Scope, timeline, budget, decision signals — pulled and highlighted.
Your logo, voice, pricing pre-applied the moment a brief lands.
Pings you the moment a brief lands so you reply within the hour.

3 free proposals every month — no strings

CHANGELOG
2026-05-21
Real case studies on demo + expanded inspector
Outbound demos render real case studies pulled from your library. The inspector surfaces extraction quality scores.
2026-05-14
Tighter brief extraction
Client name + geo extraction guardrails reduced false positives by ~40%. Sample proposals now invent realistic names instead of "Sample Client".
2026-04-26
Cobalt rebrand
Wintura migrated from Burnt Sienna #C2410C to Cobalt #2563EB — high-trust electric blue, premium fintech aesthetic. design-tokens.json is now the source of truth.
2026-03-08
Onboarding fork
Post-signup flow ends in a 3-card fork: sample proposal, real proposal, or skip. No more auto-generated samples.
Start free with 3 proposals/month. Upgrade when you're ready — still cheaper than any single tool you're replacing.

Yes. Paste your client brief, select the service type, and Wintura generates all 8 sections: executive summary, scope, deliverables, timeline, pricing, terms, and next steps. Edit anything before sending.
No. Wintura learns your agency's writing style from past proposals — tone, vocabulary, and persuasion patterns. The more you use it, the more it sounds like your agency.
Manual proposals take 4-8 hours of writing and formatting. Wintura gives you a structured, branded proposal with scope, timeline, pricing table, and terms in minutes — plus a client portal, view tracking, invoicing, recurring billing, and analytics. It's speed and structure, not just writing.
Yes. Create invoices from accepted proposals in one click. Clients see a Pay Now button and can pay by card or bank transfer (ACH). Money goes directly to your Stripe account — Wintura never holds your funds. Automatic reminders go out 3 days before due date.
Monthly reports analyzing your proposal data — win rates by service type, pricing trends, client patterns, and recommendations to improve your close rate. Available on the Agency plan.
