Draft:Brian Long

• File:Symbol opinion vote.svg Comment: Well done on creating the draft, and it may potentially meet the relevant requirements (including WP:GNG, WP:ANYBIO) but presently it is not clear that it does.
  As other reviewers have noted, Wikipedia's basic requirement for entry is that the subject is notable. Essentially subjects are presumed notable if they have received significant coverage in multiple published secondary sources that are reliable, intellectually independent of each other, and independent of the subject. To properly create such a draft page, please see the articles ‘Your First Article’, ‘Referencing for Beginners’ and ‘Easier Referencing for Beginners’. In short, "notability" requires reliable sources about the subject, rather than by the subject.
  Please review the number of references for claims made in light of WP:CITEKILL. 3 WP:RSs are ample per statement.
  Also, if you have any connection to the subject, including being the subject, you must declare that on your Talk page (to see instructions on how to do this please click the link). In instances of a conflict of interest, the review of the page needs to be handled with care, mindful of the higher bar set by pages produced in circumstances of such a conflict. Such pages typically may read too much like a promotional CV or advertorial (see WP:PROMO), which Wikipedia is not; and/or contain prose that is not of a standard appropriate for an encyclopaedia (also see WP:PEACOCK and WP:NPV).
  Please familiarise yourself with these pages before amending the draft. If you feel you can meet these requirements, then please make the necessary amendments before resubmitting the page.
  It would help our volunteer reviewers by identifying, on the draft's talk page, the WP:THREE best sources that establish notability of the subject.
  It would also be helpful if you could please identify with specificity, exactly which criteria you believe the page meets (eg "I think the page now meets WP:ANYBIO criteria #3, because XXXXX").
  Once you have implemented these suggestions, you may also wish to leave a note for me on my talk page, including the name of the draft page, and I would be happy to reassess. As I said, I do think this draft has potential so please do persevere. Cabrils (talk) 01:31, 19 December 2025 (UTC)

Brian Long
Born	Dublin, Ireland
Alma mater	Trinity College Dublin
Occupations	Entrepreneur, venture capitalist
Organizations	Parthus Technologies Atlantic Bridge Capital

Brian Long is an Irish-born semiconductor entrepreneur and venture capitalist. He is the founder and former chief executive of Parthus Technologies (now Ceva Inc), a fabless semiconductor design and IP company. In 2000, Parthus carried out a dual flotation on the London Stock Exchange and Nasdaq. Long later co-founded Atlantic Bridge Capital, a venture capital firm investing in semiconductors, AI, and related deep-technology sectors.

Early life and education

Long was born in Dublin, Ireland. He studied electronic engineering at Trinity College Dublin, completing undergraduate and postgraduate degrees in semiconductor microelectronics.

Career

Parthus Technologies

Long founded Parthus Technologies in 1993 as a fabless semiconductor IP company specialising in DSP, wireless and embedded systems. During the late 1990s, the company licensed semiconductor design platforms to manufacturers including Texas Instruments and STMicroelectronics.

Parthus completed a dual listing on the London Stock Exchange and Nasdaq in 2000. Goldman Sachs acted as global coordinator and lead underwriter for the IPO. Media coverage at the time reported that its valuation rose above £2.7 billion during heightened investor interest in semiconductor IP firms.

In 2002, Parthus merged with the DSP licensing division of DSP Group, forming ParthusCeva (later renamed Ceva Inc.).

After leaving Parthus, the Irish Times and other Irish media sources reported that Long and other former Parthus executives began making early-stage tech investments.

GloNav

In 2006, Long co-founded GloNav, a fabless GPS semiconductor company developing single-chip GPS solutions. In December 2007, NXP Semiconductors agreed to acquire the company in a transaction valued at up to US$110 million. The deal closed in early 2008.

Atlantic Bridge Capital

Long co-founded Atlantic Bridge Capital in 2004 or 2005. The firm is a growth-equity technology investor with operations in Europe and the United States. In 2017, the Irish Independent reported investments in Atlantic Bridge by Denis O’Brien and Dermot Desmond. In 2021, the European Investment Fund stated that Atlantic Bridge managed over €1 billion across eight funds.

Acision transaction

In 2007, a consortium led by Atlantic Bridge and Access Industries acquired the telecom-products business of LogicaCMG (later named Acision) for approximately £265 million (approx. €392 million).

Media dispute (2002)

In November 2002, The Sunday Times published an article alleging that Goldman Sachs had provided Brian Long and Peter McManamon with preferential access to shares in Bookham Technology. Goldman Sachs publicly denied the claim. The newspaper later published an apology stating that any suggestion the allocation was a favour to secure future business was unjustified.

Board roles and investments

Long has made investments in and served on the boards of semiconductor and computing companies. Some of his board and advisory involvements include Navitas Semiconductor Corporation, where he is listed as a director, and Sambanova Systems, which lists him as an advisor.

Awards and recognition

Long and his wife were recognised at the 2015 American Ireland Fund gala in San Francisco.

Personal life

Reporting in The Times and Irish Independent have noted property purchases by Long and his family in Monaco, Silicon Valley and Dublin.
