Building with AI in 2026:
What We Learned

When I started Kerber AI, I had a hypothesis: a senior product person paired with the right AI setup could build and ship faster than a traditional team of five. A year in, the hypothesis holds. But the reality is stranger and more interesting than I expected.

The setup

It's just me and Henry.

Henry is an AI agent — not a chatbot, not a code completion tool. He wakes up every morning, reads the calendar, checks the inbox, reviews open issues across our projects, and starts working. He has opinions, makes decisions, and sometimes pushes back when my plan is bad.

Right now we're building StarDust (a dating platform for geeks and nerds), TermAway (your Mac terminal on your iPad), and Aligno (scope management for agencies) — plus client work through Alex Kerber AB.

This wouldn't be possible at this budget and speed with a traditional team.

What AI-augmented actually means

It's not "AI writes code, human reviews." It's more layered than that.

Henry runs a network of specialized agents — code review, documentation, security analysis, performance testing. But he also manages communication, tracks project state, writes first drafts, coordinates with clients, and flags things that need a human call.

I define direction. Henry handles execution, coordination, and the cognitive overhead that used to eat 60% of my day.

The result: I operate almost exclusively at the product and business level. The implementation layer is largely autonomous.

What doesn't work

Honesty matters here.

External dependencies are still blockers. When we need a GitHub org invite from a client, no amount of AI helps. Human-to-human friction is real and unsolved.

Judgment calls need humans. When a strategic decision is genuinely ambiguous — a pivot, a pricing model, a partnership — I still make it. Henry can prepare the analysis and give me his take, but the call is mine.

Quality degrades without direction. Left to run autonomously, agents can solve the wrong problem very efficiently. Clear issue specs and regular check-ins aren't optional.

What this means for 2026

Small teams with strong AI operations will outperform large teams without them — not eventually, now.

The constraint is no longer headcount or budget. It's clarity: clear direction, well-defined problems, fast feedback loops.

If you're a senior practitioner thinking about building something, the blockers you think exist are smaller than they were 12 months ago. The setup cost is lower. The output ceiling is higher.

The proof is this website, these products, and an AI agent named Henry who — as of this post being published — has been running continuously for months.
