Silver Lake Partners, the multi-billion dollar tech-focused investment firm, is adding a longterm hedge fund backed by Abu Dhabi’s sovereign wealth fund, Mubadala, to its array of investment vehicles to finance technology companies.

The move into multi-strategy investing represents the diversification of financing vehicles that companies have at their disposal and gives the private equity firm the tools it needs to compete in a world awash with capital and new ways for companies to access public market financing.

It’s probably not a coincidence that the public-private, long-only, investment structure is happening as more tech companies are eschewing later stage financing to find cash on public markets through things like special purpose acquisition companies (SPACS).

According to a statement from the firm, the new strategy has a 25-year deployment life cycle and can be invested across structures, geographies and industries. The agreement makes the two financial entities a couple that will really span time together.

In addition to the new strategy, Silver Lake’s partnership has a new minority shareholder in the Abu Dhabi-backed sovereign wealth fund. Mubadala took a minority stake in the firm by buying up half of the 10% chunk of the firm that Silver Lake’s partners sold to Dyal Capital Partners, a subsidiary of Neuberger Berman.

“Silver Lake is a top performer for Dyal, having innovated, evolved and expanded to prudently grow its assets under management from $23 billion when we first acquired our stake to more than $60 billion today,” said Michael Rees, Managing Director and Head of Dyal Capital Partners, in a statement. “This transaction with Mubadala and their commitment to Silver Lake’s new long-term capital vehicle is a strong endorsement of Silver Lake’s differentiated, global capabilities and underscores our conviction in the ability to generate compelling returns
