FAQ

Can I cancel anytime?+
Yes. Month-to-month. Cancel from your billing page; access continues through the current period.
What does the founding price get me?+
$49/month locked in for 12 months from signup. After that, you renew at whatever the current price is. The founding rate is only offered to the first 100 subscribers; after that, new sign-ups pay $79/month from day one.
What happens if my target company isn't covered?+
Anthropic and OpenAI are live now. Google, Meta, Stripe, and Databricks are queued. Email support to vote for the next company.
How fresh is the data?+
Question banks are refreshed monthly from new candidate reports. Each question shows when it was last reported (e.g., 'Last reported April 2026').
Is this legal? Won't companies be upset?+
The same model as Glassdoor / Levels.fyi / 1point3acres. Candidates own their experiences and can describe them. We anonymize and never name individual interviewers. We honor takedown requests for legitimate concerns.
