Bitcoin custody platform Onramp has raised a Series A at a $135 million valuation, led by Early Riders, with participation from strategic angel investors.
The company custodies more than $1 billion in client assets and has recorded zero security incidents since founding.
The custody problem
For years, bitcoin holders faced a binary choice: accept the single-custodian risk of an exchange, or shoulder the full operational burden of self-custody.
Onramp’s answer is Multi-Institution Custody — a 2-of-3 multisig quorum with keys distributed across Onramp, BitGo, and Coincover, giving clients full on-chain verifiability without managing keys themselves.
Onramp Finance
Onramp launched Onramp Finance in April 2026 to build a full financial life around bitcoin custody.
The platform offers bitcoin brokerage in all 50 states, a cash account with up to 5% in Onramp-funded rewards powered by Stripe’s Bridge infrastructure, a spending card with up to 1.5% cash back, a Bitcoin IRA, and direct gold access — all in a single account.
The company is also in active discussions with several US banks about tokenized deposit infrastructure and participation in the Multi-Institution Custody model.
Where the capital goes
The $12.5 million round funds two priorities:
Engineering and product, including continued buildout of Onramp Finance and expansion of the Multi-Institution Custody network to additional regulated custodians globally; and sales, marketing, and partnerships to bring white-label deployments to RIAs, fintechs, and traditional financial institutions.
Onramp also announced that David Thayer, former Partner at Blackstone, has joined as a strategic advisor.
Thayer stated:
“The simpler approach is always better: hold bitcoin, and hold it tight and right. Onramp built the architecture that makes this approach accessible to serious capital at any scale.”
Early Riders Partner Liam Nelson added:
“Onramp’s Multi-Institution Custody model is the most credible answer we’ve seen, and the clearest path to a category-defining business.”
