A private diagnostic for engineering managers

Six months in, nobody has told you how you actually lead.

LeadSim is a diagnostic you play. You take over a team of five engineers and decide everything yourself, in your own words, at your own pace. The season is text: situations land, you write what you do, five AI characters with their own agendas write back. There is no script: what happens next follows from what you just did. What comes back is a report on the patterns you fell into, evidenced by the things you actually did.

Problem 01

The one thing nobody gives a new manager is a mirror.

60^%

Gartner research, via Wharton (2024)

of new managers fail within their first two years

The same share, 60 percent, report getting no training at all when they stepped into the role (Center for Creative Leadership). Most find out how it is going late: in an exit interview, in a reorg, in a one-on-one that goes badly. Nobody tells you early, because telling you early is uncomfortable and telling you late is somebody else's problem.

Nobody

reviews how you manage, only what you ship

Two managers ship the same quarter. One built the team up getting there, the other spent it down. On paper the quarters are identical, so nobody asks. The difference arrives two quarters later, when one of them is down a senior, the rest have stopped volunteering for anything hard, and the cause is six months old and untraceable.

Invisible

blind spots that feel reasonable from the inside

Avoiding a hard conversation under deadline pressure does not feel like avoidance. It feels like protecting the team's focus. Micromanagement feels like being helpful. You cannot find these by asking yourself.

Mechanism 02

You have already read the book. Play the season.

The situations are written in advance. The season is not. Every situation you meet was authored by a person, not invented on the spot to fit you. What is not fixed is which of them reach you, in what order, and what state your team is in when they do. That part follows from what you have already done, which is why the problem that lands late in the quarter is usually something you set in motion early without noticing. You type what you would actually say, five people with their own histories react to it, and there is no answer key to look up.

01 · Experience

You're the manager. Decide.

Five engineers with personalities, opinions, and things they are not telling you. A performance problem. Scope creep. A conflict between two seniors. Someone quietly interviewing. You write what you would do, in your own words. There is no multiple choice to game. Decisions compound, nothing resets, and you can walk away between any two of them.

02 · Consequence

Every decision comes with debt.

The cost of a management decision does not land in the next standup. It lands three weeks later, in the quiet flight risk. In the senior who stops volunteering for hard problems. In the junior who learns that asking for help is expensive. Those debts are not scheduled in advance. They are opened by a specific thing you did, and they come due when they would come due in real life.

03 · Diagnostic

You leave with your own tells.

The season is only the instrument. What you keep is a report on the patterns you fell into, each one named and evidenced by the decisions that produced it, quoted back to you. Nobody else receives a copy. Play a second season in six months. A different result is the only proof of behavioral change that exists.

Two managers who both handled the outage end up with different teams by the end, for reasons that trace back to how each of them handled it. What changes between seasons is the path. What does not change is the measurement: the same behavior axes, the same named patterns, drawn from situations you have not seen before. New situations, same instrument, and the only variable left in the comparison is you.

What you learn 03

You already know what to do. Now you can see when.

Nothing here tells you how to manage. You have read the books and you have worked for good managers and bad ones, so you already know what the right move looks like written down. What you have never had is the ability to catch yourself in the act, while the choice is still open. That is what you take out of a season.

You learn

Your own tells.

Warm Deferral is not a label you get stuck with. It is a sentence you catch yourself starting. Two weeks after the season, in a real one-on-one, you hear yourself turning a no into next cycle and you stop mid-sentence. That is the whole return on this. Not new knowledge. Earlier recognition.

You learn

What it costs.

You watched a senior go quiet, then stop volunteering, then start answering recruiters. You saw which decision of yours opened that, and how long it took to come due. So you now know what week two of it looks like, while it is still a five minute conversation. You met that person before you met the real one.

You learn

Whether you actually changed.

Six months on, play it again. Same behavior axes, situations you have not seen. If the pattern is gone, it is gone from what you do, not from what you intend to do. Confidence is not evidence, and no course, book, or coach can hand you this comparison.

A page of the LeadSim private report: named management style, strengths and blind spots, each evidenced by specific decisions

Above: a fragment, one page of several. To read the whole thing you have to play a season.

None of that works if the report flatters you. So every pattern in it comes from a fixed library written before you ever played: the model selects and evidences, it never invents a name to fit you. Each one is attached to what you actually wrote and what happened next, which means you can argue with the reading but not with the record. And where a single season did not see enough to be sure, it says so, instead of filling the gap with a sentence that would have been true of anyone.

Privacy 04

Private by design.

Who sees the result

Your manager and HR, at minimum

You. That is the entire list.

When you do it

A date in someone else's calendar

Whenever you sit down. Stop and come back.

Can you tell if it worked

No. You feel more confident, which is a different thing.

Play a second season in six months and compare.

What you keep

A certificate and a book recommendation

A report on decisions you actually made

The report goes to you and stops there. No dashboards for anyone else, no aggregates, no admin view: the product is built so that a second reader cannot exist. If the person who decides your promotion could read it, you would play the version of you that promotes well, and the diagnostic would measure a performance.

The data works the same way. Seasons and reports live on our own infrastructure, run through the Anthropic API, which does not train on your data, and nobody but you reads them.

Many founding members expense the seat from a learning budget. The invoice says professional development. The report still says nothing, to anyone but you.

Behind it 05

Built by someone who has watched this fail dozens of times.

Founder · LeadSim

Michał Orzechowski

20 years in engineering · Mentor to dozens of IC-to-manager transitions

I've spent two decades inside engineering organizations watching the same scene play out: a strong individual contributor gets promoted, everyone crosses their fingers. Six months later the team is fragile, the new manager is exhausted, and nobody can quite point to what went wrong.

I built LeadSim because the gap between management theory and management reality cannot be crossed by reading. The patterns that matter: avoiding conflict under deadline pressure, treating high-autonomy people like juniors, mistaking activity for progress. They only become visible when the consequences arrive, and by then the pattern has already cost you a person, a quarter, or both.

"LeadSim is the tool I wished I had when I was promoting people who deserved the opportunity but weren't ready for the reality. It shows them how they lead."

Founding cohort 06

Thirty seats, then the price goes up.

$49. Three full seasons: your diagnostic, and two chances to prove it changed. $99 at launch, single season. Access opens September 2026, and founding members get my direct line while the diagnostic is still being shaped.

Thirty seats means I pick who gets them. Apply below, and if the fit is there we talk for fifteen minutes and you take a seat. No payment until then.

Got it.

I read every one of these myself and I will come back to you within two days. If we are a fit, the next step is a fifteen minute call and a founding seat at $49.
