Next steps
We only take on projects we have the capacity to deliver to exceptional standards – and we never abandon you part-way through.
Over a relaxed call or two, we’d like to hear as much as possible about your project (fully NDA’d of course).
We’ll talk about:
- Your expectations
- Your deadlines
- Your vision
If we both feel we’re a great fit for each other, we can move on to the next step.
Here we’ll estimate:
- How long the project would take.
- The shape of the team you’d need.
- How much it’s likely to cost.
Don’t worry, these estimates will be realistic. We don’t believe in sugarcoating or false promises.
If everything sounds good to you, and we have the availability to do a great job, we’re ready to get going.
