Lead Enrichment

Build an AI Agent to Enrich Leads from Apollo into HubSpot Automatically

Give the agent a list of company domains or prospect names. It queries Apollo to find matching contacts, pulls funding stage, tech stack, headcount, and decision-maker details, then writes everything directly into HubSpot. A raw prospect list becomes a fully enriched, CRM-ready pipeline — without a single manual lookup.

How It Works

Five Steps From Raw List to Enriched CRM Pipeline

Drop in a list of domains or names. The agent finds the right contacts in Apollo, pulls every signal that matters — funding, tech stack, headcount, decision-makers — and loads it all into HubSpot, field by field, ready for your reps to work.

What You Get

Everything Sales Intelligence Should Do Automatically

The agent replaces hours of manual research with a single run — finding the right contacts, pulling every useful signal from Apollo, and loading a complete, accurate HubSpot record ready for outreach.

ICP-Matched Prospect Search

Agent searches Apollo using your Ideal Customer Profile — industry, company size, job title, geography, and tech stack. Finds the right contacts before enrichment begins so you're not wasting credits on bad-fit leads.

Deep People Enrichment

For every contact, Apollo returns job title, seniority level, verified email address, LinkedIn URL, phone number, and direct dial where available. No more guessing email formats or searching LinkedIn manually.

Organisation Intelligence

Bulk org enrichment pulls the company's latest funding round, total capital raised, headcount and growth rate, technology stack, and recent news mentions — the context a rep needs before the first touch.

Direct HubSpot Write

Every enriched field lands in the right HubSpot property — no CSV export, no manual import, no mapping spreadsheet. Contact created if new, updated if existing. Deduplication runs on every record before write.

Bulk Processing at Scale

Batch enrichment handles hundreds or thousands of contacts per run — not one at a time. Apollo's bulk APIs are used to process lists efficiently, with rate limiting and retry logic built in automatically.

Enrichment Audit Log

Every contact processed is appended to Google Sheets — with all enriched fields, the source record, and a timestamp. Full audit trail for ops review, data quality checks, and Apollo credit tracking.

Technical Details

Apollo + HubSpot Integration Deep Dive

How the agent connects Apollo's sales intelligence API with HubSpot's CRM to run a production-grade bulk enrichment pipeline — processing hundreds of contacts with full data fidelity and zero manual steps.

Apollo People Search

Prospect searching via Apollo filters by title, seniority, industry, company size, geography, and technology used. Returns matched contacts with confidence scores. Configurable to match your ICP exactly without manual filtering.

Bulk People Enrichment

People enrichment runs in batch — not one API call per person. Processes hundreds of contacts per request using Apollo's bulk endpoint. Returns verified email, job title, seniority, LinkedIn profile, and phone number for each contact.

Bulk Org Enrichment

Organisation enrichment via Apollo's bulk org endpoint pulls funding stage, total raised, last funding date, employee count and growth, tech stack (CRM, marketing tools, infrastructure), and company news signals per domain.

HubSpot CRM Write

Contact creation and update via HubSpot writes all enriched fields to the correct CRM properties. Deduplication searches by email before every write. New contacts created; existing contacts updated with fresh enrichment data only.

Google Sheets Logging

Analytics logging via Google Sheets appends every enriched contact — all fields, Apollo match confidence, HubSpot record ID, and timestamp. Enables Apollo credit auditing, data quality review, and enrichment run history.

Error Handling & Retry

Apollo rate limits, partial enrichment results, and HubSpot API failures all handled gracefully. Failed contacts queued for automatic retry with exponential backoff. No silent failures — every error logged with full context.

Agent Prompt
Build an AI agent that enriches leads from Apollo into HubSpot automatically:

1. Prospect Search — Accept a list of company domains or prospect names as input. Query Apollo using ICP filters (industry, job title, seniority, company size, geography) to find matching contacts at each company.

2. Bulk People Enrichment — Run Apollo bulk people enrichment on all matched contacts. Extract: verified email address, job title, seniority level, LinkedIn URL, phone number, and direct dial where available.

3. Bulk Organisation Enrichment — Run Apollo bulk org enrichment on all unique company domains. Extract: funding stage, total capital raised, last funding date, employee headcount and growth rate, technology stack, and recent news signals.

4. HubSpot CRM Write — For each enriched contact:
   - Search HubSpot by email to check for existing record
   - If found: update the existing contact with new enrichment fields
   - If not found: create a new contact with all enriched fields populated
   Map people enrichment data to contact properties and org enrichment data to company properties.

5. Google Sheets Audit Log — Append every processed contact to a Google Sheet with: all enriched fields, Apollo match confidence score, HubSpot contact ID, operation type (created/updated), and timestamp.

Integrations: Apollo (prospect search & bulk enrichment), HubSpot (contact & company write), Google Sheets (audit logging).
Frequently Asked Questions

Common Questions

What input does the agent need to start enrichment?
You can provide a list of company domains (e.g. stripe.com, notion.so), a list of prospect names with company, or ICP filter criteria (industry, title, company size, geography) and let Apollo do the initial search. The agent accepts CSV input, Google Sheets rows, or a manual trigger with parameters — whichever fits your workflow.
Will it create duplicate contacts in HubSpot?
No. Before creating any contact, the agent searches HubSpot by email address. If a match is found, it updates the existing record with new enrichment data. A new contact is only created when no match exists. This keeps your CRM clean regardless of how many times you run the enrichment pipeline on overlapping lists.
How many contacts can it process in a single run?
The agent uses Apollo's bulk enrichment endpoints rather than single-contact API calls, so it can process hundreds of contacts per run efficiently. Practical limits depend on your Apollo plan's credit allowance. The agent tracks credits used per run and logs them to Google Sheets so you can monitor usage and avoid unexpected overages.
Which HubSpot fields does it populate?
You define the field mapping during setup — Apollo enrichment fields mapped to HubSpot contact and company properties. Default mappings include: first name, last name, job title, email, phone, LinkedIn URL, company name, industry, employee count, funding stage, and tech stack. Any custom HubSpot properties can be added to the mapping without code changes.
Can it enrich contacts already in HubSpot, not just new ones?
Yes — you can point the agent at an existing HubSpot list or segment (e.g. contacts with missing tech stack data) and run enrichment against that group. The agent exports the list, queries Apollo for each contact, and writes the updated fields back. Useful for enriching legacy contacts or refreshing data on a schedule.
Does the tech stack data from Apollo stay current?
Apollo's tech stack data reflects what they detect at the time of query — it is not a live feed. For active pipeline accounts, you can schedule the agent to re-enrich on a monthly cadence to pick up tech stack changes, funding announcements, and headcount movements. Each re-enrichment run updates existing HubSpot records with fresh data rather than creating duplicates.
