CosGen AI SDR

CosGen Agent is a B2B sales intelligence platform that automates the full LinkedIn outreach lifecycle — from prospect research to booked meetings — with the human always in control. At its core sits a powerful Chrome Extension that lets sales reps push any LinkedIn profile directly into an AI-powered outreach campaign with a single click, without ever leaving LinkedIn. The extension detects the profile you're viewing, pre-fills all the details, and sends it straight to your chosen agent — who then researches, warms up, and engages the prospect directly on LinkedIn, on your behalf, while you stay informed and in control at every step. No copy-pasting URLs. No tab switching. No manual data entry. Just one click, and your CosGen Agent takes it from there. The problem CosGen Agent solves is one that every B2B sales team knows intimately. Relationships close deals, but building them properly at scale is impossible with human effort alone. Sales reps face a constant tension between quality and quantity — either they invest deeply in a small number of prospects and miss pipeline numbers, or they blast high-volume automated messages that feel robotic, get ignored, and quietly damage the company's reputation on LinkedIn. There has never been a credible middle path. Cosgen AI SDR is that middle path. It gives sales teams the ability to operate at volume without sacrificing the quality, context, and human feel that actually converts prospects into customers. The key distinction is that this is not autonomous AI running unchecked — it is AI working in close collaboration with humans, taking real actions on LinkedIn while the human retains full visibility, oversight, and the ability to intervene at any moment. The platform is built around a core belief: the best customers are not acquired, they are earned. Every interaction a prospect has with your brand on LinkedIn — every comment on their post, every connection request, every opening message — either builds trust or erodes it. CosGen Agent is engineered exclusively to build it, at a consistency and scale that no human team could sustain alone. It thinks like a researcher, engages like a relationship builder, and communicates like your best sales rep — except it works continuously, scales without hiring, and never has an off day. And critically, every action it takes is visible to you, reviewable by you, and stoppable by you. This is human-in-the-loop AI in its truest form — not a black box running in the background, but a transparent, controllable agent working alongside your team in real time. At the heart of the user experience is the Chrome Extension — a lightweight, deeply intelligent browser tool that transforms how sales reps interact with LinkedIn on a daily basis. The extension embeds seamlessly into the LinkedIn interface, adding a persistent floating action button — a lightning bolt icon — that sits quietly on every LinkedIn page, always accessible, never intrusive. When a sales rep lands on a prospect's profile and sees an opportunity, they click the lightning bolt. A sleek slide-out panel appears from the side of the screen without taking them away from the page. The prospect's name, profile photo, and LinkedIn URL are already populated — the extension has detected the page and extracted the data automatically. The rep selects which AI agent or campaign should handle this lead, optionally adds a short sourcing note for context — something like "Met at SaaStr" or "Commented on our funding post" — and hits push. The entire interaction takes under ten seconds. From that moment, the AI agent takes over execution — acting directly on LinkedIn on the rep's behalf, while the rep retains full visibility into every action taken. The Chrome Extension is built on Chrome's Manifest V3 platform — the latest and most secure standard for browser extensions — ensuring compatibility with current and future versions of Chrome, enterprise policy support, and alignment with Google's performance and security requirements. All API communication between the extension and the Cosgen backend is proxied through a background service worker running in the extension's isolated context. This architecture cleanly bypasses the CORS restrictions that would otherwise block direct calls from a content script to an external server, ensuring fast and reliable communication regardless of which LinkedIn page the user is on. Authentication inside the extension is designed for both security and convenience. Users can sign in via standard email and password authentication checked directly against the Cosgen backend, or via an email-based one-time password for passwordless access. Once authenticated, the session persists securely across browser sessions using Chrome's local storage API — meaning reps are never interrupted mid-workflow by unexpected logouts. Signing out clears the session entirely and returns the interface to the login screen. The lead capture popup — accessible from the Chrome toolbar at any time — is the command centre of the extension. Its most important feature is automatic profile detection. If the user's active tab is a LinkedIn profile page, the extension detects this instantly and pre-fills the profile URL without any manual input. The agent selector allows the rep to choose which AI agent or LinkedIn-connected account should handle the lead, and the extension remembers the last selection — so reps working a specific campaign throughout the day do not need to reselect it on every push. The optional lead sourcing notes field is a small but strategically powerful feature: any context added here is passed directly to the AI agent and incorporated into its research and outreach planning. A note like "Referred by James Chen" or "Downloaded our whitepaper last week" gives the agent the additional signal it needs to craft an opening that feels genuinely informed rather than generically personalised. Duplicate detection runs automatically on every push — if…
