A Submarine Fire, $80K in Cash, and the Client Who Quoted California Ethics Rules at Me

A Submarine Fire, $80K in Cash, and the Client Who Quoted California Ethics Rules at Me

Mike Kimball has been a California attorney since 1995, but the most instructive professional experience of his career happened before he passed the bar. He was the officer of the deck on a nuclear attack submarine when a fire broke out under the polar ice pack, and he had about five seconds to decide whether to follow the standard procedure ... which was physically impossible ... or think his way to a different answer.

He chose the different answer. His XO chewed him out anyway. And over the next three decades, he kept applying the same framework: know your procedures cold, and know when the situation has moved past them.

How Mike Kimball Got Here

Mike served as a naval officer on the USS William H. Bates, a nuclear attack submarine, before becoming a California attorney in 1995. He worked on Yahoo's legal team during the dot-com era, when the company had more than 50 business units and legal was asked to evaluate all of them. He later served as chief legal counsel at Crux Digital, which Salesforce acquired. He has run his own practice since 2007, advising tech startups and large companies on venture capital and commercial deals.

He is also a private pilot, writes about the intersection of venture capital, technology, AI, and public policy on Substack, and has a collection of client stories that most attorneys will never have to match.

Process Versus Judgment: What a Submarine Fire Taught Him About Running a Practice

The Naval submarine service trained officers on procedures for nearly every scenario. But it also trained them on something harder to teach: how to think, not just what to think. When a procedure was designed for a situation that no longer matched reality ... such as a fire aboard a submarine that was 400 feet under polar ice with no open water to surface into ... following the procedure was not just unhelpful. It was dangerous.

Mike applied the same logic to his intake process and client relationships. He built a process, used it consistently, and also trained himself to recognize when a situation had moved past what the process was designed to handle.

For Kelley, this maps directly to what she coaches law firm owners on. A checklist or SOP is not a constraint ... it is a foundation. It tells every person in the firm what the expected path is. It also creates the baseline against which you can recognize when you need to deviate. A solo attorney handling their own intake can improvise easily, but when the firm grows and that intake process needs to be delegated, the improvisation does not transfer. The checklist does.

How Mike Identifies Clients Who Will Create Problems

A few years into his solo practice, Mike realized he was carrying clients who created disproportionate liability risk. Not necessarily malpractice risk ... regulatory risk. For a solo practicing in venture capital and commercial deals, getting entangled in a federal or state investigation, even as a tangential party, would be a firm-ending event.

He reviewed his full client list and sorted every client into three buckets: no risk, acceptable risk, and get out. What he found was that two specific patterns predicted the highest-risk clients.

The first pattern was source: clients who came through a specific personal referral tended to share that referral source's approach to shortcuts. Not all of them were fraudsters, but they did not treat regulatory compliance as a real constraint. In investment and fundraising work, that is a serious problem.

The second pattern was negotiation: clients who had negotiated his rate at the outset turned out to be his most difficult clients. Not because they were slow payers ... though some were ... but because they did not respect the legal process. A client does not have to follow every piece of advice an attorney gives. But they do need to actually hear it. The clients who had negotiated the rate tended to be the ones who heard advice and then did whatever they had already planned to do.

After identifying both patterns, Mike stopped taking referrals from the first source and adopted a firm no-negotiation policy on his rate. The rate is not high to begin with ... a solo practice does not carry the overhead of a large firm ... and any client who needs to negotiate it before the work has started is telling him something about how they will behave once the work is underway.

The $80,000 in Cash

The most striking client story Mike shares involves a call he received from a CEO and CFO who were on their way to meet a potential client and wanted to update him on a recent investment. They told him the company had received an $80,000 investment.

He asked where it was. They said it was in the CEO's desk drawer.

He thought they meant a check. It was cash.

The CEO said he planned to deposit it into his personal checking account and then write a check to the corporation. Mike told him he did not want to do that. The CEO asked why. Mike explained that depositing more than $10,000 in cash requires disclosure of where the money came from ... it is a federal requirement. The CEO said he would break it into smaller deposits instead. Mike explained that was called structuring, that it was also a federal crime, and that banks were specifically trained to identify it.

