Most B2B teams filter prospects by industry and headcount, then wonder why half the list never responds. The strongest signal a company is ready to spend money isn't on their about page. It's on their careers page.
One open requisition means a team is short-staffed. Three open reqs for the same function means someone signed off on headcount and budget this quarter. That's the moment to show up, not after they've hired and solved the gap themselves. If you sell to sales or marketing teams, a company posting for an SDR manager, a demand gen lead, and a marketing ops hire inside the same 30-day window is telling you, in public, that they just got funded to fix the exact problem your product solves.
The timing matters more than the title. A single req for a mid-level marketer posted six months ago and never refreshed is stale. A fresh posting, less than two weeks old, for a role your product directly supports, is the account to call this week, not next quarter.
Recruiting firms chase the req the day it posts, when every other agency in the city is doing the same thing. The better play is watching for the second and third req in the same department within 30 days. That's a hiring spree, not a one-off backfill, and it means the client needs a partner who can fill more than one seat, not just the first one that was posted. A single open role tells you a company has a vacancy. Three open roles in sales ops within a month tells you they have a plan, a timeline, and a hiring manager who's about to get frustrated with slow candidate flow. Call them in week two, after the initial flood of unqualified applicants, not day one when they still think they'll fill it themselves.
A job posting pulled down fast usually means one of two things: they filled it internally, or they panicked and paused the search. Either way, don't delete that contact. Set a 60-day follow-up. Fast-filled roles often get re-opened when the hire doesn't work out, especially for sales and marketing leadership positions where a 90-day fit assessment is common. The hiring manager remembers whoever reached out the first time, even if that first conversation went nowhere, and a second outreach after a quiet role resurfaces lands differently than a cold one.
A job posting alone is weak. A job posting plus a recent funding round plus a new VP in the function is strong. Think of it as a short checklist: open req in the target function, leadership change in that function within the last 90 days, and a funding or expansion event in the last two quarters. Hit two of three and the account moves to the top of the list. Hit all three and you're talking to a company that has budget, a mandate, and a fresh executive who wants quick wins.
Combining three signals cuts your list by 90% and doubles the quality of who's left. This is the part manual prospecting can't do at scale, because cross-referencing three data sources for 500 accounts a week is a full-time job on its own, and most teams don't have anyone whose job that actually is. Spreadsheets and manual LinkedIn searches work for ten accounts. They fall apart at a hundred.
A hiring spree for warehouse staff means nothing to a company selling sales software. Match the function on the req to the function your product actually serves. A pile of signals on the wrong department is just noise with extra steps, and it will bury the three accounts that actually matter under forty that don't. Before you build a signal-based list, write down the two or three job titles that, if posted, mean your buyer is in motion. Everything else is a distraction.
Agent360's buying signals detection watches job postings, funding events, and hiring patterns across your target accounts and surfaces the ones stacking up, so your list is built from timing, not just firmographics. Pair that with AI prospecting that finds the right buyer inside each account, and multi-channel outreach that reaches them on LinkedIn, email, and phone without you managing three separate tools. You can see how the full workflow runs end to end on how it works .
How many open reqs count as a real signal? Two or more open roles in the same department within 30 days is a reliable threshold. One role could be a routine backfill; two or more usually means budget was approved for growth, not replacement.
Should I still prospect companies with no open reqs? Yes, but treat them as a lower-priority list. Signal-based accounts convert faster, but a pipeline built only on active hiring will run thin. Use broader lead gen to keep volume steady while signals drive your top priority accounts.
Where do I find job posting signals without paying for a separate tool? Agent360 tracks them as part of the core platform, so you're not stitching together a job board scraper and a CRM by hand. Details on pricing and what's included are on the FAQ page .
