What HelliT does

Hellit s.r.o. (operating as HelliT) is a custom software studio founded in 2011 and headquartered in Prague, Czech Republic. The studio operates as a small, senior-only team of engineers and designers (headcount stated as 11–50) that delivers bespoke software for a selective handful of projects per year, serving clients worldwide from its Prague base. The company explicitly rejects the traditional agency model: clients communicate directly with the engineers building their product, there are no account managers or project managers, and the intake process is deliberately narrow.

The studio's offering is organized around six integrated service lines: web applications (React, Next.js, TypeScript, Astro), mobile applications (React Native, Swift, Kotlin, Expo), backends and APIs (Node.js, Python, Go, PostgreSQL), system integrations (REST, GraphQL, Webhooks, ETL), AI and automation (OpenAI, Anthropic, RAG, vector databases), and product design and UX (Figma). These capabilities are delivered as a single unified engagement rather than modular products, with each project including understanding, prototyping, shipping, and post-launch operational support phases. HelliT is privately held, bootstrapped with no disclosed external funding or ownership changes since founding.

Customer segments are vertical-diverse rather than concentrated: a Southeast Asian consumer microloans platform (fintech), a remote-control device customer portal (SaaS), a state institution information system (public sector), and a computer-vision retail stock-counting system (retail/computer vision). The business model is professional services: project-based, quote-based engagements with no publicly disclosed pricing, no subscription tiers, and no recurring revenue mechanics. The company is currently operating, with an active website dated 2026 and a single inbound contact channel ([email protected]).

Core offering

HelliT is a custom software studio that designs, builds, and operates bespoke web applications, mobile applications, backends and APIs, system integrations, AI and automation solutions, and product design for companies that need working code rather than presentation decks. Engagements are project-based, delivered by a small senior team that communicates directly with clients, ships working software in weeks rather than quarters, and continues to monitor, patch, and iterate the systems after launch.

Product overview

HelliT is a custom software studio that operates as a single unified offering rather than a platform-plus-modules architecture. The studio provides six distinct but interconnected services: Web Applications, Mobile Applications, Backends & APIs, System Integrations, AI & Automation, and Product Design & UX. These services are designed to work together as an integrated stack — the design team creates the product vision and UX, which is then built as web/mobile frontends connected to backend services and third-party integrations, with AI capabilities layered in where appropriate. There are no separate product tiers, modules, or add-ons; clients engage the studio for end-to-end custom software development.

Functional benefit

Products and services

• Web Applications Custom web application development for marketing sites, internal tools, and customer-facing platforms handling real traffic. Targeted at companies needing bespoke web platforms rather than off-the-shelf SaaS, built on React, Next.js, TypeScript, and Astro with a focus on durable, fast delivery.
• Mobile Applications Native-feel iOS and Android mobile application development built once and maintained long-term, with offline-first capability where required. Targeted at companies needing bespoke mobile apps, implemented with React Native, Expo, Swift, Kotlin, Firebase, and RevenueCat.
• Backends and APIs Custom backend service and API development designed to be boring, correct, and observable. Targeted at companies needing reliable server-side logic and integration surfaces, implemented with Node.js, Bun, Python (FastAPI), Go, PostgreSQL, Redis, GraphQL, and REST.
• System Integrations Integration services connecting legacy CRMs, ERPs, payment rails, and third-party APIs with audit trails and retry logic, supporting REST, GraphQL, Webhooks, and ETL patterns. Targeted at companies that need disparate systems to interoperate reliably and auditable.
• AI and Automation Custom AI and automation solutions using large language models, agents, retrieval-augmented generation (RAG), and vector databases to move real work rather than serve as demo-ware, built to be auditable, cost-effective, and kill-switchable. Targeted at companies needing production-grade AI implementations integrated with their internal systems, implemented with OpenAI, Anthropic, Pinecone, and pgvector.
• Product Design and UX Product design and UX services covering product strategy, UX research, design systems, and interaction prototyping delivered in Figma. Targeted at companies needing both visual design and the downstream engineering that turns it into shipped software, integrated with HelliT's build services.

Direct peers

• 8th Light: Custom software consultancy staffed by experienced engineers and designers delivering bespoke web and mobile applications. Matches HelliT's craft-focused, senior-staffed studio approach to bespoke product development.
• DockYard: Digital consultancy building custom web and mobile applications with senior cross-functional teams. Directly comparable in service mix (web, mobile, backends, design) and in selective, project-led delivery.
• Atomic Object: US custom software consultancy that pairs designers with senior engineers for bespoke product builds, with ongoing collaborative partnerships. Closely mirrors HelliT's senior-studio, custom-software, long-term-engagement model.
• Thoughtbot: US-based product design and custom software consultancy built around senior developers and designers with a similar studio-style, quality-focused delivery model. Comparable in offering (web/mobile design + build) and in emphasizing small, senior teams over scaled agency hierarchy.
• Hashrocket: Small, senior-only web and mobile development studio known for high-quality bespoke builds. Comparable in size, philosophy (senior-only, no juniors), and emphasis on craftsmanship over agency scale-up.

Broad incumbents

• Pivotal Labs: Established consultancy historically known for pairing senior engineers with enterprise product teams on custom software and agile transformation. Larger incumbent offering overlapping custom-build services but at much greater scale.
• Netguru: Larger European (Poland-based) digital consultancy offering custom software, web, and mobile development with a similar client roster of fintech and enterprise buyers. Operates at meaningfully greater scale than HelliT but competes for the same mid-market and enterprise custom-build deals.
• Toptal: Global freelance talent platform connecting companies with senior engineers, designers, and product talent. Adjacent competitor for clients seeking senior-only engineering capacity, but operates a marketplace model rather than a single integrated studio.

Regional players

• Xmartlabs: Uruguay-based mobile and web product studio with a senior-engineer model serving the Americas and selective global clients. Comparable in senior-staffed bespoke delivery and in mobile/web capability mix, though primarily serving a different geography.

Emerging players

• BiggerPockets / Hanno: Small, senior-only product studio focused on healthcare and fintech web/mobile builds. Comparable in size, selective intake, and senior-only philosophy, with overlap in regulated-vertical engineering work.
