# HubSpot Lookalike Account Builder

Turn your best existing customers into a net-new prospecting list. Profile a set of closed-won HubSpot accounts with MoltSets firmographics, work out the shared industry, employee range, and revenue range, then search for similar companies not already in HubSpot. The output is a target account list ready to hand to a rep or load into an outbound sequence.

## Triggers

"Build a lookalike target list based on my closed-won accounts in HubSpot", "find companies similar to my best customers that aren't in HubSpot yet". Use when the user wants net-new target accounts modelled on their closed-won customers.

## Requirements

- HubSpot remote MCP (mcp.hubspot.com) and the MoltSets MCP connected in the same client
- Custom objects are not reachable through HubSpot's remote MCP - create standard company records

## Chain

```
HubSpot closed-won accounts
  -> hubspot/search-crm-objects        (companies with an associated closed-won deal, optional filters)
  -> MoltSets:
       search_companies                (domain -> industry, employee_range, revenue_range)
  -> derive lookalike profile          (dominant industry, employee range, revenue range across the set)
  -> MoltSets:
       search_companies                (industry + employee_range + revenue_range -> candidate companies)
  -> exclude domains already in HubSpot
  -> hubspot/create-object             (optional: create the new companies as target accounts)
```

## Inputs

- **Seed accounts** - which closed-won accounts to profile (all, a segment, or a named list)
- **Profile weighting** - which firmographic fields matter most for the lookalike match (industry, size, revenue)
- **List size** - how many net-new accounts to return
- **Exclusions** - domains already in HubSpot, competitors, or a do-not-target list

## Steps

1. Pull the closed-won accounts (or a filtered subset) from HubSpot.
2. Run `search_companies` by domain on each to get industry, employee range, and revenue range.
3. Aggregate the results into a lookalike profile: the dominant industry or industries, and the typical employee and revenue range across the seed set.
4. Run `search_companies` again using that profile as the filter to surface candidate companies.
5. Exclude any domain that already exists in HubSpot, and any domain on the exclusion list.
6. Return the ranked candidate list, and optionally create the new companies in HubSpot as target accounts.

## Output

| Company | Domain | Industry | Employees | Revenue | Match Reason | In HubSpot Already |
| --- | --- | --- | --- | --- | --- | --- |

```
Seed accounts profiled:      X
Dominant industry:           X
Employee range:              X
Revenue range:               X
Candidates found:            X
Net-new (not in HubSpot):    X
MoltSets tokens used:        X
```

## Tips

- If your closed-won accounts span multiple distinct industries, run the lookalike search per cluster rather than averaging across all of them.
- Use `domain` exclusion against your full HubSpot company list, not just the seed set, so you don't resurface existing customers or open deals.
- Pair this with the buying committee expansion skill once a lookalike account is created, to find the right contacts inside it.
