Dark Funnel

The dark funnel is everywhere a buyer researches, compares, and forms an opinion that never shows up in your analytics — private Slack groups, podcasts, word of mouth, DMs. They arrive "ready to buy" and your attribution model shrugs.

AI assistants are the newest and fastest-growing part of it. A buyer can ask ChatGPT or Claude to compare your category, get a shortlist, and decide who to contact — all before they ever land on your site. In your dashboard it shows up, if at all, as a single anonymous chatgpt.com referral.

Why it matters for the ChatGPT funnel

You can't optimize what you can't see. If the decision is happening inside a chat, then experimenting on your landing page, segmenting your email, and polishing your funnel all miss the moment that actually matters. The dark funnel is exactly why brands feel demand they can't explain — and can't influence.

How drio fits

drio pulls that moment into the light. Because the conversation runs through your app, you can finally see which questions become pipeline, shape the comparison while it's happening, and capture the lead — turning the darkest part of the funnel into the most measurable.
