The Stack We Actually Use
Before I talk about Clay, let me describe what we're actually running — because this article is grounded in real operational experience, not a theoretical tool comparison.
We're a marketing team of three people in OEM B2B manufacturing. Our sales cycle is long, our buyer list is finite, and we're not doing outbound blasts to thousands of cold contacts. We're doing targeted, account-based prospecting to a specific set of companies we already know or want to know.
Our stack has three layers:
This setup has worked well for two years. The Dealfront + HubSpot integration in particular changed how our sales team operates — they're now responding to live intent signals rather than cold outreach, which changes the conversation quality entirely. I wrote about that setup in detail in the Dealfront + HubSpot review.
The Gap We Still Have
⚠️ The problem with our current stack
The data lives in three separate places. When Dealfront identifies a company, someone still has to go to Lusha, look up the contact, and push that data into HubSpot. It's not a huge amount of work — but it's manual, it introduces errors, and it slows down the workflow at the exact moment speed matters most (when a prospect is actively on your site).
Dealfront tells us who is visiting. Lusha tells us who to call at that company. HubSpot is where we act. But moving data from step one to step two to step three is still a human task in our current setup.
This is where the data connection problem lives for most B2B teams. It's not that the tools don't work — it's that they don't automatically talk to each other at the contact enrichment level. You end up with intent data in one tab, contact data in another, and your CRM in a third.
Where Clay Enters the Picture
On March 4, 2026, Lusha launched as a native integration inside Clay. I want to be transparent here: I haven't personally set up Clay in our stack yet — this is a tool we're evaluating, not one I can review from months of daily use. But given the specific gap I just described, this integration is genuinely interesting.
Clay is a data orchestration platform. Its core value proposition is that it acts as a layer between your data sources and your CRM — pulling from multiple providers, enriching records, and pushing completed data into the tools your team actually uses. It's used heavily by outbound sales teams and GTM engineers.
With Lusha now native in Clay, the workflow I'm imagining looks like this:
What this removes is the manual enrichment step. Instead of a sales rep or marketer going to Lusha to look up a contact after Dealfront fires a signal, Clay automates that enrichment and the complete record arrives in HubSpot ready to act on.
Who This Stack Makes Sense For
I want to be honest about scale here because the answer isn't "everyone should add Clay."
For our team — three people, a defined focus customer list, and a manageable number of intent signals per week — the manual Dealfront-to-Lusha-to-HubSpot workflow is workable. The time we'd save with Clay automation versus what Clay costs needs to be weighed carefully for a small team.
The stack makes more sense as team size and prospecting volume grow:
- Small B2B team (1-5 people), focused account list: Dealfront + Lusha + HubSpot without Clay is probably sufficient. Manual enrichment is manageable when you're working a short list of known targets.
- Mid-size team doing active outbound: Clay starts to add real value. If you're processing 50+ company enrichments per week, automating the Lusha lookup step saves meaningful time and removes error.
- GTM or RevOps teams managing large lists: Clay is designed for this. The ability to run waterfall enrichment across multiple data providers — with Lusha as one of them — is where Clay genuinely earns its cost.
Why Lusha Is Still the Core Tool
Whether you add Clay or not, Lusha remains the contact enrichment layer that makes the whole stack work. The Dealfront signal tells you a company is interested — Lusha tells you who to actually contact at that company.
In our experience, the quality of Lusha's data for European B2B contacts (Finland and the wider EU market) has been consistently good. Direct phone numbers and verified emails for decision-makers at industrial companies — which can be harder to find than SaaS contacts — are generally accurate. The HubSpot integration is clean and the data lands in the right fields without manual mapping.
Clay's new Lusha integration doesn't change what Lusha does — it just makes accessing Lusha's data inside an automated workflow easier. If you're already using Lusha standalone, the Clay integration is an upgrade path, not a replacement.
Our Dealfront + Lusha + HubSpot stack works and I'd recommend it to any B2B team running account-based prospecting. The biggest friction point is the manual data movement between tools — and Clay's new Lusha integration is the most credible solution I've seen for that specific problem. We're evaluating it. For small teams with a focused account list, start with the three-tool stack first. Add Clay when your volume makes the automation genuinely worth the additional cost and setup.
The Honest Assessment
✅ What works well
- Dealfront intent signals are genuinely accurate for account-based lists
- Lusha contact data quality is strong for EU B2B contacts
- HubSpot automation handles follow-up without manual work
- Clay's Lusha integration is native — no workarounds needed
- The full stack creates a closed loop from anonymous visitor to identified contact
⚠️ What to watch
- Clay adds cost — only justified at higher prospecting volumes
- Manual enrichment gap still exists without Clay
- Stack complexity increases with each tool added
- Clay setup requires technical time to configure workflows properly
- Lusha credit costs can add up at scale
Where to Start
If you're building this stack from scratch, the order matters. Start with HubSpot as your foundation — everything else feeds into it. Add Dealfront second to get intent signals flowing. Then add Lusha to enrich the companies Dealfront identifies. Evaluate Clay once you've been running the three-tool stack for a few months and you understand where your manual bottlenecks actually are.
Don't add Clay speculatively before you understand your own workflow friction. The problem it solves — connecting data between tools — needs to be real and frequent in your workflow before the investment makes sense.
Start with Lusha
Lusha is the contact enrichment layer that makes the whole stack work — whether you add Clay or not. If you're using Dealfront or HubSpot and still manually looking up decision-maker contacts, Lusha is the missing piece.

Does Lusha now integrate with Clay?
Yes. Lusha launched as a native Clay integration on March 4, 2026. The integration supports contact enrichment, person signal enrichment, and company lookalike finding — all within Clay's workflow builder.
How do Dealfront, Lusha and HubSpot work together?
Dealfront identifies companies visiting your website and fires intent signals into HubSpot. Lusha enriches those companies with verified contact data — finding the right decision-maker's email and number. HubSpot manages the pipeline and automates follow-up. Together they create a closed loop from anonymous traffic to identified contact in your CRM.
What does Clay add to a Lusha and HubSpot stack?
Clay automates the enrichment workflow — removing the manual step of looking up contacts in Lusha after Dealfront fires a signal. With the new native Lusha integration, Clay can enrich a company record and push the completed contact into HubSpot automatically.
Is Clay worth adding if you already use Lusha and HubSpot?
For small B2B teams with a focused account list, the manual workflow is often sufficient. Clay becomes worth evaluating when your enrichment volume is high enough that the time saved justifies the additional cost and setup complexity.
What is the biggest gap in most B2B prospecting stacks?
Connecting data between tools. Most teams have intent data in one place, contact data in another, and their CRM in a third. Moving data manually between these systems — and keeping it consistent — is where most prospecting workflows break down.
