How to use these strings

Each boolean below is structured for Apollo's "Job titles" or "Keywords" filter. Paste the string into the matching filter, then layer firmographic filters on top (employee count, country, technologies). Don't use all signals at once or your list collapses to 5 companies.

Rule of thumb: start broad with the boolean, then narrow with 2-3 firmographic filters. Aim for 500-2000 companies per campaign.

B2B SaaS targeting

SaaS founders + technical co-founders

SaaS Founders Title filter
("founder" OR "co-founder" OR "ceo" OR "cto") NOT ("intern" OR "junior" OR "former" OR "ex-")
Layer: company size 5-50, industry "Software" or "Computer Software". Expect 8-15K results without country filter.

VP Sales at SaaS (mid-market)

SaaS Sales leaders
("vp of sales" OR "head of sales" OR "vp sales" OR "chief revenue officer" OR "cro") NOT ("former" OR "ex-" OR "open to work")
Layer: company size 50-500, industry Software. Removes job seekers and former roles cleanly.

RevOps leaders

SaaS RevOps
("revops" OR "revenue operations" OR "sales operations" OR "head of operations") AND ("director" OR "vp" OR "head" OR "lead" OR "manager")
RevOps is a great ICP for outbound tools, Clay, and CRM products. Layer: company size 100-1000.

Agencies and creative

Agency founders (excluding big networks)

Agency Founders
("agency owner" OR "founder" OR "managing director") NOT ("wpp" OR "publicis" OR "omnicom" OR "ipg" OR "havas")
Layer: industry "Marketing & Advertising" or "Design Services", company size 5-100. Excludes the big networks where outbound rarely converts.

Recruitment and PE

PE-focused recruiters

Recruitment PE
("recruiter" OR "executive search" OR "search consultant") AND ("private equity" OR "pe-backed" OR "buyout")
Niche but high ACV. Layer: country filter for UK / US. Expect smaller list (200-800 globally).

PE deal team and operators

PE Buy-side
("private equity associate" OR "vice president" OR "principal" OR "partner") AND ("private equity" OR "buyout fund")
For services targeting deal-makers. Layer: industry "Venture Capital & Private Equity".

E-commerce and DTC

E-commerce founders (Shopify/Magento ecosystem)

E-commerce Founders
("founder" OR "co-founder" OR "owner") AND ("ecommerce" OR "e-commerce" OR "dtc" OR "direct-to-consumer" OR "online store")
Layer: technologies "Shopify" or "Magento" for ecosystem fit. Expect 12-20K globally.

Hospitality SaaS targets (Jamezz ICP)

Restaurant owners + operations

Hospitality Operators
("restaurant owner" OR "restaurant operator" OR "f&b director" OR "operations manager") AND ("restaurant" OR "hospitality" OR "f&b")
Often invisible in Apollo. Combine with Google Maps scraping for better coverage (we cover that in the Clay waterfall resource).

Fintech

Fintech compliance and risk leaders

Fintech Compliance
("head of compliance" OR "chief compliance officer" OR "head of risk" OR "kyc lead") AND ("fintech" OR "payments" OR "banking")
High-intent for compliance tooling. Layer: country filter NL/UK/DE for European fintech hubs.

IT Services and MSPs

MSP and IT services owners (mid-market)

MSP IT services
("managing director" OR "founder" OR "owner" OR "ceo") AND ("msp" OR "managed services" OR "it services" OR "it support")
Layer: company size 10-100, country NL/BE for ONB-ICT style targeting.

The other 40+ strings cover: enterprise SaaS, B2B media, recruitment niches by sector, sustainability tech, manufacturing buyers, and four "anti-pattern" exclusion strings to remove low-quality results from any search.
