# Ekphrastic > Ekphrastic is an enterprise value selling platform for creating interactive ROI models, economic impact calculators and financial business cases. It helps B2B revenue teams quantify customer value, build evidence-backed business cases, create interactive buyer experiences and understand buyer engagement. Ekphrastic combines AI-assisted ROI model generation with a visual, no-code modelling environment. Users can generate a structured financial model from plain-English business requirements and then refine its assumptions, inputs, calculations, formulas, outputs and recommendations before publishing. The platform follows the principle: AI-generated foundations. Human refinement. ## Core Platform - [Ekphrastic](https://www.ekphrastic.io/): Overview of Ekphrastic and its approach to interactive ROI modelling, economic impact modelling and value selling. - [Enterprise Value Selling Platform](https://www.ekphrastic.io/platform): Overview of the Ekphrastic value selling platform, including AI-powered ROI modelling, financial business cases, buyer experiences, supporting evidence and engagement analytics. - [Platform Features](https://www.ekphrastic.io/features): Detailed capabilities for creating, refining, governing, publishing and analysing interactive ROI models. - [Who Ekphrastic Is For](https://www.ekphrastic.io/who-its-for): How sales, sales engineering, value engineering, revenue operations, product marketing, customer success and other B2B revenue teams can use Ekphrastic. - [Frequently Asked Questions](https://www.ekphrastic.io/faqs): Frequently asked questions about Ekphrastic, ROI models, economic impact calculators, publishing, sharing and analytics. ## ROI Modelling Ekphrastic enables organisations to create transparent financial value models with editable assumptions, inputs, formulas and outputs. Models can quantify outcomes including financial savings, productivity improvements, operational benefits, investment requirements, net benefits, ROI and payback periods. Users can create scenarios and adjust assumptions to explore how different business conditions affect the resulting financial case. ## Economic Impact Calculators Ekphrastic supports economic impact calculators that quantify the potential business impact of a product, service or initiative without necessarily requiring investment or pricing information. Economic impact models can be used earlier in a B2B sales process to identify, explore and quantify potential customer value before developing a complete ROI or financial business case. ## AI-Assisted Model Creation Ekphrastic can generate a structured baseline ROI or economic impact model from a plain-English description of a business problem, assumptions and desired outcomes. AI assists with creating the initial model structure, assumptions, inputs, outputs, calculations and business-case content. Generated models remain editable. Users can inspect and refine assumptions, calculations, formulas, outputs, recommendations and presentation before publishing. AI accelerates model creation while users retain control over the resulting financial model. ## Value Selling and Buyer Engagement Ekphrastic is designed to support value-based B2B selling. Revenue teams can use interactive models to explore assumptions and scenarios with buyers rather than relying exclusively on static spreadsheets, PDFs and presentations. Published buyer experiences can combine interactive ROI models, economic impact calculations, financial business cases, recommendations and supporting evidence such as case studies, research, documents, presentations and videos. Buyer engagement analytics help revenue teams understand how shared content and models are being explored. ## Example Models - [AI After-Call Work Savings Calculator](https://www.ekphrastic.io/examples/contact-centre-acw-automatic-summaries-with-ai-economic-impact-calculator): Economic impact model for using AI-generated summaries to reduce contact-centre after-call work. - [LED Lighting Retrofit ROI Calculator](https://www.ekphrastic.io/examples/led-lighting-retrofit-roi-calculator): ROI model covering energy savings, maintenance savings, investment, payback, ROI, total cost of ownership, net present value and CO2 reduction. - [HMO Rental Yield ROI Calculator](https://www.ekphrastic.io/examples/hmo-landlord-yield-roi-calculator): Financial model for analysing HMO property investment performance, rental income, operating costs and investment yield. ## Insights - [ROI Modelling and Revenue Intelligence Insights](https://www.ekphrastic.io/roi-insights): Articles about ROI modelling, economic impact, value selling, business cases, buyer engagement and revenue intelligence. ## Documentation - [Ekphrastic Help Centre](https://ekphrastic-io.gitbook.io/ekphrastic-help-centre/): Product documentation covering creation, configuration, publishing, sharing, buyer engagement and management of Ekphrastic content. ## Key Concepts Ekphrastic is primarily associated with interactive ROI modelling, economic impact modelling, financial business cases, value selling, value engineering, business value modelling, scenario modelling, buyer engagement and AI-assisted financial modelling.
