“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
- Track everything under an auto-generated anonymous_id with graph8.
- Identify once the visitor logs in or submits an email.
- Map the anonymous_id to the permanent user_id.
- Rewrite history inside graph8 (ReplacingMergeTree) so every past row now carries the real user_id.
- 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: '[email protected]' }
});
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'.
