Hikkari · Mobile repair marketplace

Repair quotes that compete, not quotes you have to trust.

A broken phone produces two questions nobody answers honestly: what is actually wrong, and what it should cost. Customers work with price opacity and unverifiable local shops. Shops work with walk-in traffic and open price wars.

Market: India
Vendor side: WhatsApp, no app install
Auction type: Blind, real time

The mechanic

Four steps, and the vendors only ever see one of them.

01
Diagnose
Symptoms arrive as free text, a guided decision tree, or a photo. All three signals fuse into one standardised repair category.
02
Match
Nearby verified vendors are matched by repair category and distance, using spatial indexing rather than a city-wide blast.
03
Bid blind
Vendors bid from WhatsApp. They never see each other's prices, so the auction cannot collapse into collusion.
04
Choose
Quotes stream in live with part tier, warranty days and turnaround. The customer picks on evidence.

Waiting for the first quote. Vendors nearby have been notified on WhatsApp.

Illustrative figures. Live bidding runs on the Hikkari platform.

Multi-tier quotes are the point. A compatible part at ₹1,850 with 30 days of warranty and an original at ₹4,850 with 180 days are different offers, and the customer can see that. Vendors compete on price, part tier, warranty and turnaround at the same time.

Capabilities

What the platform actually does.

Multi-path issue diagnosis

Describe the fault in Hinglish, walk a guided decision tree, or upload a photo. A fusion engine combines all three signals into one standardised repair category.

Hinglish-native search

Local embeddings plus vector and trigram matching resolve phrases like 'screen blank hogaya' to the exact repair category, without translating the customer first.

Vision assessment, privacy first

Blur detection, local OCR and face redaction run before anything reaches a cloud model, so a customer's screen contents and contacts are not uploaded to answer a repair question.

Verified vendor network

OTP plus full KYC: GSTIN, bank penny-drop, UPI and fuzzy name matching, with spatial indexing for location-based matching.

Blind live bidding

Vendors submit counter-bids by WhatsApp text command. Customers watch quotes arrive in real time. No vendor ever sees a competing price.

No app install for vendors

The whole vendor side runs on WhatsApp. The lowest-friction channel is the one shops already use all day.

Two sides, opposite incentives

The customer wants the lowest price. The shop wants to hold its margin.

For phone owners

You get a standardised diagnosis and competing quotes with warranty terms attached, instead of one shop's word for what went wrong.

Free diagnosis
Multiple independent quotes
Warranty days shown per quote
No vendor sees a rival price

For repair shops

You get verified leads in your own locality and set your own margin, without being dragged into a public price war.

Verified, KYC-checked leads
Bid from WhatsApp, no new software
You price your own margin
Blind bidding protects your rates

Privacy in the vision pipeline

A photo of a broken phone is also a photo of whatever was on the screen. Blur detection, OCR and face redaction run on our side before any image reaches a cloud model, so answering a repair question does not require uploading a customer's contacts, messages or photographs.

How we handle personal data

Are you a repair shop near a dense market?

Onboarding runs on OTP and KYC, and the bids run on WhatsApp. There is nothing to install.
