Revenue analyst agent for a mid-size hybrid PLG and sales-led SaaS company on HubSpot that resolves workspaces, subscriptions and deals into one account record

What The Account Resolver does

The founder and leadership team of a 51 to 200 person B2B SaaS company keep asking simple questions that nobody can answer quickly: how many trials turned into paying accounts last month, whether expansion came from self-serve upgrades or from reps, and which large accounts are paying for seats they barely use. The answers exist, but they are split across HubSpot (deals, contacts, companies), the billing system (subscriptions, invoices, plan changes) and the product database (workspaces, users, usage events), and the three use different IDs that nobody has ever joined. The Account Resolver owns that join. It maintains a mapping table that links each product workspace and billing customer to a HubSpot company, reads all three systems through read-only MCP connectors over a small warehouse, answers leadership's questions in plain English with the definition, sources and match confidence stated, and publishes a weekly executive digest. Because the company wants it built and maintained for them, the agent's connectors, metric definitions and mapping rules are monitored and updated as billing plans, product schemas and HubSpot properties change.

Built on HubSpot

HubSpot is the right home for the people-facing side: account owners, lifecycle stages and workflows already live there, and Breeze agents can act on signals written to company properties. What HubSpot does not do well on its own is join a separate billing system and a product database at the account level with auditable logic, which is the core problem here. A custom AI build reading a small warehouse through read-only MCP connectors handles that join, keeps definitions governed in one place, and writes only the useful results back into HubSpot. n8n handles the scheduled loads and alerts, and Databox can display the same governed metrics as a dashboard for anyone who prefers charts to questions.

What starts it

• A founder or executive asks a revenue question in the team chat channel or the HubSpot sidebar
• Monday morning schedule for the weekly executive digest
• A new workspace, billing customer or HubSpot company appears that does not match an existing account
• A trial ends, a plan changes or a subscription cancels in the billing system
• A nightly data check finds a metric moved outside its normal range or a source stopped syncing

What it reads

• HubSpot companies, contacts, deals, lifecycle stages and owner assignments
• Billing system subscriptions, invoices, plan changes, refunds and cancellations
• Product database workspace, seat and aggregated usage tables (read replica only)
• A warehouse (for example BigQuery or Snowflake) holding the account mapping table and governed metric models
• A metric dictionary document defining ARR, trial conversion, expansion, contraction and product-qualified account
• HubSpot marketing touch and form data used to label how an account first arrived

When a person takes over

• RevOps reviews the unmatched and low-confidence account queue weekly, because a wrong join between a workspace and a HubSpot company would misstate ARR and credit the wrong motion
• Finance approves any change to how ARR, expansion or churn is defined, and signs off on figures before they go into a board deck or investor update
• The account owner or customer success lead decides what to do with a seat-underuse or product-qualified flag, since the agent reports the signal but does not contact customers
• The data maintainer takes over when a source schema changes or a sync fails, and the agent states the numbers are incomplete rather than estimating

Rules it follows

• All connectors are read-only; the agent can write only to a defined set of HubSpot company signal properties and never edits deals, subscriptions or product data
• Every answer states the definition used, the date range, the sources and how many accounts were excluded as unmatched, and the agent refuses to answer when match coverage falls below the threshold finance set
• Self-serve revenue is never credited to sales unless a HubSpot deal or owner existed before the first payment, and the agent shows which rule applied when asked about attribution
• Usage data is aggregated to account level before it reaches the agent, so individual end-user activity and personal details from the product database never appear in answers, logs or the digest
• Pre-sales research activity (site visits, content views) is reported as context only and never presented as proof that marketing or sales caused a conversion

How you know it works

• Share of paying accounts with an exact match across HubSpot, billing and product data
• Time from a leadership question to a sourced answer, compared with the previous manual process
• Number of weekly digests delivered on time with no stale or failed-source sections
• Product-qualified and seat-underuse flags actioned by an owner within the agreed window
• Count of revenue figures challenged in leadership meetings that trace back to a definition or match error

From pilot to live

1. Pilot: resolve and defineConnect HubSpot, billing and a product read replica to the warehouse, build the account mapping table, and agree the metric dictionary with finance. The agent answers questions for the founder only, and every answer is checked against a manual pull.
2. Expand: digest and signalsTurn on the Monday digest for the leadership team and start writing product-qualified and seat-underuse properties to HubSpot for a small set of account owners. RevOps works the unmatched queue down until coverage is stable.
3. Full rollout: run and maintainOpen question access to sales, customer success and finance leads, connect the signals to HubSpot workflows and Breeze agents, and move to ongoing maintenance with monitored syncs, schema-change alerts and a quarterly review of definitions as pricing and plans evolve.
