A sample of engagements across healthcare, real estate, SaaS, e-commerce, legal and finance. Every system below is live in production today.
A 14-location dental group was losing a third of inbound calls to hold times and after-hours voicemails. We deployed an AI receptionist that answers in under two rings, books and reschedules directly into their practice calendar, handles insurance questions, and escalates genuine emergencies to on-call staff.
A residential brokerage generating 400+ web leads a month was reaching leads hours too late. Our system calls every new lead within 61 seconds, qualifies budget, timeline and location, books the viewing, and writes a structured summary into their CRM — with WhatsApp updates to the assigned agent.
A project-management SaaS with 9,000 customers faced a ticket queue growing 20% quarter over quarter. We shipped a RAG support agent trained on 1,400 help-center articles and resolved tickets — with citations, permission-aware answers, guardrails and a clean human handoff. Published eval: 94% answer accuracy.
A DTC home-goods brand drowning in manual order exceptions, stockouts and "where is my order" tickets. We automated fulfillment exception handling, inventory alerts, WhatsApp order updates and AI support triage across their Shopify stack — with a live ops dashboard the founder checks over morning coffee.
A boutique commercial law firm spent associate hours on first-pass contract review. Our system extracts clauses, flags deviations from the firm's playbook, drafts redline suggestions and cites the exact source paragraph for every flag — keeping the lawyer firmly in the loop.
An investment advisory firm stitched together monthly reports from nine spreadsheets. We built their warehouse, dbt models and executive dashboards, then added a natural-language layer so partners ask "which portfolios drifted from mandate this week?" and get a charted, sourced answer in seconds.
How we work
A working session on your process, tools and numbers. You get a fixed-price scope, an architecture sketch and a launch date — before paying anything.
2–3 days · freeA working proof on your real data or call flow. You hear the agent, query the assistant, or watch the automation run — and approve before full build.
Week 1Production build in your infrastructure: integrations, guardrails, evals, logging, documentation. Weekly demos, no surprises.
Weeks 1–4Go-live with monitoring from day one. Most clients stay on a care plan: tuning, maintenance and priority improvements.

The honest math
The three ways businesses actually get AI systems built — compared on what founders tell us matters.
| Freelancer | In-house hire | Clozo Agency | |
|---|---|---|---|
| Time to first launch | 4–10 weeks, if available | 2–4 months plus hiring time | 30 days median |
| Cost of first system | $10k–$40k, hourly creep | $120k+/year salary | Fixed $5k–$150k, signed up front |
| Skills covered | One person's toolkit | One role at a time | AI engineering, automation, design, QA — one team |
| If they disappear | Project stalls | Knowledge walks out | Documented handover; you own everything |
| After launch | Usually gone | Ongoing salary | Care plan from $1,000/mo, cancel anytime |
What clients say
Our AI receptionist paid for itself in eleven days. Missed calls were our silent revenue leak for years — Clozo found it, measured it, and closed it. The most concrete ROI we've ever gotten from an agency.
They didn't sell us "AI". They mapped our funnel, told us exactly which two steps were killing conversion, and built the system that fixed them. Speed-to-lead went from hours to 61 seconds. Our agents actually trust the bot's summaries.
Two vendors before Clozo failed to get our support agent past demo quality. Clozo shipped it with evals, guardrails and a deflection dashboard — 61% of tickets never touch a human now, and CSAT went up, not down.
Questions
Production AI systems: AI voice agents that answer and make phone calls, RAG assistants trained on your documents, end-to-end workflow automations, CRM implementations with AI layers, rescued and completed AI-generated apps, and data pipelines with executive dashboards. Everything is built in your infrastructure and owned by you.
Focused builds — an AI receptionist, a lead-qualification automation, a vibe-code rescue — typically run $5,000–$15,000. Larger systems like CRM migrations with AI layers or production RAG platforms run $25,000–$150,000. Every engagement starts with a fixed-price scope, so the number never moves mid-project.
Voice agents and single automations: 3–5 weeks. RAG assistants and MVPs: 6–10 weeks. CRM migrations: 8–16 weeks depending on data complexity. Our median time to first launch across engagements is 30 days.
You do — all of it: source code, workflows, prompts, data and accounts. We build in client-owned infrastructure from day one and hand over full documentation. No lock-in, by design.
Most clients continue on a care plan — monitoring, model and prompt tuning, API-change maintenance and priority improvements — typically $1,000–$5,000 per month depending on the system. You can also take it fully in-house; the handover is complete either way.
We've shipped systems for dental and medical clinics, real estate groups, B2B SaaS, e-commerce brands, legal firms, staffing agencies, restaurants and financial services. The pattern is always the same: high-volume conversations or manual workflows that leak revenue.
Yes — most of our clients are in the US, UK, UAE, Australia and Canada. Delivery is fully remote with 4–6 hours of daily overlap for US and UK time zones, native-English communication and a weekly video walkthrough of everything shipped. You'll never chase us for an update.
A freelancer is one person and one skill set; an in-house AI hire costs $120k+ a year and takes months to recruit. With Clozo you get the full team — AI engineer, automation specialist, designer, QA — at a fixed price, with a documented handover and no single point of failure. A typical first system costs less than three months of an in-house salary.
We build inside your own cloud accounts with least-privilege access, sign NDAs by default, support PII redaction before any model call, and keep every prompt, dataset and log in infrastructure you own. Nothing is ever trained on your data without written consent.
The ones you already run on: GoHighLevel, HubSpot, Salesforce, Dynamics 365, Zoho, Cal.com, Calendly, Twilio, WhatsApp Business API, Stripe, Shopify, Slack, Google Workspace, Notion, Airtable — plus any custom REST or webhook API. If it has an API, we've probably automated it.
