What membership is

Four things, held together by trust.

Crucible isn't a course you finish or a feed you scroll. It is a standing set of rooms — small enough to be honest in, run for long enough that the relationships actually compound.

PILLAR I Every month

The Monthly Room

The same eight leaders, every month, with a trained facilitator. No agenda but the ones you bring — the reorg you're dreading, the report you can't reach, the number you can't say out loud anywhere else.

CADENCE — 2 hours, monthly, the same 8 for a full year
PILLAR II Once a year

The Annual Retreat

Three days, off the record, no laptops and no performance. It is where a useful peer group becomes a group of people you'd take a 2am call from — and the single thing members say they'd protect first.

FORMAT — 3 days · travel included in membership
PILLAR III Always on

The Back-Channel

A private Slack of all 280 members. Ask a real question — a comp band, a vendor, a board dynamic — and get answers in minutes from people who solved it last quarter. Not opinions. Solutions, with the numbers.

NORM — median first reply under 14 minutes
PILLAR IV Curated

The Archive

A small, deliberately un-bloated library: the best essays on the actual job of engineering leadership, plus anonymized notes from past rooms on the problems that recur. Edited down, never padded.

SIZE — ~140 pieces · roughly 2 added a month
Yusuf Abara
FOUNDER · FACILITATOR
Who built it

It started as a dinner for twelve people.

Yusuf spent a decade as a VP of Engineering — first at Cinder, then at Forecast, through its scale from 60 people to 1,400. The job, he'll tell you, is lonely in a specific way: surrounded by people, accountable to all of them, and able to be fully honest with almost none of them.

So in 2019 he started a standing dinner for eleven other engineering leaders he trusted. No deck, no agenda — just the conversation you can't have with your CEO, your reports, or your board. It quietly became the most useful two hours of his month.

Crucible, since 2022, is that dinner made deliberate and made to scale — without losing the thing that worked. The rooms stay at eight. The membership stays curated. And Yusuf still reads every single application himself.

How it actually works

The mechanics, in full.

Annual membership · no lock-in
capped at 280, always
01 How your room of eight is formed +
New members are matched by stage and situation, not job title — so your room holds people running orgs of a roughly similar size and shape, with no direct competitors and no reporting lines between them. You can flag anyone you'd rather not share a room with, no reason needed. Most rooms stay together for a full year before reshuffling.
02 What a monthly session looks like +
Two hours, video, with a trained facilitator who keeps it honest and on time. The format is simple: each member gets the floor for a real problem, and the room works it — not with advice-giving, but with the questions and the lived experience that move it forward. One member calls it "the only meeting I never reschedule."
03 The annual retreat +
Three days, once a year, in one place — most recently a quiet property outside Santa Fe. It is deliberately under-programmed: a few facilitated sessions, long meals, and a great deal of unstructured time, because that is when the real conversations happen. It is strictly off the record, and travel and lodging are included in your membership.
04 The back-channel, and its norms +
The Slack is organized around questions, not chatter — a small set of channels, a strong norm of answering specifically and concretely, and zero tolerance for selling. Members share real compensation data, real vendor experiences, and real board dynamics, because the room is closed and everyone in it has something equivalent to lose.
05 Renewing — or leaving +
Membership is annual, and that's the whole commitment — there is no multi-year contract and no penalty for not renewing. When a member leaves, between jobs or simply because the season has changed, their seat opens for the next intake. That rotation is the only reason new seats exist at all; the cap of 280 never moves.
By the numbers

Small on purpose. Sticky as a result.

280

active members — a hard cap, held since the first full year.

28

months of average tenure — members renew, and keep renewing.

12

retreats hosted since 2022 — regional gatherings included.

14%

of applicants are offered a seat — to keep the rooms right.

280 leaders. One closed back-channel.
From the rooms

Why members stay.

Hana Suzuki
VP Engineering · Brightwave
"I joined the month I was promoted into a job nobody had prepared me for. My room of eight has now watched me through two reorgs and one layoff I genuinely did not see coming. I would not have done those well alone."
◆ MEMBER 34 MONTHS · ROOM 09
Daniel Okafor
CTO · Linnea
"I've been in three of these groups. The others were networking with a recurring calendar invite. Crucible is the only one where I've actually picked up the phone at 9pm — and had someone who'd been through that exact thing pick up."
◆ MEMBER 41 MONTHS · ROOM 02
Ines Calderón
Director of Eng · Mercury
"The back-channel alone is worth the fee. I asked a question about a thorny compensation problem at 11am and had four answers by lunch from people who had already solved it — not opinions, solutions, with the actual numbers."
◆ MEMBER 22 MONTHS · ROOM 17
The commitment

Light on time. Heavy on trust.

Crucible asks for a few hours a month and a real willingness to be honest in a room. That second part is the actual prerequisite.

Term
Ongoing annual membership — no multi-year lock-in
Time
~3 hours a month, plus the 3-day retreat
Who it's for
Directors, VPs & CTOs at 50–2,000-person companies
Admission
By application — reviewed by Yusuf, every one
Size
280 members, capped — rooms of 8, never larger
Trial
Attend your first room before any charge is final
Membership

One fee.
Everything in.

No tiers, no add-ons, no per-seat upsell. Membership is a single annual fee, and it covers the retreat — travel included — so the cost of saying yes is never a surprise.

Most members are sponsored by their company as a leadership-development line. We invoice your org directly if you'd prefer.

Fair questions

Before you apply.

How is this different from CTO Connection or Reforge? +

Those are excellent at what they do — conferences and courses, content delivered to a large audience. Crucible is deliberately the opposite shape. There is no curriculum and no stage; the product is a small, fixed room of peers who know your situation in detail and stay with you through it for years. Reforge teaches you a framework. Crucible gives you eight people to call when the framework meets a Tuesday. Most members keep one of those memberships and Crucible — they solve different problems.

What's the application process? +

A written application of about 25 minutes — your role and org, what you're navigating right now, and what you'd bring to a room — followed by a 30-minute conversation with Yusuf or a senior facilitator. The bar is not seniority or logo; it is whether you'll be honest in a room and generous in return. Roughly 14% of applicants are offered a seat, almost entirely to keep the rooms well-matched. You'll have a decision within two weeks.

Do members actually use it, or is it a dead Slack? +

It's a fair worry — most communities are graveyards. Two things keep Crucible from being one. First, the monthly room is a standing commitment with the same eight people, so engagement isn't optional in the way a Slack is. Second, the back-channel is small and curated: 280 members, a strong norm of answering concretely, and zero selling. The honest signals are the numbers above — 28-month average tenure and a sub-14-minute median reply — and they're the figures we watch most closely ourselves.

Can I expense this? +

Most members do. At the Director-to-CTO level, $4,408 a year sits comfortably within a leadership-development or executive-coaching budget, and it is meaningfully less than an executive coach for the year. We invoice your company directly if that's easier, and we'll provide whatever a finance team needs — a W-9, a clear scope of services, or a short note for your manager explaining what the membership is and is not.

What actually happens at the annual retreat? +

Three days, one place, no laptops and no performing. The schedule is intentionally light — a handful of facilitated sessions on the problems members raised in advance, and otherwise long meals, walks, and unstructured time, because that is when the conversations that matter actually happen. It is strictly off the record. Travel and lodging are included in membership, and members consistently name it the part they would protect first if they could keep only one.
