Rimini Street has appointed two senior executives to its global leadership team, naming Keith Costello as chief operating officer (COO) and Alexander Guasch as chief delivery officer (CDO).
The company said the appointments are intended to support growth and delivery execution as it scales globally. Costello previously served as president, enterprise applications and technology at DXC Technology and as global managing partner for IBM’s SAP business unit. Guasch has held senior executive roles at HPE, IBM, VMware and Cognizant, and has also held leadership positions at Effectual and Optiv.
Rimini Street said Costello will be responsible for product strategy and for overseeing professional services sales and other global business operations, which it said will transition from president and CEO Seth Ravin.
Guasch will oversee end-to-end development and delivery of the company’s products and services worldwide, with responsibility for service delivery and operational execution, according to Rimini Street.
In a statement, Costello said: “It’s an exciting time at Rimini Street. The company has successfully sold billions of dollars of services and built a differentiated offering that helps clients unlock more value from their mission-critical enterprise systems while gaining greater control over their technology roadmaps. I’m looking forward to working with the global team to scale operations, strengthen execution and support the company’s continued growth worldwide.”
Guasch said: “Client success starts with consistent, high-quality delivery, especially for the mission-critical systems that keep global organisations and government clients running smoothly. I’m pleased to join Rimini Street and lead an organisation that has a storied reputation as one of the best enterprise software and technology engineering teams in the world, delivering 24/7/365 service globally with an average two-minute response time and client satisfaction ratings of 4.9 out of 5.0.”
Rimini Street said it is focused on executing its operating plan to accelerate revenue growth and increase profitability, and described the expanded leadership roles as strengthening execution and scaling global operations.
Ravin said: “Keith and Alex bring the global operating experience, execution discipline and client-first leadership to scale our organisation with speed and quality. Keith and Alex understand what it takes to run and grow complex technology organisations and deliver extraordinary client outcomes. They are welcome additions to our leadership team as we continue helping clients use technology to lower their total operating costs, improve profitability and enhance competitive advantage.”
