The alarm for life's real deadlines

Set it years ahead.
It rings until someone
deals with it.

Calendar events fire once and get ignored. RingUntil emails you — and everyone you add — on the date you choose, then keeps ringing on an escalating schedule until one of you clicks acknowledge.

Born from a true story

“The warrants expired unexercised. Money that was rationally theirs — gone. Not from a bad decision. From no decision.”

An investor held warrants in a fintech company — real upside, with an exercise deadline years away. Then the partner who made the deal left, the firm changed hands, and the deadline lived only in files nobody opened.

A calendar invite wouldn't have saved them. Something that rings every person involved, escalates, and refuses to go quiet until a human says “I've got it” — that would have. That's RingUntil.

Escalation chains, SMS & a human in the loop

If nobody acknowledges by a cutoff, a real person investigates and tracks down who needs to act. Built for securities deadlines — options and warrant expirations should never be dropped again.

Never let it slip again.

Set the reminder now. Forget it completely. It will find you — and everyone else — when it matters.
