On March 27, 2025, Siderofsky Strategic Advisors LLC announced a noteworthy development: Stephen Siderow, the company's Founder and Managing Principal, was appointed to the Advisory Board of Allposit, Inc. This appointment is significant, as Allposit is known for offering integrated digital solutions tailored for the wealth management industry.

We are confident that he will contribute greatly to our efforts to build an innovative, data-driven and AI-powered investment aggregation and analytic platform."

Central to this innovation is their unique "dashboard of dashboards" app, which offers comprehensive real-time reporting, analytics, and scenario analysis, empowering users to make informed investment decisions.

The app leverages Allposit's proprietary Smart Transactions data standard, facilitating an integrated account of the entire investment transaction lifecycle. This ensures that the complexities of various ownership structures and asset types are effectively managed, thus simplifying the client balance sheet and cash flow reporting process for investment advisors.

His extensive background as both a founder and a consultant positions him as an essential asset in navigating the challenges faced by rapidly growing firms. His previous role at BlueMountain Capital Management saw him orchestrate significant transactions, including minority interest sales and the sale of the entire firm to Assured Guaranty.

In addition to his professional contributions, Siderow is an active philanthropist and holds positions on several nonprofit boards. His commitment to social responsibility is reflected in his involvement with organizations that focus on leadership development and healthcare innovation.
