How much you need to move the needle, how quickly, and how many team members we'll need to achieve your goal determines our rates. Which is why, before we propose anything, we usually want to look at your metrics together and come up with some numerical goals for the engagement.
To give you a range, our holistic retainers, which often mix some combination of UX research, Analytics, A/B testing and CRO, PPC, SEO, Design, and Development typically run between $20,000-$60,000 per month.
That said, we have taken some startup clients on for $12,000 - $15,000 per month, plus warrants, and we have also had some larger $80,000-$100,000 per month engagements. Get in touch and we'll figure it out together.
