She runs her own web/digital marketing company and is the only full-time employee (which includes time for school pick-up/drop-off). She has a few freelancers for graphic design and content writing and I help out as I can while working a full-time corporate job.
Her company revenue is over 300k/year.
For a long time new clients were mostly Google Ads/Remarketing, word-of-mouth and customer referrals and a few ongoing relationships with sales executives in traditional media like TV, radio, etc. Over time organic SEO has come into it as her ranking improved.
There's been minimal networking which is always a concern if online stops working. There's just not the time to be out at business chambers, BNIs, etc, look after kids and get work done. It's also a long term commitment.
