About Partner

Black Umbrella AI builds and deploys AI voice agents for businesses that are tired of leaky pipelines, missed follow-ups, and no-shows killing their ROI. We specialize in end-to-end Retell agent setup for companies that want production-grade calling infrastructure without the DIY learning curve. What makes us different: we come from the marketing side of the table, not just the engineering side. Our founder has 10+ years in direct response and has managed over $50M in ad spend across 30+ verticals, so we don't just build agents that talk, we build agents that convert. Every Retell deployment we ship is engineered around pipeline velocity: more conversations, better qualification, faster booked calls. Our agent setup service includes voice and prompt engineering, objection handling frameworks pulled from real sales floors, full integration with GoHighLevel, n8n, and your existing CRM stack, plus post-launch testing and optimization. We offer both done-for-you builds and white-glove training for teams that want to run agents in-house.

Tempo Flows
TempoFlows - Voice AI Infrastructure Engineering TempoFlows builds and operates production Voice AI systems for companies that can't afford demo-grade deployments. We specialize in the hard part of Voice AI: integrating agents into the telecom and business infrastructure organizations already run — SIP trunks, legacy PBXs, contact center platforms, CRMs, and custom backends — rather than asking them to replace it. We build on Retell AI as our core conversation platform, and our engineering depth extends across the full deployment stack: Twilio, Telnyx, Asterisk, FreeSWITCH, and SIP signaling (including warm transfers via SIP REFER); CCaaS environments like Genesys, Five9, Talkdesk, and Amazon Connect; and business systems from Salesforce and HubSpot to Stripe, Calendly, and fully custom APIs. Our work ranges from AI receptionists and outbound qualification agents to white-label, multi-tenant Voice AI platforms with usage billing and client dashboards. Every deployment ships with the discipline of real infrastructure: staging environments that mirror production, eval and regression suites before launch, and monitoring, alerting, and versioned changes after it. We serve healthcare, legal, insurance, home services, financial services, contact centers, and BPOs — industries where calls carry revenue and compliance weight, and where escalation to a live human has to work flawlessly. Companies come to us when they need Voice AI connected to systems other vendors called too complicated. Website: tempoflows.com · Contact: hello@tempoflows.com
