You can get buying signals without Clay by tracking each signal at its source: job boards for hiring, company websites and news for leadership and product changes, technographic tools for stack changes, funding databases for rounds, website visitor tools for your own traffic, and LinkedIn for engagement with your posts. Clay's value was putting those sources in one table. Without it, the work is choosing 2 or 3 signals that predict a purchase for your offer, pulling them on a schedule, and scoring them in one place, usually a CRM or a spreadsheet.
Start with the signal, not the tool
Most failed signal setups track everything. A founder in r/gtmengineering who asked for help after leaving Clay described the problem well: hiring and funding alerts are easy to get but too generic, and the useful signals are specific to the pain you solve. For a sales consultancy, that means leadership changes, rapid sales hiring, a CRM migration, new pricing, a new market, or a company trying to move past founder-led sales.
Write one sentence for each signal before you build anything: "When a company does X, it is more likely to need us within 90 days because Y." If you can't finish the sentence, the signal will only add noise to your list.
Six signals and where to get them
| Signal | What it suggests | Where to get it without Clay |
|---|---|---|
| Job postings | Budget and a gap the company is trying to fill | LinkedIn and Indeed job scrapers on Apify, job and tech-stack data from TheirStack |
| Leadership changes | A new leader reviewing vendors in the first 90 days | LinkedIn job-change alerts in Sales Navigator, enrichment APIs with job-change webhooks |
| Tech stack changes | A migration, a new tool to integrate with, or a competitor to displace | BuiltWith, TheirStack, Techleads.fyi |
| Funding rounds | New budget and hiring plans | Crunchbase, news alerts, press releases |
| Website visits | A company already researching you | Visitor identification tools such as RB2B or Factors |
| Engagement with your content | Familiarity with you and your topic | Likes and comments on your LinkedIn posts, exported manually or with a scraper |
Hiring signals
Job posts are the easiest signal to collect and the easiest to misuse. A company hiring its first SDRs is a better fit for an outbound agency than one hiring its fortieth. Filter by role, seniority and count: "first sales hire", "head of growth", or three or more SDR roles in 30 days. TheirStack finds companies from job postings and tech-stack mentions and has an API, so you can push results straight into a sheet or CRM. Apify actors can scrape LinkedIn and Indeed jobs on a schedule.
Leadership changes
A new VP of Sales or CMO usually reviews tools and agencies in their first quarter. Sales Navigator flags job changes on saved leads. If you already pay for a person-enrichment API, many offer job-change monitoring that fires a webhook when a tracked contact moves. One r/gtmengineering user described exactly this: a job-change webhook updates the CRM record and posts to Slack so reps can act the same day.
Tech stack changes
A company adding HubSpot, dropping a competitor, or installing a tool you integrate with is a timely reason to reach out. Technographic tools read website code and other public sources to show what a company runs. Our guide on how to find companies by tech stack walks through the main sources and their limits.
Company news and changes
Product launches, pricing changes, new markets and partnerships are the signals that Clay's AI research columns used to pick up. Without Clay, you can use a web monitoring service. One r/gtmengineering user described giving each target company its own monitor in Parallel's web monitoring product, then using an AI agent to decide whether each change matters against their playbook. A simpler version is a weekly scrape of each target's pricing, careers and press pages with Firecrawl, comparing the text with the previous week.
Your own first-party signals
The strongest signals are about you: a target account visiting your pricing page, a prospect commenting on your LinkedIn post, a former customer's champion joining a new company. They cost little to collect and convert better than third-party data because the prospect already knows who you are.
Three ways to run it without Clay
| Setup | How it works | Trade-off |
|---|---|---|
| Point tools plus your CRM | Each signal tool pushes into HubSpot or a sheet; a score field adds them up | Least maintenance; you pay for each tool |
| n8n or a scheduler plus scrapers | Scheduled workflows pull jobs, pages and news, then route to the CRM | Cheap to run; breaks when a site or actor changes |
| Claude Code plus APIs | Scripts pull and score signals on demand or on a schedule | Flexible; needs someone technical and careful checking of AI output |
Two warnings from people who built the second and third setups. First, maintenance is the hidden cost: one user described an n8n run history full of timeout errors after a target site changed its page structure. Second, language models will invent signals and email addresses if you let them write data instead of reading it. Have scripts fetch facts from a source and store the source URL with each signal, so a person can check it before outreach. If you plan to run this research with a coding agent, our piece on whether Claude Code can replace Clay covers the setup and its upkeep.
Scoring signals so reps act on them
- Give each signal a weight and an expiry. A pricing-page visit might be worth 30 points for 14 days; a funding round 15 points for 90 days.
- Add fit before timing. A strong signal on a company outside your ICP is still a bad lead.
- Set one threshold. Accounts above it go to a rep or a sequence this week. Everything else waits.
- Write the signal into the first line. "Saw you're hiring your first two AEs" earns a reply. "Hope you're well" doesn't.
When Clay is still the easier answer
If you track five or more signal types across thousands of accounts and change them often, Clay's signal tracking on the Launch plan ($185 a month) may cost less than the time spent maintaining scrapers. Our breakdown of whether Clay is still worth it after the pricing change has the numbers, and cheaper alternatives to Clay covers the tools that replace its enrichment side.
Signals only pay off when someone acts on them quickly with a relevant message. If you want the list, the signals and the outreach handled as one system, that is the work KomsGro's B2B cold outbound agency does.
