Tech platform provider Riskalyze says it has struck an enterprise-level deal with HighTower, an  RIA network with 99 advisory businesses and about $70 billion in total client assets. With the partnership, HighTower advisors will have access to client engagement, data analytics and trading-automation tools.

"We are honored that HighTower has chosen Riskalyze and are excited to partner with their advisors," said Riskalyze CEO Aaron Klein, in a statement. "Our mission to empower the world to invest fearlessly continues to grow thanks to incredible firms like HighTower who align with our priorities and vision."

The news comes about a month after Riskalyze announced a similar deal with Waddell & Reed, a broker-dealer with roughly $57.4 billion in assets under administration as of June 30 and 1,347 advisors and associates.

HighTower says it chose Riskalyze to help its advisors align portfolios and clients' risk tolerance and to boost advisors' prospecting abilities. With Riskalyze's trading-automation solution, Autopilot, advisors also can "make intelligent fiduciary decisions through technology," the two firms say.

"We have been eager to partner with Riskalyze and provide their offerings to our advisors, to better equip their decision-making, support document alignment, fiduciary duty to clients and more," according to HighTower Chief Risk Officer Jared Schwartz.

Chicago-based HighTower, led by Bob Oros, is backed by the private equity firm Thomas H. Lee Partners of Boston.
