About

The Housing Agency Marketplace is an always-on eprocurement platform for Housing Agencies, large-to-small, across the United States. 

The company started as the vision of three men with diverse backgrounds: one an entrepreneur and marketer; another with an expertise in information technology; and the third an expert in procurement with special emphasis in HUD and Housing Agency regulations.

The Housing Agency Marketplace is an always-on eprocurement platform for Housing Agencies, large-to-small, across the United States. It serves housing agencies across the country and is still 100% privately owned. We're headquartered in horse country, Lexington, KY with satellite offices in other states.

To this day, all three initial founders are actively involved in the day-to-day operations of the company.

Early growth

In 2002, Larry Hancock, Mike Gifford, and Valerio della Porta started a software company called the Housing Agency Marketplace. Their focus was on helping Buyers (Housing Agencies publishing solicitations) and vendors (who wish to bid on these solicitations) to easily communicate via the internet during and after the bid process.

It gave Housing Agencies, small to large, access to cutting edge technology that could facilitate the procurement process at a fraction of the cost of doing it in house.

In 2004, Procurement Assistance Software and Support, LLC was formed to provide web-based procurement software to public, private, and not-for-profit-organizations across the country.

The Housing Agency Marketplace fell under this umbrella and has grown to become the largest private provider of innovative technology-driven procurement solutions for the housing agency sector.

Planning for the future

2014 led to the creation of the future blueprint and re-branding of the company to International eProcurement LLC.  IE LLC was formed using the same initial core values as in 2002:

  • Customer service w/ integrity
  • Honesty
  • Courtesy
  • Under promise / over deliver
  • Innovation
  • Profitability
Both the Housing Agency Marketplace and the newly formed USA Buyers Marketplace were now under the International eProcurement umbrella. 

The Housing Agency Marketplace now having over 100 clients nationwide and 17,000 vendors using the software. 

With our broader marketing efforts for the Housing Agency Marketplace now in full swing,  the timing is perfect to take USA Buyers Marketplace to the next level. 

Our latest chapter

Expansion is on the horizon! 

We're making dramatic improvements to the Housing Agency Marketplace core software.

The USA Buyers Marketplace is being taken from wireframe to reality as we narrow our focus to public and private sector procurement solutions.
