In productionClient-owned codebase
AI Revenue & Quotation Platform — AI lead qualification interface with conversation summary, requirements extraction, scoring and recommended next actions
AI lead qualificationAuto-qualified leads · ready for quotation
Challenge

Interior design firms were spending significant time manually responding to enquiries, qualifying leads, reviewing floor plans, preparing quotations and following up with prospects. Response times varied, lead quality was inconsistent, and sales teams were spending too much time on administrative work instead of closing projects. The result: slow response times, lost revenue from missed follow-ups, poor visibility into the pipeline, and difficulty scaling without hiring more staff.

Solution

Designed and implemented a complete AI-powered revenue operating system that captures leads automatically, qualifies opportunities using AI, extracts project requirements, analyses uploaded floor plans, generates quotation recommendations, scores lead quality, prioritises sales opportunities, automates customer communication and gives management full visibility across the sales pipeline.

Challenge

Most investment simulation and financial education tools are fragmented across spreadsheets, charting platforms and disconnected market data sources. Users struggle to model scenarios, test strategies and understand outcomes in a single system — making structured training, portfolio analysis and decision evaluation slow, inconsistent and difficult to scale.

Solution

Visileo designed and developed a unified investment simulation platform that combines portfolio management, market analytics, scenario modelling and trading workflows into a single environment. Users can build and monitor portfolios, simulate investment scenarios, analyse market behaviour, test trading strategies, track performance over time, explore transaction histories and evaluate investment decisions using structured data — all from one professional-grade workspace.
