About Tides

Blue Background

We seek to invest in public or private equity opportunities that are often esoteric in nature, providing significant value creation through change, entrepreneurial passion and tailored capital solutions. To date, Tides has invested in 5 public opportunities, exiting 4 through M&A, and 3 private companies, all in which Mr. Mackay is very active and sits on the board.
