About the Role

Our client, Replo, is building the "world's sell anything platform," enabling entrepreneurs and marketing teams to instantly build, test, and grow online businesses and campaigns.

The company has raised over $8.4 million from investors like Figma, YCombinator, and Vercel, and has achieved Series A/B metrics on a seed-stage cap table.
