o2h ChaiTime Portfolio Pitch Day – Apr 2025 Edition

Live pitches from pioneering biotech companies from o2h Ventures portfolio

About the event

After four successful editions in 2024—where 19 portfolio companies pitched to more than 150 investors—the o2h ChaiTime Portfolio Pitch Day has firmly established itself as a key platform for early-stage biotechs to connect with strategic investors and partners.

On April 2025, we kicked off the new season of ChaiTime at our Cambridge HQ with another exciting afternoon of science, pitching, and networking. This invite-only event combined five dynamic 10-minute pitches from pioneering biotech companies, a keynote session, and plenty of time to spark conversations over Friday drinks. Our global investor community also joined live via Zoom, keeping the energy international.

The April edition continued the ChaiTime tradition of showcasing breakthroughs, creating connections, and shaping the future of healthcare through collaboration and investment.

This edition’s line-up included:

  • Chris Ullman, CEO at Stratosvir

  • Ciara Doran, CEO at Sansanima

  • Mark Treherne, CEO at Revolver Tx

  • Adam Collier, CBO at Spirea
  • Dr Nataly Hastings, CEO at Cellestial Bio

If you would also like to attend the next o2h ChaiTime Portfolio Pitch Day, you can register your interest through the event form, and we’ll make sure you receive all the details once the date is announced.

    Please refer to the relevant fund’s full risk warnings contained in their Information Memorandums.
    Your capital is at risk. Investing in early stage businesses involves risks, including illiquidity, lack of dividends, loss of investment and dilution, and it should be done only as part of a diversified portfolio. o2h Ventures’ funds are targeted exclusively at sophisticated or high net worth investors who understand these risks and make their own investment decisions. Tax relief depends on an individual’s circumstances and may change in the future. In addition, the availability of tax relief depends on the company invested in maintaining its qualifying status. Past performance is not a reliable indicator of future performance. You should not rely on any past performance as a guarantee of future investment performance.
    o2h Ventures Limited is regulated and authorised by the Financial Conduct Authority (FRN 812245). Capital at risk, only suitable for high net worth and sophisticated investors.

    Risk Information

    Due to the potential for losses, the Financial Conduct Authority (FCA) considers this investment to be high risk

    What are the key risks?

    1 – You could lose all the money you invest

    • If the business you invest in fails, you are likely to lose 100% of the money you invest. Most start-up businesses fail.

    2 – You are unlikely to be protected if something goes wrong

    • Protection from the Financial Services Compensation Scheme (FSCS), in relation to claims against failed regulated firms, does not cover poor investment performance. Try the FSCS investment protection checker here. (https://www.fscs.org.uk/check/investment-protection-checker)

    • Protection from the Financial Ombudsman Service (FOS) does not cover poor investment performance. If you have a complaint against an FCA-regulated firm, FOS may be able to consider it. Learn more about FOS protection here. (https://www.financial-ombudsman.org.uk/consumers)

    3 – You won’t get your money back quickly

    • Even if the business you invest in is successful, it may take several years to get your money back. You are unlikely to be able to sell your investment early.

    • The most likely way to get your money back is if the business is bought by another business or lists its shares on an exchange such as the London Stock Exchange. These events are not common.

    • If you are investing in a start-up business, you should not expect to get your money back through dividends. Start-up businesses rarely pay these.

    4 – Don’t put all your eggs in one basket

    • Putting all your money into a single business or type of investment for example, is risky. Spreading your money across different investments makes you less dependent on any one to do well.

    • A good rule of thumb is not to invest more than 10% of your money in high-risk investments (https://www.fca.org.uk/investsmart/5-questions-ask-you-invest)

    5 – The value of your investment can be reduced

    • The percentage of the business that you own will decrease if the business issues more shares. This could mean that the value of your investment reduces, depending on how much the business grows. Most start-up businesses issue multiple rounds of shares.

    • These new shares could have addition rights that your shares don’t have, such as the right to receive a fixed dividend, which could further reduce your chances of getting a return on your investment.
