OpenAI is expanding its marketing efforts for ChatGPT by building an in-house platform. They are hiring a Growth Paid Marketing Platform Engineer to develop tools for ad platform integration and campaign management. This signifies OpenAI's plans for an internal marketing platform within ChatGPT, aligning with broader growth initiatives. The platform will manage campaigns, measure attribution, and optimize ad spending without relying on external agencies. This move could potentially lead to a product allowing other brands to run campaigns through ChatGPT. Analysts suggest this shift reflects OpenAI's for-profit pivot and focus on revenue generation. CEO Sam Altman now views ads differently after experiencing the value of Instagram ads. He believes there's potential for a beneficial ad product for ChatGPT users. OpenAI's revenue projections indicate a focus on monetizing free users. The company aims to create an ad experience that is a net positive for its users.
