Now in early access

Presell your idea.
Build when proven.

Set a pledge goal, collect real payments, build when you hit it. Miss it and everyone gets refunded automatically. No more waitlists. No more building things nobody wants.

Free to start. No credit card required.

$0 wasted on ideas that didn't ship
10 min from idea to live presell page
100% auto-refunded if goal not hit
Real money not likes, not waitlists

Waitlists are polite lies.
Money is the only signal.

Surveys, sign-ups, and upvotes all suffer from the niceness gap: people say yes to avoid awkwardness. A pledge is different. A pledge costs something.

✗ The old way

Build a Carrd page, paste a Mailchimp link, collect 200 emails. Launch to crickets. Find out nobody actually wanted to pay. Six months gone. $0 in revenue. Back to square one.

✓ With Proof

Set up a presell page in 10 minutes. Set your goal (e.g. 30 people at $49). Cards are captured but not charged. Hit the goal, build it, charge everyone. Miss it, refund everyone automatically. Zero risk for you or your backers.

"Anything short of a commitment to pay is noise. I've done 5 launches and the only thing that ever told me the truth was someone putting their card down."

Indie Hacker, r/SideProject

Three steps to validated demand.

From idea to proof in an afternoon. No engineers, no design skills, no existing audience required.

1

Build your presell page

Pick a SaaS-native template. Drop in your problem, your solution, your early-backer price. Set your pledge threshold: "I build this if 30 people commit $49." Live in 10 minutes.

No designers needed
2

Collect real pledges

Backers enter their card. It's captured but not charged yet. They see live progress: 14 of 30 pledged, 16 days left. Your campaign is listed in the Proof directory for free discovery.

Stripe-powered, zero risk
3

Hit goal or walk away clean

Hit your threshold: everyone gets charged, you get paid, you build it. Miss it: every backer gets auto-refunded, no manual work, no awkward emails. Either way, you have real data.

Auto-refund on miss

Everything you need to validate.
Nothing you don't.

Built for the moment before you write a single line of code.

Threshold mechanics

Cards are authorized at pledge time, charged only when your goal is hit. Auto-refund if you miss. The infrastructure that makes a presell actually work.

📄

SaaS-native templates

Not generic page builders. Templates built for software ideas: problem, solution, early price, backer perks. Done in minutes, not days.

🔍

Campaign directory

Every campaign gets listed in the Proof public directory, browseable by category. Relevant buyers can find your idea without you having to find them.

📊

Live backer dashboard

Backers watch progress in real time: X of Y pledged, days remaining. Post milestone updates. Trust is the currency that converts strangers into backers.

🚀

Post-campaign flow

When you hit goal, backers automatically become email subscribers with a "we're building it" confirmation. The presell is the start of the relationship, not the end.

🔗

Custom domain

Point your own domain at your campaign. Looks professional, builds trust, makes the whole thing feel like yours rather than a form on someone else's platform.
