Maven — Voice-Based AI Sales Productivity

Bespoke LLMs trained on sales domain language that convert post-call voice notes into live Salesforce entries — contacts, opportunities, custom objects — with multi-language support and gamified adoption.

The problem

Sales reps spend 28% of their working time on CRM administration — logging calls, updating contacts, recording outcomes, moving opportunities through stages. That's more than a day a week per rep lost to data entry.

Generic transcription tools exist, but they fail on two counts: domain-specific language (product names, deal terms, customer-specific context) produces inaccurate transcription, and they don't integrate natively with Salesforce custom objects.

Generic transcription tools lack the domain context to accurately capture sales conversations. The result is transcripts that require more editing than just typing the update directly.

What we built

Maven: a mobile app combining bespoke domain-specific LLMs with native Salesforce API integration. Reps record a voice note after a call. The system transcribes, interprets, and populates Salesforce — contacts, opportunities, activities, custom objects — in real time.

  • Bespoke LLMs trained on sales domain language — significantly outperforming generic transcription on domain accuracy
  • Native Salesforce API — auto-populates contacts, opportunities, and custom objects without manual data entry
  • Multi-language voice recognition — built for global sales teams across geographies
  • Gamified productivity scoring — team leaderboards tracking call activity, conversion rates, and CRM hygiene
  • Mobile-first design — iOS and Android, designed for field reps and remote teams

The outcome

30%+ of sales team time reclaimed — measured against baseline. Real-time Salesforce updates from voice without any manual data entry step.

Salesforce AppExchange

A listing on the Salesforce AppExchange is planned — which would make Maven available to the full Salesforce customer base as a native app rather than a custom integration. The bespoke LLM approach creates a defensible accuracy advantage that generic transcription tools cannot match without domain-specific fine-tuning.
