How it works

From cold list to funded deal — without lifting your phone.

1

AI calls your leads — at scale

Upload your list, set a campaign, and Mainline's voice AI agent dials each lead, asks qualifying questions, and books callbacks — in a natural human-sounding voice that you can clone to match your own.

2

They apply on their phone — in minutes

Qualified leads receive a one-tap link to a mobile-first application. They connect their bank with Plaid, snap a photo of their ID, and sign — no PDFs, no follow-up phone tag.

3

You submit, you fund, you get paid

Mainline surfaces qualified deals in your CRM, lets you submit to your lender network in one click, tracks every offer, and logs every dollar funded — so commissions never slip through the cracks.

Everything in one place

Stop stitching together five different tools.

Mainline replaces your dialer, your CRM, your application form, your doc collector, and your underwriting spreadsheet — with one platform built specifically for MCA brokers.

Cloned-voice AI agents

Clone your own voice (or your top closer's) and let the agent run conversations 24/7. Sounds human, follows your script, books callbacks.

Full conversation transcripts

Every call is recorded, transcribed, and analyzed by Claude AI for intent, objections, sentiment, and next-best-action — searchable from your dashboard.

MCA-specific CRM

Pipeline stages built for cash advance: New Lead → Contacted → Qualified → App Sent → Docs → Submitted → Offer → Funded. Not Salesforce hacked into shape.

Plaid-verified underwriting

Pull 3-6 months of business bank data automatically. Verify revenue, detect existing MCAs, flag NSFs, and score deals before you waste a submission slot.

Mobile-first applications

Tokenized one-tap links your applicants open on their phone. Camera capture for ID, Plaid for bank — done in 4 minutes. No PDFs. No emails back and forth.

Real-time dashboard

Today's calls, hot leads, callbacks due, applications in review, offers awaiting decision, funded this week — one screen, all live.

Built for compliance

Encrypted at rest. TLS in transit. Webhook signature verification. MFA on every admin account. KYC via Plaid Identity Verification.

Up and running in an hour

Sign up, connect your Twilio number, clone your voice, import your lead list, and start dialing. No 6-month implementation, no setup fees.

The voice that actually sounds human

Your AI agent. Your voice. Your script.

Most outbound bots get hung up on in five seconds. Mainline's voice agents are built on ElevenLabs' best-in-class conversational AI — clone your own voice from a 3-minute recording, write your script in plain English, and let it run.

  • Sounds indistinguishable from a human caller
  • Handles objections, takes notes, books callbacks
  • Logs every conversation as a searchable transcript
  • Auto-routes hot leads to a human rep mid-call
  • Stops calling DNC numbers and lost-cause leads automatically

Frequently asked

Questions you'd ask if we were on a call.

Do I need to be technical to set this up?+

No. If you can use Gmail, you can use Mainline. You sign up, connect a phone number, record a 3-minute voice sample (or pick a pre-built voice), upload your lead list, and you're calling within an hour. We handle the AI, the integrations, and the infrastructure.

Is the AI agent compliant with TCPA?+

You're responsible for ensuring your lead list complies with TCPA, DNC, and state-level calling regulations — same as a human dialer. Mainline gives you tools to honor opt-outs, respect DNC requests, and log consent, but you must operate within the rules applicable to your business.

How does the AI sound? Will my leads hang up?+

It sounds human. We use ElevenLabs' best-in-class conversational AI — the same tech behind Audible, Disney, and most major voice products. You can clone your own voice from a 3-minute recording, so callers literally hear you. In testing, recipients regularly continue 5+ minute conversations without realizing it's AI.

What integrations do you support?+

Out of the box: Plaid (bank verification + underwriting), Twilio (telephony), ElevenLabs (voice AI), Anthropic Claude (call analysis), Supabase (database). For lenders, we support custom submission integrations on the Growth plan.

Where is data stored? Is it secure?+

All data is encrypted at rest (AES-256) and in transit (TLS 1.2+). We use Supabase (Postgres) for the database, hosted on AWS in the US. Webhook signatures are verified. All admin accounts require multi-factor authentication. We follow standard fintech security practices and are actively pursuing SOC 2 Type II.

Who owns the data — me or you?+

You own all your data — leads, transcripts, applications, deals. You can export everything at any time. We process your data on your behalf as a service provider, not for our own purposes.

Can I clone the voice of someone other than myself?+

Only with their explicit, written consent. Voice cloning without consent of the voice owner is prohibited by our Terms of Service and is illegal in many jurisdictions. We require attestation of consent for each cloned voice.

Stop chasing leads. Let Mainline chase them for you.

Set up a 20-minute call. We'll show you the platform end-to-end and help you decide if it's a fit for your shop.
