Zero‑Blind‑Spot Attribution: graph8 Retro‑Stitches Every Buyer Journey in Seconds

“Half the contacts in our CRM still say Anonymous—and it’s killing our attribution.” —Every frustrated growth leader, 2025

graph8’s Anonymous → Named identity stitching rewrites a visitor’s entire anonymous history onto their user record the instant they identify themselves—no batch jobs, no sky‑high warehouse bills, no more blind spots.

The $15 M “Anonymous” Problem

Data Gap	Lost Value	Example
Attribution	Wasted ad spend & wrong channel bets	Paid search gets credit even though the deal started with a webinar
Personalization	Generic nurture, lower conversion	Chatbot can’t reference pages the lead visited yesterday
Sales Context	Longer discovery calls, missed pain points	SDR opens Contact and sees zero history

Gartner estimates data silos cost the average B2B organization $15 M per year in missed opportunities. A huge chunk of that loss traces back to anonymous visitor data that never gets tied to real people.

How graph8’s Identity Stitching Works

1. Track everything under an auto‑generated anonymous_id with graph8.
2. Identify once the visitor logs in or submits an email.
3. Map the anonymous_id to the permanent user_id.
4. Rewrite history inside graph8 (ReplacingMergeTree) so every past row now carries the real user_id.
5. Fan‑out updates to CRM, data warehouse, Slack, and personalization layers in < 5 s.

// Identify once the visitor logs in
g8('identify', {
  userId: '12345',
  traits: { email: 'alice@acme.com' }
});

Why graph8 ClickHouse + ReplacingMergeTree?

• Append‑only writes—no locks.
• Background merges dedupe automatically.
• Proven at petabyte scale (it powers Yandex search logs).

Technical Deep‑Dive

CREATE TABLE events
(
    event_id       UUID,
    user_id        String,   -- may be empty pre‑login
    anonymous_id   String,
    user_key       String ALIAS coalesce(user_id, anonymous_id),
    event_type     LowCardinality(String),
    ts             DateTime,
    props          JSON
) ENGINE = ReplacingMergeTree(event_id, user_key)
ORDER BY (user_key, ts)
PARTITION BY toYYYYMM(ts);

Stitch event inserts updated rows; merges collapse duplicates.

GDPR erasure: ALTER TABLE events DELETE WHERE user_id = '12345'.
