Gemini Headquarters & Corporate Office

About Gemini

Gemini is a cryptocurrency, digital-asset custody, trading and financial-markets company founded in 2014 by Cameron and Tyler Winklevoss. The company originally built its reputation around a regulated U.S. crypto exchange and institutional custody platform and has since expanded into additional products including staking, crypto rewards, institutional services and prediction markets. Gemini Trust Company, LLC operates as a New York limited-purpose trust company regulated by the New York State Department of Financial Services.

Gemini underwent a major corporate change in September 2025, when Gemini Space Station, Inc. became a publicly traded company on the Nasdaq Global Select Market under ticker GEMI. This means older pages describing Gemini solely as a privately held Winklevoss-owned crypto company are now outdated. Gemini Space Station, Inc. is incorporated in Nevada, while Gemini Trust Company, LLC continues to operate the regulated U.S. exchange and custody business.

In 2026, Gemini launched its “Gemini 2.0” transformation and continues to be led by Tyler Winklevoss, Co-Founder and CEO, while Cameron Winklevoss serves as President. Gemini’s careers page describes the company as “headquartered in the Cloud,” with offices in New York City, Seattle, Miami, Singapore and London. Current legal agreements nevertheless provide New York physical addresses for Gemini Trust Company correspondence and regulated activities.

Gemini Products & Services

Cryptocurrency Exchange

Gemini provides a platform for buying, selling and converting digital assets. Retail customers can access crypto markets through web and mobile interfaces while viewing prices, balances and transaction information through their accounts.

Crypto Custody

Gemini provides regulated digital-asset custody for eligible customers and institutions. Gemini Trust Company operates as a New York limited-purpose trust company and qualified custodian, with customer assets segregated from the company’s own assets.

Institutional Trading

Institutional customers can use Gemini for crypto trading, custody and liquidity solutions. These services are designed for professional investors, businesses, financial institutions and other entities requiring more advanced infrastructure than ordinary retail accounts.

Over-the-Counter Trading

Gemini provides OTC services in selected jurisdictions for larger digital-asset transactions. OTC execution can help qualifying institutional customers trade significant positions outside normal retail order flows.

Gemini Mobile App

The Gemini mobile application enables eligible customers to manage accounts, trade supported assets and monitor portfolios from smartphones. Availability depends on jurisdiction and applicable regulatory requirements.

Crypto Rewards Credit Card

Gemini has offered a credit card that provides qualifying crypto rewards on purchases. The product forms part of Gemini’s broader effort to connect digital assets with traditional consumer financial services.

Staking

Gemini provides staking or staking-related services for supported assets in eligible markets. Staking availability and terms vary according to asset, jurisdiction and current regulatory requirements.

Prediction Markets

Gemini expanded its platform into regulated prediction-market products, which it now identifies as part of its broader crypto and markets strategy. In 2026, Gemini announced distribution collaborations for its regulated prediction-markets offering.

Fiat Deposits and Withdrawals

Eligible customers can fund Gemini accounts using supported fiat currencies and approved payment methods. Gemini’s Trust Center currently reports support for eight fiat currencies.

Digital Asset Transfers

Gemini supports deposits and withdrawals of eligible cryptocurrencies between Gemini and external blockchain addresses. Customers should verify supported networks carefully because blockchain transfers may be irreversible.

Gemini Dollar

Gemini has historically issued and supported Gemini Dollar, a U.S.-dollar-linked digital asset designed to operate within regulated digital-asset infrastructure.

Institutional Custody Accounts

Businesses and professional investors can establish custody arrangements designed for institutional governance, security and reporting requirements.

Security and Compliance

Gemini emphasizes security controls including SOC audits, ISO standards and regulated custody. Its Trust Center reports SOC 1 Type 2 and SOC 2 Type 2 examinations and emphasizes its full-reserve model.

Developer Platform

Gemini provides API and developer tools for businesses and developers building trading, market-data, custody or digital-asset integrations.

Gemini Frontier Fund

Gemini Frontier Fund is Gemini’s strategic venture investment operation focused on early-stage crypto projects and startups.

How to Reach a Real Person at Gemini

The most reliable route for a Gemini account issue is the official Help Center and Customer Support system. Gemini’s current User Agreement also publishes 1-866-240-5113 as a toll-free U.S. Customer Support number and support@gemini.com for account-related assistance. Have your account email, transaction ID, timestamps, affected asset, relevant wallet address and screenshots ready, but do not send private keys, seed phrases, passwords or authentication codes.

If the issue concerns a formal complaint or trading error, clearly state that you are lodging a complaint so it receives the appropriate review. Gemini also accepts written complaints at 600 Third Avenue, 2nd Floor, New York, NY 10016. Investors should use investors@gemini.com, while media requests should use press@gemini.com.

Former / Historical Headquarters

How to File a Complaint Against Gemini

Complaints may involve account restrictions, deposits, withdrawals, crypto transfers, trading errors, fees, identity verification, unauthorized activity, custody, credit-card issues or another Gemini service. Before escalating, collect transaction IDs, blockchain hashes, screenshots, dates, amounts, support-ticket numbers and relevant account information. Never include private keys, passwords, seed phrases or one-time authentication codes.

Step 1: Contact Customer Service

Use Gemini’s Help Center or call 1-866-240-5113. Explain the problem in chronological order and provide transaction identifiers or other evidence. Gemini’s current User Agreement expressly identifies this number as a complaint and Customer Support route.

Step 2: Contact the Relevant Department

Security incidents, trading issues, custody questions and institutional matters may need specialized review rather than ordinary account support. Make the nature of the issue explicit so the case can be routed to the correct team, especially where funds are missing, access is restricted or a blockchain transaction is involved.

Step 3: Request Supervisor or Management Review

If the first response does not resolve the matter, reply within the same support case and request escalation. Provide the previous ticket number and state precisely what remains unresolved. Maintaining one documented case history can make the investigation easier for Gemini’s support and compliance teams.

Step 4: Use the Company’s Written Complaint Channel

Gemini allows formal complaints through Customer Support and written correspondence. Send a clear complaint containing the account email, transaction details, relevant dates and requested resolution. Avoid sending unnecessary sensitive credentials.

Step 5: Contact Corporate Headquarters

Written complaints may be sent to Gemini Trust Company, LLC, 600 Third Avenue, 2nd Floor, New York, NY 10016. Gemini’s current legal terms specifically publish this address for Customer Support correspondence and complaints.

Step 6: Use the Specialized Complaint or Dispute Department

For trading errors, custody disputes or regulated-service complaints, clearly request review under Gemini’s formal complaint process rather than treating the matter as a general help question. Institutional customers should use the contractual contact routes applicable to their account and custody agreement.

Step 7: File With the Appropriate Regulator

Gemini Trust Company is regulated by the New York State Department of Financial Services, making NYDFS a potentially relevant regulator for certain regulated virtual-currency or trust-company complaints. Other state regulators may have authority depending on the customer’s location and product involved.

Step 8: Use Consumer Protection or Financial Dispute Options

Payment-card issues may also be addressed through the card issuer, while bank-transfer issues may require coordination with the sending or receiving bank. Customers should understand that cryptocurrency transfers themselves can be irreversible, so external payment disputes should be pursued only where they legitimately apply.

Step 9: Consider Formal Legal or Arbitration Procedures

If a significant dispute remains unresolved, review the current Gemini User Agreement and the terms applicable to the relevant service. These documents establish contractual rights, dispute provisions and jurisdiction-specific rules. Because Gemini’s legal terms change periodically, use the version in force when preparing a formal claim.
