Roemer Capital for Platform Economy

Building Networks that Scale

Unlock the network effect with strategic capital structuring. Building a platform is the hardest business model to start, but the most valuable to finish. We help B2B/B2C platforms demonstrate "winner-takes-all" potential before they reach critical mass. We model the "flywheel effect" financially, proving to investors that today's high burn rate is purchasing an unassailable defensive moat for the future.

Our Approach

The Challenge: The "Cold Start Problem" and Monetization Lag

Platform businesses face a notorious "Cold Start Problem." You need to subsidize the supply side to attract demand, or vice versa, leading to long periods of negative cash flow before the "network effect" kicks in. Investors love the end state (monopoly) but hate the journey (burn). They often pressure platforms to monetize too early, killing the viral loop, or they lose patience with the "investment phase" before the moat is established.

Our Solution: Modeling the "Flywheel" and Unit Economics at Maturity

We build financial models that visualize the "Viral Coefficient" and "Network Density." We separate "Growth Burn" (marketing) from "Liquidity Burn" (subsidies), showing investors that the latter is a temporary investment in ecosystem health. We demonstrate the non-linear relationship between user growth and value—showing how each new user decreases acquisition costs or increases monetization potential, mathematically proving the inevitability of the flywheel.

FAQs

Still have questions? Book a meeting and let's talk.

How do you prove "network effects" in Excel?

We model the relationship between user count and key value metrics (e.g., match rate, time-to-fill). We show that as the network grows, the KPIs improve automatically, proving a "positive feedback loop."

Do you work with tokenized ecosystems (Web3)?

We analyze each case individually. If there is a solid underlying business model alongside the tokenomics, we can structure the equity/token warrants to appeal to institutional hybrid funds.

What is the biggest red flag for platform investors?

High churn on the supply side (Disintermediation). We help you structure your data to highlight supply-side retention and "lock-in" features to prove the stickiness of your ecosystem.

How do you determine "Take Rate"?

We model the elasticity of your take rate. We help you justify your rake to investors by comparing it to the value you provide (trust, insurance, convenience), benchmarking against industry standards (e.g., Airbnb vs. Uber).

Do you help with "Chicken and Egg" funding strategy?

Yes. We often advise splitting the raise: a smaller round to prove geographic liquidity in one city/niche, followed by a larger "expansion round." We help you define the KPIs for that first "Atomic Network."

Can you model B2B Marketplaces?

Yes. B2B often has longer sales cycles but higher AOV. We focus the narrative on "Workflow Automation"—showing how you stick to the enterprise workflow, not just facilitate a transaction.

How do you handle "GMV vs Revenue" confusion?

We never hide behind GMV. We present a clear waterfall from GMV to Net Revenue to Gross Margin. This honesty sets you apart from founders who try to trick investors with inflated top-line numbers.

Do you work with developer platforms (API economies)?

Yes. We model "Developer Share of Mind." We track metrics like API calls growth and "Time to Hello World" as leading indicators of future enterprise adoption.

How do you value data generated by the platform?

Data is an asset. We help you articulate the "Data Network Effect"—how the aggregated data from your platform allows you to build better recommendation engines / AI products that no competitor can match.

What about "Managed Marketplaces"?

If you take on more operational work (identifying, vetting), your margins drop but trust increases. We help you model the trade-off to find the "sweet spot" that maximizes LTV without destroying scalability.
