Ehsan's Growth Commentary

After working with 40+ E-commerce companies, the pattern is clear: Marketplace Growth at the Series B stage requires systematic processes. The teams that win start smaller than they think they should and iterate 3x faster than their competitors.

With 30-80 people and $1.5-5M budget, focus Marketplace Growth efforts on the single highest-ROI activity. Do not spread thin across multiple sub-channels. Validate one approach before adding another.
