A.Billi

A.Billi presents public corporate ownership records alongside local alternatives, so communities can make informed choices together. Structural facts from public filings. No scores, no opinions. Your data stays on your device.

THREE TABS

• MY LIST — A shopping list that remembers what you buy, annotates each item with its corporate parent using public ownership records, and surfaces local alternatives in the same category when they exist. Tap an item to follow the ownership chain or swap to a local option.

• YOUR MONEY — An aggregate transparency view of how your spending concentrates across parent companies. See your highest-concentration corporations and your independent share. All processing happens on-device — A.Billi never sees your individual spending data.

• NEIGHBOURS — Your local community node. See what alternatives your neighbours are finding, what products people wish existed locally, and what proposals are being discussed. Reasons boards use a Polis-style structure: people react agree, disagree, or pass on each reason, and the system surfaces which reasons cross groups and which divide them. Designed for thinking together, not for generating winners and losers.

PUBLIC RECORDS, PRESENTED TO THE PUBLIC

Corporate ownership is public information. It's just not easy to find. A.Billi gathers data from corporate filings, shareholder disclosures, lobbying registries, and other public sources — then presents it alongside the brands people actually buy. The same data that's always been available, made accessible to the communities it affects.

We never rate companies. We don't maintain a "boycott list." We don't recommend purchasing decisions. We present sourced public-record facts and let users discuss what they see with their community.

LOCAL ALTERNATIVES, WHEN THEY EXIST

For corporate products, A.Billi surfaces independent and local alternatives in the same category — grocery, beverages, household, services. Local listings are contributed by community members and verified through public business records. Same need. More of your money stays in your community.

PRIVACY-FORWARD BY DESIGN, NOT BY POLICY

• On-device processing — Receipt scanning and spending analysis happen locally. Images never leave your phone.
• Anonymous by default — Browsing requires no account. The Observer tier keeps everything on your device.
• Aggregate only — Community data is anonymous counts and demand signals. No individual activity is ever surfaced.
• Minimum thresholds — Community signals require a minimum number of contributors before becoming visible. No individual can be identified.

No ads. No tracking. No analytics SDK. No data sold, ever.

TIERED IDENTITY

• Observer — no account, everything stays on your device.
• Participant — sign in with Apple, Google, or email to join your community node, post proposals, and react on reasons boards. An opaque participant ID is used for community activity; your email is never displayed or shared with other users.
• Verified — bank-linked via Plaid for spending verification only. Never balances, never account numbers, never transaction details. Currently in beta with Plaid sandbox; production rollout is gradual.

BUILT AS PUBLIC INFRASTRUCTURE

A.Billi is a product of Parallel Systems. We're building a transparency and coordination layer for community economies — neutral, accountable, patient. The same way a public library is infrastructure for knowledge: not an opinion, not a campaign, not an advocacy tool. A place for communities to see clearly and decide together.
