Advance AI Direct Sales Platform Development (based in Dubai, UAE)

Debrok, an AI-powered direct sales platform for property developers Debrok gives real estate developers in the UAE a direct-to-buyer sales channel that runs alongside their existing broker network. An AI layer qualifies buyers and investors, hands warm leads to the developer's own sales team, then independently tracks each lead through to close. Buyers use it free of charge. Developers pay. What we need built: 1. Three portals: Buyer, Developer and Admin. 2. Property data engine. Developers manually enter and maintain projects and units (price, location, unit type and size, payment plan milestones, handover date, availability status). Data is stored in structured fields and queried live by the AI during conversations. 3. AI voice and chat qualification. The AI answers buyer questions using live property data and captures budget, purchase intent (investor vs. end-use), timeline and preferred unit type. Every call is recorded and transcribed, and each conversation produces a structured lead summary. Arabic and English support is required. 4. Handoff. Qualified leads pass to the developer's sales team with the transcript and summary attached. 5. Post-handoff follow-up. The AI keeps checking in with the buyer after handoff, independently of what the developer reports, to confirm deal status. Cadence is tiered by deal value: higher-value leads get longer, more persistent follow-up and milestone questions (agreement signed, deposit paid). Lower-value leads lapse to "unresponsive" faster. Stalled or evasive high-value leads escalate to a human. 6. Developer reporting. Detailed periodic reports covering leads, conversion and commission statements, plus regional benchmarking that shows each developer how they rank against others on the platform, with the underlying data anonymised. 7. Billing engine. Billing works either/or per month. In a month with no closed deal, the developer pays a flat monthly fee. In a month with a closed deal, the fee is replaced by a 2% commission on the unit value. There must be admin controls for waivers and fee adjustments to support an onboarding phase. 8. Admin portal covering developer management, AI conversation oversight, billing, disputes and platform-wide reporting. We are asking for a quote based on the above, plus a proposed technical architecture (stack, hosting, voice AI vendor and LLM approach), a phased delivery plan, and a rough estimate of ongoing per-call AI costs.
