Referral-Driven B2B / Post-Discovery Trust
Real work needs portable proof.
ProofIt helps referral-driven businesses replace scattered PDFs, GST certificates, work photos, and reviews with one professional business profile they can share when a customer asks: “Can you send company details?”
01 / Problem
The deal does not die at discovery. It dies at verification.
The moment
A cafe owner needs to hire a referred commercial painter. The quote is reasonable and the painter is highly recommended. But before signing off, the owner asks to see business details and past work to align with their co-founders.
“Can you send me your company details?”
The failure
The painter replies with loose photos, a messy WhatsApp text, and a raw registration scan. Worried about professionalism and accountability, the co-founders hesitate. The painter loses a deal they had already 'won.'
Core insight: Referral-driven businesses don’t need help getting discovered; they need help sealing the deal when a customer asks for proof. Originally conceived as a vendor discovery marketplace, we pivoted when research showed that the true drop-off happens after discovery, when vendors fail to package credibility under pressure.
02 / Actors
ProofIt serves both sides of the trust gap.
Vendor
Suresh, custom fabricator
Wins work through designer referrals but struggles to look corporate-ready when architects request formal company documentation.
Vendor
Anita, corporate caterer
Builds trust via word-of-mouth but needs a fast, unified way to present her food license, client reviews, and menu estimates in one step.
Buyer
Vikram, startup founder
Regularly hires referred vendors for office renovations and events, but needs a professional snapshot to align co-founders before signing off.
03 / Prototype
The idea is easiest to judge as a buyer flow.
The live prototype walks through the entire buyer journey—from receiving the vendor's profile link on WhatsApp, reviewing their verified work and past client feedback, to requesting a quote directly.
04 / Product Flow
A credibility link for the exact WhatsApp moment.
Referral & Details Ask
A customer discovers a vendor via word-of-mouth and starts a WhatsApp chat, asking: “Can you send your details?“
Vendor Shares Profile
The vendor replies with a single ProofIt link that packages their registration, portfolio, pricing, and client feedback.
Review & Quote Request
The customer reviews recent projects and reviews, selects services, and requests a custom quote through the profile.
WhatsApp Follow-Up
The quote request automatically routes back to the vendor’s WhatsApp, keeping the conversational momentum alive to close the sale.
What ProofIt is not
- Not a marketplace. We don’t match buyers and vendors; we help close deals after discovery.
- Not another directory. No listings, paid ads, or search rankings. We are a dedicated proof page.
- Not a website builder. No complex layouts or design headaches; just a clean, professional profile.
- Not a CRM. We don’t manage customer relationships; we just bridge the post-discovery credibility gap.

10 / Open Questions
The hard parts are moderation and identity protection.
Fake reviews & verification: How can we reliably verify that a review is tied to a real transaction without adding friction?
Identity abuse: How do we prevent bad actors from creating profiles pretending to represent existing reputable local businesses?
Trust moderation: What is the dispute process when a vendor wants to challenge or delete a negative review?
Privacy & ownership: What controls do vendors have over their search visibility versus direct link sharing?
