Your billing system is your collection engine.
Every new subscription is a future testimonial — if you ask at the right moment. Point a Stripe webhook at ReTestimonial and Smart Invites handles the rest: a three-email drip timed after onboarding, suppression for unsubscribes and bounces, a 90-day cooldown so nobody gets double-asked.

}Win the comparison page you don’t control.
SaaS buyers shortlist on G2, Capterra, and Trustpilot before they ever see your homepage. Auto-sync pulls your best reviews onto your own pages — where you set the layout, the context, and the call to action.
“Switched from a legacy tool — setup took one afternoon and the widget paid for itself.”
“The only tool our marketing and CS teams agree on. Inbox keeps everything in one place.”
“Support replied in 11 minutes on a Sunday. That's the bar now.”
Same pricing page. Different proof per visitor.
A founder coming off a G2 comparison needs a different story than an enterprise buyer arriving from your security docs. Contextual Proof Match reads UTM, referrer, page, and device at the edge — and swaps the testimonial in the same widget, in under 50ms.
Walk into the board meeting with a number.
“Testimonials help” is a feeling. Proof Impact is a ledger: every placement tracked, conversion lift measured against a holdout, and the delta attributed in dollars of MRR. Your proof stops being a brand asset and starts being a line item.
Everything above ships in one tool.
We wired invites to Stripe in twenty minutes. Three weeks later the pricing page was closing with proof we didn’t have last quarter — and Proof Impact told us exactly what it was worth.
