The Liverpool embassy in London has secured further private sector sponsorship guaranteeing its future until July.
The latest businesses who have pledged their support are Ernst & Young, Sutcliffe, NSG UK, Castlewood Property Management and Merepark.
Max Steinberg, chief executive of Liverpool Vision, which is delivering the embassy along with Downtown Liverpool in Business and the council, said: "During its first two months of operation the Embassy has been able to engage with a number of high profile individuals from London, including investment advisors, managers of investment funds and senior MPs."
Since opening in January in London's financial district, the embassy has hosted more than 40 meetings to raise the profile of Liverpool in London and potentially leading to significant investment for the city.
The Embassy is an initiative by business leaders, politicians and public sector organisations to promote the city as a business friendly environment for investment.
Cllr Joe Anderson, leader of Liverpool City Council, said: "The Embassy has been all we could have hoped for, it's essentially about putting Liverpool on the map in London and we've attracted a lot of interest as a place to invest and do business. Some of the meetings that have been held at the embassy could lead to some exciting developments, creating jobs and regeneration.
"Our team is working hard to ensure the right meetings continue to be set up with the right people and I am confident that this hard work will inevitably bring dividends to the city. We've made important contacts with high net individuals in the Middle East and China, which could lead to some exciting developments in Liverpool.
"We also have a number of significant events in the pipeline, for example we are meeting with Grosvenor and some of the UK's major investment banks at the Embassy later in the week, while significant events for the creative and green industries are being held during the coming months."
The Embassy is based at New Broad Street House close to Liverpool Street.
