What Teonite does

Teonite (legal entity: teonite services sp. z o.o.) is a Polish deeptech software studio headquartered in Szczecin, Poland, founded around 2010 and operating with 11-50 employees. The firm provides custom software development services spanning Rust, Python, Go, and React.js, alongside specialized R&D execution and technology due diligence, targeting enterprise and technology-company clients across FinTech, SpaceTech, Blockchain, MedTech, and security verticals. Its client portfolio includes T-Mobile Poland (predictive store-location profitability modeling), the European Space Agency (open-source SDR mobile app), the UltraViolet/DECE consortium of six major Hollywood studios, Casper Blockchain (smart contract validation), home.pl (MFA platform), Foxtral (Rust-based crypto exchange engine at 200k TPS), and Qvistorp Growth (portfolio management with Monte-Carlo simulations), among others.

Teonite combines professional services with two proprietary product lines: Defguard, an open-source enterprise SSO and VPN platform with first-of-its-kind native MFA for WireGuard (TOTP, Email, WebAuthn/FIDO2, Web3 wallet authentication, OpenID Connect, OpenLDAP sync), and Deep-Image.ai, an AI-driven image enhancement and generation tool. The technology stack is Rust-heavy (also Python, Go, React.js, Kubernetes, Docker, AWS), and the team maintains open source contributions such as the wireguard-rs library and Casper blockchain node work. AI/ML capabilities are applied across modalities including computer vision, predictive modeling (XGBoost), LLM integration (ChatGPT, Groq, Gemini), NLP, anomaly detection, and quantitative optimization (GARCH, Black-Scholes-Merton, Monte-Carlo).

Teonite operates a quote-based, consultative go-to-market model with co-founders (Robert Olejnik, Executive Chairman; Michał Gryczka, New Business) personally engaged in client acquisition. Engagements are typically scoped through discovery and design workshops prior to project commitment, and projects are billed as professional services with no publicly disclosed pricing. There are no disclosed funding rounds, external investors, or acquisition activity, indicating a bootstrapped, founder-owned firm. Revenue, contract values, ARR, and headcount growth metrics are not publicly disclosed; marketing is conducted through content (case studies, blog), developer relations (GitHub open source), and direct enterprise outreach via Calendly.

Broad incumbents

• Thoughtworks: Global custom software and digital transformation firm with a similar premium engineering positioning and consulting-led discovery model. Comparable as a high-end outsourced software partner serving enterprise clients across multiple verticals.
• EPAM Systems: Large IT services and custom software development firm with deep Central/Eastern European engineering hubs (including Poland). Closely comparable business model of premium enterprise software development with vertical breadth.
• Keycloak: Open-source identity and access management project under CNCF with broad enterprise adoption (Red Hat SSO). Competes with Defguard in the SSO/identity space, but with a much larger ecosystem and backing.

Direct peers

• SoftwareMill: Polish boutique software consultancy with a strong Rust and Scala focus, including open-source contributions (e.g., sttp, cats-effect ecosystem). Most directly comparable peer given shared Polish base, Rust specialization, and boutique services-plus-open-source model.
• Infinum: Croatian-rooted, Central-European software engineering agency delivering custom software across mobile, web, and emerging tech. Comparable in scale, multi-vertical enterprise services focus, and Central European delivery model.
• Tailscale: Commercial product built on WireGuard for VPN and zero-trust networking. Directly comparable to Teonite's Defguard product (also WireGuard-based), competing for the same identity-and-secure-network buyer.
• Authentik: Open-source identity provider / SSO provider with a strong developer community and self-hosted focus. Closest open-source functional competitor to Defguard's OIDC and identity-management capabilities.

Regional players

• Boldare: Polish product development and design studio serving European and international clients with custom software, UI/UX, and discovery-led engagements. Comparable in scale, Central-European delivery, and consultative services model.

Emerging players

• JetBrains: Developer tooling company with deep investment in the Kotlin and Rust ecosystems. Comparable as an ecosystem player where Teonite engineers contribute (Rust, Kotlin SDR mobile app), and as a competitor for top-tier Rust engineering talent in Central Europe.
• Andela: Global marketplace/platform for vetted senior engineering talent, often competing with boutique agencies like Teonite for the same enterprise custom-development RFPs with a tech-led, talent-network positioning.
