Our Stack
The tools we reach for every day
Boring, proven, scalable. We pick the same stack the largest internet companies use — because it stays maintainable as you grow.
How We Work
A clear path from zero to internet scale
No black boxes. You see progress every week and can steer the direction as we go — from MVP to 100M users.
01
Discover
We map your users, growth model, and the metrics that matter. The output is a written product & architecture plan, not slides.
02
Prototype
We ship a clickable product prototype and a deployable backend skeleton in the first two weeks, so we can both react before we build.
03
Build & Ship
Short agile sprints with continuous deploy. Code is tested, observed, and rolled out behind feature flags from day one.
04
Operate
24/7 on-call, SLOs, dashboards, and capacity planning. We stay on as long as you want us — from launch day forward.

Product teams that scaled with us
What it’s like to have Acorn Creek in your corner when traffic is spiking.
Our consumer app went from launch to 18 million daily users in 14 months. Acorn Creek was the team that made sure the platform never once buckled under that growth.

Jessica LinVP Product, NovaPay
They don’t just write code — they ask why. Every demo included honest advice on what to cut, what to ship, and what would actually move retention.
M
Marcus WebbCTO, Gridform
We hit a twelve-times traffic peak on our biggest sale day, with zero downtime and a 38% lower infra bill. That is the kind of operator you want on your side.

Why Acorn Creek
Engineered to be your long-term platform partner
We’re measured by your growth — not by the hours we bill.
Outcome-Driven
We focus on measurable product outcomes — retention, latency, GMV — not just tickets closed. Every engagement starts with the metrics that matter to your business.
Ship & Learn
Continuous deployment, feature flags, and weekly demos keep you in the loop. You can steer the product every Friday, not just at the kickoff.
Built for the Long Run
From MVP to IPO scale, we keep the system maintainable: typed code, tests, runbooks, on-call rotations — the unglamorous stuff that wins in the long run.
FAQ
Common questions
What product teams usually ask before we talk.
Anywhere from pre-launch to hundreds of millions of users. About a third of our work is helping founders take a product from zero to first traction, another third is taking a growing product through its first big scaling moment, and the rest is operating mature platforms. The work looks different at each stage but the principles don’t.
Three models: fixed-scope for well-defined builds, a dedicated squad of 3–6 engineers rolling monthly for evolving products, and a 24/7 platform operations retainer for mature systems. You get a written estimate before any work begins, and we share the cost model in plain English.
Yes — most of our platform work is modernizing or extending systems other teams built. We start with a two-week technical audit, then propose incremental improvements (observability, performance, reliability) rather than risky rewrites. You keep shipping while we tighten things underneath.
Every product we run has a written SLO, an on-call rotation, dashboards, and a runbook. When something breaks, your team and ours are paged together and we run a blameless post-mortem within 48 hours. We treat reliability as a product feature, not an afterthought.
