Former SpaceX engineer reconstructs the financial execution system using first principles

The financial infrastructure project Plan Execution Lab recently announced the completion of an angel round of financing led by a well-known family office in Singapore, with a post-investment valuation reaching $50 million. This round of financing will primarily be used to accelerate the research and development and ecological construction of the PlanX Financial Execution Protocol and the Xgent Autonomous Financial Runtime.

Unlike most trading platforms, Plan Execution Lab does not attempt to create a "faster exchange" or "smarter trading robots." They seek to answer a more fundamental question: what is truly missing in future financial markets?

From SpaceX to Financial Infrastructure

The career starting point of Plan Execution Lab founder Lex Li was not Wall Street, but SpaceX. As a campus recruit engineer at SpaceX, Lex worked there for thirteen months. During this experience, what influenced him the most was not a specific technology, but the core methodology advocated by SpaceX: First Principles Thinking.

At SpaceX, engineers were constantly asked: Why must rockets be manufactured this way? Why must costs be this high? Why are the industry’s default practices necessarily correct? Many rules that were taken for granted were ultimately proven to be merely historical habits. This way of thinking became Lex's most important methodology when he later entered the financial industry.

"After entering the financial industry, I found that everyone was discussing faster trading speeds, more complex product designs, and more liquidity," Lex said. "But very few people stop to think about a more fundamental question: what is the meaning of the existence of financial markets?"

Viewing Financial Markets from First Principles

In Lex's view, the core function of financial markets is not trading, but Capital Allocation. Trading is merely a way to express capital allocation, while the real process of turning decisions into actions is Execution.

Over the past decade, financial infrastructure has undergone tremendous changes: assets have been completed on-chain, liquidity has been completed on-chain, and settlement has been completed on-chain. However, the execution layer has seen almost no fundamental changes. Today's market is still built on a large number of fragmented human workflows:

• Humans monitoring the market

• Humans scheduling funds

• Humans managing risks

• Humans coordinating liquidity

• Humans executing trades

Even on the most advanced trading platforms, financial execution remains Human-Native.

The Agent Era is Accelerating Strategy Decay

With the development of large models, AI Agents, and automated systems, the market is entering a new phase. The speed of information dissemination is increasing, the speed of market response is accelerating, and the speed of strategy decay is also quickening.

An advantage that could last for years in the past may now only last for months. Alpha that used to last for months may only remain for weeks in the future. For independent traders and even small to medium-sized institutions, it is becoming increasingly difficult to maintain effective strategies.

"The biggest challenge in the future is no longer acquiring information, but how to execute continuously and efficiently," Lex stated.

Strategy is Not the Smallest Unit

Most people think of a strategy as a standalone algorithm. But from a first principles perspective, a strategy is actually just a combination of multiple execution capabilities. For example:

• Risk management

• Capital allocation

• Liquidity acquisition

• Hedging logic

• Execution timing

• Portfolio construction

These capabilities are more like independent nodes; together they form a larger Execution Graph. Therefore, the true competition in the future financial system will not be single strategies, but Execution Networks. The most powerful financial systems in the future will not be a single mysterious algorithm, but a collaborative network built and continuously evolved by numerous execution nodes.

PlanX: Bridging the Migration from CEX to DEX

Based on this judgment, the team has created PlanX. The positioning of PlanX is not another DEX, but a Financial Execution Protocol.

The team believes that one of the biggest financial migrations in the next decade will be the global trading flow migrating from centralized exchanges (CEX) to on-chain markets. But what is migrating is not just assets, but financial behaviors themselves. The goal of PlanX is to become the execution infrastructure in this migration process, providing the market with:

• On-chain execution capabilities

• Liquidity access

• Risk management

• Settlement coordination

• Capital scheduling

Thus, building an open financial execution network.

Xgent: The Runtime of the Autonomous Financial Era

If PlanX is the execution infrastructure, then Xgent is the autonomous financial runtime built on top of it. Users no longer need to manually manage multiple platforms and complex workflows; they only need to define:

• Investment goals

• Risk preferences

• Constraints

• Capital allocation rules

Xgent will automatically complete:

• Execution logic construction

• Risk validation

• Liquidity coordination

• Strategy execution

• Autonomous optimization

The team defines this process as: Intent → Execution Graph → Verification → Autonomous Execution.

Creating a Bloomberg Terminal for the Autonomous Financial Era

Lex often uses an analogy to describe the long-term vision of Xgent. Over the past few decades, the Bloomberg Terminal has become the core operating environment of the global financial market. It not only provides data but, more importantly, it offers a unified workflow, unified context, and unified collaborative environment for the entire financial industry.

Bloomberg is the operating system of the human financial world. In the autonomous financial era, a new operating system is also needed. However, the service target is no longer humans, but Agents.

"If the Bloomberg Terminal defined the Operating Environment of Human Finance, then the combination of PlanX + Xgent hopes to become the Operating Environment of Autonomous Finance."

Financial Infrastructure Built by Nodes

Unlike traditional financial systems, Plan Execution Lab does not attempt to control the entire network by a single institution. The team believes that the next generation of financial infrastructure must be jointly built by participants. The future ecosystem will be composed of the following participants:

• Execution Nodes

• Liquidity Providers

• Strategy Contributors

• Infrastructure Operators

• Autonomous Financial Agents

Each participant contributes not a single strategy, but the execution capabilities themselves. These execution capabilities will continuously combine, evolve, and ultimately form the execution network of the autonomous financial era.

The Core of Next-Generation Financial Competition

For Lex, the core competitiveness of future finance is not who has the best trading strategy, but who has the most powerful execution network.

What has changed over the past decade is the location of asset storage. What will change in the next decade is the way financial decisions are executed. The combination of PlanX + Xgent hopes to become the infrastructure for this transformation. The future will not belong to isolated strategies; the future will belong to autonomous execution networks.
