A full outbound sales stack for teams running cold email, calling, and LinkedIn outreach. Data, sequencing, AI, and call recording in one motion. This stack assembles 6 tools that work together for a total of ~$446-550/mo for a 2-rep team. Each pick is the result of weighing dozens of options in its category against the specific constraints of the audience this stack is built for: budget, team size, technical depth, and the workflow that needs to be supported.
Below is the full tool list, with the specific tier to pick, the cost, and our score. After the cards, you'll find a per-tool explanation covering why it earns its slot in this stack and when you should consider swapping it for an alternative. If your situation differs from the audience this stack targets, the swap notes will help you adapt the recommendation to your reality.
Why Each Tool Earns Its Slot
Apollo.io for Contact Data + Sequencing
The best value in B2B sales tools. Period. A contact database of 275M+ profiles, email sequencing, dialer, and LinkedIn integration, all starting at $49/user/mo. Apollo took the ZoomInfo + Outreach bundle and made it affordable. The data quality isn't ZoomInfo-level, but for most SMBs, it's good enough. For this stack, the Professional tier at $99/user/mo is the right starting point because it covers the contact data + sequencing role without paying for features the rest of this stack already handles. 275M+ contact database included.
The fit reason: Apollo.io scores 8.5/10 in our review and is built for smbs and startups wanting prospecting data + engagement in one affordable platform. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best sales engagement guide.

The result: better coverage than any single provider. The spreadsheet-like interface handles complex enrichment workflows that would take an engineer to build elsewhere.

The platform earns its price when adoption is high (80%+ calls recorded). Below that threshold, you're paying enterprise pricing for a recording tool.

Pipedrive for CRM + Pipeline
A CRM built by salespeople, for salespeople. The visual pipeline is the best in the business. Lacks the depth of HubSpot or Salesforce, but that simplicity is the whole point. For this stack, the Advanced tier at $39/user/mo is the right starting point because it covers the crm + pipeline role without paying for features the rest of this stack already handles. Best visual pipeline in the market.
The fit reason: Pipedrive scores 8.2/10 in our review and is built for small sales teams (2-20 reps) who want a pipeline-focused crm. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best crm guide.
How to Use This Stack
Three steps to set up The Outbound Engine ($500/mo) in a single afternoon:
- Sign up in the order listed. The first tool is your foundation. Get it running first, then layer on the others. Don't try to set up everything at once or you'll end up with half-configured tools and no working stack.
- Use the exact plans called out above. Vendor pricing pages push you toward higher tiers. The plans we recommend are the ones that actually fit this stack's audience. Going one tier higher usually wastes 30-40% of the spend on features you won't touch.
- Connect the integrations day one. The value of a stack is in how the tools talk to each other. CRM data should flow into email. Project management should pull from your ticketing tool. Set the integrations up before you load real data, not after.
Total cost at list pricing is ~$446-550/mo for a 2-rep team. Most of these tools discount 15-20% on annual prepay, so the real annual cost is usually 10-15% lower than 12x the monthly number. Ask sales for an annual quote when you sign up.
When to Upgrade Beyond This Stack
This stack is built for a specific stage. You'll outgrow it. The signals that you're ready for the next level usually look like one of these:
- You're hitting feature limits weekly. If you're asking your team "can our tool do this?" more than once a week and the answer is "no," it's time to look at upgraded plans or alternative tools. Our category guides help you find the next step.
- The math no longer works. Per-seat tools get expensive fast. If you doubled in size and your stack cost more than doubled, audit which tools are charging per-seat and consider flat-rate alternatives. Some of our pricing pages calculate the team math directly.
- Workflows are breaking at the seams between tools. When data isn't flowing cleanly between two tools in your stack, the answer is usually a different tool that integrates better, not more middleware. Re-evaluate which tools play well together at your new scale.
When you're ready to scale beyond this stack, browse the related stacks on the stacks index page to find the next tier up. Most teams move through 2-3 stacks as they grow from solo founder to mid-sized company.
