Mainaro

Mainaro is an AI‑powered SaaS platform that helps real‑estate investors see the true after‑tax profitability of every property.

• Automated data extraction: Upload purchase contract, loan agreement and rental contract; the AI reads the key figures from the marked PDF and you confirm them.
• Deterministic financial engine: Calculates cash flow, taxes, depreciation (AfA), interest, repayment and DSCR using official German sources (BORIS, BBSR, Destatis).
• Live location score: Free, transparent demographic, economic, infrastructure and research scores for every German municipality, updated continuously.
• Portfolio cockpit: One‑glance traffic‑light view (green/red) showing whether each object carries itself after tax, with metrics like monthly after‑tax cash flow, DSCR and location score.
• Smart alerts & scenario planning: Warnings on upcoming fixed‑rate expiry, speculation period, refinancing needs and exit simulation.

Mainaro targets individual landlords, small‑scale investors and property‑management professionals who need reliable, audit‑ready numbers without becoming tax advisors. Its value proposition is turning opaque spreadsheets into clear, actionable insight — so you know exactly what remains after tax before you buy, hold or sell.
