Get a custom proposalAI-native SaaS & product engineering in weeks
Onpolar is the senior product engineering partner companies hire when they need real software shipped — not slide decks, not pilots that die in prototype. We own the full stack: architecture, backend, frontend, infrastructure and the AI layer.
WHAT WE BUILD
- AI-Native SaaS — multi-tenant products with agentic workflows, permission-aware context, billing and compliance
- Full-Stack Product Engineering — landing page to multilingual platform, MVP to production scale
- Generative Engine Optimization (GEO) — get cited by ChatGPT, Claude, Perplexity and Gemini as traditional SEO bleeds clicks
- Big Data & ETL Pipelines — public datasets, CRM exports and event streams into reliable product surfaces
- Vibe Code Rescue — Lovable, Bolt, v0 and Cursor prototypes refactored into modular, type-safe, tested production architecture
WE BUILD AND OPERATE OUR OWN PRODUCTS
ERPFlow.ai — multi-tenant SaaS ERP with EU Peppol BIS 3.0 e-invoicing, per-seat Stripe billing and 19 UI languages. API-first: 300+ endpoints behind one OpenAPI contract. Shipped in 2 months.
Deal.ee — AI-indexed Estonian business platform: ~368,000 companies from 19 government datasets, refreshed daily across ~2.2M URLs, built to be cited as a primary source by AI assistants.
Running our own products keeps us honest about what "production" actually means.

Our Story
We started Onpolar because too much software gets sold and never shipped — slide decks, pilots that die in prototype, teams that vanish for six months.
So we built the opposite: a small senior team that owns the whole stack — architecture, backend, frontend, infrastructure, AI — and ships in weeks.
We also build and operate our own products, ERPFlow.ai and Deal.ee, which keeps us honest about what "production" actually means.
Right tool for each job, not the trendy one.
