Before the first member goes up, the structure already has stamped drawings and a signature behind it

Why can't IT deliver big projects on time like construction?

A laptop, financial reports, and cash on a desk: the numbers a deal gets weighed by.

The code that passes the pitch and fails due diligence

I talked to founders who went through technical diligence and watched the term sheet shrink — not over the product, but over the paperwork, the code's ownership, and everything nobody had read with a buyer's eyes. Why the time to fix it is long before the round.

The rule that decides commission usually lives in three places at once, with different values

Thousands of IF/THEN/ELSE rules: code, engine or spreadsheet

Rules that change weekly belong in versioned data with an owner. Rare rules stay as ifs. When a rules engine pays off, and what the finance spreadsheet really costs.

Killing a product is a strategic decision — a senior squad leads the conversation before it becomes crisis

When to kill a product: a 4-question framework for founders

Killing a product is the most-avoided strategic decision by founders. Result: capacity consumed by a product already lost — months later, a pivot that could have happened in weeks. See the 4-question framework a senior squad uses to lead the conversation.

The math behind a squad has less mystery than most proposals suggest

How much does a development squad cost in 2026?

From $12,000 to $22,000 a month, depending on team composition. That is the pricing Revin publishes on its site. Here I open up the math: what goes into a managed squad monthly fee, what the market charges in 2026, and the three questions that deflate a padded proposal.

Every software bottleneck starts small and becomes scenery. A fifty-minute deploy was never a decision, it was an accumulation.

I inherited a 50-minute deploy, and it was the best news in the audit

When Revin stepped into this client, the production deploy took fifty minutes and nobody could say why. It took me a while to see the number was not the problem, it was the symptom. Here is what was underneath, and why a slow deploy costs far more than it looks.

A crowd with hands in the air at a concert: the demand spike your product meets the day it works.

It was fast in the demo. Then the data grew.

At launch the app flew; six months later every screen crawls. It is almost never a server problem, it is code that talks to the database the wrong way. What a senior squad checks before you throw money at bigger infrastructure.

A codebase touched by seven freelancers in a row looks exactly like what it is: the same thing, written more than once.

I paid for the same feature three times. The money was the least of it

An edtech reached Revin with a three-year-old codebase and seven freelancers behind it. I went looking for one bug and found the same feature built three separate times. The duplication was not the disaster. What it was hiding was.

The word "rewrite" freezes any executive meeting — what changes is how the CTO presents it

Hard conversation: how the CTO communicates the product needs a rewrite

The word "rewrite" freezes any executive meeting. The problem is rarely technical — it is communication. See the template senior squads use to present a rewrite to CEO/CFO/board, and why managed squads execute rewrites without stopping operations.

In B2B enterprise, "ship ugly" is the most expensive Silicon Valley advice

The anti-MVP playbook for B2B enterprise: why "ship ugly" is the most expensive advice

MVP was made for B2C. In B2B enterprise, first impression is one-shot — a client who sees a raw product never comes back. Here is why senior squads ship "ready to demo" instead of MVP, and how that changes product economics.

The meeting where the proposal looked perfect: six seats, an open scope and nobody owning the delivery

I turned down a $480k contract. I'd do it again.

Last October, the biggest contract in Revin's history landed in my inbox. Six developers, twelve months, open-ended scope. I read it twice and said no. Here is what was in that proposal, why buying developer hours is the most expensive way to build software, and what happened next.

A building being torn down. The urge to level everything and start clean is real, and almost always pricier than it looks.

Why I almost never approve a full rewrite of your product

A logistics founder called me set on throwing three years of product in the bin and starting over. I spent the whole call talking him out of it. A full rewrite is the decision that looks most like courage and most often turns out expensive, and there is almost always a duller path that ships better.
