Short answer
V12 Labs is a senior build team that develops custom AI agents for companies of 5 to 100 people. We start with one scoped workflow in intake, finance ops, support, or sales follow-up, and build the agent plus the approval queue and dashboard you need to run it. You see weekly demos on your real data, a person approves actions involving money, customers, and contracts, and you own the code.
What we build
| Workflow | Input | Finished output |
|---|---|---|
| Intake | Calls, forms, emails | A qualified lead or case with a next step |
| Finance ops | Supplier invoices | An approved, coded entry in your books |
| Support | Tickets and inbox messages | Triage, drafted replies for review, escalations |
| Sales follow-up | New leads, stalled deals | Drafted follow-ups and CRM updates for approval |
These are workflow types, not client results.
How a build works
- Free 30-minute call. We map one workflow and you get a written agent plan, scope, timeline, and price range.
- Scope in writing. One input, review step, and finished output; systems, approvals, and exclusions listed.
- Collect real examples, including messy and edge cases.
- Build in your stack with integrations, the approval queue, and logging.
- Weekly demos on your data, including failure cases: bad input, duplicates, and a broken connection.
- Go live with approvals on, then adjust rules once you've seen it work.
- Ownership: you own the code. Ongoing maintenance is agreed in the written plan.
What needs approval
| Action | Default |
|---|---|
| Moving money or posting to the books | Approval required |
| Sending messages to customers | Approval required (drafts first) |
| Contract or pricing changes | Approval required |
| Low-confidence decisions | Sent to a person, not guessed |
| Reading and summarizing | Runs without approval |
What's logged
- Every input received and its source
- Each decision and the reason or warning shown
- Every proposed action, approval, rejection, and edit, with who and when
- Results returned by connected systems
Custom agent vs platform vs freelancer
| DIY platform (Zapier, Make, n8n, Lindy) | Freelancer | V12 Labs | |
|---|---|---|---|
| Who builds | You | One person | Senior team |
| Approvals | Available on several platforms (e.g. Zapier, Lindy); you configure them | Varies | Designed into the workflow |
| Systems | Platform's connectors | Varies | Built for your systems, if reachable |
| Code ownership | Platform-hosted | Varies by contract | You own it |
| Best when | Steps are fixed and you can maintain it | Small, well-defined task | One finished workflow with review built in |
When not to hire us
- Your workflow is fixed steps between standard apps: use Zapier, Make, or n8n.
- A packaged tool already fits your process.
- You need a company-wide AI strategy rather than one working workflow.
Proof
- Accounting rebuild for a leading U.S. cemetery and funeral services company: business-critical accounting app moved from Electron to the web (case study).
- VocalDesk: AI phone agents, code public (case study, GitHub).
Neither is a measured agent-savings result; we don't claim one.
FAQ
What does a custom AI agent developer actually deliver? A working workflow in your systems: the agent, integrations, an approval queue, and logs. You own the code.
How much does custom AI agent development cost? We don't publish prices. The free call ends with a written price range for your workflow. Our cost guide explains what drives the price.
Do I own the code? Yes.
What size companies do you work with? Teams of about 5 to 100 people with a concrete, repeated manual job.
What if the agent makes a mistake? Consequential actions wait for approval, low-confidence items go to a person, and every action is logged so mistakes can be traced and corrected.
