In the latest comparison between American and European founders, OpenAI’s startup boss admitted that the Americans are “almost shameless” when it comes to making demands and giving feedback to the AI giant.

Laura Modiano, who heads up OpenAI’s startups division in EMEA, drew a comparison between American and European founders based on her extensive work with founders across both regions and rolling out AI features.

“So feedback is extremely important. We’re moving at lightning speed. It has to represent your voice and I see American founders being extremely good, almost shameless, and coming in and saying: ‘We need this. You need to get better at that. You need to improve that. You need this new feature,’” Modiano said during a fireside chat at the Sifted Summit on Wednesday. “If founders don’t tell us, we don’t always know.”

She called on European founders to be much more vocal — or risk missing out on big opportunities.

“Please, please, please, if you’re using OpenAI ... you should always tell us what you think about it, what is working, what isn’t and how we can do better.”
