Hawaii Information Service

What Hawaii Information Service does

Hawaii Information Service, operating as MLS Hawaii, Inc., is a Honolulu-based real estate technology and property data company founded in 1985 (originally as the Neighbor Island MLS). It serves as the primary Multiple Listing Service provider for Kauai and Hawaii Island and operates a statewide TMK (Tax Map Key) public records service covering nearly 600,000 Hawaii properties with over 300 data fields per parcel. The company is a privately held Hawaii corporation operating as a wholly-owned subsidiary of Hawaii Island Realtors and the Kauai Board of Realtors, employs 11-50 people, and is led by CEO & President Faith Geronimo (appointed 2013) alongside COO Colleen Yasuhara (promoted 2017). HIS has held RESO Standards Certification since 2021 and has been named to Hawaii Business Magazine's Best Places to Work for 10 consecutive years as of 2025.

The core technology is HIMLS, a ground-up custom MLS platform launched in February 2024, built with RESO Web API compliance and deep integration to the company's TMK public records database and statewide GIS data. The product portfolio includes TMK Public Records, TMK API Services, RESO Web API IDX/VOW/BOF/BBO data feeds, custom property data reports, TMK Maps (GIS), Condo Guide, website design services (Smart Start and Premier Custom), the Stories digital marketing tool, and the AlohaLiving.com consumer-facing real estate portal, with mobile apps for iOS and Android. Third-party integrations include ShowingTime for showing scheduling, Cloud CMA for market analyses, Realtors Property Resource (RPR), and ZipForm for contract management.

HIS generates revenue primarily through subscription-based MLS memberships for realtors on Kauai and Hawaii Island, plus subscription access to TMK Public Records and ancillary services (IDX/VOW feeds, websites, advertising, custom reports, API access). Distribution is direct sales-led, with a dedicated sales team and phone/email channels segmented by function. The customer base spans real estate brokers and agents (primary), plus financial and legal services, insurance, appraisal, property management, real estate developers, and investigative journalists that subscribe to TMK data. Marketing relies on owned digital properties (hawaiiinformation.com and AlohaLiving.com), direct sales outreach, customer testimonials, and earned media coverage in Hawaii Business Magazine, Pacific Business News, KHON2, and KITV.
