How do tiers work?
Companies are grouped into tiers by difficulty/prestige. Submitting a higher-tier bank lets you access more banks in return:
Tier 0 — Top quant firms & OpenAI/Anthropic — gets you any bank
Tier 1 — Meta, Stripe, Netflix, etc. — gets you Tier 1+
Tier 2 — Atlassian, Apple, Snap, etc. — gets you Tier 2+
Tier 3 — Adobe, Salesforce, Lyft, etc. — gets you Tier 3+
Tier 4 — Amazon, Tesla, Oracle, etc. — gets you Tier 4+
Tier 5 — All others — gets you Tier 5 only
Frequently Asked Questions
Why can't I see certain banks in the exchange options?
Two possible reasons: 1) Your submitted bank's tier may be lower than the bank you want — you can only trade for banks at the same tier or below yours. 2) We may not have that bank in stock yet. You can always buy a bank directly regardless of your tier.
What determines a company's tier?
Tiers are based on interview difficulty and company prestige. Tier 0 includes top quant firms and frontier AI labs, while higher-numbered tiers include progressively broader sets of companies. This ensures fair trades — a harder-to-get bank earns you access to more options.
Can I buy a bank instead of trading?
Yes! You can purchase any available bank directly on our home page — no trade required, no tier restrictions. Buying is instant.
How long does review take?
Typically 1-2 business days. We check that the questions are genuine, non-trivial, and match the claimed company. You'll receive an email with the download link once approved.
What if my company isn't listed?
Select "Other (not listed)" in the dropdown. Your bank will be treated as Tier 5. If you think it should be in a higher tier, let us know and we'll review the placement.
