Funds and syndicates
You want portfolio companies or prospective deals to validate demand, sharpen product direction, build MVPs, or create first traction.
Proof Engine works with partners who bring access, capital, distribution, clients, domain insight, or ecosystem reach. We help turn that advantage into validated opportunities, buildable products, and commercial motion.
The best partnerships do not start with a vague idea to "collaborate." They start with a specific opportunity, a clear hypothesis, and a shared path to proof.
Partner work fits a few distinct profiles.
You want portfolio companies or prospective deals to validate demand, sharpen product direction, build MVPs, or create first traction.
You have access to founders, builders, technical talent, or domain experts and want a structured way to turn insight into venture or product opportunities.
You own client relationships or GTM access and need product, engineering, AI, or validation depth to expand the value you can deliver.
You have customers, ecosystem reach, data, infrastructure, or distribution that could support new products, internal tools, or market-entry bets.
The strongest partnerships pair real market leverage with proof-first execution. Here is how the two sides usually combine.
| Offer | Best for | Typical output | Typical shape |
|---|---|---|---|
| Portfolio Proof Program | Funds, syndicates, accelerators, communities | Repeatable support for validation, MVP, GTM, and traction across portfolio companies | Program |
| Co-Build / Joint GTM Partnership | Partners with access, distribution, or client demand | Shared opportunity, product build, GTM plan, commercial model | Partnership |
| Market Entry Proof Program | Partners entering a new market with existing advantage | Market proof, ICP, partner and channel tests, entry recommendation | Program |
| Dedicated Product Squad | Partners needing recurring execution capacity | Product, engineering, AI, GTM, and operations support | Retainer / squad |
Partner work should always start with discovery. The first step is to understand the opportunity, each side's contribution, decision rights, access, commercial expectations, legal constraints, and whether the right structure is a portfolio program, market-entry program, dedicated squad, or co-build partnership.

What we do:
Outputs:
Portfolio support often stops at advice and introductions. This program gives partners a practical execution layer that can help companies make sharper product and GTM decisions. Open the Portfolio Proof Program
A partnership model for opportunities where Proof Engine and a partner combine product, engineering, market access, and GTM execution.
Use when:
What we do:
Outputs:
Some opportunities are strongest when one side brings market leverage and the other brings proof-first product and GTM execution. This offer makes that collaboration explicit.
Partnership structures should match the risk, effort, upside, and control on each side. The default assumption is paid work. Alternative structures can be discussed only when the opportunity is specific, the partner contribution is material, and the path to value is clear.
How we run proof: methodology. Examples: case studies.
Partnership is a poor fit when the shape of the opportunity is still vague. It is probably not the right path when:
Start with the specific opportunity and what each side brings. We will help you find the right structure.
If you would rather talk it through before sending a brief, book a short routing call and we will point you to the right next step.
