The AI SDR that lives in your Slack.

Three things, end-to-end. (1) Outbound: dials prospects on your list via Telnyx using our cloned natural voice, runs a discovery script you approved, books the meeting on your calendar. (2) Speed-to-lead: when a form fills on your site, Mavrick calls the lead in under 30 seconds — see /for/speed-to-lead for the full 14-year-old-problem context. (3) Handoff: posts a structured Slack card to your sales channel with the call summary, qualification notes, and next-step recommendation. Your human rep picks up where Mavrick stopped — no context loss.

Median 8–12 seconds from form submit to Mavrick dialing, with the carrier ringing the lead's phone inside 30 seconds end-to-end. The cap is a deliberate 30s in case of cold-start latency on the voice-agent runtime. By comparison, the industry-average B2B lead response time is ~42 hours (RevenueHero, 2024). Only 7% of B2B companies meet the 5-minute benchmark. Mavrick is structurally always-under-30s — humans can't compete on this axis.

Outbound carrier: Telnyx (~$1.50/mo per DID, $0.005/min outbound US — about 70% cheaper than Twilio at scale). Voice rooms + agent runtime: LiveKit. The model layer — real-time STT, a frontier reasoning model, and natural-voice TTS — is a fine-tuned stack we keep proprietary. DID pool is shared across workspaces with area-code matching for local-presence dialing.

Not the goal. Mavrick is the always-on first responder — it picks up the call no human can pick up at 11pm or during your team's all-hands. When Mavrick qualifies a lead, it hands off cleanly to a human rep with full context. Most teams using Mavrick keep their senior AEs and let Mavrick eat the qualification grind that burns out junior SDRs.

Mavrick's voice agent identifies as AI when asked. If the lead pushes back, Mavrick offers to schedule a human call, sends an SMS with a calendar link, and posts the disposition to your Slack so your rep can follow up personally. The 'always pretend to be human' anti-pattern is explicitly banned by Mavrick's Constitution (see /constitution).

Cleared-hot is a one-time script approval, not a per-call approval. You approve the discovery script and qualification criteria once. From then on, Mavrick executes consistently against the approved playbook. The approval gate kicks in only when Mavrick wants to mutate something downstream — book a meeting, send an email, update a CRM record. That's a one-click confirmation in Slack.

HubSpot, Salesforce, Pipedrive, Close, Attio, and any CRM exposed through the managed connector layer (3,200+ tools). Mavrick writes the call summary + disposition + next-step into the CRM record automatically. The same Slack handoff card includes a deep link to the CRM record for one-click human takeover.

Apten is SMS-only and $49/mo. Verse.ai is voice + SMS but desktop-routed and $5K/mo. Drift is chat-only and ~$2.5K/mo. Mavrick is voice + SMS + email + Slack-native handoff, starts at free (10 missions), $50/mo Pilot. The unique combination: voice + Slack-native routing + cleared-hot approval architecture. See /for/speed-to-lead for the full comparison matrix.

Our voice quality is genuinely hard to distinguish from a human in a brief sales call. The default voice is a neutral US-male tone that's been A/B tested against 4 alternatives and won on lead-completion rate. Custom voice clones (your own founder's voice, for example) are available on Pilot and above.

Recruit (free): 10 missions to evaluate — covers ~5-8 outbound dials or ~15-20 lead qualifications. Pilot ($50/mo): 20,000 credits ≈ 60-100 missions/mo. Enterprise: custom pricing for high-volume dial pools + dedicated DID provisioning + 99.9% SLA. See /pricing for the full breakdown. No per-seat fees on any tier.
