What Makes Us Different

Whole teams and single resources available

Many development houses insist clients hire a whole team even when they only need 1 or 2 resources. We have whole teams available, but we allow a la carte purchasing of resources.

No commitments required

Our team members are available to work with no minimums and no commitments. You can try our team out before you use us on a large project, or just use our services for a small scope of work.

We always assign Senior developers unless you request a junior

Other development houses will assign you junior resources without telling you. These juniors can do poor work, or fail at their tasks. Our development house is composed almost entirely of senior resources with 5+ years experience, and we will never assign you a junior unless you request one.

Resources from around the world, all with great English

We have resources from around the world, including the US. However, we don’t hire a resource unless we can easily understand each other on the phone and they can understand us. With other development houses, too often you will find that you can’t communicate with their teams due to language barriers -- we eliminate that for our English speaking clients.

Round the clock availability

We have people around the clock that are available to interact with you as needed. Our resources offer at minimum 3 hours of overlap with PST and they can adjust as needed to interact with you and your team.

Detailed accounting of hours

Our resources track time per the task they are working on, and we bill for it down to the minute, instead of in 15-minute increments like other development houses do. We watch our developers closely to ensure they are working only on the tasks that our clients assign. You can even watch our developers’ hour usage in real time, and view screenshots from their workday using our hour’s tracking system.

Tight margins

Some development houses charge 200% to 300% margins on their resources. We keep it much lower to make sure our resources are paid well enough to be fully motivated while keeping clients happy with our prices.

Easy to work with

We are stringent in our hiring requirements and only bring on people who are easy and pleasant to interact with, communicate well, and are dedicated to doing the best job possible.

Great Design/UX

Our graphic designers, product specialists, and UI/UX team are experts at creating quality design work that helps our clients’ businesses stand out.

Tempest Tools

We have a fully built, feature-rich back end based on our own rapid application development framework, ready to use out of the box. It includes a robust user management system and a whole host of other features that every back end needs, which we can easily customize for your project needs.

Local managers to sit down face to face with

We have local developers, project managers and product managers working in the Southern California area ready to assist you on site and manage a team of affordable remote personnel for you. We give you a point of contact you can sit down with, so you don't have to do it all over the phone. If you aren't in Southern California, we can work to provide you a contact in your region.
