Because we don’t represent a project – we represent **you**.
Our vision is simple: to enable private individuals to purchase an apartment under developer-level conditions.
We are Chaim and Gabriel, two real estate professionals with a strong background in brokerage, development, and investments, who decided to take all our knowledge, experience, and connections – and make them accessible to groups of buyers and investors, both in Israel and abroad.
Instead of “marketing” an existing project to you, we first form a group – and only then set out to find the most suitable opportunity.
This is the most correct, transparent, and rewarding way to enter the real estate market.
I began my journey right after the army, as a broker at RE/MAX Jerusalem. Since then, I have guided dozens of residential and investment deals, working both with local buyers and with American clients. My extensive experience also includes activity in the U.S. market – handling major commercial and industrial building transactions in Texas, Ohio, Florida, Indiana, and more. I am a true believer in the potential of Israeli real estate and view the value of our land as a national asset that develops and appreciates over the years.
I began my journey in brokerage at RE/MAX, where I specialized in high-demand areas of Jerusalem and was selected for the company’s Gold Club. Later on, I deepened my knowledge in the field of development through both studies and hands-on experience – including leading a group of more than 120 buyers in a complex residential project in Efrat. I founded GroupBuy Investments with the goal of making the world of development accessible to private buyers – with an emphasis on personal service, complete transparency, and precise management of every stage in the process.











The solution for investors and buyers seeking a real advantage




Don’t just join a project – join a new way of thinking.
When group power meets entrepreneurial thinking
GroupBuy Investments was founded on a simple yet powerful understanding – that a group of buyers has the ability to change the rules of the game.
Instead of chasing after open projects or paying full price without bargaining power, we build smart groups of buyers or investors, creating real opportunities for them to purchase a new apartment – under conditions usually reserved only for developers.
The company was founded by Chaim Kasselman and Gabriel Shikman, real estate professionals with extensive experience in Israel and abroad, who bring with them a clear vision:
To transform the way private individuals purchase real estate – into a smarter, more organized process with genuine added value.
No. We don’t establish the project from scratch – instead, we identify an existing project at an early stage, approach it with a cohesive group, and secure preferred terms with the developer. This is different from the traditional method, as the risk is lower and the process is faster and clearer.
An individual buyer does not get the same access or terms as a group. Developers usually don’t open early sales to the public, but when we come with a group – we have something to offer, and that’s what enables us to secure prices and conditions that aren’t yet available on the market.
The initial consultation is free of charge. If we find an opportunity that suits you and you decide to join, we will charge a guidance fee according to the agreement – with complete transparency.
Absolutely. Even if you’re not an investor – but simply want to buy an apartment to live in – you can still enjoy all the benefits of group purchasing: a better price, convenient payment terms, and a high-quality apartment at an early stage of the project.
We know that buying an apartment is a big decision – especially when it comes to an investment. That’s why at GroupBuy Investments, we put you at the center, not the project.
If you want to feel confident, understand exactly what’s happening at every stage, and purchase more wisely through a proven model – we invite you to talk with us. No commitment, no pressure – just an open conversation with professionals who understand you and want to help.
Because great deals begin with trust.
