Three founders of StraightPath Venture Partners LLC received lengthy federal prison sentences for defrauding investors through a private pre-IPO investment scheme that involved hidden markups, undisclosed fees, and misleading claims about access to non-public company shares.

According to the U.S. Attorney’s Office for the Southern District of New York, Michael Castillero, also known as Michael Alejandro, was sentenced to 11 years in prison; Brian Martinsen was sentenced to 10 years in prison; and Francine Lanaia was sentenced to 8 years in prison. The court also ordered $115 million in restitution and significant forfeiture amounts against each defendant. (www.justice.gov/usao-sdny/pr/pre-ipo-fraudsters-sentenced-8-10-and-11-years-prison)

The StraightPath case highlights the risks investors face in private offerings, pre-IPO funds, and alternative investments, especially regarding valuation transparency, fee disclosure, asset custody, and sales practices.

The StraightPath Pre-IPO Investment Scheme

From 2017 to April 2022, prosecutors said Castillero, Lanaia, and Martinsen operated nine related private funds called the “StraightPath Funds.” Investors were told they would gain access to privately held companies before their initial public offerings.

The U.S. Attorney’s Office said the defendants used “boiler room”-style call centers to market the investments, including to individual investors, and represented that investors could acquire interests in pre-IPO companies at favorable prices before those companies went public.

Prosecutors said the defendants bought pre-IPO shares and resold them to investors at inflated, undisclosed markups. They also allegedly misled investors about the investments and concealed the involvement of Castillero and Lanaia, who had been barred from the securities industry by FINRA.

Nearly $400 Million Raised From Investors

According to the DOJ, the StraightPath defendants raised nearly $400 million from investors. Prosecutors said each defendant took about $25 million, and together with associates, misappropriated roughly $130 million in investor funds. The DOJ further stated that investor money was spent on luxury goods, houses, cars, watches, and a boat.

The Securities and Exchange Commission had previously filed a parallel civil action involving StraightPath Venture Partners, StraightPath Management LLC, Brian Martinsen, Michael Castillero, Francine Lanaia, and Eric Lachow. According to the SEC, the defendants conducted a fraudulent $410 million offering, allegedly sold pre-IPO shares they did not own, pocketed undisclosed fees, commingled investor funds, and made Ponzi-like payments.

Why Hidden Markups Matter in Pre-IPO Investments

Pre-IPO investments are challenging for most investors to evaluate because private company shares do not trade on public exchanges. This lack of transparency can make it difficult to determine if the price is fair.

In the StraightPath case, prosecutors said investors were told there were no upfront fees, while defendants allegedly resold shares at undisclosed, inflated prices. Such markups can significantly reduce an investor’s economic position from the start.

For example, if an investor believes all funds are used to acquire pre-IPO shares, but a significant portion is taken through undisclosed markups or commissions, the investor begins at a disadvantage before the investment can perform.

SEC Also Charged StraightPath Sales Agents

The StraightPath case also raises concerns about the role of sales agents and unregistered brokers in private investment offerings.

In 2023, the SEC charged three sales agents — Scott Hollender, Gabriel Migliano Jr., and Frank Vecchio — with selling interests in pre-IPO shares on behalf of StraightPath Venture Partners despite allegedly not being registered broker-dealers. The SEC alleged that the sales agents solicited at least $13 million from at least 115 investors and received approximately 10% upfront commissions, while allegedly telling investors there were no upfront fees. (www.sec.gov/newsroom/press-releases/2023-61)

This issue is important for investors because transaction-based compensation often indicates broker activity. When individuals solicit investments, recommend securities, receive commissions, or serve as the main contact for investors, registration and supervision become critical factors in assessing potential misconduct.

StraightPath Receivership and Investor Distributions

The StraightPath entities and funds are no longer operational and are under the control of a court-appointed receiver. The receivership website states that the criminal defendants were found guilty in November 2025 and sentenced on May 20, 2026. The receiver has also provided updates regarding investor distributions, including a planned June 2026 distribution expected to exceed $3.1 million for eligible investors who submitted proper tax forms.

While receiverships can help preserve and distribute remaining assets, they often do not fully compensate investors. In many fraud cases, investors should consider whether additional recovery options exist beyond the issuer or fund, including claims involving sales agents, brokers, advisors, referral sources, custodians, or others involved in the investment process.

Lessons for Investors in Private Offerings and Alternative Investments

The StraightPath case underscores several warning signs investors should consider when evaluating pre-IPO investments, private placements, and alternative investments.

  • Question “Special Access”: Investors should be cautious if told a private investment offers special access to shares in well-known companies before an IPO.

  • Verify Costs & Licenses: They should ask how the investment is priced, who is compensated, whether commissions or markups are included, and if the sellers are properly licensed.

  • Trace the Capital: Investors should also determine whether their funds are used to purchase a specific asset or if funds may be pooled, commingled, or used for purposes not described in the offering materials.

In private markets, undisclosed information can be as important as disclosed details. Hidden fees, undisclosed conflicts, inflated valuations, and unregistered sales activity can all undermine an investment’s integrity.

Legal Options for Investors

Investors who suffered losses in StraightPath-related investments, pre-IPO funds, private placements, or similar alternatives may have legal options. These depend on how the investment was sold, who recommended it, what disclosures were made, and whether any broker, advisor, or sales agent violated their duties.

Potential claims may include misrepresentation, omission of material facts, unsuitable recommendations, failure to disclose conflicts of interest, unregistered broker activity, breach of fiduciary duty, negligence, or supervisory failures.
