IonSeq Genome Sequencing Abstract The emergence of advanced DNA sequencing methods has presented disruptive opportunities in biotechnology, establishing the foundation for the personalized medicine industry. Since the completion of the Human Genome Project, the number of genomes sequenced has grown exponentially and the sequencing price has dropped precipitously. To make personalized medicine a reality, there is a need for a large collection of sequenced genomes in order to link specific genes ot diseases. IonSeq seeks to be the leading DNA sequencing service, employing new semiconductor- based sequencing technology offered by Ion Torrent, to help pharmaceutical companies generate these libraries of genomes for their drug- development processes. To support sequencing reliability and throughput, IonSeq will explore such technical details such as chip configuration, insertion kinetics, signal generation, base-calling methods, and accuracy metrics. IonSeq will prove a 40 genome/day output, made possible by the massively parallel procedure employed by the sequencers. IonSeq will sequence each genome at a price of $2,000 while the cost of ‘manufacture’ will only be $645. Series A will consist of a $3,682,886 investment and will yield the investors a MIRR of 102.98% over four years. The Series B investment will total $4,510,491 and result in a 93.43% MIRR over a three period. The NPV by the time of liquidation or acquisition event will be $39,322,347, at a conservative projected growth rate of 5%.

The enclosed report documents our entire design process and decisions that were made during the formulation of this process. The report also contains a competitive analysis, market analysis, and financial models of the start-up company. This report contains all necessary information for hypothetical start-up scientists and engineers, whom could, with the use of this report, design a working prototype for IonSeq as per this project’s specifications. This report also provides all necessary information that a potential investor in IonSeq would require in order to make an investment decision for the company’s future. We submit this report for your review with our strongest recommendations of the success of IonSeq.
