What Celestic does
Celestic is a privately held B2B client-acquisition service that operates the Celestic Business Accelerator™, an AI-driven cold-email outreach platform designed to deliver 5-10+ qualified B2B clients per month for its SMB and mid-market customers. The company's core technology combines an AI personalization engine—which scrapes prospect websites, LinkedIn profiles, and recent news to generate unique email openers with dynamic variables for tech stack, funding events, and job postings—with a hardened multi-domain email infrastructure (40+ warmed inboxes, SPF/DKIM/DMARC, automated warmup, real-time deliverability monitoring) and a human-reviewed QA layer. Deliverability is protected through six-touch, multi-week sequences (Day 1, 15, 30, 60, 90, 120) with multivariate A/B testing across subject lines, CTAs, send times, and copy tone. The platform is supported by an integrated tech stack that includes HubSpot, Outreach, Apollo, Smartlead, Lemlist, Instantly, Mailchimp, Klaviyo, and others for enrichment, sending, and marketing automation.
Celestic monetizes through two pricing structures: a fixed monthly subscription retainer delivering 5-10+ qualified B2B clients per month with no long-term contracts, and a capped Pay-Per-Lead option for ROI-sensitive clients with tight CAC/payback constraints. Customer acquisition runs exclusively through a sales-led direct motion—a complimentary 15-minute consultation booking funnel—augmented by content marketing (case studies, ROI calculator, FAQs) targeting verticals including marketing/advertising agencies and professional services (accounting, ERP). The company claims to have served 34-50+ businesses with documented wins including 24 new clients and $485K+ forecasted revenue for a Colorado marketing agency, and 16 qualified opportunities from 7,359 contacts for a Geneva-based Swiss accounting firm. Geographically, Celestic operates from a Dubai Free Zone entity (Celestic LLC-FZ) and serves clients across North America, Europe, and the Middle East, with multilingual campaign execution demonstrated in French.
The business is bootstrapped—co-founded and operated by Marc Diez and Bernat Diez as Managing Partners—with no external funding, no disclosed revenue, and a headcount of approximately 11 employees. The company is actively operating and accepting new clients, with distribution built entirely on direct sales rather than channel partners or resellers.
