FuseBase — Building an Omnichannel Sales Engine for AI Agents

← Back to all case studies

Client

FuseBase — B2C AI product focused on AI agents and productivity workflows.

Challenge

FuseBase initially approached L1 Advisory with a request to build a relatively simple sales engine around their AI agent product. After a detailed GTM and outreach audit, we identified that the core issue was not tooling or lead volume — the missing layer was a structured omnichannel outbound architecture.

The existing outreach lacked:

  • ICP segmentation
  • channel orchestration
  • response sequencing
  • behavioral follow-ups
  • visibility into engagement patterns

Diagnosis

Instead of scaling outbound volume, we focused on fixing the communication architecture first. We identified that LinkedIn could become a primary outbound acquisition channel when combined with multi-step engagement logic, predefined ICP clusters, behavioral triggers, personalized outreach sequencing, and coordinated touchpoints across channels.

What L1 Advisory built

ICP & outreach structure

We segmented target audiences into predefined ICP groups and crafted separate communication flows for each segment:

  • founder personas
  • AI-native operators
  • productivity-focused users
  • early adopters
  • tech decision-makers

LinkedIn outbound system

We implemented LinkedIn as a core layer of the outbound engine. The system included:

  • multi-step outreach sequences
  • connection-to-reply workflows
  • engagement warming
  • follow-up automation
  • reply tracking logic
  • behavioral branching

Omnichannel coordination

Instead of treating LinkedIn as an isolated channel, we connected it into a wider outbound architecture — creating synchronized communication flows across:

  • LinkedIn
  • email
  • content engagement
  • profile interaction
  • follow-up touchpoints

Result

The result was not just “more outreach.” It was a scalable outbound acquisition system designed around:

  • structured engagement
  • predictable reply flows
  • ICP-specific messaging
  • omnichannel visibility
  • repeatable pipeline generation

Key insight

Cold outreach stops being cold when the system understands context, timing, and behavioral sequencing.
