The Problem

Your best people are stuck doing busywork

01
Same questions, every time
Security questionnaires ask the same 200 questions. Your team re-answers them from scratch because nobody can find the last version.
02
Senior talent wasted on formatting
Your $150/hr engineers are copying compliance text into Excel cells instead of winning the technical evaluation.
03
Deals lost to faster competitors
The agency that submits a polished proposal in 3 days beats the one that takes 2 weeks. Speed wins contracts.

How It Works

Three steps to faster proposals

1

Upload your history

Drop in past proposals, case studies, pricing docs, compliance answers, and FAQs. WinStack builds your institutional knowledge base automatically.

2

Paste the RFP

Upload the new RFP, questionnaire, or vendor form. WinStack parses every question and maps it to your best existing answers.

3

Review and submit

Get a complete first draft with confidence scores per answer. Edit the weak spots, export in the format you need, and submit days ahead of deadline.

The agency that responds fastest, wins most

Every enterprise tool in this space costs $50K+ per year and takes months to implement. WinStack is built for the agencies that actually need it: small teams doing big contract work, where every proposal is a revenue event.
