Description
AI-powered sales agent that researches prospects, warms them up with authentic LinkedIn engagement, and starts real conversations. 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 a profile URL already exists in the pipeline, the backend returns a 409 conflict response which the extension catches and surfaces to the user immediately, keeping the pipeline clean without any manual deduplication. A connection status indicator — a simple green or red dot in the extension UI — shows the live health of the Cosgen backend at all times, so reps know before attempting a push whether the system is reachable. The content script layer of the extension is where the experience becomes truly frictionless. Rather than requiring users to open a popup or leave LinkedIn, the content script embeds the CosGen Agent interface directly into the LinkedIn page itself. The floating action button renders on every LinkedIn page — profile pages, feed, search results, messaging — and opens the slide-out panel inline when clicked. The panel is designed to feel native to LinkedIn's own interface: clean, fast, and non-disruptive. When opened on a profile page, it automatically extracts the prospect's full name, profile photograph, and canonical URL from the page content and populates the form before the user has read a single field. When opened on a non-profile page — such as the LinkedIn feed or a search results page — a manual URL input field is available as a fallback, allowing the rep to paste any LinkedIn profile URL and push it directly. The extension is fully aware of LinkedIn's single-page application architecture, which means it monitors URL changes that happen without full page reloads and resets the panel state accordingly — ensuring the detected profile always matches the page the user is currently viewing, with no risk of pushing stale or mismatched data. The panel also closes naturally when the user clicks anywhere outside it, keeping the browsing experience clean. For teams operating across multiple environments — cloud-hosted, self-hosted, or staging — the extension's settings panel allows the backend URL to be configured freely and saved with immediate effect, without requiring reinstallation or any changes to the extension itself. Once a lead is pushed through the Chrome Extension, the CosGen Agent backend pipeline takes over. The lead enters a structured agent workflow designed to move it through every stage of the outreach journey — acting directly on LinkedIn on the user's behalf, with the human in the loop at every meaningful decision point. The Manager Agent is the orchestrator of this pipeline. It receives the incoming lead, triggers a deep enrichment process against the prospect's LinkedIn profile, and builds a fully personalised outreach plan based on the prospect's role, industry, recent activity, content engagement patterns, and any sourcing context provided by the rep. The Manager Agent is the sole interface with LinkedIn via the Unipile integration layer — every action taken on LinkedIn, from profile views to messages sent, flows through this agent. This centralised control ensures that all LinkedIn activity is coordinated, logged, and fully visible to the human user through the platform dashboard. Sub-agents operate as specialised intelligence modules within the pipeline, each responsible for a specific layer of research or content generation. The Profile Research Agent performs deep analysis of the prospect's LinkedIn presence — their posts, engagement patterns, career trajectory, stated priorities, and shared connections — and produces a rich research brief that informs every subsequent touchpoint. The Message Drafting Agent uses this research brief, combined with the user's configured persona, knowledge base, and conversion goals, to generate outreach messages that are grounded in real context and read like they were written by a thoughtful human rep. The Engagement Agent identifies the prospect's recent LinkedIn posts and generates contextually relevant comments designed to build genuine familiarity before any direct outreach begins. All of these sub-agents feed their outputs back to the Manager Agent, which reviews, sequences, and executes each action directly on LinkedIn at the right moment. The outreach sequence itself is structured as a deliberate, multi-stage warm-up pipeline. Before a connection request is ever sent, the agent engages with the prospect's content — liking posts, leaving considered and contextually relevant comments — to establish a visible, positive presence in the prospect's feed. This warm-up phase is not performative. It is designed to make the prospect genuinely aware of your brand before any direct communication arrives, so that when the connection request lands, it does not feel like an interruption — it feels like a natural next step in an already-forming relationship. Once sufficient warm-up engagement has occurred, the agent sends a personalised connection request directly through LinkedIn. After the connection is accepted, the agent initiates direct messaging with an opening that references the shared context — the content interactions, any mutual connections, the prospect's recent announcements or activity — creating a conversation that feels warm and informed from the very first line. Throughout every stage of this pipeline, the human user remains in the loop. The platform dashboard surfaces every action the agent has taken, every message it has sent, and every response it has received — in real time. Reps can read the full conversation thread at any point, adjust the agent's next planned action, pause outreach for a specific lead, or take over the conversation manually with a single click. This handoff capability is one of the most important design decisions in the platform: the agent handles the research, the warm-up, and the opening, and the human steps in at the moment of peak readiness — when the prospect is warm, engaged, and genuinely open to a conversation. The AI does the work that doesn't require a human. The human does the work that only a human can do. Account safety is a first-class architectural concern throughout the entire system. Daily action limits cap the total number of profile views, content engagements, connection requests, and messages the agent executes each day — keeping activity within the natural range of a human sales rep and well within LinkedIn's acceptable use boundaries. Randomised timing between actions eliminates the mechanical regularity that LinkedIn's systems identify as automated behaviour. Configurable sleep windows allow the agent to be paused outside business hours or during periods when the user is themselves active on LinkedIn, preventing the simultaneous human-and-bot activity patterns that can trigger account reviews. These safety mechanisms are not optional settings — they are core to how the agent operates, ensuring that the LinkedIn account remains healthy, credible, and compliant over the long term. CosGen Agent is built for B2B sales teams at startups and scaling companies who understand that pipeline quality matters as much as pipeline volume. It is for founders doing their own sales who cannot afford to research and warm up every prospect manually but refuse to send impersonal bulk messages that reflect poorly on their brand. It is for sales leaders who want their reps spending time on real conversations and closing, not on research and cold outreach. It is for anyone who has looked at their LinkedIn outreach results and known that there has to be a better way — one that combines the intelligence and relationship instincts of a great human rep with the scale and consistency that only AI can provide. The Chrome Extension is the on-ramp. The AI agent pipeline is the engine. The pipeline dashboard is the control room. Together, they give sales teams something that has never existed before: the ability to build real relationships at real scale, with a human always in control, and an AI always doing the heavy lifting. One click on LinkedIn. Your agent takes action. You stay in the loop. Meetings get booked. CosGen Agent is built and operated by Cosnet Global Solutions Private Limited. © 2026 All rights reserved.
