Apollo is the #1 B2B database (10M+ contacts worldwide). Most users use 10% of its power.
This guide shows how to use Apollo's advanced filters to find exactly your target prospect in 5 minutes.
Apollo Basics: How It Works
- Create Apollo account (free tier: 10 searches/month)
- Search → Add Filter
- Combine filters (title + company size + country + technology)
- Apollo returns matching contacts
- Export as CSV → Upload to Instantly/SmartLead
Expected Results:
- Focused search: 2,000-5,000 contacts
- Broad search: 10,000-25,000 contacts
- Quality: 60-70% accurate emails
Key Filters (With Examples)
Filter 1: Territory/Location
Use Case: Target specific country or region.
Examples:
- Country = United Kingdom (returns all UK contacts)
- Country = Germany (returns German B2B only)
- City = London (returns London-based only)
- Region = California (for US)
Tip: Combine with other filters to narrow. "Country = UK" alone returns 50K+ contacts (too broad).
Filter 2: Job Title
This is the most important filter. Get it right.
Decision-Maker Titles by Vertical:
SaaS/Tech:
- VP Growth
- Head of Sales
- Director of Business Development
- Founder
- Chief Revenue Officer
Fintech:
- Head of Partnerships
- VP Growth
- Director of Strategy
- Chief Product Officer
Agencies:
- Founder
- Managing Director
- VP Business Development
- Director of New Business
Enterprise Software:
- VP Sales
- Head of Enterprise
- Director of Sales
- VP Partnerships
How to Use:
- Filters → Job Title
- Search for title (e.g., "VP Growth")
- Apollo suggests matching titles
- Select multiple if needed (VP Growth OR Head of Sales)
Pro Tip: Don't select "Sales Manager" or "Sales Rep." Too junior. Target Director+ level.
Filter 3: Company Size
Different verticals need different company sizes.
Company Size Definitions (Apollo):
- 1-10: Seed-stage startups
- 11-50: Early-stage (Series A)
- 51-200: Growth-stage
- 201-500: Series B/C
- 501-1000: Late-stage
- 1000+: Enterprise
When to Use:
- SaaS: 10-500 employees (highest response)
- Agencies: 10-100 employees (small to mid)
- Enterprise Software: 500+ employees (longer sales cycle, higher deal value)
- Fintech: 50-500 employees (growth + profitability)
How to Filter:
- Filters → Company Size
- Select range (e.g., 51-200)
- Apollo filters results
Filter 4: Company Industry
Narrow by industry vertical.
Common Industries:
- Software / SaaS
- Fintech / Financial Services
- Marketing / Advertising
- Staffing / Recruitment
- Logistics / Supply Chain
- Healthcare Technology
- HR Technology
How to Use:
- Filters → Industry
- Type or select from list
- Apollo returns matching companies + contacts
Pro Tip: Too broad (e.g., "Technology") returns millions. Go specific ("SaaS" or "HR Technology").
Filter 5: Company Funding
Find well-funded companies (more budget = better buyers).
Funding Filters:
- Last Funding: 0-6 months ago (highest intent)
- Funding Stage: Seed, Series A, Series B, Series C+
- Funding Amount: $1M-10M, $10M-50M, $50M+
Use Case: Target companies that raised funding recently = high growth = budget available.
Example Search:
- Industry: SaaS
- Country: UK
- Funding Stage: Series A or Series B
- Last Funding: Within 6 months
- Title: VP Growth
Result: ~500-2,000 highly-qualified UK SaaS companies that just raised funding.
Filter 6: Technologies Used
Find companies using specific tech (shows buying intent + budget).
Common Technologies:
- Salesforce (using CRM = has revenue team)
- HubSpot (has marketing/sales operations)
- Stripe (handling payments = profitable)
- AWS (infrastructure = tech-forward)
- Intercom (customer communication = growth-focused)
Use Case: Companies using Salesforce have revenue teams = higher propensity to buy sales tools.
How to Filter:
- Filters → Technology
- Type technology (e.g., "Salesforce")
- Apollo returns companies using it
Advanced Use:
- Salesforce + HubSpot = highly mature sales team
- Stripe + Intercom = profitable, customer-focused SaaS
- AWS + Datadog = engineering-forward startup

Pro Tips for Apollo Searches
Tip 1: Use "OR" for Job Title
Don't search "VP Growth" alone. Use "VP Growth OR Head of Sales OR Director Growth" to capture variations.
Tip 2: Don't Over-Filter
Each filter narrows results:
- Country = 50K+
- Country + Industry = 10K+
- Country + Industry + Size = 5K+
- Country + Industry + Size + Title = 1K-3K
Stop when results are 1K-5K (sweet spot for manageable campaigns).
Tip 3: Export and Test
Export 500-1,000 from search as CSV. Test in Instantly/SmartLead with small pilot (50/day). If response rate >3%, scale to full list.
Tip 4: Technology Filter is Powerful
Companies using specific tools = buying intent. If searching "CRM buyers," filter for Salesforce OR HubSpot.
Tip 5: Combine Funding + Recency
"Series A funded in last 6 months" = recent money = near-term buying.
Common Mistakes in Apollo Searches
Mistake 1: Too Broad
- Search "Technology" industry alone = 500K+ results (unusable)
- Fix: Narrow to "SaaS" or "HR Technology"
Mistake 2: Too Narrow
- Search "VP Growth" + "Series B" + "London" = 10 results (too small)
- Fix: Remove "London," expand to "UK"
Mistake 3: Junior Titles
- Searching "Sales Manager" instead of "VP Sales" = wrong audience
- Fix: Target Director+ level
Mistake 4: Wrong Geography
- Searching "Global" (no country filter) = millions of results
- Fix: Pick 1-3 countries
Mistake 5: No Technology Filter
- Generic searches miss high-intent prospects
- Fix: Add "Salesforce" or "HubSpot" to find buyers
