Boston-based Memcyco provides a day-zero digital risk-protection platform that embeds covert sensors across customer-facing web assets to detect and disrupt brand-impersonation and ATO attacks before credentials are stolen. The agentless technology infiltrates the entire attack timeline, giving enterprises real-time visibility into both victims and attackers while adding no friction for end users. Demand for the solution has produced a threefold year-over-year increase in annual recurring revenue and tripled the company’s customer base. Operationally, the platform has already blocked more than 3.5 million ATO attempts and catalogued over half a billion device identities, demonstrating meaningful scale. Memcyco claims its preemptive approach reduces fraud losses, strengthens compliance, and delivers rapid ROI. With fresh capital, the company plans to accelerate global expansion, prioritizing high-fraud regions such as Latin America. Including its new Series A, Memcyco has raised a total of $47 million to date.
