Ponzi set up a larger office, this time in the Niles Building on School Street. Word spread, and investments increased rapidly. Ponzi hired agents and paid them generous commissions. Between February and March 1920, the total amount invested had risen from $5,000 to $25,000 ($ to $ in , respectively).

As long as money kept flowing in, existing investors could be paid with the new money. This was the only method Ponzi had to continue providing returns to existing investors, as he made no effort to generate legitimate profits.

In its heyday, nearly 75% of Boston's police force had invested in the scheme. Ponzi's investors even included those closest to him, like his chauffeur John Collins and his own brother-in-law.
