development centers. Grape Up has a Wrocław presence but is not a Wrocław company (source).
• 24 of 25 case studies are anonymized by sector, and Cummins is the only named client. The homepage logo wall shows image files without text names (source).
• The about page claims over 20 years of operation but gives no year. The Polish KRS entry is from 2014, and Clutch lists 2006 (source).
• The site shows no ISO or cloud partner certifications, although Grape Up sells sovereign cloud and AI governance products (source).
• Clutch shows 5.0 from 6 reviews, a $50,000 minimum project, $50 to $99 per hour and 50 to 249 employees (source).

Clients they name: Cummins

Verdict. Grape Up is profitable but hard to verify from outside, so ask for named references in your industry before you sign. For a startup MVP it is too big.

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 home page offers to act as a dedicated in-house team and to give access to software professionals. (source)
• Case studies cover claims processing for 22 million customers and postal shipping, without client names. (source)
• The careers page lists Java, data warehouse and ServiceNow roles, one located at a client office park. (source)
• The contact page gives NIP 5272712409 and Jasna 14/16a, matching the register. (source)

Verdict. Use Clurgo to add Java engineers to a bank or insurer modernization program. Skip it for a startup MVP.

From their website and Clutch profile

• The Polish page lists consulting, funding and digital solutions as its three areas (source).
• KRS 0000989737 and NIP 5272670467 on the page match the registry record (source).
• Named Polish clients include Greenvolt, Polenergia eMobility and METRANS, mostly on funding projects (source).
• The group site claims 750+ team members across consulting, funding and digital work (source).

Clients they name: Greenvolt, Polenergia eMobility, GRENERGY, METRANS (Polonia), FreshMail, Enetecs

Verdict. Pick Civitta when a digital project depends on EU or national funding. Look for a dedicated software house if you only need code.

From their website and Clutch profile

• The home page claims 16 years on the market and 15 developers with 8 years of average seniority (source)
• Case studies report an 83% load-time cut for NotebookRank and 40% faster time to market for Placker (source)
• Google Cloud appears only as a technology option, with no partnership stated (source)
• The about page links a Docker e-book and the PHP at Scale newsletter (source)

Clients they name: Placker, NotebookRank, MediaHQ, Skylegs, WorkPanda, Healthgraphic

Verdict. Pick Accesto to rescue a PHP SaaS that slows down as it grows. For a new app outside PHP, look elsewhere.

From their website and Clutch profile

• The about page says seven ASP.NET and PHP developers founded the company in 2002. (source)
• The about page names ISO 27001, ISO 27701 and ISO 9001 but describes the accreditation as started in 2026. (source)
• The home page offers a dedicated center from 8 engineers and staff augmentation from 1 engineer. (source)
• The Warsaw address on the site, Hoża 86/410, matches the registered address in KRS. (source)

Clients they name: Shell, Clarivate, Auction.com, MedPro Group, DIGATEX

Verdict. Pick Azati to modernize an insurance, banking or energy system with AI. Look elsewhere for a small web job under its 10,000 USD minimum.

From their website and Clutch profile

• makimo.pl redirects to makimo.com, and the Łódź address appears only in the privacy policy (source).
• Makimo sells its services as named packages, such as a health check and a care plan (source).
• Makimo is an AWS Select Tier partner and a SoDA member (source).
• The listed broker XTB appears as a named case study (source).

Clients they name: XTB, Tune Therapeutics, Vanderbilt University, Winicjatywa, MISZBUD

Verdict. Hire Makimo to fix and maintain a product you already run. For a large new build, its small size becomes the limit.

From their website and Clutch profile

• Software Mind was founded in 1999 in Kraków as Websoft. Private equity firm Enterprise Investors invested EUR 25 million in 2020 (source).
• The site claims 1600+ experts and ISO 9001, ISO 14001 and ISO 27001 certification (source).
• Polish offices are in Kraków, Warsaw, Rzeszów and Wrocław. The contact page also lists the US, Germany, Romania, Moldova and Latin America (source).
• The legal entity is Software Mind S.A. with KRS 0001180898, which explains the recent registry date in our file (source).

Clients they name: Backbase, T-Mobile, Orange, nShift, CERN, Baillie Gifford

Verdict. Pick Software Mind for telecom, finance or media programs that need many roles and certifications. For an MVP or a single small app, it is too big.

Verdict. Strongest on transparency and specialization. Weakest axis: activity (1.5/5).
