Paul McCarthy, CEO

"Barry and CapF9 were instrumental to the seed round and follow-on rounds for SnapFix.  He guided us through the investment process and facilitated many sessions on the priorities, messages and the options, as well as making key investor introductions.  His practical no nonsense advice was very valuable and very much appreciated."


Emmet Savage, CEO

As one of MyWallSt's earliest investors, Barry has been a supporter from the outset. Apart from his wide network, which he extends to his invested companies, he helps founders and their management teams throughout the development of the business. He is mature, experienced, positive and impactful, and I am delighted to have him as a part owner of MyWallSt.

Alvan Hunt, CEO

"I first met Barry at a conference and within two months we were close to finalising a funding round. CapF9 played a pivotal role in this. Barry’s financial background proved to be invaluable in guiding and advising us as a company throughout the fundraising process.  Along with this, Barry has been a huge asset to the company in his role as an observer on the company board. If you are seeking to raise capital and to engage with an experienced investor, I would highly recommend CapF9."

"At Startup Boost we find the best entrepreneurs globally and prepare them for accelerators and raising investment. To achieve this goal, we need to work with great mentors and Barry Brennan is a key lead mentor in making this happen in our program in Ireland and through our mentor network globally.

Richard Stafford, CEO

"When I founded Fettle, I needed extraordinary people around me for advice, mentorship and guidance. Barry and CapF9 immediately built a trust-based value-added relationship with me and were a huge help in advising me through my first outside investment funding round. Securing seed funding while never actually meeting face to face any of stakeholders involved due to the lockdown was certainly a new and daunting experience for me. But Barry's generosity with both his time and his network was a crucial support for me and I would highly recommend Barry and CapF9."

Colm McLoughlin, CCO

"We first met Barry through the Startup Boost Ireland (2020) Program and are delighted we did.  Barry patiently sought to understand our business in a manner that was both curious, and supportive.  During the program we benefited from Barry's wisdom, guidance, and business advice, with lots of astute nudges along the way.  We felt genuinely supported and encouraged by Barry from day one and look forward to further developing the relationship between both our firms.   Life as a start-up founder is much easier with people like Barry on your side."

Jacapo Losso, Director

"We invited Barry to host a workshop for our angel network members on how to value pre-revenue startup businesses and working with him was a great experience.
The workshop was brilliantly delivered, with many hands-on activities and practical advice delivered to the participants. 
We will definitely invite him again to host this as well as other angel investment workshops for our community."

Anthony O'Neill, M.D.

"Our team has worked with Barry for a number of months as we have been preparing an in-house product for commercialisation. We've found Barry's input extremely valuable. Barry has the ability to look at your company and ask the difficult, probing questions prospective investors and clients will ask. His feedback has been both illuminating and constructive. We are in a better position having engaged Barry and I would recommend him to an early stage business seeking guidance."


John Phelan, Director

"Since joining HBAN in 2016, Barry has been one of HBAN's most active investor and syndicate leads. He brings a wealth of start up, financial and strategic experience to his analysis and execution of the investments, is well respected within the start up community and has played a very active role within HBAN and beyond in the growth of the angel investment ecosystem in Ireland."
