From Prompts to Agents: Orchestrating AI Across the M&A Workflow

The first wave of artificial intelligence in mergers and acquisitions was conversational. An analyst posed a question, a large language model produced an answer, and the value of the exchange ended there. This mode of use is genuinely helpful, yet it mirrors the limitations of a single skilled colleague working in isolation: capable within one turn of dialogue, but incapable of carrying a task across the many stages, tools, and data sources that a real deal demands. The next wave is different in kind rather than degree. It replaces the isolated prompt with the orchestrated agent — a system that plans, calls tools, consults data, and hands intermediate results forward until an entire workstream is complete.

Agents vs. Prompts

What distinguishes an agent from a prompt? A prompt is a request for a single response. An agent is a goal pursued across multiple steps, with the ability to decide which action to take next, to invoke external resources, and to revise its approach as new information arrives. In an M&A context, the difference is consequential:

·        A prompt can summarize a management presentation. An agent can ingest the entire data room, extract the financial exhibits, reconcile them against the information memorandum, and flag every discrepancy for human review.

·        A prompt can draft one outreach message. An agent can maintain a target long list, enrich each entry with ownership and financial signals, sequence outreach, and update the pipeline as replies arrive.

·        A prompt can explain a valuation method. An agent can build the model, populate it from the twin of the target, run the sensitivity cases, and produce the exhibit set that supports an investment committee decision.

The architecture that makes this possible rests on three components. The first is a planner that decomposes a high-level objective — for example, "prepare a preliminary financial due diligence pack" — into an ordered sequence of subtasks. The second is a set of tools the agent may call: document parsers, spreadsheet engines, market and company databases, and increasingly, the connectors that data room and deal management platforms now expose. The third is a memory that preserves context across steps, so that a fact established early in the process remains available and consistent later. Where any of these three is absent, the system degrades back toward a clever but forgetful assistant.

For small and midsize M&A boutiques, the strategic implication is that competitive advantage is shifting from access to information toward the ability to orchestrate it. Databases, filings, and market intelligence are broadly available. What remains scarce is the disciplined coordination of many narrow capabilities into a coherent, auditable process. A boutique that assembles reliable agent workflows can conduct a first-pass diligence, a preliminary valuation, and a competitor scan in the time a traditional team would spend on scheduling alone.

Two cautions deserve emphasis. First, orchestration multiplies both speed and error. An agent that misreads a figure early in a chain will propagate that error through every downstream step, so validation gates and human checkpoints are not optional refinements but structural requirements. Second, agents are only as good as the boundaries drawn around them. A well-scoped agent that owns one workstream end to end is far more valuable than an ambitious system asked to run the entire deal without supervision.

Conclusion. The move from prompts to agents is the move from answering questions to running processes. For M&A practitioners, the opportunity is not to replace judgment but to industrialize the repetitive, multi-step work that has always surrounded it. The firms that learn to orchestrate — carefully, with validation built in and scope clearly drawn — will convert AI from a novelty into infrastructure.
