Async Labs: We build custom SaaS web applications.

Building a SaaS web application is still hard. Modern web tooling lets you build delightful user experiences. The downside is that you have to stay up to date with this ever-growing and ever-changing tooling (frameworks, libraries, concepts, ideas). If you appreciate readable, maintainable and extendable code, consider working with us.

With new clients looking for a long-term engagement, we like to start with a trial project (1-3 weeks). If we're both happy, we'll continue the engagement and bill per week based on the number of hours we work that week.

Currently, we are very interested in supply chain, logistics, and inventory management projects. If you are building or planning to build a project in any of these areas, tell us more.

We charge $120/hour. Our max capacity is 80 hours/week from 3 engineers. Our current capacity is 20 hours/week.


About you

You can be at any stage of development: no sketches and no codebase, codebase that needs a full refactor, codebase that needs a new feature, etc. You can be an individual, startup, or small business.

You can be building a new SaaS product or an internal tool to make your existing business more efficient. We prefer to work with clients who have some technical background. You don't have to code every day, but understanding project structure and web architecture will be very helpful.

We give preference to codebases with React.js on frontend and Node.js on backend. We write both frontend and backend with TypeScript. If you bought our SaaS Boilerplate book to build your web application, we will assign a higher preference to work with you.


About us

We are a small team: Timur (Lead Engineer), Kelly (UX, UI), and two part-time contractors. Our experience includes:



SaaS web app development
  • We've built over a dozen SaaS web applications in the last 5 years for our clients and for ourselves. See example projects below.
  • In addition to our technical expertise, we learned complementary skills from participating in Techstars accelerator in 2016. Our paywall software startup was funded by Techstars and other investors.
  • We interact with customers on a weekly basis (books, custom development). We understand your challenges intimately.
Open source repos
  • We maintain two popular open source repos: saas and builderbook.
  • Our repos have >1000 unique visitors per week. Over 100 people sign up on our SaaS Boilerplate demo every week.
  • Our SaaS Boilerplate is the most popular open source React/Next.js/Node.js boilerplate. And it's written with productive TypeScript on both front-end and back-end.
  • We also open-sourced our internal team communication tool, Async, which separates urgent vs. non-urgent conversations.
Software books
  • We wrote and self-published two books at builderbook.org.
  • Over three years, we've sold 1000+ copies with less than 3% refund rate.