At this point, Mike asked where the money had come from. The CEO said his uncle, who lived in Ukiah ... a small city in northern California that was, at the time, well known for marijuana cultivation. The uncle was afraid of banks, which was why the money was in cash. The uncle had driven it down from Ukiah.

Mike got off the phone, wrote a resignation letter, scanned it, and emailed it before the call had been over for five minutes. The clients got upset and started quoting California's Rules of Professional Conduct regarding attorney withdrawal. Mike hired a retired state judge who practiced ethics law, worked through the withdrawal properly, and eventually the matter was resolved.

He has not checked recently, but the last time he looked, the company's website was still online, doing nothing, nearly a decade later.

Using AI to Vet Clients Before the First Call

After that experience, Mike built an intake screen using Claude. He wrote a script that runs a background check on any prospective client ... their company, their history, their public record ... and produces a summary before Mike has a conversation with them. He has not turned up any more adverse events since implementing it, but it also gives him useful context for the intake conversation itself. Knowing a prospective client's professional history allows him to ask more specific and better-informed questions from the start.

This is a specific use case that maps to what Kelley does with her own content research: using AI to gather information that would take hours to find manually, with a prompt refined over time to return consistent, useful output. The key is knowing what you need from the AI before you write the prompt, and being precise about what a useful result looks like.

Where His Best Clients Come From

Mike's client base has been built almost entirely through personal referrals, primarily from the Yahoo alumni network. When that network dispersed after COVID as people retired or changed careers, he also maintained relationships with a small number of other attorneys whose judgment he trusted and who sent him deals over the years.

He tried LinkedIn marketing for about 14 months. He did not get a single client from it. He did get a 45-minute call with the Inspector General of the Department of Energy after writing a critical piece about a company that was attempting to build a nuclear reactor buried a mile underground. The DOE wanted to discuss the fraud concerns. Nobody became a client.

His current practice is smaller and more deliberate than his early-career work. He bills at a rate that does not require him to compete with large firms, takes only work that interests him, and relies on a small number of trusted relationships to generate new clients.

One Thing to Change This Week

Kelley asked Mike what he would tell a law firm owner to change this week to run a better practice. His answer: learn to fly.

The more serious version of his advice is the same point Kelley makes about networking. Go do the things you actually enjoy. Be present in communities where you interact with other people, on terms that are not transactional. One of Mike's best clients came from a biennial flight review ... a conversation that started with "are you a doctor?" and ended with a new client relationship.

The work tends to follow the relationships. The relationships tend to follow the activities. This is especially true for solo and small-firm attorneys who are not competing on marketing spend.

Frequently Asked Questions

What are the warning signs that a prospective client will be difficult to work with?

Mike identified two patterns in his own practice. First, clients who came through a referral source whose own standards were low ... the clients tended to share the same approach. Second, clients who negotiated his rate at the outset. The second pattern was the more consistent predictor: these clients tended not to respect the legal process itself, which meant they heard advice and then ignored it. That creates liability exposure for the attorney regardless of the outcome for the client.

How can an attorney safely withdraw from a client who presents regulatory risk?

Mike's experience is a good illustration of the process. He resigned immediately, in writing, and then hired an attorney who specialized in professional ethics ... a retired state judge ... to help him navigate the withdrawal correctly under California's Rules of Professional Conduct. He did not try to manage the process himself. For an attorney who needs to exit a client relationship for serious reasons, consulting an ethics attorney before taking action is worth the cost.

How are solo attorneys using AI in their practices right now?

Mike's primary use is intake screening ... a Claude script that produces a background summary on a prospective client before the first call. He also uses AI for marketing and legal research: not to produce substantive conclusions, but to gather statutes and recent case law that he then reviews himself. He does not yet use AI to produce substantive legal work product, because he does not trust it for that purpose. The specific use cases he has automated are ones where the output is a starting point for his own judgment, not a replacement for it.

What should law firm owners know about client-rate negotiations?

Mike's observation is that clients who negotiate the rate are often signaling something about how they will treat the attorney relationship overall. His practice is a solo operation without the overhead of a large firm, so his rate is not high to begin with. A client who needs to negotiate before the work starts is telling him how they will value the advice once it is given. That pattern held consistently enough that he adopted a no-negotiation policy, and it reduced the volume of difficult client relationships.
