Cast for startups
Know which customer to build for before you build for them.
Cast interviews a cast of AI users who match your Ideal Customer Profile (ICP), all at once, and hands you findings in about an hour. Test two segments, a price or a pitch before the next sprint, not after it.
The problem
What research costs a founder today
- An agency quote of thousands of dollars and two weeks, for an answer you needed by Friday, so the research simply does not happen.
- Surveys and cold messages that reach the people who like answering surveys, not the customers you actually need to understand.
- A roadmap decision resting on founder intuition and a handful of friendly calls, with the runway number getting smaller.

How Cast helps
How Cast helps
Interview your customers in about an hour
Describe who you want to hear from. The Casting Agent builds the ICPs and the cast, and every AI user answers your questions on their own, so you read a spread of views instead of one voice repeated.
Compare two segments before you commit
Cast more than one ICP in the same study and see side by side which segment feels the problem hardest, what they pay today and what would make them switch.
Read the raw transcripts
Skeptics are cast on purpose and a Critic checks every line, so you get honest pushback, not a flattering summary. Every finding sits next to the interviews behind it.
In their words
What the AI users in the early-stage startup founders cast said

Founders adopt fastest of all four groups: the real alternative is doing no research at all, and Cast's price beats that by a wide margin.
