Custom AI Agents Built for Your Business

A custom AI agent is software that can reason, decide, and act on tasks specific to a business by connecting to business tools, following rules, and operating on business data. Unlike a general chat product, it is trained, evaluated, and deployed against measurable workflow outcomes such as ticket resolution rate, document throughput, or revenue lift.

A typical Mercury Development engagement runs 8 to 16 weeks from kickoff to first agent in production. Discovery and prototype take 2 to 4 weeks. Production hardening — evaluations, guardrails, observability, and secure integrations — takes another 4 to 12 depending on system complexity and compliance requirements.

All of the above. We are model-agnostic and select the right foundation per use case — Claude, GPT, Gemini, Llama, Mistral, or fine-tuned open models running on your infrastructure. Agent design, evaluation, and orchestration are where the durable value lives, not the model choice.

We deploy inside your VPC or on-premises when required, support SOC 2, HIPAA, and GDPR-aligned engagements, and never train on client data without explicit contractual permission. Every agent ships with audit logs, role-based access, and configurable PII redaction.

Both options are supported. Most clients embed AI features into existing web, mobile, or enterprise products through secure APIs and SDKs. We also build standalone agent platforms when the workflow does not yet have a software home. See our AI Features Integration page for embedded scenarios.

Every project starts with a baseline KPI — cost per ticket, hours per case, revenue per visitor — and a target lift. We instrument the agent to report against that baseline from day one. Most clients see measurable ROI within the first quarter post-launch; we share the dashboards.

AI discovery sprints start at $25,000 and produce a roadmap, architecture, and ROI model. Production builds typically range from $80,000 to $400,000 depending on agent count, integrations, and compliance scope. Ongoing operation and evolution is billed monthly.
