About StepTo

An AI-first
software house.

StepTo is a software engineering company founded in Belgrade in 2014. We build serious software — production AI systems, custom platforms, and dedicated engineering teams — for European and North American clients.

A 15-20 person engineering team runs every engagement out of Belgrade, working the CET time zone with 6+ hours of daily overlap for US East Coast clients. Long-term client retention sits at 95% — most clients who start with StepTo stay for years.

Our focus has shifted firmly toward artificial intelligence and high-performance software: LLM integration, RAG pipelines, agentic workflows, and custom ML models. Outstaffing and outsourcing are part of how we deliver, not the headline.

Every engagement runs on the same governance model — transparent milestones, weekly demos, and full IP ownership for the client. One company, one method, one standard of delivery.

Capabilities

From AI architecture to engineering teams that ship.

StepTo delivers AI and software engineering through five models: embedded teams, augmented squads, full project ownership, dedicated teams, and staff augmentation — each built around the same senior, direct-hire engineers regardless of contract structure.

Stack

Modern, opinionated, production-grade.

StepTo engineers ship on a curated stack — TypeScript, Python, React/Next.js, and cloud-native infrastructure — chosen for production reliability, not novelty.

01AI / ML

Our AI/ML stack centers on production-grade tools: OpenAI and Anthropic for LLM integration, LangChain and LlamaIndex for orchestration, PyTorch and TensorFlow for custom model training, and pgvector/Pinecone for vector databases.

OpenAIAnthropicLangChainLlamaIndexPyTorchTensorFlowpgvectorPinecone
02Languages

We use strongly typed languages for scalable applications: TypeScript for full-stack development, Python for AI and backend, Go for high-performance services, Java for enterprise systems, and C# for .NET applications. 15-20 engineers proficient across all.

TypeScriptPythonGoJavaC#
03Frontend

Modern frontend frameworks for responsive UIs: React and Next.js for component-based development, Angular for enterprise apps, Vue for lightweight projects, and Tailwind for utility-first styling.

ReactNext.jsAngularVueTailwind
04Backend

Scalable backend technologies: Node.js for JavaScript ecosystems, FastAPI for Python APIs, Spring for Java enterprise, GraphQL for efficient data fetching, and REST for standard web services.

05Data

Robust data infrastructure: PostgreSQL for relational data, MongoDB for documents, Redis for caching, and Kafka for streaming.

06Cloud

Multi-cloud expertise across major platforms: AWS for comprehensive services, GCP for AI/ML, Azure for enterprise integration, and Cloudflare for edge computing.

FAQ

Questions, answered straight.

Five core service lines: AI & automation (LLM integration, RAG, custom ML — the headline practice), custom software development (web, mobile, enterprise), dedicated development teams (fully managed engineering teams), outstaffing/staff augmentation (engineers embedded in your team), and end-to-end software outsourcing. All delivered by the same senior, direct-hire engineers regardless of engagement model.
Full-stack AI: LLM integration with OpenAI/Anthropic, RAG systems, custom ML training, computer vision, NLP, and chatbots. Uses vector databases like Pinecone and pgvector. All projects start with a feasibility assessment and proof of concept before moving to production.
Five stages. A 60-minute discovery call (day 1-2) to define requirements and engagement model. Talent matching within five business days — you get 3-5 pre-vetted candidate profiles, already screened through a three-stage technical process. A two-week paid trial once you select an engineer, with equipment, access, and contracts handled in parallel. Full engagement, where your team integrates into your sprints and reports directly to you, with monthly account-manager check-ins. Ongoing growth and scaling through quarterly roadmap reviews as your needs change.
40–60% savings vs. equivalent Western European, US, or UK engineering hires. A senior US full-stack engineer's fully loaded cost often exceeds $280k/year; a comparable StepTo engineer is $55–85k/year, fully managed. For a 5-engineer team that's $500–700k in annual savings. Pricing is transparent, contracts adjust monthly, and there's no long-term lock-in.
Four steps. (1) You share requirements: stack, seniority, team size, domain. We shortlist within 5 business days from our pre-vetted talent pool. (2) You interview and decide. (3) Onboarding into your tools, codebase, sprints. (4) Your team operates on your schedule, reports to your leads. We provide a dedicated account manager. Most teams reach full productivity in 2-4 weeks, sized to fit your project rather than a fixed headcount.
Outsourcing is project handoff: you define the deliverable, we build it. Outstaffing/augmentation is people: you get dedicated engineers working exclusively for you while we handle payroll, HR, and compliance. With outstaffing, you set priorities and run standups exactly as with an in-house hire. Best for companies with strong technical leadership who need to scale capacity quickly without permanent headcount commitments.
