What Michael Does

Michael is an AI-powered BDR agent that handles the hardest parts of outbound sales development. His core capability is cold calling: you configure your pitch, provide lead details, and Michael makes the call with realistic voice synthesis, natural conversation flow, and real-time objection handling. But he goes beyond just dialing. Michael drafts outbound messages, generates call summaries and debriefs, and produces ready-to-send follow-up emails from the context of each interaction.

He doesn't read a script robotically. Michael adapts. He listens to prospect responses, pivots based on objections, identifies buying signals, and steers conversations toward booking a meeting. After the call, he synthesizes everything into a structured debrief with performance metrics, a full transcript, and actionable next steps. The entire workflow happens autonomously while you monitor the live transcript.

How It Works

1

Configure Your Outreach

Tell Michael who you're targeting and what you're selling. Enter your lead's information (name, company, role), define your messaging and value proposition, and select the tone you want Michael to use. You can preview his voice before the call starts to make sure it matches your brand. The setup takes under a minute.

Michael adapts to your pitch. The more context you provide about your product, the prospect's pain points, and your value proposition, the more natural and effective the conversation becomes. He uses this context to handle objections, draft relevant outbound messages, and steer calls toward booking a meeting.

2

Michael Makes the Call

Click "Start Call" and Michael dials your prospect. You can monitor the entire conversation in real-time through a live transcript that updates as each person speaks. Michael handles the introduction, delivers your pitch, responds to questions and objections, and works toward booking a meeting. The call status, duration, and speaker turns are all visible in the interface while the call is live.

3

Get Your Summary & Debrief

When the call ends, Michael hands you a complete call summary and debrief. This includes the full conversation transcript with speaker attribution, performance metrics (call duration, outcome, meeting booked status), and an AI-drafted follow-up message you can copy and send immediately. The debrief is structured so you can paste relevant sections into your CRM, share with your team, or use for coaching.

Full Capability Breakdown

Realistic Voice Synthesis

Michael's voice isn't a flat text-to-speech output. He uses advanced voice synthesis that captures natural speech patterns, including pacing, emphasis, and conversational pauses. Prospects hear what sounds like a real BDR on the other end of the line. You can preview and adjust the voice before making any calls, ensuring it aligns with your brand tone.

Real-Time Objection Handling

Cold calls don't follow scripts perfectly. Prospects interrupt, ask unexpected questions, and raise objections. Michael is built to handle this. He listens to what the prospect actually says and responds contextually. If they say "I'm not interested," Michael doesn't repeat the pitch. He acknowledges the concern and pivots. If they ask about pricing, he addresses it with the context you provided. If they mention a competitor, he differentiates.

Message Drafting & Follow-ups

A BDR's job doesn't end when the call does. Michael drafts outbound messages and follow-up emails using the full context of the conversation. The messaging reflects what was discussed, the objections raised, and the next steps agreed upon. You get a ready-to-send email the moment the call ends, not a template you have to customize yourself.

Call Summaries & Debriefs

Every call produces a structured summary with the key takeaways, prospect sentiment, meeting outcome, and performance metrics. The debrief goes deeper: full transcript with speaker attribution, objection analysis, and recommended next steps. Paste the summary into your CRM, share the debrief with your manager, or use it for self-coaching.

Meeting Booking

The goal of most cold calls is to book a meeting, not to close a deal on the spot. Michael is optimized for exactly this. When the conversation is going well, he proactively suggests scheduling a meeting and handles the logistics. The outcome is captured in your debrief so you know exactly what was committed to and when.

Live Call Monitoring

You're never blind during a Michael call. The interface shows a real-time transcript with clear speaker identification (Michael vs. the prospect), call status indicators (ringing, connected, speaking), and call duration. You can end the call manually at any point if needed. This transparency means you always know exactly what's being said on your behalf.

The entire BDR workflow in three steps: Setup, Call, Debrief. Configure your pitch in under a minute, let Michael handle the conversation, and get a complete summary with transcript, drafted follow-up messages, and performance metrics when the call ends.

The Technical Architecture

Michael's BDR capabilities are powered by a multi-layer architecture that separates voice synthesis, conversation intelligence, message drafting, and post-call analysis into specialized components.

