The funding will be used to grow headcount from 35 to over 100, accelerating product, engineering, and go-to-market efforts. Since its 2023 founding, Agentio has emphasized feedback-driven optimization to improve campaign performance. A cited example shows a creator partnership with Bilt Rewards arising from the platform, illustrating automatic discovery and activation of brand-creator opportunities.
