Straight answers to the questions buyers ask before hiring an AI agent agency.
No hype — just clear, direct answers on cost, fit, and how custom agents compare to consultants and off-the-shelf tools, from the engineer who builds them.

AI agent reliability: why agents fail in production — and how to fix it

Read the answerA buyer's reference for hiring someone to build custom AI agents.
Most of the questions people send me before a project start the same way: they've seen a slick AI demo, they have a real workflow that's eating hours every week, and they're trying to figure out whether to build something custom, buy a tool, hire a consultant, or wait. These pages answer those questions directly, in plain language, so you can make the call before you ever book a call.
I've grouped them three ways. The buyer's guides explain what an AI agent agency actually does — scoping a high-value workflow, building the agent against your real systems and messy data, and managing it in production with monitoring and human review — and how to tell a real builder apart from a directory listing or a one-off demo. The comparisons weigh custom agents against the two most common alternatives: consultants who deliver advice rather than a working system, and off-the-shelf tools that win on speed until your edge cases, integrations, and accuracy requirements show up. The pricing page breaks down what genuinely moves the number and lays out my staged model — a fixed-fee scoping engagement from $5,000 that's credited toward the build, then a defined build phase, then ongoing management.
A few themes run through all of them. Custom agents earn their cost on workflows that are high-value, repetitive, and too messy for a generic tool — multi-system reconciliation, executive reporting that pulls from everywhere, document-heavy review. Reliability comes from human-in-the-loop checkpoints, monitoring, and someone accountable for the system after launch, not from a clever prompt. And the honest answer is sometimes “you don't need me yet” — if an off-the-shelf tool covers it, these answers will tell you so. Read whichever one matches where you are; if your question isn't covered, the fastest path is a short intro call.
