Everything you’re about to ask.

Cyna learns how your firm actually writes, your tone, structure, and the way you scope work, and drafts proposals that sound like you, not like generic AI. It gets sharper the more you use it.

Service firms whose work continues past the signature: digital and creative agencies, dev shops and software consultancies, marketing teams, accountants, and lawyers. If you send proposals, bill in stages, and then have to deliver, Cyna is built for you.

Those tools stop at accepted or paid. Cyna writes in your voice on the way in, then keeps the proposal, the signature and the money in one place. Delivery, milestones, change orders and a shared brief are rolling out next. Nobody else connects propose, bill, and deliver in one system of record.

Payments run through Stripe. Deposits collect on acceptance; milestones and retainers bill on schedule, with a card on file so follow-on charges just bill once they’ve said yes. Change orders are coming soon: extra work will need one explicit client tap to approve, never a silent pre-authorisation.

Starter is about $25/seat/mo for the win-and-get-paid core. Pro is about $49/seat/mo and adds the delivery layer plus free unlimited delivery seats. Enterprise is custom. Every plan starts with a 5-day free trial, no free-tier strings.
