Aloware

Aloware is an AI-powered contact center platform specifically designed for sales and support teams that operate within a Customer Relationship Management (CRM) system. By integrating calling, SMS, AI voice agents, a power dialer, and automation into a single platform, Aloware enhances productivity for teams using popular CRMs like HubSpot, Salesforce, Pipedrive, Zoho, and GoHighLevel. This comprehensive solution allows representatives to focus on selling rather than getting bogged down with administrative tasks like logging calls or chasing missed leads. Targeting a diverse range of industries, Aloware is utilized by over 1,000 teams across sectors such as SaaS, real estate, insurance, financial services, staffing, solar, home services, and legal. The platform is particularly beneficial for teams with 10 to 500 seats, especially those transitioning from basic calling solutions like Kixie, Aircall, JustCall, Dialpad, and RingCentral. These teams often seek a more robust system that combines AI capabilities, CRM depth, and compliance features, which Aloware provides seamlessly. What sets Aloware apart from its competitors is its unique "pickup stack." This includes features like NumberGuard, which monitors caller ID reputation in real-time; Branded Calling, which displays the company name and logo on the recipient's screen; and Local Presence, which automatically matches area codes. While many competitors may offer one of these features, Aloware integrates all three, enhancing the chances of successful connections. Additionally, Aloware's native CRM intelligence ensures that every interaction—be it a call, text, or voicemail—is automatically logged to the appropriate contact, deal, and pipeline stage, significantly reducing the time reps spend on CRM administration. Aloware also leverages AI throughout the entire sales cycle. The platform includes AI Voice Agents that can manage inbound qualification and booking around the clock, while the AloAi Text Bot qualifies leads via SMS. The Power Dialer efficiently sequences through CRM lists, and AI Call Summaries, sentiment analysis, and trending topics are automatically recorded and integrated back into the CRM after each conversation. This eliminates the need for separate AI vendors or additional engineering resources, streamlining the entire process. Compliance is another critical aspect of Aloware's offering. The platform manages A2P 10DLC registration, is SOC 2 certified, and includes features like PII redaction in transcripts and Do Not Contact (DNC) management, ensuring that compliance challenges that often hinder deployments with other vendors are effectively handled. With pricing starting at $30 per agent per month, Aloware provides a scalable solution for teams looking to enhance their sales and support capabilities while maintaining compliance and efficiency.
