Decagon is an AI agent that talks to your customers. FellowHire is a Support Engineer fellow that lives in your team's Slack or Teams and helps your support staff. Different jobs. Here is the honest comparison.
You want to make your existing support team faster — not replace them. You need a fellow that drafts replies, writes KB articles, summarizes tickets, and helps reproduce issues from inside Slack or Teams. Your humans still own the customer conversation.
You want an AI agent talking directly to your customers, resolving tickets end-to-end, and deflecting 50% or more of your incoming volume. You have the scale, the content, and the risk tolerance for customer-facing AI.
Decagon handles the front line — routine tickets that never need a human. The Support Engineer fellow helps your humans on the tickets that do get through. Different sides of the same desk.
| Capability | FellowHire | Decagon |
|---|---|---|
| Who it talks to | Your support team, inside Slack or Teams | Your customers, inside chat, email, or voice |
| Primary job | Helps the team do support work faster | Deflects tickets by handling them end-to-end |
| Where it lives | Slack and Microsoft Teams | Customer-facing channels (chat widget, email, voice) |
| Output | Drafted replies, KB drafts, ticket summaries, repro steps | Resolved customer conversations, escalations to humans |
| Setup time | About a week to build the fellow | Multi-week implementation with content ingestion and tuning |
| Pricing | Predictable annual per fellow | Enterprise sales-led; usage and outcome-based components |
| Best fit team size | Small to mid-market support teams | Mid-market to enterprise CX operations |
| Whole team usage | Yes — any teammate can ping the fellow | N/A — Decagon is customer-facing, not internal |
| Customization | Custom-built per customer on your stack and tone | Configured per brand on Decagon's platform |
| Tool integrations | Helpdesk, KB, code repo, monitoring, internal docs | Helpdesks, e-commerce, CRM, knowledge sources |
| Replaces a human agent? | No — supports the agent | Yes — that is the explicit goal |
| Action capability | Multi-step internal workflows | Customer resolution workflows |
| Knowledge depth | Trained on your support playbook and team voice | Trained on your KB and policies for customer-safe answers |
| Risk profile | Drafts go through humans before customers see them | Customers see AI output directly; high care needed |
| Security posture | Pilot-stage; SOC 2 on roadmap | Enterprise-grade, built for customer-data scale |
| Best for | Teams that want a junior support engineer in Slack | Companies that want to deflect 50%+ of incoming tickets |

Decagon stands on the customer side of the wall. It talks directly to your end users, deflects tickets, and escalates the hard ones. The value is measured in deflection rate and resolution speed.
FellowHire stands on the team side. The Support Engineer fellow helps your humans handle the work that comes through — including the tickets Decagon would escalate. It drafts replies, summarizes threads, writes KB articles, and helps reproduce bugs. Different sides, different value.
Decagon is built for support orgs measuring deflection rates and contact volume in tens of thousands per month. The buyer is a VP of CX or Head of Support at a mid-market to enterprise company looking to contain costs by resolving tickets without humans.
FellowHire is built for the small or mid-market support team where every teammate is wearing three hats and the bottleneck is internal capacity, not customer self-service. The buyer is a support manager who needs their team to handle more tickets without burning out. Both are valid problems. Just different.
Decagon implementations take real time because you are giving an AI agent the keys to talk to your paying customers. Content has to be vetted, escalation paths designed, edge cases tested, and brand voice dialed in. That care is necessary and we respect it.
FellowHire takes about a week because the fellow lives inside the team and a human still reviews anything customer-facing. Lower-risk rollout, faster first value. Your team starts using the fellow on day one without worrying about what a customer might see.
Customer-facing deflection at scale, mature analytics on conversation outcomes, the ability to resolve a real share of tickets without a human touching them, and the operational maturity to run that safely. If your job description includes 'reduce ticket volume by 50%', Decagon is a strong choice.
The enterprise security and compliance story is also mature. When you are putting AI in front of paying customers, that matters. Decagon has invested there and it shows.
Internal team support without the risk of AI talking directly to customers. Custom-built per role, predictable annual pricing, and fitting a sub-100-person company. The Support Engineer fellow helps a small team punch above its weight without taking the AI-talks-to-customers risk before they are ready.
The risk profile difference is real. With the fellow, a human always reviews the output before a customer sees it. With Decagon, customers see AI output directly. For teams that are not ready for that leap, the fellow is the safer starting point.
No, not directly. The fellow lives in your team's Slack or Teams. It drafts replies for your agents, writes KB articles, summarizes tickets, and helps reproduce issues. Your team still owns the customer conversation.
Decagon handles the front line — deflecting routine tickets so they never reach a human. The Support Engineer fellow helps your humans on the tickets that do reach them. They cover different parts of the desk.
No, it is a different product. Decagon is a CX platform sold to support leaders who want deflection. The Support Engineer fellow is a teammate sold to support managers who want their staff to ship more in a day. Same word 'support', different problem.
Decagon is enterprise sales-led, with components tied to volume and outcomes. FellowHire is annual per fellow. For a small or mid-market team, FellowHire's pricing is more predictable. For a large CX operation, Decagon's outcome-based math may pencil better.
Probably the Support Engineer fellow. At your volume, putting an AI agent in front of customers is a heavier lift than the deflection rate justifies. A fellow that helps your existing team handle 800 tickets faster is the cleaner ROI today. Revisit Decagon when your volume crosses 5,000 a month.
