Proof is an identity verification platform that binds a verified identity to high-stakes authorizations — document signings, account access, financial transactions, and now AI agent actions — used in contexts like real estate closings and account openings. Its headline, "Verify once. Authorize everything," is organized around three explicit use-case categories: "Everything you sign," "Everything you do online," and "Everything an agent does for you." That last category centers on a self-described "x401 standard," positioned as letting AI agents conduct commerce while cryptographically proving human authorization — a forward-looking claim distinct from its otherwise conventional notarization and identity-verification business, which it backs with a $200B+-secured-annually figure and SOC 2, IAL2, and WebTrust credentials.

Proof design review: how the homepage is built

A long enterprise-identity page, about 7983 pixels at 1440 wide, that alternates white sections with two navy bands. The order is an announcement strip and floating nav bar, a centered hero over a fanned set of ID cards, a logo row, three cards, three alternating text-and-device rows, a navy developer band, a figures row, a navy product-menu band, a Defend feature, a card carousel, a closing panel and a navy footer. Blue #0046fa fills buttons and highlighted words, lime #b9ff81 marks the nav button and icon tiles, and navy #0c1635 sets the dark bands. Inter is the typeface.

Above the fold

A navy strip carries a blue "New" pill, with "Notarize now" and "Log in" at right. Below it a dark rounded nav bar shows the logo, "Platform", "Solutions", "Company" and "Pricing", and a white "Talk to sales" and a lime "Get Proof" button. The two-line centered headline sits above one subhead line and two buttons. Three tilted dark ID cards, the front one for "Sophia Caldwell", fan out beneath, then five grey logos including "RIPPLING".

Use-case cards and alternating feature rows

"Built for the moments that can’t go wrong" heads three pale-blue cards, each with a mockup, a "Power of Attorney" document, an "Open account" form and a dark agent panel, titled "Everything you sign", "Everything you do online" and "Everything an agent does for you". Half-and-half rows follow, each with a pill label and a blue key phrase, such as "Customers share what's needed and nothing more".

Developer band, figures and platform menu

A navy band sets a very large "x401" beside a lime tag, a lime button "Let's build something" and a code window. "A decade of securing high-stakes transactions" follows with three lime icon tiles, including "1,800+ live identity agents". A second navy band, "A single platform to secure any authorization", lays out six square tiles, "Notarize" through "Close", above wide rows for "Defend" and "Command Center".

Closing section and footer

"Securing every authorization on our network" pairs a large headline with a video screenshot framed by lime stripes and a blue "Start with Defend" button. "Industries we’re digitizing" runs a carousel of photo cards with category labels. "Protect your business with Proof" repeats the two buttons. The navy footer has a "Subscribe to our Newsletter" email field with "Sign up", then columns "Products", "Pricing" and "Industries".

On mobile

At 390px the page is about 12121 pixels tall. The hero buttons stack at full width and the logos wrap onto three lines. Cards and text-and-device rows become single columns, with the device below each headline. The six platform tiles stack as full-width rows, the footer columns fall to two across, and the announcement strip and floating nav bar are not visible at the top of the capture.
