About Us

Tower59 was founded on the belief that professional services are over-priced and inefficiently positioned for the growing companies they serve. As entrepreneurs ourselves, we understand that the needs of early- and mid-stage companies differ greatly from those of larger, more established companies.
Since the inception of the IRC 409A regulations in 2005, a lack of competition has allowed a cottage industry to overcharge entrepreneurs for an independent valuation of their company’s shares. We launched Simple409A to better serve the niche customer that is a growing company. Through a mix of automation, workflow optimization, a distributed US-based workforce, and volume, we are able to significantly reduce the cost of a 409A valuation.
