Callum

Product Introduction

1. Definition: Callum is an AI-powered calendar automation platform (technical category: SaaS scheduling assistant) specifically engineered for Google Calendar users. It leverages natural language processing (NLP) and machine learning to automate team scheduling, meeting management, and calendar optimization.
2. Core Value Proposition: Callum eliminates manual calendar administration by enabling teams to schedule, reschedule, and prepare meetings through conversational commands. Its core value lies in resolving multi-person scheduling conflicts, integrating business context from CRMs/ATS systems, and reducing scheduling friction via NLP.

Main Features

1. Multi-Person Scheduling Engine: Automatically identifies overlapping availability across teams by syncing with Google Calendar data. Uses constraint-based algorithms to filter times based on meeting duration, time zones, and buffer periods between events. Generates shareable availability grids with conflict-free slots.
2. Natural Language Processing (NLP) Interpreter: Parses unstructured commands (e.g., "Schedule quarterly planning Thursday at noon with Jim, Marta and Alice") using transformer-based models. Extracts entities (attendees, time, duration, location) and executes calendar actions without manual input or form-filling.
3. Contextual Meeting Intelligence: Integrates with HubSpot, Greenhouse, and other CRMs/ATS via APIs. Auto-populates meeting details (deal stage, KPIs, attendee history) and generates prep materials (agendas, interview questions) by cross-referencing calendar events with connected data sources.
4. Smart Rescheduling System: Dynamically proposes conflict-free alternatives when moving meetings. Analyzes attendee calendars, prioritizes time slots based on proximity to original meeting and existing commitments, and auto-sends update notifications via Google Calendar’s API.
5. Cross-Platform Accessibility: Operates via web dashboard, iOS app, Slack integration, and upcoming ChatGPT extension. Syncs in real-time with Google Calendar using OAuth 2.0 authentication, ensuring consistent scheduling capabilities across devices.

Problems Solved

1. Pain Point: Eliminates back-and-forth emails for group scheduling (saves 20+ minutes per meeting) and reduces no-shows/late starts caused by manual errors. Addresses calendar blindness by auto-enforcing scheduling rules (e.g., buffer times, travel constraints).
2. Target Audience:
   • Sales Teams: Account executives managing 50+ monthly client meetings
   • Engineering/Product Managers: Coordinating cross-functional reviews
   • Recruiters: Scheduling high-volume interviews via Greenhouse
   • Agency Directors: Managing external/client calendars
   • Remote Teams: Navigating multi-time-zone scheduling
3. Use Cases:
   • Automatically booking 10-person sprint planning sessions across 3 time zones
   • Rescheduling customer demos when deals advance to negotiation stage
   • Adding interview question templates to newly scheduled design reviews
   • Blocking focus time after late-night meetings to prevent burnout
   • Generating sales call prep docs using HubSpot deal context

Unique Advantages

1. Differentiation: Unlike Calendly (link-based) or x.ai (email-focused), Callum operates conversationally within calendars and understands team-specific constraints. Outperforms Google’s "Find a Time" by integrating external data (CRM/ATS) and auto-generating meeting intelligence.
2. Key Innovation: Proprietary NLP models trained on scheduling semantics (e.g., "before lunch," "end of day") combined with graph-based algorithms for conflict resolution. This enables human-like interpretation of complex requests (e.g., "Move dentist appointment to next week if Sarah is free").

Frequently Asked Questions (FAQ)

1. How does Callum ensure calendar data privacy?
   Callum uses Google OAuth 2.0 for read-only calendar access, encrypts all data in transit (TLS 1.3), and processes commands without storing raw event details. It complies with GDPR/CCPA and allows granular permission controls.
2. Can Callum schedule meetings with external attendees?
   Yes, Callum automatically checks free/busy status for any Google Calendar user and sends calendar invites via Google’s API. External attendees receive standard Google Calendar invitations.
3. What integrations does Callum support beyond Google Calendar?
   Currently supports HubSpot, Greenhouse, and Slack, with Outlook Calendar and ChatGPT integrations launching soon. API documentation allows custom connections to CRMs like Salesforce.
4. How does Callum handle time zone differences for global teams?
   The system auto-detects attendee time zones, converts all time references to local formats, and excludes slots outside working hours based on each user’s Google Calendar settings.
