What SellHack does
SellHack, operated by Cue Social LLC (an Ohio limited liability company headquartered in Chardon, OH), is a sales prospecting and lead generation SaaS platform focused on professional email discovery and verification. Its core product is a browser extension distributed through the Chrome Web Store and Safari, layered over a cloud-based 12-step real-time email verification engine that crawls and indexes professional email addresses and validates them by communicating with email servers. The platform also exposes a REST API for programmatic access, supports bulk email verification for list cleaning, and integrates natively with Salesforce CRM and the Replyify cold email automation suite.
The company sells on a tiered subscription model with monthly and annual billing: individual plans (Lite at $3-$5/month for 100 credits, Basic at $15-$19/month for 350, Starter at $30-$49/month for 1,000, Pro at $60-$99/month for 2,500) and team plans (Team Basic through Team Pro for up to 20 users at $150-$499/month), plus a Build-to-Suit custom tier and usage-based batch verification at $0.01-$0.02 per email. Customer segments span sales teams, marketing teams building custom audiences for retargeting, and recruiters sourcing candidates into ATS systems. Go-to-market is product-led growth via the browser extension with inside sales for team and Build-to-Suit plans, supplemented by a referral program, content marketing (blog and newsletter to 1,500+ professionals), and paid acquisition through Google Ads and AdRoll. The company is privately held, bootstrapped (with one disclosed $25,000 grant from Innovation Fund Northeast Ohio in 2015), employs 1-10 people, and operates with GDPR, CCPA, and PCI-DSS compliance.

SellHack competitors and assessment
Company assessmentDirect peers
- Hunter.io: Direct email-finding and verification SaaS with nearly identical freemium + credit-based subscription model and Chrome extension distribution. Closely comparable on product surface, target buyer (sales/marketing), and pricing architecture.
- Apollo.io: Sales intelligence platform combining email finding with contact database, sequencing, and enrichment; serves the same SMB and mid-market sales teams as SellHack with a broader feature set and significant venture funding.
- Snov.io: Email finder, verifier, and drip campaign platform with credit-based pricing and Chrome extension; competes head-to-head on individual sales-prospector use cases and overlapping CRM integrations.
- Lusha: B2B contact data browser extension with similar PLG, individual-to-team upgrade motion; competes directly for the same sales-prospecting user installing a single browser plugin.
- RocketReach: Email and phone lookup tool with browser extension and credit-based subscription; directly comparable on lookup workflow, pricing structure, and target sales/recruiting user.
- Aeroleads: Email prospecting Chrome extension explicitly named by a SellHack customer testimonial as a previous tool they replaced; directly comparable product, audience, and go-to-market.
Broad incumbents
- Salesloft: Larger sales-engagement platform with email finding and verification within a broader cadence/dialer suite; named directly in SellHack testimonials as a prior vendor some customers migrated away from.
- Replyify: Cold email automation and drip marketing platform integrated with SellHack; adjacent rather than directly competitive, but operates in the same outbound sales workflow and shared customer segment.
- ZoomInfo: Dominant B2B sales intelligence platform with proprietary contact data and far larger scale; overlaps with SellHack on email finding but serves as the enterprise incumbent against which lower-cost tools compete.
Emerging players
- Dropcontact: Europe-based B2B email finder and enrichment tool with similar automation and CRM-integration story; competes with SellHack on workflow automation but primarily addresses GDPR-conscious European buyers.
