# Firms

<figure><img src="/files/7FOTs6P1q1BaPBuxeqME" alt=""><figcaption></figcaption></figure>

Firms are the foundation of Cash City. Each firm starts with 8 desk slots for Interns. Buying a Firm is the only action in the game that costs SOL — everything else runs on $CASH.

## Buying a Firm

Each firm costs **1 SOL** and comes with:

* 8 desk slots (Level 1)
* 1 free Intern pack

You can own up to **15 Firms** per wallet. More Firms means more desks, more Interns, and a larger share of the network's emissions.

***

## Upgrading

Firms can be upgraded from Level 1 through Level 6. Each upgrade adds 2 additional desk slots, giving you more capacity to seat Interns, increase your Efficiency, and generate more $CASH. Upgrading your Firm has a 24-hour cooldown before you can upgrade again.

Upgrading a firm from Level 1 to Level 6 costs **2,500 $CASH** total and unlocks **10 additional desks** (8 → 18).

All $CASH spent on upgrades is **burned on-chain**.

## Firm Level & Drop Rates

Your Firm's level affects more than just desk count. Higher-level Firms also improve your Intern pack drop rates — the probability of pulling rare, epic, legendary, and mythic Interns increases with each level. See [Interns](/game-overview/interns.md) for the full drop rate table.

This creates a meaningful upgrade incentive beyond raw capacity. A Level 6 Firm opening Intern Packs is statistically 3x more likely to land a Mythic Intern than a Level 1 Firm.

## Strategy Notes

**Buy or upgrade?** A new Level 1 Firm (1 SOL) gives you 8 fresh desks immediately. Upgrading an existing Firm from L1 to L2 costs 500 $CASH for 2 additional desks. Early on, buying new Firms is usually more desk-efficient. Upgrades become more attractive once you're approaching the 15-Firm cap and want to increase desk density and improve drop rates.

**When to upgrade:** Upgrade when your desks are full, and you have $CASH to spare. An empty desk earns nothing — don't upgrade for capacity you can't fill.
