Fast to build.
Built to last.

Fastness is a small software studio. We build web apps, ecommerce, mobile apps, and AI features for local businesses and remote tech teams — at a fixed price, with code you own.

What we build

Real software for real businesses.

Senior engineering on proven tools, pointed at whatever your business actually needs next.

Web apps & SaaS

Customer portals, admin tools, and full products, from first commit to production. Django, React, and Postgres: proven tools, no exotic bets.

Ecommerce

Storefronts and custom checkout flows, plus the inventory, fulfillment, and integration work happening behind them.

Mobile apps

Apps for customers and field staff, sharing a backend with your web product so nothing gets built twice.

Logistics & routing

Route optimization, dispatch, and scheduling. We've built it at scale and we run it as our own product.

AI features

Practical AI inside your product (search, summarization, classification, automation) where it earns its keep, and nowhere else.

Rescue & tune-ups

Inherited a shaky codebase? Security reviews, test suites, and performance work, with a plan to get it steady.

Built with you in the loop, and handed over with full ownership.

Who we work with

Two kinds of clients. One way of working.

Local businesses

You run a shop, a service company, a clinic, a fleet. You need software that fits how you work, and someone across the table who explains it in plain English. We're in New Jersey and glad to meet in person around the NYC area.

Remote tech teams

You have a roadmap and not enough hands, or a feature outside your team's wheelhouse. We take on a defined project, work in your repo and your tools, and leave it tested and documented.

How we work

No mystery. No surprises.

  1. 01 Scope and price are agreed before we start.
  2. 02 Small steps, shipped often. You see working software every week.
  3. 03 Boring, well-supported tools, so anyone can maintain what we build.
  4. 04 Your code, your data, your accounts. From day one.
Fixed scope. Fixed price. Software that stays up.

Pricing

Straightforward pricing.

Every project is scoped up front and quoted at a fixed price. Most land somewhere in these ranges.

FAQ

Questions we hear a lot.

How long does a build take? +

Most projects run four to twelve weeks. We agree on scope and a schedule up front, then you see working software every week instead of one big reveal at the end.

Do I actually own the software? +

Yes. The code, the data, and the hosting accounts are yours from day one. Whenever we can, we work in your own repository.

How much does it cost? +

Fixed-price projects generally run $10k to $50k depending on scope. We quote after a short call, so there are no hourly surprises.

What if it doesn't work out? +

We build in small, shippable steps, so you can stop at any milestone and keep everything built so far. And if we're not the right fit, we'll say so on the first call.

What do you build with? +

Mostly Python and Django, React, and Postgres, deployed on AWS or wherever you already are. If you have a stack, we'll happily use it.

Why “Fastness”? +

It's an old word for a stronghold, and it has “fast” in it. We wanted both from a software studio.
