Senna Research
66 → 5 · identical vials in one grid, rebuilt into five research categories

8h → 10m · to quote a demolition job
Quoting a job meant a senior estimator reading blueprints for most of a day. We built an AI takeoff pipeline from plan PDFs to a bid workbook, with a review screen for the estimator.

$4M+ · collected in its first fifteen months
Invoicing lived on a green-screen ERP and a spreadsheet. We built the customer portal, the billing app that replaced the ERP screens, and the bridge into QuickBooks — a modern layer that works with the legacy system instead of replacing it.
Read the case →MoneoOur own
5 weeks · from MVP to live, billed SaaS
Screen recording in, step-by-step SOP out. Moneo reads the pixels, not the page, so it documents green screens and legacy ERPs that other SOP tools can't see. We designed it, built it, and run it — billing, site and all.

How it works
Every ticket has a size. You pay when it ships.
We build exclusively with Claude, and Tengu Studio OS sits under every engagement. Ask in Slack, on a call or in a screen recording, and it becomes a ticket, sized in credits you approve before anyone starts. Claude Code builds it, a person reviews it, every change passes QA on a live preview, and its credits are drawn only once it's live. Humans decide. Agents carry.

Claude Codefor all of our development
- 01Ask
In Slack, on a call or in a two-minute screen recording. Tengu turns it into a ticket.
- 02Size
An AI model in Tengu sizes it, XS to L, and you approve the credits before anyone starts.
- 03Ship
Built with Claude Code, reviewed by a person, QA'd on a live preview, released to production.
- 04Pay
Credits are drawn the moment it's live. Not when it starts, not when it's “almost done”.
Nothing is bigger than an L. Bigger work is split so every piece ships on its own. Ticket sizes, a worked example and your first month in credits are on the pricing page.
