AiSDR is an AI sales development rep that runs outbound across email and LinkedIn. It researches a prospect, writes a personalized first touch, sends the sequence, and replies to responses on its own. A dedicated GTM engineer tunes each campaign, so a small team can cover far more accounts than headcount alone. It pulls lead data and intent signals, then drafts each message from hundreds of research sources for context. Alongside the sending it handles domain setup, inbox warmup, voice and video notes, and native CRM sync. Pricing is monthly with seats and lead credits bundled, which makes it an easy motion to switch on. It belongs to the AI-SDR category, and that is precisely where Nebor's view diverges. The product is something you rent and turn on, a managed agent that books meetings while it runs. When the contract ends, the data, the routing, and the institutional knowledge leave with the vendor rather than staying behind as an asset. Nebor's position is to own the system instead of renting a worker. The better build keeps lead data and routing inside accounts the client controls, in a Clay-centered stack that survives any vendor switch and feeds more than one channel. An AI sender can be a tenant there, not the engine for the whole motion.
