Nomi.ai: The AI Companion tools

June 11, 2025Proofs.io, accessible at proofs.io, is an AI-powered platform that builds proof-of-concept (PoC) apps and integrations tailored to your tech stack, helping sales engineering teams close deals faster by showcasing real-time solutions. As a sales engineer often stuck juggling custom demos and tight deadlines, I used to spend days coding PoCs or coordinating with dev teams. Proofs has slashed that effort, delivering functional prototypes in hours that impress clients. Let me share why this tool has become my deal-closing secret weapon and why it’s a must for anyone in sales engineering looking to streamline their workflow.
The platform is straightforward: connect your tech stack via proofs.io, describe your PoC needs—say, a CRM integration or app demo—and the AI agents generate a working prototype with secure, sandboxed code. I tested it by requesting a PoC for a client’s Salesforce integration with a custom dashboard. In under two hours, Proofs delivered a clickable demo that mirrored their workflow, helping me seal a $50K deal in record time. Web sources describe it as “AI agents building proof-of-concept apps and integrations on top of your stack” (proofs.io), and I agree—it’s like having a dev team on speed dial. X posts praise its speed for enterprise sales
What’s got me hooked is its precision and flexibility. Proofs supports complex integrations across CRMs, APIs, and databases, using open-source SDKs for secure coding sandboxes. For a recent pitch, I built a PoC for a logistics app integrating with Zapier and Slack, and the AI handled API calls flawlessly, cutting prep time by 80%. The platform’s no-code interface lets non-technical reps tweak demos, while its enterprise-grade security (SOC 2 compliance) ensures client data stays safe Pricing isn’t public, but web hints suggest a subscription model with tiers for PoC volume. Compared to enso’s broader automation focus, Proofs excels at sales-specific PoCs, though enso offers more admin task agents (enso.bot).
Proofs isn’t just for sales engineers like me. Pre-sales teams, solution architects, or SaaS startups can use it to demo integrations, validate concepts, or onboard clients. I shared it with a colleague who created a PoC for a healthcare client’s HIPAA-compliant app, speeding up their sales cycle by 30%. Its strength lies in rapid prototyping and stack compatibility, but highly bespoke systems may need manual tweaks, per web reviews . A reliable internet connection is crucial for its cloud-based setup.
Proofs.io has made demo-building feel like a superpower, not a grind. It’s fast, secure, and delivers PoCs that win clients.
