Mercury is a US-based banking-for-startups product that's become popular with Indian founders who've incorporated Delaware C Corps. If you've heard Indian SaaS founders mention Mercury, this guide explains what it is, when Indian founders actually need it, and what alternatives exist for founders who don't have (or don't want) a US entity.
What Mercury Actually Is
Mercury is a US fintech banking product built on partner bank infrastructure (Choice Financial Group and Evolve Bank & Trust). It offers:
- US business checking and savings accounts
- Visa debit card for US business spending
- API access for banking automation
- Mercury Raise: startup investor network
- Venture debt (Mercury Venture Debt) for qualifying startups
- Multi-entity management Mercury is not a payment gateway. Mercury is a business bank account for your US entity. It doesn't process payments from your customers.
Mercury requires a US business entity. You must have a Delaware C Corp, Delaware LLC, or other US business entity to open a Mercury account. Indian businesses cannot open Mercury accounts directly.
When Indian Founders Need Mercury
Indian founders use Mercury when they:
- Have incorporated a Delaware C Corp for VC fundraising or US operations. Mercury is the banking layer for that US entity.
- Receive Stripe payouts via their US entity. Stripe settles to a US bank account. Mercury is where Stripe settles.
- Pay US contractors, employees, or vendors from their US entity. Mercury's checking account handles US-side disbursements.
- Need US-side banking for Stripe Atlas founders. Stripe Atlas + Mercury is a common stack for Indian founders setting up US entities. If you don't have a US entity, you don't need Mercury — and can't use it. Many Indian founders think about Mercury when what they actually need is better cross-border payment infrastructure for their Indian entity.
The Alternative: India-Native Payment Infrastructure Without a US Entity
For Indian founders who don't have (and don't want) a US entity, Playto Pay provides the international payment collection that eliminates the need for a US entity + Mercury stack for most use cases:
| What you'd do with US LLC + Mercury + Stripe | What you do with Playto Pay |
|---|---|
| Incorporate Delaware LLC ($500-2K) | No offshore entity needed |
| Open Mercury bank account (US entity required) | Use your existing Indian bank account |
| Connect Stripe to Mercury | Connect Playto Pay to Indian bank |
| Accept international card payments via Stripe | Accept international card payments at 4% flat |
| Transfer USD from Mercury to India via Wise (~0.5%) | INR direct daily, zero forex markup |
| Request FIRA from bank manually | FIRA auto-generated per transaction |
| Pay $1,000-3,000/year US LLC compliance | ₹0 ongoing |
For Indian founders below $10K monthly international revenue: Playto Pay eliminates the need for US LLC + Mercury + Stripe setup. Significant cost and operational savings.
Mercury Alternatives: If You Need US Banking
For Indian founders who do have a US entity and need US-side banking:
Mercury: Free for standard features. Strong developer tools. Popular with YC/VC-backed startups.
Brex: Business banking + corporate cards. Better expense management. Requires US entity.
Relay: Banking-focused (less startup features than Mercury). Multi-account structure useful for separating expenses.
Wise Business (USD account): For founders who want a USD account without a full US business bank relationship. Easier to open for non-US founders in some cases. Less functionality than Mercury.
