o2h Ventures Participates in Oversubscribed Seed Round to Advance CamGene Therapeutics’ RNA-Based Medicines
o2h Ventures Participates in Oversubscribed Seed Round to Advance CamGene Therapeutics’ RNA-Based Medicines
Nov 3 2025

Cambridge, UK 

CamGene Therapeutics, a pioneering biotech company developing RNA-based treatments for hearing loss, has successfully closed an oversubscribed seed funding round. The round was led by UKI2S and joined by Eos Advisory, Cambridge Enterprise Ventures, HexTwo, LongRiver Investments, Parkwalk Advisors, with o2h Ventures participating as an investor.

Hearing loss affects over 1.5 billion people worldwide, with more than 430 million experiencing moderate-to-severe impairment. Current solutions such as hearing aids and cochlear implants manage symptoms but cannot restore natural hearing. CamGene is pioneering RNA-based therapeutics that target the underlying cellular dysfunction, offering the potential to halt progression and restore hearing function. This could be a transformative advance for millions of patients.

From the earliest stages, o2h Ventures has supported CamGene through its integrated biotech ecosystem by providing co-working lab and office space at Hauxton House, hands-on scientific input via o2h Discovery, early-stage capital funding through the o2h Human Health SEIS Fund, and ongoing board-level mentorship and strategic support, helping the team focus on innovation and rapid development.

CamGene combines world-leading LNP-mRNA technology with clinical expertise from ENT surgeon-scientists at the University of Cambridge. The newly raised funds will accelerate preclinical development, refine the proprietary RNA delivery platform, and support the translation of groundbreaking science into first-in-human therapies. With a high-calibre board and expert advisors, CamGene is well-positioned to transform outcomes for patients with hearing loss.

Sunil Shah, CEO of o2h Ventures, said: 

It’s fantastic to have worked with the founder, Dr Arpan Desai, from idea generation, through active incubation in Hauxton House, Cambridge,  through to now a seed round backed by such great investors. Looking forward to supporting the company through to the clinic. 

Arpan Desai, CEO of CamGene Therapeutics, said: 

The support and mentorship we’ve received from o2h ventures has been instrumental in shaping CamGene’s early journey. Their deep understanding of biotech innovation, combined with the collaborative energy of Hauxton House, has created an environment where ideas flourish and momentum builds. It’s been a pleasure growing our company in such a dynamic and supportive ecosystem

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.
