DialForge — White-Label AI Voice Calling Agent for Sales Agencies Who Never Want to Cold Call Again
Cold calling is everyone's least favorite task and the one thing that still converts. DialForge packages an AI voice calling agent as a white-label platform that agencies resell to SMB clients — it calls leads, qualifies them, logs to CRM, and books meetings, all without a human touching a phone. Your agency becomes the hero, the AI does the dialing.

Validated by Real Pain
— sourced from real community discussions
A developer built an automated lead-calling system and stated they would never do manual cold outreach again, signaling strong personal ROI that maps directly to a commercial agency use case.
What is it?
Sales agencies running outreach for SMB clients spend 40% of their time on cold calling grunt work. DialForge is a white-label platform where agencies configure AI voice agents (via Twilio + ElevenLabs) for each client, upload lead lists, set qualifying scripts, and the agent calls, transcribes, scores intent, logs to HubSpot or Pipedrive, and books calendar slots via Cal.com. Agencies brand it as their own proprietary calling tech and charge clients $500-$2,000/month. Validated pain: a developer built a similar system on n8n and said they would never do manual cold outreach again, which is a product signal not just a personal preference.
Why now?
ElevenLabs Turbo v2.5 dropped latency to under 300ms in late 2025, making real-time AI voice conversations indistinguishable from human calls for the first time at a viable cost for agencies.
- ▸AI voice agent calls lead lists using Twilio, ElevenLabs voice, and Deepgram transcription with configurable qualifying scripts.
- ▸Real-time intent scoring via Claude API classifies each call as hot, warm, or not interested with transcript stored.
- ▸Auto-log to HubSpot or Pipedrive with call recording, transcript, and intent score attached to contact record.
- ▸Cal.com calendar booking triggered when lead expresses interest, confirmation SMS sent via Twilio.
Target Audience
B2B sales agencies and lead gen consultancies managing outreach for 5-20 SMB clients, ~15,000 agencies in the US.
Example Use Case
A lead gen agency managing 8 SMB clients deploys DialForge branded as their own, calls 300 leads per week per client, qualifies 40 per client as hot prospects, logs all calls to HubSpot, and books 12 meetings per client — all without an SDR touching a phone.
User Stories
- ▸As a sales agency owner, I want to deploy AI calling agents for each client, so that I eliminate SDR labor costs while delivering more qualified meetings.
- ▸As an agency, I want white-label branding on the platform, so that I can resell it as my proprietary technology at a premium.
- ▸As a campaign manager, I want every call transcript and intent score automatically logged to HubSpot, so that my clients see ROI without any manual reporting.
Done When
- ✓Calling: done when a lead in the campaign queue receives an AI outbound call with the configured script and the call is logged with recording URL.
- ✓Transcription: done when the full call transcript appears in the dashboard within 60 seconds of call end.
- ✓CRM sync: done when a hot-scored lead call creates or updates a HubSpot contact with transcript note and intent score visible in HubSpot.
- ✓Booking: done when a hot lead says yes to a meeting and receives a Cal.com confirmation link via SMS within 2 minutes of call end.

What's the competition?
Competition Level
Medium
Similar Products
AirCall is human-agent focused with no AI calling. Bland.ai does AI calling but no white-label reseller model. Synthflow AI has white-label but limited CRM integration depth — DialForge wins on agency-first white-label plus deep CRM logging.
Competitive Advantage
White-label angle means agencies become resellers not just users, creating strong lock-in. Competitors like AirCall and Kixie are human-agent tools — no AI-native white-label calling platform exists at this price point.
Regulatory Risks
TCPA compliance required for US automated calling — only call leads who have given prior express written consent. Add mandatory opt-out handling to every call script. FCC rules apply.
What's the roadmap?
Feature Roadmap
V1 (launch): AI outbound calling, transcript + intent scoring, HubSpot sync, Cal.com booking. V2 (month 2-3): white-label custom domain, Pipedrive integration, call A/B script testing. V3 (month 4+): inbound call handling, multi-language, agency analytics dashboard.
Milestone Plan
Phase 1 (Week 1-2): Twilio call + ElevenLabs TTS + Deepgram STT pipeline working end-to-end. Phase 2 (Week 3-4): Claude scoring, HubSpot sync, Cal.com booking, Stripe billing live. Phase 3 (Month 2): 3 paying agencies, white-label subdomain shipped.
How do you build it?

