Our Origin
"Whether it's Balogun, Ariaria or Onitsha Market, we always bought together. Twenty women, one supplier, one price nobody could get alone."

For generations, Nigerian market women have practiced ajo — a rotating savings and group-buying tradition. Twenty women pool funds on a Thursday, walk to Balogun, Ariaria, Onitsha or OilMill markets together, and negotiate bulk prices no individual could command.

It worked because everyone knew everyone. But as commerce moved online and groups formed between strangers, trust broke down. Who holds the money? Who pays the seller? What if someone disappears?

CollabBuy digitizes the ajo tradition for the digital age. Cryptographic escrow and Split-PIN authorization mean no single person holds the money — the seller only gets paid when every member confirms.

Process

How CollabBuy works

Four steps from strangers to a completed group purchase — with funds always protected in escrow.

01
📋

Create a Collab

Set the item, total amount, contribution limits, and how many buyers you need. Share the collab link to find co-buyers online or in your network.

→
02
👥

Members Join & Lock Funds

Each member contributes their share. Funds are locked immediately in Paystack escrow — nobody can withdraw until the collab completes or is cancelled.

→
03
🏦

Verify the Seller

The host adds the seller's bank details. Paystack verifies the account name automatically. Every member confirms they see the correct account before proceeding.

→
04
🔐

Split-PIN Releases Payment

Each member holds a unique portion of the authorization PIN. Only when every member enters their digits does the payment execute — trustless by design.

Split-PIN Technology

No single person controls the payment.

The full authorization PIN is never known to any one person. Each member's digits are assigned at random. The seller is only paid when every portion is correctly entered.

  • Server generates a random PIN — no one sets it manually
  • Each member receives only their digit positions via secure notification
  • Only the SHA-256 hash is stored — the full PIN is never persisted
  • A hash mismatch resets all entries — no partial exploits
  • All entries expire after 15 minutes if not completed
  • Maximum 5 attempts before the collab is locked for review
Use Cases

What people buy together

From Balogun Market fabric runs to shared Netflix subscriptions — CollabBuy works for any group purchase where trust matters.

🛍️

🎟️

Event Tickets

Buy Table for 4 Tickets at your favourite comedy show, block tickets for concerts or sporting events at group discount rates. Funds only release when the full block is paid — no one carries the risk alone.

Building Materials

Neighbors on the same street combine to buy cement, tiles, or iron rods at factory-direct bulk prices nobody could access individually.

₦80,000 each · 5 members
CollabSafe™

Safety built into every transaction.

CollabSafe is our passive security layer — monitoring collab health in real time and alerting trusted contacts if something looks wrong.

🔒

Escrow Protection

Funds are locked the moment a member joins. Nobody — including CollabBuy — can access escrow funds before the Split-PIN releases them to the verified seller.

👁️

Trusted Contact Alerts

Designate a trusted contact who gets notified if a collab stalls, if a member goes silent, or if unusual activity is detected during authorization.

📋

Verified Seller Account

Every seller's bank account is resolved and verified by Paystack before being shared with members. Every member must confirm the account details before any payment proceeds.

🚨

Cancellation Penalty System

Members who back out after locking funds pay a 5% penalty — 60% distributed to remaining members, 40% to the platform. Keeps everyone accountable.
