Getting in touch
The calendar opens when an engagement rolls off.
We run three active engagements at a time. A slot typically opens every ninety days as one concludes. Introductions from prior clients, or from engineers whose commits we've reviewed in person, are how the next slot gets filled. Cold outreach is not read.
If you are a past client
You already know how to reach us. Use the same channel as last time. If you want to refer someone, send the introduction through a warm email from your side and we will prioritize it ahead of the queue.
If you are a prospective client
Next slot opens when a current engagement rolls off — we watch that date more closely than our own calendars. If somebody you trust has worked with us, ask them to forward the shape of your problem in a paragraph. A three-person practice that runs sales calls has stopped being a three-person practice. Our informal rule: we will read any introduction from an engineer whose commits we have reviewed in person.
If you are an engineer who wants to collaborate
We do not hire. We occasionally partner with other small practices on engagements that sit slightly outside our core — usually involving a specialized database, a regulated industry, or a platform we respect but do not ourselves operate. If that sounds like you, the introduction route applies equally: we trust referrals from engineers whose work we already know.
Current status
Q1 2025
Fully booked. Three active engagements: a ledger extension continuation, a telemetry engagement entering cutover, and a new fintech assessment in weeks one of two.
Q2 2025
Fully booked. Multi-quarter continuation plus one new healthtech engagement under signed letter.
Q3 2025
One slot under consideration. Introductions welcome through existing clients.
Q4 2025
Planning phase. Priority given to multi-quarter continuations.
The fortnight between 15 December and the first Monday in January we do not start new assessments — every previous attempt has produced a risk register we then had to rewrite in February. Warranty questions on active engagements: one business day. Everything else: after the annual retro.
What to include in an introduction
When someone refers you, the most useful thing they can send is a short paragraph about the shape of the problem and the measurement that tells you it is a problem. "Ledger is slow" is hard to act on. "Ledger p99 is 1.8s at payroll peak, roof at ~400 postings/sec, team has tried twice to rewrite and backed out" is enough for us to know within a day whether we are the right fit.
