A custom ROI calculator web app built for [1] as a sales enablement tool. The project originated from a client request and was completed in approximately one day using AI-assisted development. It represents an early example of Asymmetric's capability to deliver bespoke, high-value interactive tools rapidly.
Client contact Aaron reached out to Sebastian requesting an ROI calculator to support sales presentations, with a longer-term goal of publishing it on the Aviary website. The ask was to build a hidden page or standalone tool to help drive ROI-based conversions.
Sebastian used AI to develop the conceptual framework and calculator categories. Mark then built the full application.
A multi-calculator web app hosted at a dedicated domain (aviary-calculators domain registered by Mark), featuring:
Each calculator accepts user inputs, computes results on demand, and displays output inline.
Built in React. Mark described using a brand/appearance module approach: providing AI with the brand guide, logo assets, and color palette upfront so the entire build stays on-brand. When brand guidance wasn't explicit, the AI defaulted to its own choices — a known limitation to address in future builds.
This project was highlighted in the [2] as a proof point for Asymmetric's differentiated AI-driven service capability:
"How many marketing agencies are going to puke out a calculator like this in one day? So I think that there's some opportunity with that stuff." — Mark Hope
