Eastern Pine Ventures / Independent venture studio

Tools for understanding markets.
A record to learn from.

Eastern Pine Ventures is an independent venture studio based in New England. We develop AI systems, research tools, and publications that help people understand financial markets and follow the stories shaping them.

Our current work centers on CoinFox, a market-intelligence publication, and FoxClaw, our private research and operations system.

  • CoinFox — market stories, evidence, and follow-up.
  • FoxClaw — private research and operations.
  • Planifier — planning, paper practice, and review.

01 / Mission

A market story is more than its latest headline.

A headline, an official release, a chart, and a discussion can offer very different accounts of the same event. Understanding the story means looking at the sources, comparing explanations, and following what happens next.

We’re building tools to keep that work connected, so each new development adds to the record rather than replacing it.

Keep what was known, what was believed, and what happened next.
  1. Observation
  2. Evidence
  3. Interpretation
  4. Decision
  5. Authority
  6. Outcome
  7. Learning

A result makes more sense when we can see the reasoning behind it: what someone observed, the evidence they used, what could have challenged their view, and how events actually unfolded. Preserving that context gives us something to learn from.

02 / Market history

A place to learn how markets work.

Financial stories, the systems behind them, and examples worth returning to. This growing archive brings together historical photographs, explanations, and source records to help make market events easier to understand.

From ticker tape to negative oil futures and next-day settlement, the aim is to follow both the market move and the mechanism behind it.

Why this history belongs here

These photographs make the work behind the market visible: the machines, the delays, the judgment, and the people keeping track of it all. That is what draws me to them.

A short market history

From the trading floor to today.

Nine moments from the archive. Each leads to a fuller explanation and the original sources.

  1. 01

    The South Sea boom and collapse

    South Sea shares surged during 1720 and then collapsed. Fortunes built on the run-up disappeared, and the crash forced a rescue and restructuring of the company.

  2. 02

    The climb to 1929 and the fall that followed

    The Dow rose about sixfold from August 1921 to September 1929. It fell nearly 13% on October 28 and nearly 12% the next day. By July 1932 it was 89% below the peak and would not regain that high until 1954.

  3. 03

    A new price for gold

    The official gold price had been $20.67 an ounce. Beginning February 1, 1934, the Treasury bought gold at $35 an ounce. That was a rise of roughly 69% in gold's dollar price and a deliberate devaluation of the dollar against gold.

  4. 04

    Markets go electronic

    Technology reduced some trading costs and helped quotes update faster, but it also gave speed a price of its own. The dot-com cycle showed the other side: the Nasdaq-100 peaked near 4,705 in March 2000 and bottomed near 805 in October 2002, a decline of more than 80%.

  5. 05

    Housing losses and the financial crisis

    U.S. home prices fell about 30% from mid-2006 to mid-2009. The S&P 500 fell 57% from its October 2007 peak to its March 2009 low.

  6. 06

    A crash measured in minutes

    The Dow's intraday decline reached 9.16%. It dropped another 573 points in five minutes, then recovered 543 points in roughly a minute and a half. Some stocks briefly traded for a penny.

  7. 07

    When oil futures went below zero

    The May 2020 WTI futures contract closed at −$37.63 per barrel on April 20. Other delivery months and oil benchmarks did not all share that price.

  8. 08

    GameStop and the mechanics behind a trade

    GameStop reached $483 intraday on January 28, then fell more than 86% by the end of the first week of February. These are contemporaneous prices reported by SEC staff, before the later stock split.

  9. 09

    A shorter wait for settlement

    T+2 became T+1 for most covered transactions: settlement one business day after the trade. This is a change in the transaction process, not a claim about an index move.

03 / What we’re building

Different roles. A shared approach.

Eastern Pine Ventures is the studio behind the work. CoinFox is the current public product focus. FoxClaw supports private research and operations. Planifier brings the same emphasis on reasoning and review to educational planning.

The story develops. The earlier record remains.

02 / Private infrastructure

FoxClaw

FoxClaw is the private research and operations system being developed at Eastern Pine Ventures. It helps the founder organize evidence, research tasks, draft material, and follow-up as information changes. Material intended for CoinFox goes through a separate editorial review and publication process.

Private / In development

03 / Planning layer

Planifier

Planifier is the educational planning side of the work: write down a thesis, its evidence, risks, timing, and what would invalidate it; practice on paper, then return to review the outcome.

Educational planning

How they connect

From research to a record worth returning to.

Research

Gather sources and preserve their original context.

