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.

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.

A focused practice. AI & software engineering at the core, with flexible delivery models — embedded teams, augmented squads, full project ownership — wrapped around it.

We map your goals, constraints, and success criteria before writing a single line of code.
02
Team Assembly
Engineers matched to your stack. You approve composition.
03
Development
Two-week sprints, daily standups, weekly demos.
04
Review
Demo, feedback, and refinement each sprint. You stay in control throughout.

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 under our SBS methodology.
Full-stack AI implementation: LLM integration (OpenAI, Anthropic, open-source), retrieval-augmented generation systems connecting models to proprietary data, intelligent document processing, custom ML model training, computer vision pipelines, NLP for sentiment/entity extraction, and chatbot/agent systems. Vector databases (Pinecone, Weaviate, pgvector). Every AI engagement begins with feasibility assessment and a proof-of-concept before production investment.
Step by Step (SBS) is our proprietary delivery methodology. Work is structured into sequential, reviewable milestones — each with acceptance criteria and a client sign-off gate before the next stage begins. SBS includes a 2–4 week evaluation period at the start, daily async updates, weekly live demos, and monthly strategic reviews. Same standard for project, team, and augmentation engagements.
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 5–7 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. Sizes from 2 to 20+ engineers.
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.
