Over the last two years I've watched the outbound stack get more complicated, not less.
More tools. More signals. More dashboards.
And most teams still can't answer the basic question: "who should we call today and why?"
So I figured I'd just write about it.
If I were a founder or a C-suite exec at a B2B SaaS company right now, this is the workflow I'd send my sales team.
It goes beyond blasting an email list.
Here's what it tracks and how it fits together.

- Track five things, not one.
Off-site buyer intent.
On-site lead identification.
Social signals and content engagement.
Hiring, funding, leadership, and competitor signals.
Real-time job change tracking on the buying committee.
If you're only tracking one of these, you're missing the other four buying windows.
- Source it with the right tool for each layer.
Off-site buyer intent: Vector.
On-site lead identification: RB2B.
Social signals and content engagement: Trigify.
Hiring, funding, leadership, and competitor signals: BirdDog.
TAM mapping and account scoring: Clay.
Each tool does one job well.
The magic isn't the tools. It's what happens when they all push into the same place.
- Clay in the middle.
Every one of those platforms integrates with Clay via webhook.
The moment a signal fires anywhere in the stack, Clay knows.
Inside Clay we run the qualification layer:
Firmographic scoring on every account.
Filters to verify qualification against ICP.
Job change tracking cross-checked against the CRM weekly, so reps don't dial people who left six months ago.
Speed-to-lead routing in under 60 seconds from form fill to rep Slack alert.
Best-lead-to-best-rep tiering, so your senior rep gets the £200k lead, not round-robin.
- Prospeo for the contact data.
Verified business emails.
Catch-all detection so you don't torch your sending domain.
Mobile numbers for senior buyers.
Email verification before anything hits a domain.
Deliverability starts with clean data. Prospeo is where clean data comes from.
- Push qualified leads into the right channel.
Top-score accounts get phone-led outreach. Trellus for parallel dialling and auto-CRM logging.
Mid-tier goes into email campaigns through Instantly.
LinkedIn engagement and auto-connect handled through HeyReach.
The channel matches the tier of the lead. Not everything gets a phone call. Not everything gets an email blast.
- From here you're booking meetings.
If you're not, one of the layers above is broken. Diagnose upstream, not the copy.
If you are, move into the sales process:
Calendly to schedule meetings, with its pre-call flow builder handling confirmations and reminders by email and SMS.
Attio, HubSpot, or Salesforce as the system of record. Clay pushes updates at every stage.
BirdDog keeps surfacing fresh buying signals on every open opportunity throughout the cycle. Reps know exactly when to follow up.
- Close the loop after a deal closes.
Build a lookalike audience in Clay around that account.
Push the lookalikes back into the BirdDog signal layer.
Run a targeted campaign the moment they trigger.
Your best customers just told you exactly what your next 100 customers look like. Use it.
I share this because most teams have three or four of these tools already.
They just haven't wired them together.
Every layer sits in its own dashboard, none of them talk, and the reps end up doing manually what the stack should be doing in the background.
Wire them into Clay. Push qualified leads into the right channel. Let the system feed the reps and let the reps do the closing.
