Free interactive simulator · ~3 minutes

Can you survive your first 90 days?

You were the best engineer on the team. On Monday, you became their boss. Make the calls a new EM actually faces, and see how it lands.

~3 minutes · Free · No credit card · Instant outcome
What it is

Real dilemmas. Real consequences.

Not a personality quiz. A run of scenarios every new manager recognises, with choices that ripple through the next 90 days.

01

Scenarios that actually happen

The old peer who undermines you. The release that's slipping. The PIP your manager wants started. No straw-men. Every choice is a real call new EMs make.

02

Four hidden dimensions

Every choice moves the dials on Trust, Delivery, Credibility, and Wellbeing. You won't see the scoring during the run. You'll see exactly where you spent it at the end.

03

One outcome, and a shareable card

How did it land? Real Deal? Driver? Wipeout? Get your outcome, your full breakdown, and a card you can post or save.

How it works

Three minutes from Monday morning to outcome.

1

Play through the scenarios

One dilemma at a time. Three or four plausible options each. No clearly correct answer. Same as the real job.

2

See the consequence

Every choice gets a one-line reaction. Then the next week starts. Same as the real job.

3

Get your outcome

Five possible endings. One of them is yours. Plus your full breakdown across the four dimensions, and a card to share.

I built and led engineering teams at Yelp for nearly half a decade. I write to 80,000+ followers every week. This simulator exists because most first 90 days are a series of recoverable mistakes, until they're not.

What people are actually saying.

It's never been a more exciting time to be an engineering manager. Or a more challenging one. Ryan offers a complete leadership package with insights, tools, and community support you won't get from onboarding. He's been in the EM trenches long enough to be your best guide to mastering this difficult role.

I’ve known Ryan for a long time, and if you’re an engineer stepping into leadership, or trying to do it better, you should be talking to him. He’s that rare combination: an excellent engineering manager and a genuinely great coach. He doesn’t lecture. He helps you think clearly about your situation and figure out what to do next. If you’re considering coaching to level up as a manager, I can’t recommend him highly enough.

Ryan’s work has weight. He writes about engineering management with practical clarity and hard-won judgment. Trust, feedback, ambiguity, tension, the decisions no framework can make for you. If his EM Accelerator carries the same honesty as his writing, it will be worth serious attention.

Ryan Murphy’s insights are valuable for any engineer looking to level up. Unlike many industry voices, his background as an Engineering Manager allows him to bridge the gap between technical execution and leadership.

Ryan transformed my approach to communication both upwards and to my team. He enabled me to move into roles that otherwise felt beyond my reach, and gave me a new level of confidence when dealing with superiors.

Ryan’s content feels very real and honest: actual day-to-day engineering leadership experience, not just high-level theory. I really appreciate how openly he shares challenges, lessons learned, and vulnerable moments while staying practical and relevant to what engineering managers deal with today.

I wish I’d had something like this when I made the IC-to-EM transition. It would have given me a clear framework for the different stages of leadership, how to navigate tough situations, and what to actually expect from the role. Ryan has built something that addresses the gaps no one prepares you for.
