Selling to new Cambridge companies
A company in its first months is still choosing who it works with. Reaching it then, with a short email that names what it has just started, is often the easiest time to win them as a client.
- Marketing agenciesA new company needs a website, a logo and its first customers, usually before it has picked anyone to help.
- AccountantsEvery new company owes a first set of accounts and a confirmation statement, and many have no accountant yet.
- IT and software firmsEmail, devices and security get set up in the first months, and the choices made then tend to stick.
- Insurance brokersEmployers' liability, professional indemnity and van cover are bought early, often in a hurry.
- RecruitersThe first hires come quickly once a new company wins work.