Review

Check the evidence, distinguish facts from interpretation, and explain what remains uncertain.

Follow up

Keep new developments, corrections, and outcomes connected to the original account.

04 / Roadmap

Make the research useful. Then keep it useful.

Make CoinFox useful for someone following a real market story, from its first report through new evidence and eventual outcomes.

Reader pages and editorial tools are taking shape. The next steps are stronger coverage backed by sources, clearer context, and a reliable path from reviewed research to publication.

Development update: 5 October 2026. The descriptions here explain the product direction. Broader availability and participation are still being developed.

How we build

  1. Start with evidence.
  2. Test what the tools can do.
  3. Build on what works.
  4. Keep responsibility clear.
  1. NowIn build

    Make the daily reading useful

    Bring reporting, source notes, market context, and upcoming economic events into a coherent reading experience. Make dates and coverage gaps easy to see.

    For the reader: Understand a story, open its sources, and tell current reporting from an older record.

  2. NextPlanned

    Follow the story through time

    Connect updates, alternative explanations, corrections, and outcomes so readers can follow a developing story without rebuilding it from scattered tabs.

    For the reader: See what was known at the time and what was learned later.

  3. ThenPlanned

    Make participation useful

    Give readers a way to contribute original ideas, missing sources, questions, and counterevidence. Develop attribution and moderation that help those contributions strengthen the shared record.

    For the reader: Better evidence and discussion, with a clear explanation of how contributions are reviewed.

  4. LaterUnder construction

    Grow a lasting learning archive

    Keep adding financial stories, worked examples, and lessons here at Eastern Pine. Connect useful historical context with CoinFox reporting. Personal notes, search, and deeper connections are future work.

    For the reader: Clear explanations, traceable sources, and stable links that can be shared from CoinFox or elsewhere.

CoinFox is intended for research and education. It does not provide personalized financial advice, execute trades, or hold customer funds. People remain responsible for editorial decisions when AI assists the work.

  1. A clearer public focus for Eastern Pine

    CoinFox remains the main product focus. Eastern Pine is also becoming a home for financial history, examples, and lessons learned: a growing reference library that can add context to CoinFox stories.

    Direction

  2. The reader experience takes shape

    CoinFox development brought reporting, World context, Markets, a calendar, Publications, Ideas, and Lab into a connected development version of the reader experience. Content depth and broader public availability remain work ahead.

    Development

  3. Clarifying the relationship between the projects

    Eastern Pine Ventures was reframed around one connected market-reading system: FoxClaw, CoinFox, and Planifier.

    Company

  4. Defining how the systems share information

    A shared model was drafted to describe how the products can send reviewed information and outcomes back to FoxClaw while keeping responsibility for each system clear.

    Architecture

  5. The first FoxClaw idea

    The rise of agentic AI raised a question that continues to guide the work: how can a system help with complex market decisions while keeping people responsible for those decisions?

06 / Founder's note

Why I’m building Eastern Pine.

Growing up, I wanted to understand what happened inside places like the New York Stock Exchange. I was fascinated by the idea of a trading floor in the 1990s: the people, the noise, the information moving through the room, and the decisions being made in real time. That curiosity stayed with me.

My working life has been in physical jobs, including running a printing press. That work teaches you to pay attention to the whole process: the machinery, the material, the timing, and the quality of what comes out. It also made me want to build something of my own.

AI has opened a new way for me to do that. Eastern Pine Ventures is where I’m putting that opportunity to work—learning the technology, building with it, and turning that effort into tools people can use.

CoinFox is the public focus of that work. I want it to help people understand what is happening in markets, examine possible explanations, and see what the evidence supports. I want the stories to remain useful after attention has moved elsewhere.

FoxClaw supports the research, organization, and follow-through behind that effort. I’m building it to help me take on more of the work while I remain responsible for what we build and publish.

I also want Eastern Pine to become a place to keep what I learn: financial stories, examples, and old lessons that become useful again when something new happens. That archive will grow alongside CoinFox, one useful addition at a time.

I want to build a lasting company that makes something useful from this opportunity. For now, that means developing CoinFox, putting the research tools to work, and learning through the process. The direction is ambitious; the work is practical.

07 / Current stage

An independent studio, taking shape.

Eastern Pine Ventures is led by one founder. CoinFox’s reader pages and editorial tools are being developed alongside FoxClaw’s private research tools. Broader coverage, open participation, and dependable follow-up remain work ahead. The development record follows that progress as it happens.

Good research should make room for questions.
