We are living through one of those periods now. Money is one of those institutions. The first financial revolution was double-entry bookkeeping. The second was the joint-stock company. The third was the modern central bank. The fourth is the convergence of programmable money, artificial intelligence, and globally accessible markets — and it is happening now. Fourth Turning Partners exists to invest through this transition. The firm treats AI not as a marketing label but as core research and implementation infrastructure. It treats risk management as the central discipline, not an afterthought. And it treats transparency as a feature, not a compliance burden. ## Strategy — four disciplines, one liquid fund AI Research & Implementation. Fourth Turning Partners builds and operates AI systems for signal discovery, execution, and portfolio construction. AI is research and engineering, not narrative. Financial Markets. The firm invests across digital assets, options, futures, and equities. The fund is open-ended and liquid by design. Risk Management. Position sizing, drawdown control, and explicit scenario analysis are the spine of the strategy — not an overlay. AI Safety. Capital allocation to autonomous systems demands rigorous evaluation, monitoring, and override. The firm treats safety as part of the alpha. Fund vehicle. The Modern Revolution Fund LP is a Delaware limited partnership and the investment vehicle for the strategy. It holds a highly liquid book with a 90-day initial lockup and a 14-day withdrawal period thereafter. Interests are offered under Rule 506(c) of Regulation D to verified accredited investors only. ## Approach — The Evolution of Financial Institutions The Approach section anchors the firm in a long timeline of financial institutions. Each of the prior revolutions reset how capital is organized: - 1494 — Double-entry bookkeeping. - 1602 — The joint-stock company. - 1694 — The modern central bank. - Now — The convergence of programmable money, artificial intelligence, and globally accessible markets. You are here. Operating principles for investing through the transition: - Treat AI as core research and implementation infrastructure, not a marketing label. - Risk management is the central discipline of the strategy, not an afterthought or overlay. - Transparency is a core feature of how the fund is operated, not a compliance burden — limited partners see positions, methodology, and exposures. - The firm exists to invest through the Fourth Turning transition, with meaningful general-partner capital alongside limited partners on the same terms.

Working paper · under review. Author: Timothy Darrah, Mangrove Technologies / Vanderbilt University. SIEVE is a learned representation of technical indicators that predicts, without running the backtest, whether a trading strategy will trade at all and whether it will be profitable. It was trained on 1.1 million backtests across 63 assets and 136 indicators. It achieves 0.976 AUC on the trade/no-trade task and identifies 83.5% of historical strong-winner strategies. Deployed as a pre-filter inside the firm's research pipeline, SIEVE has cut backtesting compute by 64.3% across 1.24 million production runs while retaining approximately 95% of winning strategies. Preprint forthcoming on this site. Mangrove Memory — Cognitive-science-grounded memory for AI agents. Working paper · under review. Author: Timothy S. Darrah, Vanderbilt University. Mangrove Memory is an architecture that gives AI agents memory that does not degrade with use and does not require an LLM call every time it is read. It is grounded in the cognitive science of human memory rather than the engineering convenience of vector stores. A formal ontology drawn from Knowledge Space Theory sits as middleware in the conversation loop, the agent never operates the memory system directly, and memory surfaces through automatic activation rather than deliberate query. Consolidation runs offline between sessions, on the same logic that makes biological memory consolidate during sleep.
