Fungibility LLC designs, builds, and operates a small portfolio of web applications. Our customers are van builders, online resellers, and real estate agents: independent operators who need one specific tool to work properly, without an enterprise contract attached to it.
Each one began as a tool we needed and could not buy. All three are live, actively maintained, and supported directly by the people who wrote them.
A 3D layout planner for van, box truck, and skoolie conversions. Builders place real components to scale inside their actual vehicle dimensions, then generate a parts list, weight totals, and cost estimates before cutting a single board. Free to use, with a paid tier for payload math and print-ready plans.
vanometry.comA real-time listing scanner for Etsy resellers. Powerbuyer surfaces new listings within a minute of posting, with keyword filtering, seller blocking, and Telegram alerts, so buyers see inventory before it moves. Built entirely on Etsy's official API.
powerbuyerapp.comAutomated photo editing for real estate listings. Agents upload phone photos and get listing-ready images in roughly forty-five seconds each, covering window replacement, exterior cleanup, twilight conversion, and virtual staging. Priced per image, with no subscription and no minimum order.
biziedit.comEvery product listed here belongs to the company. We are not an agency and do not take contract work, which means the roadmap answers to the people using the software rather than to whoever is paying for the sprint.
Each product solves one problem completely instead of five partially. Staying narrow keeps the software fast, keeps it cheap to run, and keeps it possible for a small team to support properly.
Email reaches the person who wrote the code. There is no tier system, no ticket queue, and no outsourced first line.
Fungibility LLC was founded in 2021 by Michael Macintire. The company started in e-commerce, where it sourced, warehoused, and distributed consumer products across online marketplaces. It moved into software after several years of building internal tools to run that operation, and now develops and operates its own web applications full time.
Michael worked as a real estate photographer in St. Augustine before founding the company, which is where BiziEdit came from: photo editing turnaround was the bottleneck on every listing, and nothing available solved it at the speed or the price agents actually needed.
