Pick the ones that fit your workflow — there's no "right" mix.** Every source lives on the List detail page under **+ Add source**. You can add, edit, pause, or remove sources at any time. ## Search criteria The most common source. You describe your ideal customer — job titles, location, industry, company size — and Guhan searches its data pipelines every day for people matching. Add each title as a chip. Guhan auto-generates variants so you don't have to list every wording: * You type: **VP of Sales** * Guhan matches: Vice President Sales, SVP Sales, Senior Vice President Sales, Head of Revenue, Head of Sales… You can see and edit the auto-variants below the input. Autocomplete-backed. Type "San Francisco" → pick from suggestions. Multi-select with OR logic. Cities, states, countries, regions all work. "United States" catches everyone in the US; "New York" catches NY-metro only. LinkedIn's official industry taxonomy. Pick one or many. "SaaS" isn't a LinkedIn industry — it's a subset of "Software Development". Use "Software Development" and let a signal or your headcount range narrow further. Headcount slider. Leave both ends blank = no cap. Common ranges: * **1–10** — pre-seed startups * **11–50** — seed to Series A * **51–200** — post-Series-A scaleups * **201–1000** — mid-market * **1001+** — enterprise If you sell to a specific geography (e.g., US companies only), set HQ = United States. This is stricter than person-location — the *company* has to be HQ'd there, not just the person. Search criteria alone is enough to fill a List. If you don't add a buying-signal source on top, Guhan runs a plain daily search for people matching your criteria. ## Buying signals Only add people when a triggering event fires. Signals turn a broad audience into a "reach out to them right now" moment. Pick from six signal types on the WHEN panel: * 💰 **Funding raised recently** — companies that just raised a round * 📈 **They're hiring** — companies posting roles in a department you care about * 👔 **New leadership joined** — companies where an exec or director joined recently * 🎯 **Engaged with a competitor's post** — people who liked or commented on your named competitors' posts * 📢 **Posted about specific keywords** — people writing (or engaging with) posts matching your keywords * 🎁 **Engaged with a specific post URL** — people who reacted to or commented on exact post URLs you paste in Each signal has its own config (recency window, keywords, competitor URLs, etc.). Every signal Guhan supports, with configuration options and example openers. ## Competitor engagement A special case of the "posts" signals — you paste your competitors' LinkedIn URLs and Guhan watches every one of their posts, landing the people who engage. * **Company URLs** watch every employee's posts from that company. * **Individual profile URLs** watch a specific person (e.g., a competitor CEO or head of marketing). This is the highest-intent signal Guhan supports — someone commenting on your competitor is actively evaluating your category. Details + example openers. ## Copy from another List Duplicate the current members of an existing List into a new one. Useful when you want to: * **A/B test** two sequences against the same audience * **Segment** further — take an "All US SaaS" List and copy into a smaller "US SaaS · Enterprise" List * **Reactivate** — copy a stale List into a new one with a fresh sequence The copy is a snapshot at the moment you click Copy. Future prospects landing in the source List don't auto-flow to the copy. ## CSV upload Upload a CSV of prospects you already have. Guhan enriches them from LinkedIn and treats them like any other prospect. **Minimum columns:** * `linkedin_url` OR `email` (at least one) * `name` (optional but recommended) **Optional columns:** * `email` — pre-populates so Guhan doesn't need to reveal it (saves credits) * `company_name`, `title`, `phone` — anything else you have Guhan enriches every uploaded row from LinkedIn — so even a bare CSV with 500 LinkedIn URLs becomes 500 fully-profiled prospects with fit tiers, research briefs, and current-role data. ## Manual add Paste a LinkedIn URL or search by name to add one prospect at a time. Best for: * **Warm leads** — someone you already know is a fit; skip discovery entirely * **Referrals** — a colleague forwarded you a lead * **Testing** — add yourself to a List before launching to confirm the messaging looks right Guhan enriches from LinkedIn on add, so a manually-added prospect behaves identically to a discovery-sourced one downstream. ## Multiple sources on one List You can add as many sources as you want to the same List. Every source runs independently — Guhan de-dupes so no prospect gets added twice. **Example:** an "Enterprise Sales Leaders" List might have: * Search criteria source: VP Sales at 500+ headcount SaaS companies * Funding signal source: same criteria + only when funding announced in last 90 days * Competitor engagement source: watch two competitor company URLs Prospects who match multiple sources are added once and tagged with all matching sources — the message can reference whichever one is most relevant. ## Related Full reference for every signal, with configuration and openers.
