Company profile

researched Aug 2026

Entera provides a software and services platform for single-family residential (SFR) real estate investing, positioning itself as an operating system covering the full residential investment lifecycle. The platform combines proprietary residential data, market signals and pricing models with AI-powered underwriting and decisioning, workflow orchestration for approvals, offers, listings, diligence and transaction management, and transaction infrastructure including brokerage, title coordination, compliance and closing support. It also coordinates third-party service partners such as brokers, inspectors, renovation partners and field teams so that transactions run through a single workflow.

The product is organized around two main motions: acquisition, spanning investment strategy, asset discovery, AI-powered underwriting, diligence, partner coordination and closing; and disposition, spanning asset evaluation, AI-assisted pricing, buyer targeting, offer management, partner coordination and closing. In earlier press coverage, the platform was described as aggregating listing and off-market property data, scoring properties against an investor's stated strategy, and surfacing listing price, comparable prices and rents, estimated repair costs, a recommended initial offer and capitalization rate, with the ability to place an offer in one click or dispatch an Entera evaluator to inspect the property.

Founding story

Co-founders Martin Kay and Robert Salmons met at a children's birthday party in 2009. Kay, who had worked on data mining and analytics in the energy and infrastructure sectors, was drawn to Salmons' description of real estate as a complex, chaotic system; Salmons, a former builder from a family of real estate professionals, saw an opportunity to use data to reduce uncertainty. Within months they built a model to predict which local properties would deliver high returns and appeal to environmentally-minded renters, and, backed by wealthy individual investors, formed Greenlet to buy and operate properties. Kay tested the model bidding on foreclosed homes at the Harris County Courthouse with a million dollars of cashier's checks; acquired properties leased at expected rents with repair costs near forecast, and the pair scaled the investment to $100 million. Recognizing that providing services was easier than raising acquisition funds, they founded Entera in 2017 and sold off most of the Greenlet portfolio.

Business model

Entera sells platform access and associated real-estate execution services to professional residential investors, combining software with offline services such as brokerage, property evaluation, transaction coordination and service-partner orchestration. Earlier descriptions characterized it as a three-sided marketplace connecting enterprise and mid-market investors, sellers and service providers in the single-family residential market.

Traction

The company reports coverage of 34 residential markets, more than 14 million homes underwritten, over 500,000 homes across client portfolios, and support for billions of dollars in residential transaction activity since inception. Earlier material cited more than 15,000 single-family homes transacted, valued at $5 billion, across 29 US markets, and 2019 press coverage reported that Entera's software helped investors buy several thousand homes a year, including hundreds in Houston.

Latest developments

The company reports having raised approximately $60 million from financial and technology investors to build execution infrastructure for single-family residential real estate, operations across 34 markets, and active hiring across offices in Houston and New York.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Entera describes itself as an operating system for a large, fragmented residential real estate market and uses the analogy of a "Bloomberg Terminal of Real Estate." It states that it serves 95% of top investors, covers 34 residential markets, and has underwritten more than 14 million homes, with more than 500,000 homes across client portfolios.

Entera positions itself on the combination of software with real-world execution: proprietary data coverage that it claims exceeds MLS inventory in some markets, AI-based underwriting and pricing, and local execution through brokerage, evaluators and a coordinated service-partner network, allowing investors to move from strategy to closed transaction on one platform. Press coverage highlighted speed as a core advantage, with customers averaging three minutes from listing to offer.

Technology

The platform is built around proprietary residential property data aggregated beyond MLS coverage, AI-driven underwriting, pricing models and asset-level intelligence, and workflow automation that standardizes underwriting, approvals, offers, listings, diligence and transaction management across markets and teams. Algorithms match properties to an investor's stated strategy and incorporate neighborhood attributes — such as nearby amenities, retail brands, demographics, safety and schools — into property scoring.

Go-to-market

Direct enterprise sales via consultative engagement ("speak with an expert") to investors, operators and funds, supported by local market teams and a network of coordinated third-party service providers across covered markets.

Professional and institutional residential real estate participants: real estate operators buying, selling and operating single-family homes across markets; funds transacting at scale; new construction sellers seeking professional residential buyers; and service partners such as brokerage, title, inspection and renovation providers. Press coverage identified large institutional investors, including hedge funds and firms such as Blackstone and American Homes 4 Rent, among the users of its technology.

Geography

Headquartered in Houston, Texas and New York, New York, with employees in 19 states and platform coverage of 34 US residential markets.

History

Following the Greenlet property-investment venture launched after the 2009 housing downturn, Kay and Salmons established Entera in 2017 to offer institutional investors data-driven property identification and offer execution. By 2019 the company was operating from Houston with transaction coordinators conducting on-site inspections and remodel monitoring for institutional clients. Earlier company material cited operations across 29 US markets from offices in New York City and Houston; the company now reports coverage of 34 residential markets, offices in Houston and New York, and employees in 19 states.

Risks & controversies

Press coverage has framed Entera's technology as contributing to institutional investors outcompeting individual entry-level homebuyers for affordable housing, reducing the pool of homes available to owner-occupants; co-founder Robert Salmons was quoted saying "we hope we're very hard to compete against."
