William & Henry Associates

What William & Henry Associates does

William & Henry Associates is a privately held boutique investment banking firm founded in 2001 by David J. Iannini and headquartered in Los Angeles, California. The firm exclusively serves lower and middle-market private companies — typically those executing transactions in the $25 million to $200 million range — providing M&A advisory, capital raising, leveraged transaction (management buyouts, recapitalizations, take-privates), and financial advisory services such as fairness opinions, securities valuation, capital structure optimization, and exit preparation. The firm has additional offices in Long Beach, California and Scottsdale, Arizona, and is registered as a broker-dealer with FINRA/SIPC, with securities products offered through a relationship with Innovation Capital, LLC.

The firm's value proposition is anchored on a single-client representation model: it deliberately does not represent private equity firms, public companies, or other "opposite side" parties, eliminating conflicts of interest and allowing aggressive negotiation on behalf of the private business owner. Services are delivered through a small senior team of Managing Directors and senior professionals averaging over 15 years of experience, with backgrounds at bulge bracket (Salomon Brothers, Schroder Wertheim) and major bracket (Barrington Associates) firms. Iannini personally has executed over 200 transactions and raised over $5 billion in capital across a 30-plus year career.

The business model is purely advisory and fee-based, with compensation derived from transaction success fees on closed deals and advisory retainers. The go-to-market approach is sales-led and referral-driven, leveraging senior professional networks, accounting and legal referral partners, and earned media recognition (including ten consecutive years on the Los Angeles Business Journal Top Investment Banks list and LA Times Investment Banking Visionary honors for the CEO in 2021 and 2022). The firm operates without a proprietary technology platform — value is delivered through human expertise, process discipline, and curated buyer networks rather than software or automation.
