12 Best Close Alternatives & Competitors (2026)

Siemens offers grid-scale storage controls through its Spectrum Power suite with advanced simulation capabilities. Strengths include enterprise-scale SCADA integration, though it trades Zitara's lightweight on-premise algorithms for heavier full-system deployment suited to transmission-level operators.

Fluence delivers grid-scale energy storage systems with integrated software for asset optimization and market participation. Its strengths include turnkey hardware-software bundles and global project experience, but it focuses more on full EPC delivery than Zitara's narrow on-premise signal correction. Pricing is typically project-based and higher for complete systems; it suits operators wanting end-to-end solutions rather than bolt-on BMS improvements.

HubSpot CRM offers a free core platform with marketing automation, email tracking, and pipeline tools that integrate tightly with inbound marketing. It suits growing teams blending sales and marketing. Versus Close, HubSpot provides weaker native calling and no equivalent to Chloe's autonomous lead qualification via phone. Its freemium model appeals to budget-conscious users, but Close delivers stronger out-of-the-box sales communication for teams prioritizing calls and SMS.

Zoho CRM delivers affordable, feature-rich sales management with telephony integrations and AI assistants. It targets cost-sensitive businesses across industries. Relative to Close, Zoho's AI is more assistive than autonomous like Chloe, and its calling features often depend on add-ons. Close emphasizes real-time conversation automation in one inbox, whereas Zoho may suit teams already using other Zoho apps but needing more setup for seamless dialer use.

Outreach is a sales engagement platform focused on sequences, cadences, and analytics for high-volume outreach. It integrates with existing CRMs. In contrast to Close, Outreach lacks an all-in-one CRM with native pipeline and Chloe-style AI that acts independently. Close combines engagement and CRM updates in one place, making it more suitable for teams wanting fewer tools, while Outreach excels for enterprises managing complex multi-channel sequences.

Freshsales provides an AI-powered CRM with built-in phone, email, and chat features aimed at fast-moving sales teams. It includes predictive scoring and automation. Against Close, Freshsales has solid calling but lacks an AI agent that independently qualifies and books meetings end-to-end. Close's Chloe offers more proactive pipeline action, while Freshsales may appeal to users wanting lower costs and quick setup without heavy AI conversation handling.

Monday Sales CRM brings customizable workflows, dashboards, and automation within the monday.com work OS. It appeals to teams wanting visual project-style sales tracking. Compared to Close, monday.com has lighter native calling and no dedicated AI sales agent for lead qualification calls. Close delivers stronger conversation-centric features, while monday.com suits users needing broad work management alongside sales pipelines.

Pipedrive focuses on visual pipeline management with straightforward deal tracking and automation rules. It is popular among small to mid-size sales teams that want simplicity. In comparison to Close, Pipedrive offers limited built-in calling and lacks an AI agent that proactively calls leads and updates records. Close provides deeper native communication tools, while Pipedrive may require more integrations for similar calling and SMS capabilities.

Salesloft offers sales engagement with cadences, calling, and coaching tools that integrate into CRMs. It targets revenue teams scaling outreach. Versus Close, Salesloft does not include built-in CRM pipeline management or an autonomous AI agent like Chloe. Close provides tighter integration of communication and CRM actions, suiting smaller teams, whereas Salesloft may benefit larger organizations already using separate CRMs for engagement layering.

Stem provides AI-driven energy storage optimization through its Athena platform, emphasizing automated market bidding and behind-the-meter use cases. It offers strong cloud analytics and financing options but relies more on aggregated fleet data than Zitara's cell-level on-premise accuracy. Best for commercial sites seeking subscription simplicity versus Zitara's industrial focus on rack balancing.
