Overview

Estimation is a skill. AI can learn it.

Every agency does the same thing when a new brief arrives: someone senior reads it, pulls up old project folders, and spends hours producing a number that is half art, half memory. CostLabsHQ replaces that muscle memory with a structured, calibrated, reproducible pipeline that turns a one-paragraph brief into a full proposal in 60–90 seconds.

The goal is calibration, not automation. Humans still close the deal.

Architecture

Lambda pipeline. One estimate.

CostLabsHQ runs on AWS as a fleet of Lambda functions behind API Gateway. Each Lambda owns one phase of the estimation pipeline, with a containerized worker handling the heavier Claude inference steps.

The Tiered Model

A range, not a number.

Rather than a single number (which is always wrong), CostLabsHQ produces tiers representing the range from bare-bones MVP to full-featured production launch. Each tier has a dollar window, milestone count, and risk profile. Calibration clamps keep estimates within ~15% of human-authored ballparks.

Status

Live on AWS.

CostLabsHQ is deployed and processing real estimates. Claude Sonnet cross-region inference profile. Worker container on ECR. SES email delivery with branded proposal attachments. Daily analytics digest.
