IPO. Lantern Capital Advisors, as an hourly based corporate financial planning firm and corporate financial consultant, is an alternative to investment banking. Just like an investment banker, we help our clients comprehend the mandatory steps required to go public. We help clients identify, interview and select numerous quality underwriters. Once our clients select their underwriters, we assist our clients during the due diligence phase, and monitor the company’s progress to ensure our clients realize their initial objectives post IPO.
