Some design work needs a fresh start. Most just needs someone who already knows your brand.
There's a point most businesses hit where one-off projects stop being the right shape. The deck for next week. The document template that's gone a bit wonky. The campaign you've been meaning to refresh. None of it big. All of it mattering.
A Mammoth retainer is what happens after that. You pay us a fixed fee. We pick up the work. By month two we know your brand. By month six we're flagging things you didn't ask us to flag.
For context: a mid-level in-house designer in Essex runs £45k+ a year, plus tools, plus management. A Mammoth retainer starts at £18k. Different shape of relationship — but the comparison is worth knowing.
