Call Eva
AI voice calling agent for business conversations
Sales teams waste 60% of their time on calls that go nowhere - unqualified leads, wrong numbers, voicemails. Call Eva handles the first conversation, qualifies the lead against your criteria, captures structured data, and only routes qualified prospects to your team.

The problem
Inside sales teams spend 60-70% of their time on non-selling activities - dialing, leaving voicemails, qualifying tire-kickers, updating CRM records. By the time a rep reaches a qualified prospect, they've already burned through their peak energy on dead-end calls.
Cost of inaction
An inside sales rep costs $60K-$80K/year fully loaded. If 60% of their time is spent on non-selling activity, that's $36K-$48K per rep per year in wasted capacity. A 10-person team wastes $360K-$480K annually on calls that an AI could handle.
Our approach
We analyzed 5,000+ recorded sales calls to identify the qualification patterns that separate good leads from bad. The top 20% of reps all follow similar opening sequences - they just execute them faster and more consistently.
Call Eva replicates the best rep's opening sequence on every call. It introduces, asks qualification questions in natural conversation, handles common objections, and makes a routing decision - all in under 3 minutes.
The structured data capture was critical. After every call, Call Eva updates the CRM with qualification answers, sentiment score, and a recommended next action. The rep starts their follow-up call with full context.
Key insight
The first 2-3 minutes of a sales call are formulaic - introduction, qualification questions, need assessment. This is precisely what AI handles well: structured conversation with branching logic. Save the human rep for the consultative conversation that closes deals.

Response time
Call Eva's qualification matches human rep decisions 94% of the time - and is more consistent because it never skips questions.
Sales reps spend 3x more time on qualified conversations because Call Eva handles initial outreach, qualification, and CRM updates.
Inbound leads get a callback within 60 seconds - 24/7, including weekends. Speed-to-lead is the strongest predictor of conversion.

Key decisions
Dual-mode: inbound + outbound
Inbound speed-to-lead and outbound qualification are different workflows but share the same voice pipeline. Building both on one platform maximized reuse.
Configurable conversation trees
Every business has different qualification criteria. A no-code conversation builder lets sales managers define questions, branching logic, and routing rules without engineering.
Real-time CRM sync
Call data must appear in Salesforce/HubSpot immediately - not in a batch. Reps need context before their follow-up call, not after.
Streaming voice pipeline
Natural conversation requires <500ms latency. We stream speech-to-text and text-to-speech in parallel, with LLM reasoning running on partial transcripts for faster responses.

What we learned
Speed-to-lead matters more than anything
Leads contacted within 60 seconds convert at 5x the rate of leads contacted after 30 minutes. An always-on AI agent eliminates the response-time problem entirely.
Sales reps love it when it works
Initial skepticism from sales teams disappeared when they realized Call Eva wasn't replacing them - it was removing the worst part of their job and giving them warmer conversations.
Conversation design is harder than tech
The voice pipeline was a solved problem. Making the AI sound natural, handle interruptions, and handle objections gracefully required weeks of conversation design iteration.
Growth strategy
Targeted sales teams at B2B SaaS companies with 5-20 reps - large enough to feel qualification pain, small enough to decide quickly. The ROI math ($48K saved per rep per year) makes the business case self-evident.
Frequently asked questions
Call Eva is trained on common objections for your product/service. It responds naturally with pre-approved messaging, and escalates to a human rep when conversations move beyond qualification.
