How We Built an AI-Powered CRM and Growth Engine for a SaaS Startup

We designed and deployed a complete AI-powered CRM system for an Australian SaaS startup. 16+ live automations, 5-path lead routing, 6 platforms integrated, zero leads lost. Here is exactly how we did it.

Most growing companies have the same sales problem. Leads come in from everywhere. Follow-ups are manual. Things fall through the cracks. The pipeline lives in someone's head, not in a system.

We recently worked with an Australian SaaS startup that was about to launch publicly and had exactly this problem. Their lead handling was scattered across multiple tools, every follow-up depended on someone remembering to do it, and they had no way to scale without hiring more people.

So we built them a complete AI-powered CRM and growth system from scratch. Here is what we did and why it worked.

The Starting Point

When we came in, the situation looked familiar. Leads were arriving from website forms, outbound prospecting, and manual entries, but there was no consistent structure. A lead from the website got treated the same as a cold outreach reply. Nobody had a clear picture of where any given lead was in the process or who was responsible for it.

The sales team was spending more time on admin than on actual selling. And the founder knew that if they launched without fixing this, every new lead would just add more chaos.

They didn't need a CRM consultant. They needed someone who could design and build the entire system.

What We Built

We connected six platforms into a single, unified pipeline:

PlatformWhat It Does
WixWebsite and lead capture forms
ZapierData routing and workflow orchestration
HubSpotCore CRM, automation engine, and reporting
ApolloOutbound lead generation and data enrichment
SlackReal-time team notifications
GmailEmail sending infrastructure
Claude/OpenAIAI email drafting, lead summaries, decision support

Lead Capture That Never Misses

We consolidated every website form into a single pipeline via Zapier. Every submission gets captured, cleaned up, and routed into HubSpot with the correct source label.

We also built a fallback. If someone adds a new form to the website and forgets to map it, the system catches it anyway. This sounds like a small thing, but in our experience it is one of the most common ways companies lose leads. A new landing page goes up, the form isn't connected, and nobody notices for weeks.

After our system went live: zero leads lost.

Intelligent Lead Routing

This is where most CRM setups fall short. They treat every lead the same. We built a 5-path routing system:

  • High-fit leads go straight to sales with an AI-drafted personalised email ready to review and send
  • Medium-fit leads enter a nurture sequence with scheduled follow-ups
  • Cold leads get an automated drip campaign with re-qualification triggers
  • Suppressed contacts get properly tagged and excluded
  • High-intent signals (like specific website actions) get fast-tracked to senior leadership

The sales team stopped sorting through everything manually. They just worked the leads the system surfaced.

AI That Actually Helps

We built AI directly into HubSpot's workflow engine. When a lead gets routed, the system passes their context to an AI agent: their name, company, job title, how they found the website, what they clicked on.

The agent generates a personalised email draft. Not a template with their name pasted in. An actually tailored message based on who they are and why they reached out. The draft appears in the contact record for the sales rep to review and send with one click.

We deployed 16 of these automations across the full lead lifecycle:

  • First-touch personalised outreach
  • Follow-ups for engaged leads
  • Handoff emails for qualified leads
  • Deal negotiation summaries
  • Internal closure reports
  • A 6-step cold sequence running from Day 0 to Day 21

Every email has guardrails. No hallucination. No overpromising. Consistent with the brand voice. The AI drafts, but a human always approves.

The result? The sales team handles 3-4 times more leads without losing the personal feel.

Lead Intelligence

For every new lead, the system generates an internal brief automatically. Who are they, what company, why did they reach out, how relevant are they. The team can glance at a lead card and know in seconds whether it is worth a call.

These briefs update as new information comes in, so the picture sharpens over time.

One Pipeline, Two Sources

We connected Apollo (their outbound prospecting tool) into the same HubSpot lifecycle as inbound leads. Same stages, same automations, same reporting. One pipeline that shows the complete picture regardless of where the lead came from.

Real-Time Visibility

Slack notifications fire for new leads, pipeline changes, and key events. The team sees what is happening without checking HubSpot every hour.

Documentation That Actually Gets Used

We wrote a full operational handbook. Not a PDF that sits in a folder, but a practical guide covering the system architecture, role-specific instructions for sales, marketing, ops, and engineering, troubleshooting steps, and maintenance procedures.

The system runs without us. That was always the goal.

What the Client Said

"We want you to see Daap Company as your own, something you are truly a part of. Our vision has always been having a collaborative environment where everyone feels ownership, belonging, and purpose in what we deliver."

"The structure looks great. Please proceed with wiring the automations and onboarding the team."

Why This Matters Beyond One Company

We have seen this same problem in agencies, consulting firms, service businesses, and startups. The tools are different but the pattern is the same: leads come in, follow-ups are inconsistent, the pipeline is unclear, and scaling means hiring more people to do the same manual work.

It does not have to be that way. A well-designed system with AI at the decision points can handle the repetitive judgment calls (which email to send, when to follow up, how to prioritise) while your team focuses on the conversations that actually close deals.

If your sales process still depends on someone remembering to send an email or update a spreadsheet, there is a better way.
