A studio product, shipped end-to-end into a vertical we believe in.
The AI front desk for US sauna installers. A purpose-built agent — tuned to each installer's catalog, service area, and build process — qualifies homeowners around the clock, books site visits to the calendar, and feeds a built-in CRM and quote engine with a branded customer view. All from a workspace shaped to how installers actually work: small crews, field-heavy days, no dedicated sales seat.
The Problem
Inbound leads die between dinner and Monday.
Sauna Scale is the first product the studio has shipped to market under its own banner. The decision to bet on this vertical wasn't accidental. US sauna installation matches the Cymba Labs thesis exactly: operator-run businesses doing eight to twenty-five builds a year, average order value above thirty thousand dollars, running on workarounds because no vertical software fits the category.
What runs the inbound flow today: a Squarespace form that emails to one inbox, qualifying calls taken from job sites, quotes turned around in days. None of it is the operator's fault. Off-the-shelf SaaS was built for SaaS sales teams with twelve seats and a customer success org — not for a small crew that lives in trucks.
The opportunity was a software-shaped hole in a real market. The job was to build the thing that fits.
The Solution
Qualify, book, and quote — before the lead cools.
Sauna Scale is a vertical SaaS, shipped end-to-end. Multi-tenant from day one — every installer gets their own org, their own brand, their own product catalog, their own tax rates, their own knowledge base.
The intake surface isn't a chatbot. It's a tool-calling agent running on each installer's own knowledge base — service area, brands they carry, pricing posture, build process — with a real set of business-aware tools: qualify the homeowner, look up availability, book a site visit, send a quote, flag for human follow-up. A 9pm conversation becomes a structured lead with the fields that matter for an actual sauna build — project type, capacity, electrical scope, zip code, timeline, budget.
Behind the chat: a built-in CRM tuned for the rhythm of a sauna build — eight-stage pipeline, activity timeline per project, contact merge, async follow-up queue. A configurator-driven quote engine that prices a real build against the installer's catalog and labor rates. Calendar integration that books confirmed site visits without the installer touching the calendar. Stripe billing, audit logging, CSV exports — the production-grade plumbing that holds up under real operational load.
Every design call was made deliberately, including the non-features. There is no live chat takeover. Installers don't live in inboxes — when a conversation needs a human, the agent sets an honest async expectation and queues a follow-up. The shape of the product is as much about what's missing as what's there.
Currently shipping. A pilot cohort of US installers is forming now.
What it does.
Web Intake Agent
A tool-calling agent tuned to each installer's catalog, service area, and build process. Runs on a per-org knowledge base, reasons over business-aware tools (qualify, check availability, book site visits, send quotes, flag for follow-up), and is honest about being an AI assistant.
Built-in CRM
Every conversation becomes a lead in an 8-stage pipeline. Activity timeline per project, contact directory with de-dup, bulk operations, per-lead assignees, and an async follow-up queue tuned for crews who don't live in inboxes. CSV export of everything, anytime.
Configurator-Driven Quotes
Line-item pricing from the installer's catalog, electrical-load checks, per-quote tax overrides, branded customer-view link, accept/decline tracking, PDF export.
Site-Visit Scheduling
Calendar integration so the agent offers real availability and books confirmed appointments without the installer touching the calendar. Cal.com today; GCal and Outlook on the way.
Per-Tenant Branding
Logo, color, and business name carry through to the customer-facing quote view. The homeowner never sees Sauna Scale — they see the installer's brand.
Production-Grade Foundations
Multi-tenant Postgres with RLS, Stripe billing, audit logging, CSV exports, Sentry monitoring, usage metering. Built to hold up under real operational load.
