ITSharkz

ITSharkz is a Polish software development shop founded in 2019, based in Warsaw, with roughly 40 developers currently available. The company started by serving local startups and SMEs, then expanded to the French market around 2020 where it has built a visible client base among scale-ups and post-Series A companies. By 2023, the firm sharpened its focus on AI solutions—GPT integration, RAG development, fine-tuning—alongside web and mobile work. In 2024 they earned CII and CIR accreditation, which enables French clients to claim R&D tax credits on projects.

The company positions itself as a dedicated team provider rather than a freelance marketplace. You hire engineers directly, not consultants. They claim developers from the "top 5%" in the EU, and their FAQ acknowledges competing on price: you'll save "up to 50%" versus Western European rates. English and French fluency is standard across the team.

Services and capabilities

ITSharkz divides its work into four buckets: dedicated IT teams, web development, mobile development, and AI solutions.

For dedicated teams, the model is straightforward—you get embedded engineers who work on your roadmap, not hired guns. They handle onboarding in less than 2 weeks on average (their stated 14-day assembly time) and integrate via Slack, Jira, Notion, and sprint-based Agile. They manage the hardware and office space by default, though they'll work on client-provided equipment if security or compliance requires it.

Web development covers React.js, Vue.js, Node.js, .NET, and Python. Their portfolio mentions design-first workflows: one healthcare client (Pauchet Santé) deployed three mission-critical platforms with "90% operational readiness at first delivery," though it's unclear whether that's a floor or a credible claim. The Medicalib case mentions integrating OpenID Connect and building a design system; JOONE involved migrating thousands of subscriptions alongside a new checkout flow.

Mobile spans React Native, iOS, and Android. Work here is sparser in their portfolio—one fitness app (FizzUp) shows up but with minimal detail.

AI is the growth vector. They offer GPT integration for chatbots and content automation, RAG development using AWS Bedrock and Azure AI, model fine-tuning, and general machine learning. No case studies show revenue impact from AI work, but the emphasis suggests it's a sales priority.

Their engagement model is primarily time-and-materials (you pay per worked day), with fixed-price contracts available for well-scoped projects. Remote collaboration is the default; they use dedicated project managers and regular syncs. Onsite onboarding is offered when needed.

Notable work

Five client testimonials appear on the site. Medicalib (healthcare): integrated government systems and regulatory logic, built a UI library and design system. CEO and CTO endorse continued partnership. JOONE (subscription e-commerce): developed a checkout system (Newcharge), built customer dashboard, migrated subscriptions successfully. CEO Carole Juge-Llewellyn praises their proactivity. Qobuz (music streaming): optimized backend, modernized desktop app, integrated cross-platform features (Qobuz Connect). CEO and CTO cite "very skilled people, competitive rates, and nearby location." Happydemics (a French scale-up): placed 4 senior Ruby on Rails developers to fill a talent gap. CTO notes they acted as true partners, not headhunters, and achieved "full CIR compliance," implying the tax credit angle resonated. Pauchet Santé (healthcare): deployed 3 platforms for hospital workflows, achieving 90% operational readiness at first delivery using a design-first approach.

These are real companies (verifiable LinkedIn presences for the named execs), but results are mostly narrative—no "reduced load time by X%" or "increased conversion by Y%" metrics in the source.

How they work

Engagement starts with a free consultation to scope the project and select developers. They kick off within 1–2 weeks depending on availability. Daily communication happens via Slack/Jira; sprint cycles follow Agile. Dedicated project managers sit in on regular syncs. They own hardware and office infrastructure unless you specify otherwise.

Pricing is time-and-materials by default (pay for worked days only). Fixed-price is an option for clearly defined scope. The FAQ states they "primarily work on a Time & Material model, ensuring flexibility." No rate card is disclosed, but the "up to 50% savings versus Western Europe" claim gives a rough ballpark.

Team and credentials

Three co-founders are named: Kacper and Victor as Managing Partners, Kamil as CTO. The site displays a roster of ~25 engineers by name and specialization—Bohdan (Lead Frontend, React), Tomasz (Tech Lead, Node.js), Vadzim (Senior Ruby), Maksym (Senior Python), and others. A security engineer (Patrycja) and QA staff (Olga, Alexis) are listed. One UX/UI designer (Yevheniia) is named.

Certifications: CIR (French R&D tax credit) and CII (French innovation tax credit) as of 2024. GDPR compliance is mentioned in blog content, suggesting awareness but not formal attestation like SOC 2 or ISO 27001.

Languages: English and French fluency across the team. Polish base (Warsaw), staffing drawn from the CEE region (the site mentions Ukranian-sounding names like Andrii, Vadzim, Viktar, suggesting some or all developers are remote across Eastern Europe, not collocated in Warsaw).
