What is Echo?
Echo is a platform for investing in early-stage crypto projects, run by Gm Echo Manager Ltd. Its Sonar product, run by Gm Echo Clicks Ltd from the British Virgin Islands, verifies buyers for public token sales that projects host themselves. Echo takes 5% of user profits per private deal; Sonar charges investors no fees.
How Echo works
Echo has two products.
In private group investing, a lead investor creates a group and shares deals. Members choose deal by deal whether to follow the lead on the same terms, and all participants are rolled up into a single entity that invests in the company. Investments run onchain in USDC. The lead never touches your USDC, and the lead earns a share of followers' profits only when those deals make money.
Sonar is separate: it is self-hosted sale infrastructure. The project configures pricing, compliance rules and limits in the Echo Founder Dashboard and builds its own sale website. Buyers verify identity through Sonar's KYC or KYB, then commit funds to a smart contract the project owns, using signed purchase permits. Pricing is either a fixed price or an English auction where everyone at or above the clearing price pays that price. After the commitment window, the project decides how much of each commitment to accept, for example pro-rata, bottom-up fill or first come first served, and unaccepted funds are refunded onchain.
How to start with Echo
- For Echo groups, you sign up, connect an X or Farcaster account, and pass an eligibility check based on your local law and investing experience.
- KYC runs through Sumsub.
- Proof of address must be under 3 months old; screenshots, mobile phone bills and neobank statements such as Revolut are not accepted.
- Deals you are not eligible for, usually because of where you live, are hidden from you.
- The group lead sets the minimum and maximum per deal, and deals fill first come first served.
- For Sonar, there is no central list of sales.
- You find a sale on the project's own site, connect your verified Sonar profile, and Sonar returns only the fields that sale needs, such as residence or accreditation.
- You can verify as an individual or as an entity you control.
Echo fees and limits
- Echo takes 5% of your profit on each private deal and says this is its only revenue.
Each deal also carries shared operating costs paid by the SPV investors, such as token warrant fees set by founders and regulatory filing costs for the investment vehicle. Sonar charges investors nothing because projects pay for it.
Risks to know before using Echo
- Echo's own disclosure calls early-stage investments highly illiquid and suitable only for investors who can afford to lose all of their capital.
- Deal information is confidential, and sharing it off-platform or contacting founders directly can get you banned.
- Sonar does not list, vet or run sales: allocation, payment and confirmations are handled by each project's own system and contract, so smart-contract and delivery risk sits with that project.
- Sonar also issues no receipts or investment confirmations.
