Comprehensive development roadmap and technical specifications

Executive Summary

Tefi is designed to streamline the real estate bidding process in Norway by integrating with finn.no and partnering with banks. This roadmap outlines our strategy to enable bidders to start bids via finn.no's "gi bud" button, redirecting them to Tefi for verification, and implement an SMS-based verification system to confirm bids.

Business Goals

Market Penetration

Leverage finn.no's large user base and bank partnerships to attract bidders.

Automation & UX

Partner with banks to automate financing verification, eliminating manual uploads and reducing friction.

Trust & Security

Use SMS verification to ensure bid legitimacy, reduce fraud, and build confidence.

Scalability

Build flexible infrastructure supporting multiple bidders, properties, and automated loan checks.

Core Workflow
1

Bid Initiation

Finn.no redirects with property ID to Tefi

2

Verification

Tefi checks financing through bank API or manual upload

3

Notification

SMS with unique code sent for bid confirmation

4

Confirmation

Bidder enters code to confirm bid status

Bank Partnerships

Partnerships with banks provide access to dedicated APIs under PSD2 regulations. These APIs enable real-time verification of financing amounts with user consent via BankID. This automation replaces manual uploads with accurate, fast, and compliant verification processes.
