HireEva vs Microsoft 365 Copilot (2026)

HireEva

by ElectricSheep, Inc.

Microsoft 365 Copilot

by Microsoft

Pros

• ✓Done-for-you setup in 24 hours with no technical work by the owner: ElectricSheep connects inbox, calendar, CRM, invoicing, and messaging apps and trains Eva on the owner's voice within one business day.
• ✓Each customer runs on a dedicated VPS with AES-256 at rest and TLS in transit, the owner's own LLM API keys stay encrypted with no vendor access, and the privacy policy states customer data is never used to train AI models.
• ✓Persistent cross-channel memory of every client interaction across WhatsApp, iMessage, SMS, email, Slack, and voice, so replies carry context that tools resetting between sessions cannot reproduce.

Limitations

• –No third-party security certifications: the SOC 2 and ISO 27001 cited in the privacy policy belong to infrastructure provider Hetzner Cloud, not to ElectricSheep, and no HIPAA BAA is offered.
• –Very early stage with no independent validation: founded in 2025 with no G2, Capterra, or ProductHunt presence, which makes due diligence hard when handing an external agent your client communications.
• –Steep gap between tiers: Biz covers up to 3 users at $495 per month, and the next step is CoBrain at $995 per month for 10 seats, leaving teams of 4 to 9 without a mid-range option.

Pros

• ✓Built into the Microsoft 365 apps people already use, Word, Excel, PowerPoint, Outlook, Teams and OneNote, and grounded in the organization's own emails, files, meetings and chats through Work IQ, with existing Microsoft 365 permissions applied to every answer.
• ✓Covers quick questions and delegated work in one product: Chat for fast answers, Agent Mode for multi-step edits inside Word, Excel and PowerPoint, and Cowork for tasks that run end to end, with Auto choosing between OpenAI and Anthropic models.
• ✓Admin controls for usage-based features: Cowork, Code and Autopilot stay off for enterprise customers until an admin creates a spending policy, with budgets, alerts and per-user caps set in the Microsoft 365 admin center.

Limitations

• –Requires a Microsoft 365 subscription: the Business add-on needs an eligible Microsoft 365 Business plan of up to 300 users, and the enterprise license needs a qualifying Microsoft 365 plan, so the Copilot price is paid on top of that license.
• –Long-running work is billed separately: Cowork, Code, Autopilot and frontier models run on usage-based Copilot Credits rather than inside the per-user license, so total cost depends on how much delegated work a team runs.
• –Several of the newest capabilities are early: Home and Code roll out first through the Frontier program, Autopilot is in private preview, and Microsoft notes that availability in Word, Excel, PowerPoint and OneNote can vary by market and licensing.
