Rauch's number-one advice to founders: create many low-friction opportunities for users to give feedback from inside the product, piped directly to where the team lives (e.g. Slack). This tight loop turns product iteration into a constant stream of real user sentiment that competitors without it can't match — especially decisive for AI products whose next model, prompts, fine-tuning, and RAG all improve on captured feedback.
Origin
Rauch drew inspiration from Stripe's in-product feedback button for the early days of Vercel.
Core principles
- 01Feedback must be captured at the moment of the experience, not after
- 02Low friction (a button, a few emojis) beats a formal survey
- 03Route feedback to where the team already works so it enters daily consciousness
- 04AI products compound on feedback: it feeds the next model, prompt, fine-tune, and RAG
How to run it
- 1
Embed a feedback button in the product
Place a slick inline feedback control at the point of use so users can react in the moment.
Pro tip Stripe's version used four emojis to let users say how they felt about the feature right then.
- 2
Pipe it into the team's workspace
Send submissions straight into a channel the team watches (Slack), so reactions stream into daily awareness.
- 3
Feed the loop back into the product
Use captured feedback and thumbs up/down to improve the next model iteration, prompt, fine-tuning set, examples, and RAG.
Pro tip Often the fix is simply telling users they can give that same instruction directly to the AI as a prompt.
In the wild
In Vercel's early days Rauch added a feedback button with a slick inline form and four emojis that fed straight into Slack, letting the team build day in and day out on a live stream of user thoughts — tens to hundreds a day early on.
→ The team was 'streaming users thoughts right into our consciousness,' making each product iteration sharper; with AI products the feedback became a constant stream that is 'hard to compete with.'
Common mistakes
Collecting feedback outside the moment
Detached surveys miss the in-context reaction; feedback captured at the point of use is far richer and more actionable.
Letting feedback pool where no one looks
If submissions don't route to where the team works, they never enter the daily build loop and the advantage is lost.
Is it for you?
Best for
Early-stage founders and AI product teams who need a tight, compounding iteration loop
Not ideal for
Products with no active users or teams unwilling to act on the incoming stream

“my number one guidance or piece of advice I would give to any startup founder was create a lot of opportunities for people to give…”
“There was a feedback button with a very slick inline form with four emojis that would allow you to decide how you were feeling about…”
“And that would go straight into Slack. And we were building day in and day out just like streaming users thoughts right into our consciousness”
