How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Koncert when managers coaching reps from recorded calls and a remote salesfloor matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification.

Koncert is a B2B sales engagement platform built around AI-powered dialing, call recording, and coaching for outbound teams. Its dialer suite includes options such as an AI Parallel Dialer and an AI Flow Dialer that filter voicemails and connect reps to live answers to increase connected conversations and connect rates.

Koncert also includes a multi-channel cadence sequencer spanning phone, email, video, text, and social, plus caller ID management that selects local numbers and monitors number health. For practice and training, Koncert offers AI PitchLab, an add-on where reps rehearse pitches against AI-powered buyer personas without the pressure of a live prospect, with objection-handling practice and automatic transcription and scoring of performance.
