6–12 months 2–3 months

Same rigour, a fraction of the calendar. Every step stays reviewable and every decision stays explainable, to your team and to the vendors you turn down.

2–3 months is calendar time, including vendor response windows. Your team's hands-on effort drops to hours, not weeks.

How the agents get you there.

One connected flow from first conversation to final recommendation. Every hand-off is visible, every output is editable.

1

Discovery

A conversational AI co-pilot captures your goals, use cases, current tech stack, requirements, compliance needs and budget, no static intake form.

2

Architecture

Winner analyses your stack and surfaces gaps, overlaps and risks before a single vendor is contacted.

3

Briefing

A shareable vendor briefing, exportable as a PDF, in an internal version and a vendor-facing version.

4

Shortlist

A pre-selection with a documented reason for every inclusion, and, just as important, for every exclusion. That's the trust mechanism the whole method is built around. From here, you can enrich the shortlist further, and in a coming release, trigger automated vendor outreach directly.

5

Adaptive question catalogues

Generated automatically, optimised for discrimination between vendors, and fully editable before you send them.

6

RFI / RFP

A finished RFI or RFP document. Vendors respond directly on the platform through a secure link, topic accordions, an approval workflow, and progress tracking so you always know who still owes you an answer.

7

Evaluation

A structured assessment of every response that surfaces contradictions and marketing fluff. We're also building toward evaluating recorded vendor demos, so what a vendor says live gets held to the same standard as what they write down.

8

Recommendation

A transparent, ranked recommendation with reasoning you can defend to your own steering committee, not just a score.

Data & Enrichment

Every shortlist stands on aggregated intelligence.

Winner continuously aggregates vendor intelligence from sources no buying team could track by hand, and structures it into typed, comparable evidence behind every inclusion and exclusion.

Review platforms

Verified user reviews — real strengths and weaknesses from live deployments.

Analyst positioning

Where independent analysts place each vendor in the market.

Vendor documentation

Official product docs and API specs, read and structured into capabilities.

Company & financial registers

Legal entity, ownership and funding data from official registers.

LinkedIn signals

Headcount, hiring and organisational momentum, tracked over time.

News & press

Current news, launches and market moves as they happen.

Deep research

AI deep-research runs that surface the long tail no single source holds.

Web & archives

Public web and historical snapshots for context and change over time.

One vendor profile is assembled from all of these — continuously refreshed, so your shortlist reflects the market as it is now, not a snapshot from last quarter.

Built so you can defend the decision.

Reasoning, not just a score
Every inclusion and exclusion, explained.

"Why did you exclude vendor X?" always has an answer. Shortlist reasoning is documented for every vendor, not only the ones you picked.

Human in the loop
You decide, the agent proposes.

No fully autonomous mode. Every agent output is reviewable, editable and rejectable, that's the default, not an option to switch on.

EU hosting
Hosted in the EU, GDPR by design.

Your workspace data is hosted in the EU. GDPR-compliant processing is the starting point, not a checkbox retrofitted later.

Built by people who've been on both sides of the table.

Winner comes from two founders who have run vendor selections from both ends, selling to buyers and advising them through the process. That's why the whole method is built around trust and explainability, not automation for its own sake.

Daniel Heer
Daniel Heer
Co-Founder & CEO

Daniel is the founder and former CEO of Zeotap, a global data-technology company. In that role he sat through countless RFI and RFP processes from the vendor's side, and saw first-hand how inefficient and error-prone they tend to be. As CEO of Winner, he is rebuilding those processes into what they should be: fast, transparent, and fair to buyers and vendors alike.

As one of the Managing Directors of DIGITL, a market-leading Google Marketing Platform consultancy of around 65 specialists, he has guided countless corporates and enterprise clients through highly complex CDP and marketing-automation selections. As CTO of Winner, he owns product technology and AI architecture, turning that experience into the agents that now run the selection.
