"At 50 hours a year, owning a share or buying a card was never going to pencil. But I had stock I was already going to sell. Putting it into a fund that diversifies it tax-deferred and gives me reliable lift on the days I need it — that's just a better version of a decision I had already made."

General Partner, Venture Capital
Partner at a Legendary VC Firm
The investor at the center of this case is a General Partner at a legendary venture capital firm. He flies roughly 50 hours a year, meaningful, but well below the threshold where a fractional share or a card pencils on aviation economics alone. He already had a charter relationship that worked. What he didn't have was a tax-efficient answer to the concentrated, low-basis stock sitting on his personal balance sheet that he had been planning to sell.
Challenge
Two unrelated decisions were sitting on his desk. The first was a concentrated equity position he had built up through carry distributions and direct investments, low basis, flagged for diversification, and queued for sale at the next reasonable window. Selling it would trigger a meaningful capital gains bill before any of the proceeds reached a diversified portfolio.
The second was aviation. At ~50 hours, charter worked. It wasn't elegant, and pricing moved with the market, but it didn't justify a fractional share's seven-figure acquisition or a jet card's deposit. He had run the math. On flight economics alone, every dedicated aviation product looked worse than what he was already doing.
The conventional alternatives reinforced the conclusion. Whole aircraft ownership failed the capital efficiency test by an order of magnitude. Fractional required a multi-million dollar acquisition that depreciates substantially over the contract, plus monthly management fees that run regardless of activity. Jet cards offered convenience at a premium to charter. None of them touched the actual financial decision he was about to make on the equity position.
Solution
The Glidepath Fund changed the frame. Rather than evaluating aviation as a standalone purchase, he contributed $1.5M of the low-basis stock he was already planning to sell directly into Craft's exchange fund a §721-structured vehicle that takes in concentrated positions 1 and diversifies the holder's exposure into a portfolio modeled to large-cap index returns2, on a tax-deferred basis. The capital gains bill he would have triggered on sale is deferred. The principal stays fully invested. And because the fund holds Challenger 350 aircraft assets alongside its diversified equity sleeve, his contribution comes with reliable aircraft access at a locked hourly rate with no monthly management fee, no peak-day surcharges, no blackout days, and ownership-level depreciation benefits.
Tax-deferred diversification of stock already marked for sale
The $1.5M contribution went in via Craft's §721 exchange mechanism, so the capital gains bill on diversifying out of the concentrated position is deferred. He achieved the diversification outcome he had already decided to pursue, without the tax friction that was holding the timing hostage.

Reliable aircraft access, included rather than purchased
At 50 hours a year, the aviation program isn't the reason to do this. But it's a real benefit. Fixed locked hourly rate for the life of the fund, contractually guaranteed access on peak days, no monthly minimums. Aviation becomes an in-kind benefit of a capital decision that already made sense on its own.
Impact
The aviation math on its own never penciled, and Craft never asked it to. The decision was a tax-deferred diversification of a position he had already committed to selling, with reliable lift attached. The capital gains bill on diversification is deferred, the $1.5M principal stays invested in a portfolio modeled to large-cap index returns rather than spent on a depreciating share, and his ~50 annual hours now run at a locked hourly rate with no spot-market exposure. The trade he had already decided to make, made better.

The Glidepath Fund accepts contributions of qualifying concentrated equity positions under IRC §721 in exchange for fund interests; tax treatment depends on individual circumstances and should be reviewed with a tax advisor.
Modeled portfolio return references S&P 500 historical annualized total return as the assumption set; not a guarantee of future performance.
Aircraft access is provided as an in-kind benefit of fund participation under terms specified in the fund's offering documents; hourly rates are locked at fund formation and are not subject to peak-day or fuel-pass-through surcharges.
