The most common thing we hear from new clients: "We thought this would take two weeks." The reality for a production-grade AI agent built right is 4–8 weeks, depending on complexity. Here is exactly what is in that timeline and what you can do to shorten it.
The Standard 4–6 Week Timeline
Discovery & Scoping
Map the existing process, identify integration points, define success metrics and acceptance criteria. Often the most valuable week — uncovers edge cases that would have blown up the build.
Architecture & Tool Integration
Build tool scaffolding: API connections, database access, authentication. Write initial system prompt. Set up eval framework. First working prototype by end of week.
Core Logic & Iteration
Refine agent behavior against real inputs. Fix tool usage errors. Add memory and context handling. Begin stakeholder review cycles.
Testing & Hardening
Run full eval suite. Adversarial testing. Edge case handling. Performance benchmarking. Add guardrails, rate limits, error recovery.
Staging → Production
Deploy to staging. Run parallel with existing process. Gather real-world feedback. Fix last-mile issues. Flip to production with monitoring in place.
What Adds Time
- Unclear requirements — the biggest schedule killer. Every round of "actually we also need it to..." adds 3–5 days.
- Integration complexity — connecting to legacy internal systems often takes 2x longer than expected.
- Stakeholder review cycles — if approvals require multiple sign-offs across departments, budget an extra 1–2 weeks.
- Regulated use cases — legal/compliance review of AI outputs can add 2–4 weeks.
How to Shorten the Timeline
The single biggest accelerator: arriving at week 1 with written documentation of the current process — every step, every edge case, every exception. Teams that do this are typically in production 2 weeks faster than those who document during the build.
Other accelerators: dedicated point of contact with authority to make decisions, pre-provisioned API credentials for all systems we'll integrate, and agreement upfront on what "done" looks like (no scope creep).
Can You Go Faster?
Yes. For a well-scoped, simple automation with no legacy system integrations and a prepared client, we have shipped in 10 business days. But "fast and cheap" always means "scoped small." If you are told you can get a complex multi-agent system in two weeks, ask what they're leaving out.
