Operating with a team of 2 to 10 employees and backed by $500K in Pre-Seed funding from Y Combinator (S24) and Pioneer Fund, the company builds autonomous inbox and back-office agents that qualify replies, coordinate internal data lookups, and close transactions automatically. ### How Proxis works Proxis operates at Level 3 autonomy by combining fine-tuned, distilled enterprise language models with a full-stack workflow execution runtime. Rather than offering a standalone chat interface, Proxis embeds directly into corporate email inboxes and internal operational tools. When a prospect or customer emails a sales or operations alias, Proxis's active agents read the thread, query connected internal databases or CRM records to verify inventory, pricing, or account status, and execute the required response or transaction step without human intervention. ### Limitations Operational limitations and technical trade-offs include: - **Animated Pricing UI Transparency Friction**: On Proxis's public pricing page, per-seat dollar figures render as animated rolling digit counters (0 through 9), creating a pricing transparency bottleneck that requires prospective buyers to initiate onboarding or contact sales for exact seat rates. - **Internal Tool Integration Latency**: Connecting autonomous email agents to legacy on-premise ERPs and custom internal tools in traditional enterprises introduces initial API integration latency compared to cloud-native SaaS connectors. - **Autonomous Inbox Governance Barrier**: Allowing AI agents to send binding commercial replies and pricing quotes from corporate email domains requires strict human-in-the-loop escalation thresholds and compliance governance guardrails. ### Proxis pricing Proxis structures its commercial model around Monthly and Yearly (20% discount) per-seat tiers across Growth (for early-stage teams), Scale (for fast-moving startups, starting free at $0/seat to begin building), and Enterprise (supporting up to 5 or more active agents with custom security and sales scoping). ### How Proxis compares Within the Cold Email Sequences & Mailbox Infra and Inbox Automation category, Proxis competes against AI email and workflow alternatives such as DryMerge, Cassidy, and Lindy. Versus top-of-funnel cold email blasters like Instantly, Proxis differentiates itself by focusing on fine-tuned enterprise inbox execution and internal operational automation that carries incoming threads all the way to deal closure.
