A $100m Series B startup is trialling the LSE’s new private market platform to explore alternative liquidity options
Executive summary: A startup that has raised a $100 million Series B round said it will test the London Stock Exchange’s newly created private market platform. The trial highlights demand for alternative liquidity solutions for late‑stage ventures and could affect how growth‑stage companies raise capital.
Who is involved: The unnamed $100m Series B startup, the London Stock Exchange (LSE), and prospective investors using the private market.
Likely next (inference): The startup will run a pilot on the LSE private market, with results informing wider adoption by other late‑stage firms.
The announcement shows that a well‑funded late‑stage startup is testing the London Stock Exchange’s recently launched private market venue. This move reflects growing interest among growth‑stage companies in accessing liquidity outside traditional public listings or secondary sales. If the pilot succeeds, it could signal broader adoption of the LSE’s private market by similar ventures and influence how later‑stage financing is structured in Europe.
