Wintura is an AI-powered proposal and SOW engine built for service businesses that bill against scope. Marketing agencies are the wedge. The horizon is every business that quotes work.
Marketing agencies don't lose deals because their work is worse — they lose to faster turnaround and sharper follow-up. Wintura compresses brief-to-proposal from days to minutes and adds deal intelligence on top: section-level read tracking, win/loss patterns, and AI-recommended revisions for at-risk proposals. We built it so agencies stop competing on who can format a doc fastest and start winning on the actual work.
Researching the prospect. Drafting scope. Building timelines. Rebuilding the pricing table for the third time this month. Formatting the doc so it looks like the agency actually cares. Most of those hours are unbillable. Most of them happen on Friday night.
The first proposal a prospect sees usually wins the deal. So the agency that replies in five hours beats the agency that replies in five days — even when the slower agency is the better fit.
Wintura collapses that entire workflow into a single action. Paste the brief. Get a complete branded proposal — scope, deliverables, timeline, pricing, SOW — in about five minutes.

Addressable agency market
A client message should become a structured proposal in one action — not in a five-day relay between sales, ops, and design.
Same engine, different prompts. SEO retainers, video shoots, and law firm fee letters all run on the same primitive: brief → contract → invoice.
The system learns your agency’s tone, pricing defaults, and past wins. Each generated draft sounds more like you than the last.
Cutting-edge AI on battle-tested infrastructure. The interesting work is the workflow, not chasing infra trends.
Email, RFP, or three lines of meeting notes. Wintura reads it and infers project type, scope, and pricing posture.
Executive summary, scope, deliverables, timeline, pricing tiers, and SOW — branded with your logo, fonts, and color palette automatically.
TipTap-based rich-text editor. Adjust any section. Lock pricing. Add change-order terms. Your draft, refined.
Branded web link or PDF. View tracking. One-click conversion to invoice when accepted. Secure online payments built in.
Wintura is designed first for small-to-mid-size marketing agencies — 3 to 15 employees, offering services like SEO, PPC, social media, web design, branding, and content. The system has agency-specific domain knowledge baked in: it understands what a six-month SEO retainer looks like, what PPC management deliverables include, and how to structure pricing tables that win clients.
The same primitive — brief → structured contract → invoice → payment — works for any business that bills against deliverables. Design studios, video producers, consultants, freelancers, architects, accountants, contractors. Same infrastructure, different prompts.
Wintura runs on cutting-edge AI models specifically tuned for agency proposal generation. Unlike generic AI chatbots, the system has agency-specific structure baked into every generation — section ordering, deliverable scaffolds, pricing patterns. Drafts arrive structurally complete, not a wall of paragraphs you have to reformat.
Data is encrypted in transit and at rest. Client information is never shared with other users. Payments are processed through PCI-compliant infrastructure. Files live on enterprise-grade encrypted storage. The database is a production-grade relational engine with continuous backups and point-in-time recovery.
