The European venture of Kansas City-based electronic communications network BATS Trading now has a CEO and COO--Mark Hemsley and Paul O'Donnell, respectively. The London-based platform, which is expected to launch later this year, was announced on March 31. Before founding London corporate advisory business Belvedere Hill, Hemsley spent four years at Euronext.liffe, most recently as managing director and chief information officer in its market solutions group, and has filled various roles, including managing director of global technology, COO and CIO, in Deutsche Bank's global corporates and institutions division. O'Donnell is a 14-year veteran of Morgan Stanley, holding senior information technology and institutional equities positions in Japan and the U.S.

"We're very excited to bring Mark and Paul aboard and are confident that their skills and experience will lead BATS to great success in Europe," said Joe Ratterman, chief executive of BATS. "We are a technology company at our core, and both Mark and Paul fit the BATS executive profile of high-caliber, energetic leaders with a hands-on technology background." Hemsley said that he was "excited to take a pioneering role with a company which has had a tremendous impact on the U.S. market in such a brief period of time." Also citing BATS' impact on equities in the U.S., O'Donnell said that he was looking forward to "partnering with Morgan Stanley and the broker-dealer community to produce similar results abroad."


SWX Europe has named as chief operating officer Mark Ryland, most recently global head of equities information technology at HSBC. Ryland, who was previously global co-head of cash equity systems renovation and has held senior positions at Donaldson, Lufkin & Jenrette--purchased by Credit Suisse in 2001--and UBS, "brings the talent, knowledge and strategic insight to strengthen our business and immediately contribute to our future success," said SWX Europe CEO Lee Hodgkinson. Initially, Ryland will focus on bolstering the exchange's technology platform and the launch of a non-displayed block-trading service, in partnership with Nyfix's Euro Millennium multilateral trading facility, for Swiss blue chips, expected to go live in the second or third quarter. SWX Europe, formerly virt-x, was renamed last month, following the January merger of parent SWX Group and Telekurs Group.


Lexington, Mass.-based complex event processing (CEP) technology provider StreamBase Systems has brought on Mark Palmer as president and COO. As an executive at Progress Software Corp., Palmer led the 2005 acquisition of CEP developer Apama and then served as general manager for the business. StreamBase CEO Chris Riley, noting the January addition of Colin Clark, former CTO of Kaskad Technology, said that "these are two outstanding additions to an already great team and together we will be setting the pace in the industry for delivering tremendous value to CEP customers everywhere." Palmer, who said that he has "admired StreamBase as a technology leader and the vision that StreamBase founder Dr. Michael Stonebraker set for this new computing model," has been director of product management at Iona Technologies and CTO and co-founder of YouthStream Media Networks.


Richard Balarkas, formerly global head of sales in Credit Suisse Advanced Execution Services' brokerage division, has joined New York-based agency brokerage Instinet's European subsidiary as president and CEO. Instinet Europe chairman Tony Mackay is handing over his day-to-day duties at the subsidiary to focus on his role as chief executive of Chi-X Global, which operates trading platforms in Europe and Canada, with another expected soon to open in Australia. Balarkas, who will report to Fumiki Kondo, co-CEO of Instinet, and Mackay, said that "the combination of Instinet's unconflicted agency model, global reach and continued commitment to the evolution of more efficient market structures and advanced equity trading tools make us uniquely positioned to meet the needs of our clients."
