Gnbly vs Double

Gnbly is an automation studio that builds AI-native software for go-to-market, content, and operations teams. The company ships three products on a shared AI fabric: NatterGPT for voice agents, Vidsue for long-form video production, and WorkerFleet for operational automation. Each tool runs on the same models, memory layer, and security stack.

Compared with buying separate point solutions, Gnbly bundles focused products that share infrastructure. You trade a single-vendor suite for deeper cross-product memory, but each product still has its own site and pricing rather than one unified dashboard.

Gnbly targets operators at growth-stage companies who want voice, video, and workflow automation without building custom agent infrastructure. NatterGPT handles outbound and inbound calls with copilot mode, Vidsue turns scripts into publish-ready videos, and the studio reports 12M+ agent actions monthly across 40+ countries.

Double is a lead research and enrichment platform for sales and marketing teams. You upload a prospect list, and Double uses GPT to search the web and answer custom questions about each company or contact. Instead of manually Googling accounts, you define the criteria that matter to your outbound motion and get answers back at scale.

The product focuses on qualifying and enriching leads in bulk. You can ask whether a company is remote-first, SOC II compliant, B2B, building an API product, running a marketplace with payments, or shipping a mobile app as its core offer. Double returns sourced answers you can review alongside LinkedIn and email data in a table view.

Double also finds verified work emails by aggregating more than ten private data sources. The site positions this coverage as broader than tools like Apollo and RocketReach. Teams at Amazon, Indeed, and Gartner are shown on the homepage, and the company is backed by Y Combinator.