Next.js, Twilio Voice API, ElevenLabs TTS, Deepgram STT, Claude API for intent scoring, HubSpot API, Cal.com API, Supabase, Stripe — build with Cursor for telephony logic, v0 for agency dashboard.
Suggested Frameworks
Twilio Voice SDK, ElevenLabs Streaming API, Deepgram real-time transcription
Time to Ship
4 weeks
Required Skills
Twilio Voice webhooks, ElevenLabs streaming TTS, Deepgram real-time STT, Claude intent scoring, CRM OAuth integrations.
Resources
Twilio Voice docs, ElevenLabs API docs, Deepgram streaming docs, HubSpot CRM API, Cal.com API docs.
MVP Scope
app/page.tsx (landing), app/dashboard/page.tsx (agency campaign manager), app/api/call/route.ts (Twilio call initiation), app/api/webhook/twilio/route.ts (Twilio status callbacks), app/api/score/route.ts (Claude intent scoring), lib/elevenlabs.ts (TTS streaming helper), lib/deepgram.ts (STT transcription), lib/hubspot.ts (CRM sync), lib/calcom.ts (booking trigger), lib/db/schema.ts (agencies, campaigns, leads, call_logs), components/CampaignBuilder.tsx (script config UI), .env.example.
Core User Journey
Agency signs up -> configures client script and lead list -> launches campaign -> AI calls all leads -> reviews scored transcripts -> synced data appears in client HubSpot.
Architecture Pattern
Lead list upload -> Supabase queue -> Twilio outbound call -> ElevenLabs TTS streams script -> Deepgram STT transcribes response -> Claude scores intent -> HubSpot API logs call -> Cal.com books meeting if hot lead.
Data Model
Agency has many Clients. Client has many Campaigns. Campaign has many Leads. Lead has many CallLogs. CallLog has one IntentScore and one Transcript.
Integration Points
Twilio Voice API for calling, ElevenLabs for voice synthesis, Deepgram for transcription, Claude API for intent scoring, HubSpot API for CRM logging, Cal.com API for booking, Stripe for billing.
V1 Scope Boundaries
V1 excludes: inbound call handling, multi-language scripts, SMS follow-up sequences, team roles within agency, custom voice cloning.
Success Definition
A paying agency configures a client campaign without founder help, runs 100 AI calls, logs results to HubSpot, books 5 meetings, and pays month two without prompting.
Challenges
TCPA compliance for automated calling in the US is strict — must include opt-out handling and only call consent-given leads. This is the #1 legal risk. Distribution challenge: agency owners are skeptical of AI calling quality — demos must be indistinguishable from human calls to convert.
Avoid These Pitfalls
Do not launch without TCPA opt-out handling baked into every call script — this is a legal landmine. Do not use low-quality TTS voices — ElevenLabs Turbo v2 is the minimum acceptable quality for agency demos. Finding first agency takes 3x longer than expected — budget 6 weeks for first paying customer.
Security Requirements
Supabase Auth with Google OAuth, RLS on agency and client tables, call recordings encrypted in Supabase Storage, rate limit 10 concurrent calls per agency, TCPA opt-out flag stored per lead.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and storage, GitHub Actions for CI, Sentry for errors, Twilio media streams via WebSocket handled in Vercel Edge Functions.
Performance Targets
20 concurrent calls per agency at launch, Deepgram transcription latency under 500ms, dashboard call log loads under 2s, ElevenLabs TTS under 300ms first chunk.

First Run Experience
On first run: dashboard shows a pre-configured demo campaign with 10 mock leads and 5 completed call logs with transcripts and intent scores already visible. User can immediately play a sample call recording and read the transcript. No manual config required: demo data seeded with realistic call outcomes, Twilio sandbox mode active.
How to build it, step by step
1. Define schema: agencies, clients, campaigns, leads (status, intent_score), call_logs (transcript, recording_url, duration) in Supabase. 2. Run npx create-next-app dialforge and install twilio, @deepgram/sdk, supabase-js, stripe. 3. Build Twilio outbound call initiator in /api/call that reads lead from queue and dials via Twilio REST API. 4. Build Twilio webhook handler in /api/webhook/twilio that receives call status events and streams ElevenLabs TTS as TwiML response. 5. Integrate Deepgram real-time STT on the Twilio MediaStream WebSocket to transcribe prospect speech. 6. Write Claude intent scoring prompt in /api/score that classifies transcript as hot/warm/not-interested with reasoning. 7. Build HubSpot OAuth integration in lib/hubspot.ts that creates contact and logs call note with transcript and score. 8. Implement Cal.com booking trigger in lib/calcom.ts that fires when intent_score equals hot and sends confirmation SMS via Twilio. 9. Build CampaignBuilder component in v0 where agency configures script, uploads CSV lead list, and views call results dashboard. 10. Verify: run a test campaign against Twilio test credentials, confirm call transcript appears in dashboard, intent score logged, and HubSpot sandbox contact updated.
