Smartly.io vs Cust (formerly AskToSell)

Smartly.io helps businesses create, launch, and optimize digital advertising campaigns across multiple platforms. It automates campaign assembly, creative production, and budget optimization using AI to improve efficiency and performance.

What sets Smartly.io apart is its Smartly Synapse AI orchestration layer, which integrates creative and media workflows deeply. This coordination enables teams to launch campaigns faster and optimize them continuously based on real-time data and business context, unlike many tools that treat creative and media separately.

The platform supports major advertising channels such as Meta, TikTok, Google, Amazon, Pinterest, and Snapchat. It offers scalable creative production, automated quality assurance, predictive planning, and continuous optimization agents to maximize return on investment. Additionally, Smartly.io provides 24/7 human support, onboarding, managed services, and creative assistance to help teams succeed.

Smartly.io is designed for agencies, brand marketers, performance teams, and creative professionals who want to streamline workflows, reduce manual work, and improve campaign results. Its AI-driven automation and unified interface help users manage multiple client accounts and scale messaging across platforms efficiently.

By combining creative intelligence with media performance, Smartly.io enables advertisers to deliver personalized, high-impact ads that connect with audiences and drive better outcomes across channels.

Cust deploys AI Retention Agents that monitor your entire customer portfolio for churn risks and expansion signals. Each agent connects to your CRM, email, calendar, and data sources to deep-research accounts continuously. It drafts retention actions you can review and run in one click, from QBR briefs to renewal proposals. The product evolved from AskToSell, which originally focused on autonomous small-deal sales automation.

Where platforms like Gainsight and ChurnZero expect months of implementation and rigid if/else automation rules, Cust positions itself around adaptive, goal-based retention agents steered with plain language. The homepage contrasts legacy customer success platforms that need consultants and certification courses with one-click actions that go live the same day. You connect data and get a prioritized portfolio newsfeed rather than another dashboard with surface-level health scores.

Customer success managers and retention engineers who manage hundreds of accounts but can only give real attention to their top tier are the core audience. Cust targets teams trying to increase net revenue retention without hiring more CSMs per account. Plans scale from 100 protected customers on Foundation to 500 on Growth, with unlimited seats on every tier.
