Built by Sales Engineers Who Got Tired of Template Spam
We built CortexSales because every outbound tool we tried did the same thing: blast templates without understanding the prospect. Personalization meant swapping a first name. Research meant checking a LinkedIn headline. We knew there had to be a better way.
Make every cold email worth reading
Our mission is simple: back every outreach with real evidence. We cross-reference SEC filings, earnings transcripts, job postings, technographics, and press releases to find genuine pain points -- then craft emails that speak directly to what the prospect actually cares about. Today we focus exclusively on the USA B2B market, with plans to expand internationally.
Principles that guide every feature we ship
Evidence Over Assumptions
Every email we send is backed by real data -- SEC filings, earnings transcripts, job postings, technographics. We never guess what a prospect cares about. We find proof.
Safety Over Speed
We would rather send 100 great emails than 10,000 mediocre ones. Canary rollouts, safety gates, and policy checks ensure nothing leaves the system unless it meets our quality bar.
Quality Over Volume
Spray-and-pray is dead. We measure success by reply rates and pipeline created, not emails sent. Every prospect deserves outreach that respects their time and intelligence.
Software engineering discipline, applied to sales
Most sales tools treat email sends like fire-and-forget API calls. We treat them like production deployments -- with rollback plans, canary testing, and safety gates.
Canary Rollout
New email strategies are tested on a small slice of traffic first. If reply rates dip, the system automatically rolls back -- just like a production deployment.
Safety Gates
Five independent checks verify every email before it sends: domain health, content quality, policy compliance, deliverability score, and rate limits.
CI Governance
Architectural decisions are enforced at build time. Protected paths require ADR references. Events must be registered. Safety invariants are proven, not assumed.
Join the evidence-first revolution
Stop guessing what your prospects care about. Let CortexSales find the proof and write the email.
