In this brief monologue, the speaker (Andrew Gazdecki) explains that the hardest part of building an AI startup is acquiring and retaining users. He notes that user churn spikes dramatically whenever a competitor, such as ChatGPT, releases a new update, causing users to leave within minutes. To combat the difficulty of gaining users, the startup relies heavily on cold email outreach, collecting email addresses and sending repeated messages in hopes of converting recipients into users. The overall message highlights the volatility of the AI market and the reliance on low‑cost, high‑volume outreach to sustain a user base.

Hardest part was getting users because getting and keeping them with the down rate as low as possible is very tough. A new like update from chat GPT and killed myself in a minute. That's the hardest part. So we basically do cold mail because we had, from my perspective, it's like we have varsity mails. So you gather their mails and just keep sending them all emails from them. We're going to get some users.
