Our Firm


Tuan Palmer

Founding Partner

Vetting Promising Startups

Tuan has over twenty years of experience during which he built his competencies in five critical pillars of the financial sector: stock broker (Solomon Smith Barney, retail finance); investment banking (Montgomery Securities; underwriter, research analyst); venture capital (Newbury Ventures, private sector research analyst); hedge fund (Stryker Capital Management, general partner and money manager, public markets); partner, (New York Life, tax planning and financial portfolio strategist).

Given his extensive experience and expertise in all aspects of the financial sector, Tuan founded ATZ on the idea that the investor experience should be individualized.  The opportunities presented to investors should consider factors such as risk tolerance, sector preferences and desired time for investment exits rather than relying on portfolio managers choices encompassing all investors in a fund.  Tuan brings extensive investment expertise to the ATZ team with his keen sense for vetting prospective business opportunities.
