Build your micro-site with a tree of customizable widgets
CAPABILITIES
Your identity, structured for every touchpoint
Most profiles are either too static, too scattered, or too hard to update. Card gives you one flexible page that shows who you are, what you do, why people should trust you, and how they can take the next step.
POWERFUL FEATURES
Everything you need to build a smarter profile
Use widgets to create a profile that is more useful than a basic bio link and more flexible than a static business card.
BENEFITS
A better first impression in every channel
People discover you from emails, calls, social profiles, events, websites, and referrals. Card gives them one clear place to understand you and act.
You might have some questions!
Everything you need to know about building and sharing your Card.
What is Card?
Card is a smart profile and digital identity page. You can use it as a smart business card, link in bio, professional profile, portfolio page, contact page, or team member profile.
How is Card different from a normal link in bio?
A normal link in bio usually lists links. Card lets you build a full profile with widgets, proof, media, forms, calendars, social links, branding, and your Double.
What widgets can I add?
You can add widgets for your bio, company logos, tech stack, numbers, testimonials, links, social profiles, uploads, forms, calendars, text, books, location, sections, embeds, and more.
Can I customize how my Card looks?
Yes. You can customize themes, skins, colors, fonts, backgrounds, corners, shadows, media, and layout elements to match your personal or company brand.
Can I use Card as a digital business card?
Yes. Card can be shared through a link, QR code, email signature, social bio, event material, or direct outreach.
Can teams use Card?
Yes. Teams can use Cards for employees, departments, sales reps, consultants, creators, recruiters, leaders, and role-based identity pages.
Can I add my Double to my Card?
Yes. You can add your Double as a widget so visitors can browse your profile and ask questions from the same page.
Can Card replace my personal website?
For many professionals, yes. Card can work as a lightweight personal website, portfolio, link in bio, smart business card, and interactive profile. If you already have a website, Card can also work as your personal identity layer across channels.
