What is Decagon?
Decagon is an enterprise AI customer experience platform. Companies use it to build, test and scale AI agents across chat, email and voice. Its signature concept is Agent Operating Procedures (AOPs): workflows written in natural language that describe how the agent should handle a process, which Decagon says lets teams iterate without engineering sprints.
Around the agent, Decagon offers testing and QA, live A/B experimentation, analytics and insights, a monitoring product called Watchtower, and AI-generated knowledge suggestions. Its customer list includes large brands such as Deutsche Telekom, American Airlines, Delta, Chime, Duolingo, Square, ClassPass and Ticketmaster, and retail and consumer brands such as Rituals, Fanatics and Hunter Douglas.
Where Decagon is strong
- Proven at very large enterprise scale across regulated and complex industries.
- Voice agents alongside chat and email.
- Mature tooling for testing, experimentation and quality monitoring.
- AOPs give operations teams a readable way to define complex workflows.
Things to consider
- Pricing is not public; you go through a sales process and custom contract.
- It is a horizontal platform, so ecommerce-specific flows like product discovery and cart recovery are something you design rather than get out of the box.
- Messaging channels like WhatsApp and Instagram are not highlighted on its site.
What is Manifest AI?
Manifest AI is an agentic AI platform for ecommerce and retail brands. With Agent Studio, brands build their own AI agents without code and deploy them on the storefront as an AI shopping assistant, on WhatsApp, Instagram and email, and in post-purchase flows such as order status, returns and WISMO.
Manifest agents are built to sell and support. They help shoppers find and compare products, recommend upsells and recover abandoned carts, then answer FAQs, track orders and handle returns after purchase. Brands report up to 90% ticket automation, and the company reports that its AI shopping assistant improves conversion rates by 20-45%.
Manifest also offers AI Voice Calling for human-like, multi-language cart recovery calls, Campaign Manager for WhatsApp, email, SMS and Instagram, an omnichannel support inbox with automated routing and closure, and AI search for Shopify. More than 500 brands use the platform, and its sister product BIK runs the WhatsApp experience for LEGO India.
Where Manifest AI is strong
- Built only for ecommerce, so shopping and post-purchase use cases are the starting point, not a custom project.
- Sales and support in one agent.
- Native WhatsApp and Instagram, plus voice calling and campaigns.
- No-code Agent Studio, so brands can launch in about two weeks rather than months.
- Transparent starting price for SMB and mid-market brands.
Things to consider
- SOC 2 and ISO 27001 certified and GDPR compliant, with regular third-party penetration testing.
- Focused on ecommerce and retail; if you also need agents for banking, travel or telecom-style support, a horizontal platform may suit you better.
Key differences
1. Ecommerce-specific vs horizontal
Decagon serves airlines, fintech, telecom, consumer apps and retail with one flexible platform. Manifest is purpose-built for online stores, with product discovery, recommendations, cart recovery and order flows designed in from the start. A horizontal platform gives you more flexibility; a vertical one gives you a faster path to common ecommerce outcomes.
2. Selling, not only supporting
Decagon highlights resolution, deflection and cost metrics, and some customers report revenue from AI-handled conversations. Manifest treats selling as a core job of the agent: an AI shopping assistant on your storefront, upsell and cart recovery on WhatsApp, and voice calls to recover abandoned carts.
3. Channels
Both cover chat, email and voice. Manifest adds WhatsApp and Instagram as first-class channels, which matters for brands whose customers prefer messaging apps.
4. Time to launch and who builds
Decagon's AOPs make workflows readable, and enterprise rollouts typically involve close work with its team. Manifest's Agent Studio is no-code and designed so ecommerce teams can launch in about two weeks and make changes themselves.
5. Pricing and buyer fit
Decagon does not publish pricing and sells custom enterprise contracts. Manifest AI starts at $500/month with tiers up to enterprise, a startup plan for newer brands and a free trial. If you are a mid-market brand, Manifest is likely the more accessible option; if you are a very large multi-line enterprise, Decagon is built for that buyer.
Why Manifest AI is the most cost-effective option
Sticker price is only part of what an AI agent costs. Per-seat and per-resolution pricing gets more expensive as conversation volume grows, and most tools leave you to build, test and maintain the agents yourself. Manifest AI is built to be the highest-ROI platform in this category: it has the lowest cost once real usage kicks in, and it includes the expert help other tools charge extra for or leave to your team.
- Lowest cost at real usage. As your conversation volume grows, your cost per conversation on Manifest AI stays among the lowest in the market, so support savings and AI-driven revenue compound instead of being eaten by usage fees.
- Bespoke, done-for-you agents. Our team builds all of your AI agents during onboarding, and keeps building new ones for as long as you are with us. Submit a request and we build it, so you do not need an in-house AI team or an agency.
- Customer support 7 days a week. Our support team is available every day, including weekends, when ecommerce traffic and support volume often peak.
- Live in about two weeks. Because we build the agents with you, most brands go live in about two weeks.
How to choose
Choose Decagon if:
- You are a large enterprise with very high support volume across complex products or regulated processes.
- You need one AI platform across many business lines, not only ecommerce.
- You want deep testing, A/B experimentation and QA monitoring with an enterprise partner.

- You need enterprise-grade agents at mid-market pricing.
Verdict
Decagon is a leading choice for large enterprises that need a flexible, horizontal AI agent platform with strong testing and voice capabilities, backed by a custom contract. Manifest AI is the stronger fit for ecommerce brands that want enterprise-grade agents built for shopping and support, live on web, WhatsApp, Instagram, email and voice, without an enterprise budget or timeline.
