Built for the Long Term

When you're building wealth across decades, you need tools that help you see where you're heading—not just where you've been.

The Problem

After building a portfolio across multiple private fund commitments, the same frustrations kept surfacing:

  • GP updates were chaotic: Documents arrived in different formats at different times. Keeping everything organized and up-to-date was constant work.
  • Excel required constant manual updates: Each new statement meant updating multiple sheets, consolidating across funds, checking formulas. Version control was a mess.
  • New opportunities required full model updates: When a new fund or direct investment opportunity came in, you needed to update the entire model to validate your liquidity profile and see the portfolio impact.
  • Couldn't see where you were heading: Marks came in 6-9 months late. Hard to know where you'd land in 3-5-10 years, when you could commit again, what your true position was.

The manual work wasn't just tedious—it prevented strategic thinking. When you're buried in updating spreadsheets, you can't focus on the real questions: Which managers should we back? What's our liquidity profile? How do we build this portfolio strategically?


The Insight

The real problem wasn't data entry—it was that you couldn't answer forward-looking questions:

"Where will we land in 3-5-10 years?"

With marks coming 6-9 months late, you're making decisions based on stale data. You need forward-looking projections to see where your portfolio is actually heading.

"When can we commit again?"

Understanding your liquidity profile over the next 1-2 years is critical for planning. Capital calls and distributions are uncertain—you need forecasts, not just current cash balance.

"What if we do this deal?"

When opportunities arrive, you need to model impact immediately—allocation shifts, liquidity needs, concentration risk. Waiting 3 days to rebuild your Excel model means missing opportunities.


What We Built

Nagare started as an internal tool to solve these specific problems:

Forward-looking projections: Start with latest marks, project to current using fund-level assumptions, see where you'll land in 3-10 years.

Instant scenario modeling: Add hypothetical commitment, see portfolio impact immediately. Answer IC questions while you're still in the meeting.

Liquidity forecasts: Know your cash position quarterly for the next 2 years. Understand when you have capacity to commit.

The Change

"First IC meeting after building this: someone asked 'Should we commit $5M to this manager? What's the impact?' I answered in 30 seconds instead of saying 'give me 3 days.' The room went quiet. That's when we knew this needed to exist for other people facing the same problems."

From Internal Tool to Platform

After building this for our own portfolio, word spread. Other family offices were hitting the same walls.

So we rebuilt it as a proper platform—multi-currency support, Monte Carlo simulations, document extraction, real-time scenario modeling. Everything we wished we had when we started.

Today, family offices use Nagare to see where their portfolios are heading and plan commitments strategically instead of guessing.


Why "Nagare"?

The name captures the core philosophy: portfolio intelligence should flow continuously, adapting to new information in real-time.

In Japanese, 流れ (nagare) means "flow" or "stream"—water that moves naturally, finding the path of least resistance. It's a concept from Zen philosophy: don't force things, let them flow.

Traditional portfolio management fights against the flow: quarterly batch updates, manual data entry, rigid Excel models. Nagare works with the flow: continuous updates, automated data extraction, flexible scenario planning.
