Work / AI SaaS / Live

AI proposal generator SaaS for agencies

A multi-tenant SaaS that turns a client brief and an agency's past work into a structured, on-brand proposal draft.

Problem

Agencies rewrote similar proposals from scratch for every lead, and quality depended on who had time that week.

Objective

Produce a strong first draft in minutes that reuses each agency's own case studies, pricing and tone.

Solution

  1. 01

    Each agency uploads past proposals and case studies into its own isolated workspace.

  2. 02

    A brief form collects scope, budget and deadlines; retrieval finds the most relevant past work.

  3. 03

    The model drafts the proposal section by section in the agency's template, and every section can be regenerated or edited.

  4. 04

    Usage-based billing covers model costs, and the tenant's data is never shared between workspaces.
