Marian Kamenistak · For companies
A mentor on site for your whole leadership bench
Your engineering managers learn the job by trial and error. The errors run on your payroll: a mis-hire here, a quiet senior resignation there, a quarter lost to a re-org that didn't need to happen.
Mentor in residence flips that. Your company gets me as its dedicated mentor for a quarter. I block onsite days, open my calendar to your people, and your leaders book 1:1 sessions the way they book a meeting room. No program to run, no cohort logistics. One PO.
3,662 sessions since 2019. Average session rating since 2024: 9.17/10.

How it works
Pick the cadence
One or two onsite days a month, for one quarter. Each day holds 6 sessions of 60 minutes.
Your leaders book directly
They get a private booking link into my calendar. No approval chain, no HR middleman. The EM with the burning problem books Tuesday 10:00.
I come to your office
Sessions run onsite, face to face. Between days, mentees ping me async when they are stuck.
You see themes, not transcripts
End of quarter you get a readout: the patterns across sessions, the org-level risks, what to fix next. What an individual said stays in the room.
Who books the slots
Anyone in your org who leads people or direction. The same onsite day often serves a director rehearsing a hard conversation and a first-time EM drowning in 1:1s.
Companies whose leaders I mentor
Engineering leaders at Ataccama, Jablotron, and Eurowag already work with me 1:1. Mentor in residence takes the same work onsite: a fixed monthly rhythm, an open calendar, and slots your whole leadership bench can book.


Why me

Ex-VPE at Mews (Series C). Advisor to Manta (acquired by IBM). 3,662 1:1 leadership sessions since 2019. Average session rating since 2024: 9.17/10. Founder of the 3,300+ member Engineering Leaders Community.

Pricing
10,332 EUR for the pilot quarter, one PO. The session rate does not move: 18 sessions at 395 is 7,110 EUR, the same rate one leader pays buying alone. The residence is 3,222 EUR on top, itemised, and it buys the onsite days, the exec readout and the dashboard. A residence day is 6 bookable sessions and your leaders fill the calendar. Individual packages live on the 1:1 pricing page. Sponsoring three to five leaders without the onsite days? That is the engineering leadership program: One-quarter packs at the same rate, free sessions on top.

Pilot quarter
10,332 EUR
per quarter. One onsite day a month, 18 sessions over 3 months.
- 18 sessions at 395, the same rate a single leader pays on the pricing page: 7,110 EUR. The residence is 3,222 EUR on top, and it is a separate line on the invoice.
- 9,299 EUR through the AI door (10% off).
- Quarterly readout for the sponsor: the themes across sessions, the org-level risks, what to fix next.
- A dashboard you can forward upward. Who booked, how many sessions, which themes came up, how your leaders rated them. Not what anyone said.
- A session your leader rates under 7/10 isn't charged. Renew or stop at quarter end.
- One PO, zero program management on your side. Async access for everyone who booked a session.
Two days a month
20,664 EUR
per quarter. Two onsite days a month, 36 sessions over 3 months.
- For orgs with 10+ leaders, where one day fills by Wednesday.
- 14,220 EUR of sessions plus 6,444 EUR of residence. 18,598 EUR through the AI door.
- Same guarantee, same quarterly commitment, double the capacity.
Prices without VAT. Invoiced against your PO. The under-7/10 guarantee is the same one on the pricing page.
Put it against the alternative: losing one burned-out director costs you six to nine months of their fully loaded cost before the replacement is productive. A pilot quarter costs 10,332 EUR. One prevented resignation pays for the residence several times over.
Frequently asked
How much does a mentor in residence cost?+
One onsite day a month costs 10,332 EUR per quarter. That splits into 18 bookable sessions at the standard 395 rate (7,110 EUR) and the residence itself (3,222 EUR): the onsite days, the quarterly readout for your exec team, the sponsor dashboard, and a calendar your whole bench shares. Two days a month is 20,664 EUR per quarter. 10% off through the AI door. Prices without VAT. Individual packages live on the pricing page, at the same 395 per session.
What does the company get to see?+
A quarterly readout of themes: what your leaders struggle with, which risks repeat across teams, what to fix at org level. Individual sessions stay confidential. Leaders speak freely or the sessions are worth nothing.
Who from our org should book the slots?+
Anyone leading people or direction: engineering managers, directors, staff engineers, product managers, first-time team leads. The same day often serves a director rehearsing a hard conversation and a new EM drowning in 1:1s.
What if our people don't book the slots?+
Slots that stay empty on an onsite day convert to remote sessions later in the month. And if the quarter shows your org doesn't need the cadence, you stop at quarter end. That's why it's quarterly, not annual.
Do you come onsite outside Prague?+
Yes. Onsite is the point of the model. Prague and anywhere in Czechia or Slovakia is simple. Elsewhere in Europe we agree logistics on the intro call.
How is this different from a workshop or a fractional engagement?+
A workshop trains a group on one topic. Fractional means I own a problem inside your org. Mentor in residence is 1:1 depth across your whole leadership bench, on their problems, at a fraction of either price. When the sessions surface an org-level issue, we scope that separately: a productivity audit, a Leadership Academy cohort, or fractional.
For companies
Build the inquiry with my AI, in 10 minutes.
The wizard asks what a good first session would ask, then sends a formal itemized offer and the brief your leaders' first session starts from. Companies sponsoring 3 or more leaders unlock free sessions on top, which I confirm on the call. The 10% AI-channel price applies to Mentor in Residence too: €9,299 a quarter instead of €10,332.
Start with one quarter
Residence quarters run with the calendar: January, April, July, October. One intro call with the sponsor, one PO before the quarter opens, and the calendar goes live for your people on day one.
The other option is the one already running: your leaders keep learning by trial and error, and the errors keep billing your payroll.
