Different Philosophies
Day.ai and harp represent two distinct philosophies about AI in sales.
Day.ai is the "AI chief of staff" approach. It captures all your conversations, auto-updates your CRM, preps you for meetings, and answers questions about your pipeline. It makes you dramatically more productive. The system of record reasons about your data so you don't have to manage it manually.
harp is the "AI sales team" approach. Instead of making you better at selling, it does the selling. Prospector, Qualifier, and Reacher handle top-of-funnel autonomously. You coach through feedback and approvals, but the execution happens without you.
AI & Autonomy
Day.ai's AI is context-aware and deeply integrated. It auto-captures emails, calls, and meetings. It builds a context graph that understands relationships between contacts, companies, and deals. Its MCP-based API lets you interact through Slack, Claude, and other tools you already use.
harp's AI is execution-oriented. The agents don't wait for you to ask - they proactively find leads, score them, and draft outreach. Maestro coordinates the entire workflow. The difference: Day.ai gives you intelligence about your pipeline. harp gives you the pipeline.
Who Should Choose What
Choose Day.ai if you have an active sales motion and want a smarter CRM that captures everything, preps you for meetings, and eliminates manual data entry. If your bottleneck is information management and meeting prep, Day.ai is compelling.
Choose harp if your bottleneck is capacity - you need more outbound, more leads, more meetings, but you don't have the people to generate them. If you want autonomous agents doing the prospecting and outreach while you focus on conversations that matter.
