Wire HubSpot into your warehouse without breaking attribution
Once your warehouse starts writing back to HubSpot, the lineage your attribution model depends on starts to drift. This is how to keep both sides honest.

What to write back to HubSpot — and what not to
Two kinds of fields belong in HubSpot: data the sales team needs to act on (account tier, product usage signals, churn risk) and data the marketing automation needs to segment on (lifecycle stage, last activity from product). Everything else — model scores, raw event counts, historical state — stays in the warehouse.
- Write back named, business-meaningful fields. Don't write back column names.
- Write back at most daily. Real-time write-back is rarely useful and frequently triggers workflow loops.
- Never write back into a HubSpot property that's also a workflow input unless you've audited every workflow that reads it.
Keep the attribution model on a diet
Once warehouse fields land in HubSpot, the temptation is to feed them straight into the attribution model. Don't. The attribution model's job is to explain what HubSpot saw — not what your warehouse already knows. Treat the warehouse-derived fields as decoration in the CRM and as inputs to a separate revenue model that runs on the warehouse.
Run two models, in two places, with two purposes. They'll disagree at the edges. That disagreement is the most useful signal you have — it tells you where HubSpot's lifecycle is lagging the actual customer state. Suppressing it by merging them is how attribution becomes superstition.
