§ 01 · A quarterly for the working engineer

Engineering, written like it matters.

Four issues a year. Forty-seven contributors. Long-form essays on the parts of software that don't fit into a thread — incident reviews, hiring philosophies, the quiet trade-offs that shape a codebase over a decade. No sponsored posts, no SEO copy, no roundups.

“We don't write about tools. We write about the people who use them.

§ 03 · How an issue is made

Commissioned, not crowdsourced.

Every piece begins with a question we can't stop thinking about — and a writer we've been quietly reading for years. Our editors sit with each draft for an average of three weeks. There are no themes-of-the-month, no SEO calendars, no quotas. If a piece isn't ready, it doesn't ship.

Contributors are paid $0.62 per word on acceptance, plus a flat $400 kill fee if a piece never runs. Every essay is fact-checked against primary sources before publication.

Designed for the long sit.

Source Serif at 19px, measured to 64 characters, with a custom drop-cap on each opening paragraph. We typeset every piece by hand. Footnotes appear in the margin on desktop, inline on mobile, and as endnotes in print. The web edition mirrors the print edition — same line breaks, same widows, same orphans, even the kerning.

No ads. No tracking pixels. No interstitials. The page weighs 38 KB before the type loads. We keep it that way on purpose.

The bus factor was always one. We just didn't measure.

FIG. 02 — staff promotions, 2018–2026

FIG. 03 — review velocity, by repo

Notes from a year of being on-call every other week.

§ 06 · What readers say
“I cancelled my Substack stack to keep Foundry. It's the only thing I open on Tuesday mornings before slack.
— Priya Anand · Staff Engineer · Linnea
“Three essays from Issue 042 changed how we run incident reviews. Worth the subscription a hundred times over.
— Yusuf Abara · CTO · Mercury
“The closest thing to a literary magazine I've found in engineering. No newsletters compare.
— Ines Calderón · Head of Eng · Brightwave
“I pass print copies around the office. Engineers actually read them.”
— Marcus Tobin · Founding Engineer · Forecast
§ 07 · Questions answered honestly

Before you subscribe, in case it helps.

§ FAQ.01

How is Foundry different from a paid newsletter on Substack or Beehiiv?

+

We commission. We don't aggregate. Every piece is paid up-front, fact-checked, and copy-edited before it ships. There's a kill-fee. There's a masthead. There's a print run. The closest comparison is a quarterly review like n+1 or The Drift, not an individual writer's newsletter.

§ FAQ.02

Will you accept pitches from working engineers, or are pieces commissioned?

+

Most pieces are commissioned, but we open pitches every January and July for two weeks. We accept about 1 in 38 — last cycle that was 12 commissions out of 458 pitches. Pitches go to [email protected]. 250 words, two sample paragraphs.

§ FAQ.03

Is the archive permanent, or does it expire if I stop subscribing?

+

Every issue from your subscription window remains accessible to you indefinitely, even if you stop paying. We don't believe in revoking what you've already paid to read.

§ FAQ.04

Where does the print edition ship from, and is there a carbon offset?

+

Printed at Park Communications in London on FSC-certified paper, posted via Royal Mail and partner couriers. Each issue accounts for roughly 1.18 kg CO₂e per copy delivered — fully offset through a verified peatland restoration project in Caithness.

§ FAQ.05

Do you run sponsorships or accept advertising from infrastructure vendors?

+

No. 100% of revenue is from readers. We've turned down four vendor sponsorship offers in the last 14 months. If a piece mentions a tool, no one paid for that mention.

§ 08 · One last thing

Read the issue your colleagues will be quoting on Wednesday.

Subscribe before Friday and we'll mail you the Issue 046 print edition while supplies last — 312 copies remain.
