Production LangChain agents with memory, tools, and real-world integrations that actually ship.

We work with Foster City businesses of every size — from solo operators to enterprise teams — to design and deploy AI agents that actually run in production. Not proofs of concept. Not demos that break in week two.

We've worked with enough Bay Area companies to know that cookie-cutter agent builds don't work. Every business in Foster City has unique workflows, tools, and constraints. We design around yours.

How a Foster City engagement runs

01

Discovery call

We map your workflows, understand your tools, and identify the highest-ROI agent opportunity in your business.

02

Architecture design

We design the agent: inputs, outputs, integrations, error handling, and the logic that makes it reliable in production.

03

Build and integrate

We build the agent, connect it to your tools and data, and run it through real scenarios — not sanitized demos.

04

Test and harden

We stress-test edge cases, add monitoring, and make sure the agent degrades gracefully when something unexpected happens.

05

Deploy and hand off

We deploy to production, set up alerting, and train your team to manage and iterate on the agent going forward.

Questions from Foster City clients

How long does it take to build and deploy an AI agent?

Most simple agents (single workflow, clear inputs/outputs) are live in 1–2 weeks. More complex agents with multiple integrations or multi-agent architectures take 3–8 weeks. We'll give you an accurate timeline after our first call.

What happens if the agent breaks after you deliver it?

We include a 30-day stabilization period in every engagement. If something breaks, we fix it. We also set up monitoring and alerting so we catch issues before you do. Post-stabilization support retainers are also available.

What does an AI agent actually cost to run?

Most agents for small-to-mid businesses cost $50–$300/month in API and infrastructure fees depending on volume. We design for cost efficiency from the start and show you expected running costs before we build.

Do you work with small businesses or just enterprises?

Both. We've shipped agents for solo operators, 5-person startups, mid-market companies, and enterprise teams. The scope and stack differ, but the outcome — reliable automation that saves time — is the same.
