The founding price: $19, until October 1.

Today we are turning on paid plans for LetSign, the agent-native proposal to contract to payment tool. Your agent authors the contract, your client opens a link, signs, and pays - you never drive their signing. The launch plan is one flat price: $19 per month. It is available until October 1, 2026, and everyone who locks it in before then keeps that price, with their payment rates, until October 1, 2028.

We are calling it the founding price because that is what it is: the price for the people who show up first. This post explains the three decisions behind it - flat, 0%, and a deadline that does not move.

Most tools in this category charge per seat, cap your envelopes, or hold the API behind a higher tier. We did none of that. $19 is the whole price: no per-seat pricing, no envelope limits, no API paywall. Your agent does most of the work in LetSign, and charging you per human seat for software that humans barely touch never made sense to us. One workspace, one flat number, everything included.

A flat price also keeps our incentives pointed the right way. We do not win when you add a seat or send more envelopes; we win when LetSign closes deals for you and you keep the subscription. That is the whole business model, stated in one sentence.

On the Launch plan we take 0% of the payments you collect through your own Stripe connection, up to $20,000 per month. We make money on the plan, not on your payments. Above $20,000 in a month, a 0.05% fee applies to the amount over the line - it exists to keep the plan honest at scale, nothing more. Collect $27,000 in a month and the fee is $3.50.

Everything runs on your Stripe: one-off payments, subscriptions, card-on-file for charge-later. Your money lands in your account on Stripe's schedule, not ours. Stripe's own processing fees are between you and Stripe, the same as if LetSign were not in the picture.

Launch discounts usually come with a countdown that quietly resets. A countdown that moves is a lie. Ours is enforced by code: on October 1, 2026, the Launch plan disappears from checkout and $49 per month becomes the price. No extensions, nothing to negotiate. And everyone who locked $19 keeps it, with their rates, until October 1, 2028.

The Free plan is not going anywhere either: $0 per month with a 0.20% fee on payments you collect, a real way to use the product with no time limit. The deadline only applies to the $19 lock.

If any of this sounds too clean, read the guarantee - we wrote it into the terms.
