Osttra Lifts Four from LSEG

Months after it was acquired by KKR, and weeks after six banks invested in the business, Osttra has made four hires from LSEG’s post-trade business as part of its work to extend its post-trade operations.
Nathan Ondyak joins as chief commercial officer, Peter Altero as chief business development officer, Chris Licini as buy-side strategic relationship manager, and Christian Kjaeldgaard as product design director. All but Licini previously worked at Markit, one of the foundational businesses of Osttra.
All four were members of the LSEG Post Trade team, playing roles in the development of TradeAgent, SwapAgent, SwapClear and LSEG’s broader post-trade services offering. The firm says the hires are “an important strategic step” and demonstrates Osttra’s commitment under new ownership to continued investment in its businesses.
Ondyak spent over 14 years at LSEG, where he led the expansion of its post-trade capabilities and most recently served as the CEO of LSEG Post Trade Services (TradeAgent) and SwapAgent. Prior to LSEG, he held senior product and sales management positions at Markit.
Altero returns to Osttra from LSEG, where he spent three years as North America head of TradeAgent, SwapAgent and Quantile, responsible for advancing LCH’s post-trade operations outside of its core clearing business. Also returning is Kjaeldgaard, who developed post-trade strategy and solutions across the SwapAgent offering at LSEG, having previously played a role in the evolution of MarkitWire in the product management team at Markit.
Licini has held strategic customer relationship roles at LSEG for more than 14 years, with a particular focus on the buy-side community.
“Nathan, Peter, Chris, and Christian bring deep expertise and proven track records of innovation and collaboration across our industry,” say Guy Rowcliffe and John Stewart, co-CEOs of Osttra in a statement. “This perfectly complements the in-house expertise we already have at Osttra. Their appointments will significantly accelerate our ambition to transform post-trade this year and beyond, turning shared infrastructure into shared benefit.”
