Circlinka

A reviewed cross-promotion network for Japanese indie B2B web tools.

About Circlinka

Circlinka is a reviewed cross-promotion network for small Japanese B2B web tools. Participating products install an asynchronous FlowBar with one script and introduce another approved, non-competing tool to visitors.

Flow Credit accounts for impressions and valid referrals so delivery can circulate fairly across the network. Hosts control daily limits, frequency caps, excluded destinations, and instant suspension. The SDK uses Shadow DOM for visual isolation and fails closed: if configuration, API, or runtime checks fail, it renders nothing and does not disrupt the host product. Signed, expiring redirects and idempotent settlement protect referral accounting.

Circlinka is currently recruiting its first five products in a closed beta. Registration is free. Approved Founding 5 products receive 1,000 Flow Credit and hands-on help with installation and the first connection. The service and onboarding are currently focused on Japanese-language B2B tools.

Key features

Reviewed B2B network

Quality before reach

Products are reviewed for a real public service, identifiable operator, Japanese B2B fit, and policy compliance before delivery.

One-script FlowBar

Integrate with minimal effort

Install an asynchronous script once. Circlinka manages approved destinations without requiring a host-site redeploy for each change.

Flow Credit accounting

Measure fair circulation

Impressions and valid referrals use an append-only, idempotent credit ledger so promotion and hosting can circulate fairly.

Host-site safety controls

Fail closed by design

Shadow DOM isolation, signed expiring redirects, origin checks, frequency caps, daily limits, exclusions, and instant suspension protect hosts.
