Kohn - Software Builder & Operator, Custom Development & Data Products
Builder-operator out of Ohio. I design, build, and run my own software businesses, including a five-brand data network, and take on select client work.
Recent builds: LeadLoom, Call Center, DONOS, VanTracker
The Data Network
Five live storefronts, one engine, zero employees. Pick a geography, build a list, pay, and the CSV is in your inbox before you close the tab. Every record is sold once and never resold.
FlagshipLeadLoom
Exclusive turning-65 Medicare lead data. Agents pick a county and a birthday cohort, check out, and their list downloads in seconds.

VoterVault
Verified voter data for campaigns. Build a county voter list, see live counts, and download it instantly.

Explorer
An interactive household data map. Zoom from state to county to street and see the market before you buy it.
Under the hood
Five storefronts host-routed off one deployment. Stripe checkout with idempotent webhook fulfillment, record-level sold-once fingerprinting, programmatic SEO that AI assistants actually cite, and a self-healing enrichment pipeline that grows inventory while I sleep. Every piece self-hosted and owned end to end.

Beyond my own products
Most of my time goes into systems I own and operate. I still take on a handful of client projects a year: websites, dashboards, automations, and data pipelines. If it lives in code, I can build it.
