Sales Navigator + Clay + Phantombuster: The Complete B2B Prospecting Stack

How to build a B2B prospecting machine combining Sales Navigator to find leads, Phantombuster to extract data, Clay to enrich and personalize, and a sequencer to reach out. Step by step with real costs.

Prospecting in B2B without tools is like looking for a needle in a haystack. You can do it, but it will take weeks what the right stack solves in hours. The problem isn't the lack of tools — it's that there are too many, and few people know how to connect them.

In this guide, we walk through the complete workflow we use at MAMBO to generate lists of qualified leads, enrich them with real data, and launch personalized sequences. All with tools that already exist and that you can set up yourself.

Step 1: Finding leads in Sales Navigator

LinkedIn Sales Navigator is the starting point. With over 40 search filters, it lets you define your ICP (ideal customer profile) with precision: job title, tenure in role, company size, industry, geography, headcount growth, and more.

Filters that make the difference: "Changed jobs in the last 90 days" and "Posted on LinkedIn in the last 30 days" are two filters that few people use and that change everything. A decision-maker who just took a new role is looking for vendors. One who actively posts responds to messages. Prioritize these leads over the rest.

Sales Navigator has full boolean search: AND, OR, NOT, parentheses for grouping, and quotes for exact phrases. In 2026, it added AI-powered operators that filter by dynamic signals like funding rounds or hiring spikes.

October 2026 update: in September Sales Navigator added a filter for who viewed your Company Page in the past 90 days, search by describing the buyer, a weekly alert digest and warm introduction badges.
What's new in Sales Navigator 2026

• USD 120/mo, Core: For individual operators. 50 InMail credits/month. Advanced lead and account filters.
• USD 160/mo, Advanced: Adds TeamLink (intros via colleagues), intent signals, team management, and CRM-embedded experiences.
• USD 1,600+/yr, Advanced Plus: Custom pricing. Bidirectional CRM sync (Salesforce, HubSpot, Dynamics).

Step 2: Extracting data with Phantombuster

Sales Navigator lets you search but not export. That's where Phantombuster comes in: an automation platform with "Phantoms" (pre-built scripts) that extract data from LinkedIn without writing any code.

The Phantoms we use most

• Sales Navigator Search Export: give it the URL of your search and it exports all profiles to CSV with name, title, company, and LinkedIn URL. The most-used Phantom on the platform.
• LinkedIn Profile Scraper: takes a list of URLs and extracts work history, education, skills, mutual connections, and recent posts.
• LinkedIn Connection Sender: sends personalized connection requests at scale.
• LinkedIn Message Sender: sends follow-ups to first-degree connections.

Watch LinkedIn's limits: Phantombuster connects via LinkedIn session cookie, which violates the terms of service. In 2026, detection has improved: data center IPs get flagged faster than residential proxies. Use it with moderation, space out actions, and don't exceed LinkedIn's daily limits (80-100 connections/day, 150 profile visits).

Phantombuster pricing starts at USD 56/month (annual plan) or USD 69/month (monthly). For an individual operator, the basic plan is usually enough.

Step 3: Enriching and personalizing with Clay

Clay is where the magic happens. It's a programmable enrichment platform that connects over 150 data providers in a single flow. The star feature is Waterfall Enrichment: instead of looking up a lead's email from a single provider (which has 40-60% coverage), Clay chains 3 to 5 providers in cascade. If the first doesn't find it, it tries the second, and so on. The result: 80-95% email find rates.

But Clay isn't just emails. It enriches with firmographics (size, industry, revenue), technographics (tech stack), intent signals (hiring, funding rounds, publications), and social data. And with Claygent, its AI agent, you can generate personalized opening lines for each contact by reading their LinkedIn profile.

• USD 0, Free: 100 data credits, 500 actions/month. For testing.
• USD 185/mo, Launch: 2,500 credits, 15,000 actions/month. The plan we use most.
• USD 495/mo, Growth: CRM sync, webhooks, HTTP API, web intent tracking.

Step 4: Launching outreach sequences

With enriched leads and personalized lines, the last step is moving them to a sequencing tool. The main options:

• Instantly (from USD 37/mo): ideal for high-volume cold email. Unlimited mailbox rotation, AI warm-up, and deliverability optimization. No built-in database — you bring your leads.
• Lemlist (from USD 69/mo): best creative personalization (video, custom images, dynamic landing pages). More advanced LinkedIn automation than Apollo.
• La Growth Machine (from EUR 60/mo): five channels in one coordinated sequence: LinkedIn, email, voice messages, Twitter/X, and phone. GDPR compliant by default.
• Apollo.io (from USD 49/mo): all-in-one with a database of 275M+ contacts. Combines data + sequences + calls. Ideal if you want a single tool.

Total stack cost

For an individual operator, the complete stack costs between USD 400 and USD 450/month: Sales Navigator Core (USD 120) + Phantombuster (USD 56-69) + Clay Launch (USD 185) + sequencing tool (USD 37-69). Sounds like a lot until you calculate what it replaces: 20+ hours per week of manual SDR work.

Conclusion

The 2026 B2B prospecting stack isn't about one magic tool — it's about four tools that connect well: one to find (Sales Navigator), one to extract (Phantombuster), one to enrich and personalize (Clay), and one to reach out (Instantly, Lemlist, or LGM). Build the flow once, iterate on filters and messaging with data, and scale without adding hours of manual work.

At MAMBO, we run this stack every day for our clients — from ICP definition to the booked meeting. If you want us to set it up for you without spending months on the learning curve, let's talk.
