This advice depends on what you’re actually building and where you’re needing design help. If it’s a Saas product and you aren’t able to close leads due to a lack of product features, then sure, don’t hire someone to design what you already don’t have the resources to build. However, I doubt this is OP’s problem. I’m guessing they already have some traction, and are having customer complaints about the general usability or are losing to more polished competitors. In this case, it’s stupid not to bring in specialist design help. Hiring more construction workers to work on a poorly architected building won’t suddenly make it more appealing to tenants. If the architecture is the problem, hire an architect!
