How Hosiqo compares and tests toolsFinal recommendation
Shortlist Agaton when coaching sales reps in real time during calls to improve objection handling and closing matters most, and Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Try them side by side on real calls before deciding — needs vary by team.

Agaton is a Stockholm-based AI conversation intelligence and revenue intelligence platform built for sales and customer-facing teams. The product applies voice AI to analyze agent-customer calls, aiming to review interactions rather than only a sampled subset, and surfaces signals such as buying intent, objections, sentiment shifts, and engagement levels. From these signals it generates personalized, real-time coaching guidance for reps during conversations and quality-and-compliance insights that help managers make faster decisions. Agaton evaluates sales skills like objection handling, closing technique, rapport building, and negotiation, and integrates with existing tools in the sales stack including dialers, CRM, Teams, Slack, and email. The company positions Agaton as an autonomous AI co-worker that automates core workflows so reps can focus on relationships and closing. As a European company, Agaton emphasizes European data-privacy standards, GDPR compliance, ISO 27001 certification, and automatic redaction of personally identifiable information. It was founded in 2024 and reports a customer base that includes Nordic enterprises. It is a newer, regionally rooted alternative to large US-based conversation intelligence incumbents. Pricing varies by plan. Check the official website for current pricing.

Celeste AI is a Brazilian voice AI and transcription platform that specializes in Portuguese, particularly Brazilian Portuguese, while also processing audio in additional languages such as English, Spanish, German, Italian, and French. Originally known for automated audio-to-text transcription that the company positions as far more efficient than manual transcription, Celeste AI has expanded into a broader suite that includes a Meeting Assistant (Assistente de Reunião) and AI Notes (Notas de IA), alongside transcription and quality-monitoring offerings. The platform uses machine learning speech models tuned for Portuguese and is offered both as an on-demand service and via an API, so users and businesses can transcribe content as needed. Its on-demand model lets customers pay only for the hours they actually use by purchasing credits, with flexible subscription plans available for those who have recurring transcription needs. As a Brazilian company connected to local institutions such as FGV Ventures and the São José dos Campos technology park, Celeste AI is oriented toward the Brazilian market and Portuguese-language workflows, and it reports a growing user base. The service is currently operating, with a functioning login, demo requests, and support, and is suited to professionals and companies that need accurate Portuguese transcription and meeting documentation.
