SAAS · SAMPLE CASE STUDY

From a property spreadsheet to an $18k/month subscription product

THE APPROACH

Three moves that changed the work.

  1. 01Shape the product

    We cut the idea down to one paid workflow: property lookups with saved watchlists.

  2. 02Build the data core

    A nightly pipeline and valuation model replaced the hand-updated spreadsheet.

  3. 03Launch and iterate

    Accounts, billing and dashboards shipped in week 12, then improved every two weeks.

RESULTS
