01 / What I’m building

The work speaks.

Property intelligence / Flagship01

PropData.

Property is local.
The infrastructure is global.

Independent property intelligence from PropTechUSA.ai. Connecting source-native parcels, addresses, titles, transactions, and context so developers and businesses can build on a foundation they understand.

Delivered through APIs, MCP, bulk data, and custom integrations—with provenance, explicit coverage, and honest gaps.

Build on the data layer.

Property lookup, parcel geometry, market intelligence, rent, comps, neighborhood context and more—delivered for software instead of locked inside another dashboard.

Build log.

Recent milestones, in the order they shipped.

  1. Founder site rebuilt around the work.

    justinerickson.co refreshed with a portrait-led hero, the scale proof rail, the PropData network and current priorities.

  2. PropData scale reframed: 400M+ records, 7B+ data points.

    PropTechUSA.ai repositioned around 400M+ property and parcel records and 7B+ normalized data points across seven country-native products.

  3. France and Spain join the network.

    France entered production launch and Spain launch certification, each behind its own coverage-governed country contract.

    ↗

  4. Estonia goes live.

    National cadastral and address identity with geometry, lifecycle context and source provenance.

    ↗

  5. PropData goes global.

    Great Britain and New Zealand joined the United States as the first international country-native products. Australia followed two days later.

03 / Now

What has my
attention now.

September 2026
01

Taking PropData international.

Expanding country by country while preserving local property identities, sources, coverage rules and semantics.

02

Turning source data into infrastructure.

APIs, OAuth MCP, bulk delivery and custom systems that make fragmented property information usable by modern software.

03

Building products I want to exist.

From property intelligence to sports analytics, I still stay close to the code, the data and the customer problem.

04 / The person behind it

An unconventional
path. A practical
way of building.

I came to technology through business, real estate, and a need to solve the problems in front of me.

01

Sales

Learned how to listen, sell, negotiate, and move toward an outcome.

02

Real estate

Built businesses around messy local information and real operating constraints.

03

AI + code

Used AI to learn software development by building things I actually needed.

04

PropTechUSA.ai

Turned internal tools into independent property intelligence infrastructure.

05

PropData

Built a source-aware data layer designed for software, AI, and enterprise systems.

06

Global

Now expanding country by country without flattening away local property systems.

I’m a self-taught developer with a GED and a background in sales and real estate. AI helped me learn to code. Building and operating the systems taught me what it takes to make them useful.

Today, I stay close to the entire loop: source data, code, infrastructure, product decisions and customer conversations. That proximity is a feature.

The principle is simple: know where the information comes from, be clear about what it can do, and keep building.

Also along the way

Some of the journey
made it into books.

I’ve written about AI-assisted coding, entrepreneurship, and fiction—including The AI Blueprint and Coding with Claude. They’re part of the story, not the center of what I’m building today.

Building something
ambitious?

I’m interested in data, infrastructure, partnerships and difficult problems worth solving. If there’s a practical reason to work together, I want to hear it.
