    Question

    Mark Zhang from Citigroup asked for specific details on the allocation of the 2025 go-to-market investments and questioned why the 2025 guidance wasn't more aggressive given the positive demand signals and strategic initiatives.

    CRO and EVP of Operations Johnny Hecker stated that investments are primarily for expanding sales headcount, with the impact expected mainly in 2026 and beyond. He also noted a shift of marketing funds from the SoHo channel to corporate marketing programs. CEO R. Turicchi added that the expense impact will ramp up through 2025, being lowest in Q1 and highest in Q4.
