PropertyLimBrothers tightens corporate rules after co-founder Melvin Lim’s alleged cheating scandal

The Singapore-based real estate agency, known for its home tour videos on social media, plans to introduce a formal code of conduct that may include guidelines on workplace relationships, professional behaviour and dress standards, according to The Straits Times.

The move aims to reinforce accountability and foster a safer working environment, PLB co-founder Adrian Lim said.

The firm has also set up a whistle-blowing channel to allow property agents and employees to report concerns anonymously. Serious violations may lead to disciplinary measures, including termination, he added.

PLB came under scrutiny in late January after allegations emerged of an extramarital affair between the firm’s second co-founder and former CEO Melvin Lim, 45, and Grayce Tan, 29, who was then vice-president of strategy.

One of the posts that went viral was a six-minute video that ends with the pair leaving a room together. Adrian said the footage was not recorded at the PLB office.

A screenshot also surfaced of a supposed private WhatsApp message from Melvin to staff, in which he apologized for his “personal mistake and crossed boundaries” and announced that both he and Tan had resigned, according to AsiaOne.

On Jan. 25, both Melvin and Tan stepped down from their posts in the company. Melvin got married at the age of 24, and has four children aged between seven and 20. Tan is also married to someone else.

Adrian said he first became aware of the alleged affair after being alerted to messages and videos circulating among property agents and on online forums such as Reddit. “I came to know when it surfaced online, like everyone else,” he said.

“Once the facts were established, the leadership team aligned quickly on the appropriate course of action. The decision was made within a day and communicated to staff immediately to ensure transparency and business continuity.”

Adrian confirmed that his co-founder had stepped back from daily management about six to seven months before the controversy surfaced.

He added that Melvin had reduced his involvement with PLB to focus on KW Singapore, a franchise of the U.S.-based real estate agency Keller Williams, which he launched in July 2025. KW Singapore operates separately from PLB, he added.

Addressing the fallout, Adrian said three salespeople had left the agency and four clients chose not to proceed with PLB.

He acknowledged that morale among agents initially dipped after the incident, but said management addressed the concerns through “weekly huddle” meetings, internal awards events and Chinese New Year gatherings.

PLB was founded in 2017 by Adrian and Melvin, who first met while working as prison officers.

The firm built a strong online presence through home tour videos and property analyses, many of which prominently featured Melvin.

Adrian also refuted rumors that the company’s money was used to fund a hotpot business co-owned by Melvin and Tan.

“There was an internal review of those claims the moment the incident was surfaced to the management team.”

Looking ahead, the company plans to continue investing in technology and data tools to support both agents and clients. In March, the firm launched a new platform called Property Analysis, which enables users to generate reports on residential properties in Singapore, including transaction histories and pricing data.

“One incident like this cannot define the many good works of many realtors in the industry,” Adrian said.
