Buying signals are observable events that suggest a company may be about to buy something like what you sell: a new job post, a funding round, a public post about a problem, or a change in its official company records. They don't prove intent on their own, but they tell you who to talk to first and give you a genuine reason to get in touch. Sell into those moments and outbound stops feeling like shouting into the void.
If you're a founder doing your own sales, you don't have time to work a list of 2,000 companies in alphabetical order. You need the ten that are most likely to say yes this week. That's what buying signals are for.
What counts as a buying signal?
A buying signal is anything a company does, in public, that changes the odds it needs your product soon. The best ones share three traits:
- Dated. You know when it happened, so you know if it's still fresh.
- Verifiable. You can link to it. No guessing, no "our model thinks".
- Relevant to you. It connects to the problem you solve. A new office is a signal for a desk-booking tool, not for a payroll app.
In sales training you'll also hear "buying signals" used for things a prospect says on a call ("what does onboarding look like?"). That matters too, but this guide is about the signals you can spot before the first conversation: the ones that decide who you reach out to at all.
The main types of buying signals (with examples)
1. Hiring signals: new job posts
A job post is a company telling the world what it's about to invest in. If a business posts for its first sales hire, its first RevOps person or a "Head of Growth", it's about to build processes and buy tools.
Examples:
- A seed-stage startup posting its first two account executive roles: likely to need sales tooling, data and onboarding support.
- A company hiring a data engineer whose job description names the warehouse they're moving to: a migration is coming.
- A business advertising for a finance lead for the first time: expect new finance software decisions.
Read the job description, not just the title. The tools, problems and goals listed are your opening line.
2. Funding and news
Fresh money usually means new plans, new hires and new budgets. Funding announcements, acquisitions, new market launches, big partnerships and leadership changes all count.
The trap is reacting to the headline. Everyone sees the press release. "Congrats on the raise!" is the most common cold email on the internet. Use the news to decide who, then use the detail (what they said they'll spend it on) to decide what to say. We go deeper on this in why funding rounds are the best time to reach out.
3. Public posts on X
Founders and operators talk about their problems in public. A post saying "our reporting is a mess" or "anyone recommend a tool for X?" is about as close to a raised hand as you'll get. Public X posts are useful because they're in the person's own words, which tells you exactly how to frame your message.
Treat these with care. Reply helpfully or reference the post honestly; don't pretend you stumbled across their company by chance.
4. UK Companies House changes
If you sell to UK businesses, the official register is a goldmine that most people ignore. Companies House makes its public company data available free of charge, including officers, filing history and company status.
Useful changes to watch:
- New directors or officers. A new leader often reviews suppliers.
- New share allotments. UK limited companies must file a return of allotment of shares (SH01) within one month of allotting shares, so a funding round can show up on the register even if it was never announced.
- Registered office moves. Often a sign of growth or restructuring.
- New companies incorporated in your niche. Brand-new businesses need everything.
5. First-party signals
Pricing page visits, trial sign-ups that stall, replies to your newsletter. If you have these, use them; they're the strongest of all. Most early-stage founders don't have enough traffic for these to fill a pipeline, which is why external signals matter so much.
Strong vs weak buying signals
Not every signal deserves a message. A rough way to rank them:
| Stronger | Weaker |
|---|---|
| Directly tied to the problem you solve | Loosely related ("they're growing") |
| Happened in the last few days or weeks | Happened months ago |
| Names a person you can contact | Only a company name |
| Several signals at once | A single isolated event |
| Matches your ICP closely | Outside your usual customer profile |
The last row matters most. A brilliant signal from a company that will never buy from you is still a waste of time. Signals tell you when; your ideal customer profile tells you who. If you haven't nailed that yet, start with our guide to defining your ICP in 15 minutes.
Stacking is where it gets good. A company that raised, then posted three sales roles, then appointed a new commercial director is shouting. One signal is a hint; two or three together are a reason to drop what you're doing.
How to act on a buying signal
Spotting signals is half the job. Here's a simple, repeatable way to use them.
Step 1: Check fit first
Before writing anything, ask: is this company inside my ICP? Right size, right sector, right geography, right model? If not, skip it, however juicy the signal.
Step 2: Find the right person
Match the signal to the owner of the problem. A sales hiring spree points to the head of sales or the founder. A finance hire points to the CFO or COO. If you can only find a generic inbox, the signal is less useful.
Step 3: Write the "why now" line
This is one sentence that connects the signal to your product. It's the whole reason the email exists.
- Weak: "Saw you raised. Would love to chat."
- Better: "Saw you're hiring your first two AEs. Teams at that stage usually hit [specific problem] within a couple of months; we fix that by [specific outcome]."
If you can't write a sharp why-now line, the signal probably isn't relevant enough.
Step 4: Keep it short and send it fast
Signals go stale. A message referencing a job post that closed weeks ago looks lazy. Aim to act within days, not weeks. Three or four sentences, one clear question, no attachments.
Step 5: Log what happens
Did they reply? Book a call? Ignore you? Over time you'll learn which signals actually turn into revenue for your product, and you can stop chasing the ones that don't.
Common mistakes founders make with buying signals
- Chasing volume. Fifty generic signals a day is noise. Ten well-matched ones you actually act on is a pipeline.
- Leading with the signal instead of the problem. The signal is your reason for reaching out, not your pitch.
- Ignoring fit. See above. Fit first, timing second.
- Doing it all by hand. Checking job boards, news, X and Companies House every morning is a part-time job. It works for a week, then something more urgent wins.
- Never refining. The signals that work for your first ten customers might not work for the next fifty. Review what converts.
Doing this without spending your mornings on it
You can absolutely run a buying-signal process with bookmarks, Google Alerts and a spreadsheet. Many founders start that way. The problem is consistency: the day you skip is the day the perfect lead shows up.
That's the job Outrun does. You set your ICP once (or describe your ideal customer in plain English and let AI turn it into fields), and every weekday morning at 7am in your timezone you get up to 5, 10 or 20 leads a day (or 10 per seat on Team, depending on your plan) showing a fresh buying signal, in your inbox (or Slack/Telegram on Growth and up). Each one comes with a short why-now line and a contact. Signals come from new job posts, funding and news, public posts on X and UK Companies House changes.

FAQ
What are buying signals in sales?
Buying signals are observable events or behaviours that suggest a company or person may be ready to buy. Before first contact, they include job posts, funding news, public posts about a problem and changes in official company records. During a sales conversation, they include questions about pricing, onboarding or timelines.
What are examples of buying signals?
Common examples include a company hiring for a role related to your product, announcing a funding round, appointing a new leader, posting publicly about a problem you solve, or filing changes such as new directors or share allotments at Companies House.
Are buying signals the same as intent data?
They overlap. Intent data usually refers to research behaviour, such as which topics a company is reading about online. Buying signals is a broader term that includes discrete public events like hiring, funding and leadership changes, which are dated and easy to verify.
How quickly should I act on a buying signal?
As soon as you can do it well. Signals lose relevance as they age, so aim to reach out within days of spotting one. A thoughtful message next week beats a generic one today, but a thoughtful message today beats both.
How many buying-signal leads should a founder work each day?
Enough that you can personalise every message. For most founders doing their own sales, that's somewhere between five and twenty-five leads a day, depending on how much time you give to outbound.
