Clodura.AI

Clodura.AI — GenAI Go-to-Market Platform. From Database to Deal Closure. Clodura.AI is a Series A funded GenAI Go-to-Market platform trusted by 73,000+ sales professionals worldwide. It is the only platform that unifies your complete revenue workflow — data, intelligence, AI-powered outreach, calling, and deliverability — without requiring a multi-tool stack. Most GTM teams are paying for four to six tools that don't talk to each other. Clodura.AI was built to replace that stack with one platform that runs the full motion: find the right contacts, understand the buying context, reach out with messages that earn replies, and track outcomes — all in one place. The Database 600M+ verified B2B contacts and 50M+ company profiles with deep organizational intelligence. Emails and mobile numbers verified in real time through integrations with 50+ email providers and 20+ dialer networks — so your team is always working with data that is accurate at the moment of use, not at the moment of export. Email Verifier Every contact unlocked inside Clodura is verified in real time before it reaches the user. Clodura.AI's Email Verifier extends that same engine to externally sourced lists — CRM exports, trade show leads, LinkedIn contacts, purchased databases — without requiring a separate subscription or tool. Two verification tiers: Standard: Covers syntax checks, domain validation, and SMTP verification. Suited for warm databases and existing CRM records. Deep: Adds catch-all domain detection and identification of SEG-protected inboxes (Proofpoint, Mimecast, Barracuda). Built for cold outreach into enterprise accounts where deliverability risk is highest. Single email verification returns results inline. Bulk CSV uploads up to 100MB run through a High Volume pipeline. Both tiers run on existing Clodura credits — no separate invoice, no third-party account to manage. Atlas — Agentic SDR Atlas is Clodura.AI's Agentic SDR. It does not send templates. It writes a completely original email from scratch for every prospect — based on individual research across three intelligence layers. Seller Intelligence: Atlas analyzes your website and offer to build a deep understanding of your value proposition and competitive position before writing a single word. Buyer Company Intelligence: For every target account, Atlas evaluates funding signals, tech stack, hiring patterns, recent news, and leadership changes — identifying genuine buying readiness rather than demographic fit alone. The EQ Engine: Atlas profiles each individual prospect at the psychographic level: negotiation style, communication preferences, technology adoption profile, and career trajectory. A CMO six months into a new role has different priorities than one with five years of tenure. Atlas identifies which is which — and writes accordingly. The training behind Atlas is Atlas University — a four-semester curriculum built on 10 million successful outbound emails, 5 million subject lines, and 100,000+ A/B campaigns. Seven proven sales frameworks (Sandler, Challenger, SPIN, SNAP, Straight Line, and more) are matched to each prospect's psychographic profile at 95% accuracy. Every Atlas sequence follows a structured five-phase cadence: Hook → Value → Proof → Bump → Breakup. Every sequence is reviewed by a human before the full campaign goes live. Your team sees sample emails per prospect, can edit or regenerate any message, and controls what goes out — before a single email reaches an inbox. The results Atlas campaigns consistently deliver: Open rates: 40%+ (industry average: below 10%) Reply rates: 4%+ (industry average: 0.5% — an 8X improvement) 95% Primary inbox placement Every email original — written from scratch per prospect CallPilot — Integrated Dialer CallPilot is Clodura.AI's built-in calling layer. Make calls directly from the platform with local presence dialing, call recording, and activity logging — without switching to a separate dialer. Multi-channel outreach managed in one place, with full visibility on every touchpoint. Deliverability Suite Inbox health is engineered into the platform, not bolted on. Before any campaign goes live: Spam Score — every email is analyzed against dozens of spam filter algorithms and flagged for correction before sending Inbox Placement Testing — campaigns are tested against 250,000+ diverse test inboxes spanning every major email provider and enterprise security configuration Inbox Warmup — domain and mailbox warmup built in to protect sender reputation at scale Exact placement is verified — Primary, Promotions, or Spam — and only campaigns achieving high Primary placement rates proceed to launch. Clodura.AI consistently achieves 95% Primary inbox placement. Pricing and Scale Credit-based pricing with unlimited users. No per-seat tax on team growth. Whether you're a founder running outbound yourself or a RevOps team standardizing a 50-person sales org, the pricing model scales without penalizing headcount. Why GTM Teams Switch to Clodura.AI The typical sales stack costs $15,000–$40,000+ per year across separate tools for data, enrichment, sequencing, calling, and deliverability. Each tool requires its own login, its own integration, its own contract, and its own failure mode. Clodura.AI consolidates that motion into one platform — with a single data layer, a single outreach system, and a single source of truth for pipeline activity. From database to deal closure. All in one platform.
