The Core Stack
Seven tools, one system
From list building to inbox infrastructure to the messages that get sent. This is the exact flow we run every campaign through.

Apollo
270M+ B2B contact database with filters that actually work. Our default for ICP list building, best data accuracy on Australian companies we have tested.

FullEnrich
Email and mobile enrichment through 15+ data providers in sequence. When one misses, the next catches it, significantly higher hit rates on AU contacts than any single source tool.

Prospeo
Verified email and mobile finder with a clean LinkedIn Sales Nav extractor. Our pick when we need a specific decision maker's direct mobile.

Zapmail
Provisions Google Workspace and Microsoft 365 mailboxes with SPF, DKIM and DMARC auto configured. The layer beneath every cold email campaign, non negotiable for agency scale outbound.

Instantly
Unlimited inbox accounts, automated warmup, unified inbox. Our default email platform for clients who need polished UX and the best in class deliverability tools.

Smartlead
Master inbox model for managing campaigns across many client workspaces from one screen. Our pick for heaviest multi client agency setups where Instantly's per workspace model gets in the way.

Lemlist
Email plus LinkedIn plus cold calls in one sequence builder. The pick when a client wants tightly orchestrated multichannel outreach in a single tool, and the most polished UX in the category.
How It Connects
One flow, four steps
The tools above do not sit in isolation. They feed each other in a specific order, and the order matters.
List
Apollo builds the target account list.
Enrich
FullEnrich and Prospeo find emails and mobiles.
Infrastructure
Zapmail provisions the sending mailboxes.
Send
Instantly, Smartlead, or Lemlist runs campaigns alongside our phone calls.
Beyond the Core
Three tools we use outside the core stack
These do not sit in the linear flow above, but they make everything else work better.

Relevance AI
AI agent platform we use to automate prospect research and personalisation at scale. Australian founded (Sydney). Build an agent once, run it across thousands of contacts.

Taplio
The LinkedIn content tool that powers the Nousu LinkedIn presence. Schedule posts, analyse what resonates, surface what is working for other creators in the niche right now.

Amplemarket
The all in one sales platform, data, sequencing and AI features in a single product. The alternative for teams who would rather buy one platform than stitch a stack together.