LayerTechnologyRole
Voice SynthesisAI Voice EngineNatural, human-sounding voice for outbound calls with adjustable tone
Conversation AILLM-Powered AgentReal-time dialogue management, objection handling, and meeting booking

This architecture is deliberate. The voice synthesis layer handles natural-sounding speech. The conversation AI manages real-time dialogue flow. And Claude handles message drafting, call summaries, and debriefs because it excels at structured analysis and professional communication. Each layer does what it does best.

Michael vs. The Traditional BDR Stack

Outbound sales teams spend thousands per month on dialers, SDR salaries, sequencing tools, and calling infrastructure. Michael handles the initial outreach autonomously at zero cost.

Traditional BDR Stack

$3,000+/month
  • Power dialer software ($150-$300/user/mo)
  • SDR salary and commission ($4,000-$6,000/mo base)
  • Call coaching and QA tools ($50-$100/user/mo)
  • Weeks of ramp time for new hires
  • Inconsistent call quality and high turnover
  • Manual note-taking and CRM data entry

Michael by Mantyl

$0/forever
  • AI BDR agent with natural cold calling ability
  • Real-time objection handling and meeting booking
  • AI-drafted outbound messages and follow-up emails
  • Structured call summaries and debriefs
  • Live transcript with speaker attribution
  • Zero ramp time, zero setup, zero cost

Michael replaces the initial BDR workflow entirely. He won't replace your entire sales team, but for founders doing their own outbound, small teams without dedicated BDRs, and anyone who needs to make more initial contacts without hiring more people, Michael handles the hardest parts of the process: the cold call, the summary, and the follow-up.

How Michael Differs from Traditional BDR Tools

Michael isn't a power dialer or a sequencing tool. Those products still require a human on every call and manual follow-up writing. Michael is an autonomous BDR agent that handles the entire outreach workflow: the cold call, the summary, the debrief, and the follow-up message.

Autonomous BDR Workflow, Not Assisted Dialing

Tools like Salesloft, Outreach, and Orum help humans dial faster and sequence emails. They still need a rep on the line for every call and someone to write every follow-up. Michael is the rep on the line and the writer at the desk. He makes the call, handles objections, books meetings, summarizes the conversation, and drafts the follow-up. You monitor via live transcript and step in only if you choose to.

Consistent Quality on Every Call

Human SDRs have bad days, get fatigued after 50 dials, and deviate from scripts. Michael delivers the same quality pitch every time while adapting naturally to each prospect's responses. No call fatigue, no script drift, no off-days.

Instant Summaries, Not Manual CRM Entry

After a traditional cold call, reps spend 5 minutes logging notes in the CRM and another 5 drafting a follow-up. Michael gives you a structured summary, full debrief, and a ready-to-send follow-up message the moment the call ends. Copy what you need, paste it where it belongs, and move on to the next opportunity.

Free, No Strings

Michael isn't a trial. He isn't gated behind a demo request or a sales call. He's fully free with full functionality. Mantyl built him as a demonstration of what AI voice agents can do for outbound sales teams, and as a proof point for the custom automation work they build for clients.

Who Should Use Michael

1

Founders Running Outbound Themselves

You're building your product and closing deals at the same time. You know you need to make cold calls but you don't have hours to spend on the phone. Michael handles the initial outreach so you can focus on the conversations that matter: the ones where the prospect is already interested.

2

Small Teams Without Dedicated BDRs

Hiring a BDR costs $60,000-$80,000/year before you factor in tools, training, and ramp time. Michael gives your team full BDR capacity without the headcount. Deploy him on your prospect list and let your AEs focus on closing the meetings he books.

3

Sales Leaders Testing New Markets

You want to test a new vertical, geography, or messaging angle but don't want to retrain your team or hire new reps for what might be a short experiment. Use Michael to run the initial outreach and gauge response before committing resources.

4

Sales Teams Supplementing Human Outreach

Your SDRs handle the high-priority accounts. Michael handles the long-tail prospects and cold lists that would otherwise sit untouched. He generates meetings from contacts that your team wouldn't have time to reach manually.

Put Michael to Work Right Now

No sign-up, no credit card, no setup. Configure your pitch, enter your lead, and let Michael handle the outreach. You'll get a live transcript, structured call summary, debrief, and a drafted follow-up message ready to send.
