The Fractional Restructure
The Fractional Restructure
"I could afford to keep doing it. That's exactly why I stopped. When the bill feels wasteful, it is wasteful."

Seth Berman
Partner at a Legendary VC Firm
Seth Berman is a General Partner at Susa Ventures, whose first investment was notably a seed round in Robinhood that delivered a 1,000x+ return. He had been a fractional program customer for several years, flying roughly 100 hours annually. The product was excellent. The economics were not.
Challenge
At his utilization level, Seth's all-in fractional program cost exceeded seven figures annually. The monthly management fee, charged every month whether or not a single flight departed, accounted for nearly half of his annual fixed aviation spend. The other half was tied up in an acquisition that, at contract end, returns roughly 50 cents on the dollar. The provider controls the resale timeline and pricing. The exit is neither fast nor favorable.
When Seth received liquidity from exits in his fund, his advisor asked a pointed question: before we deploy new capital, what are we currently doing with capital we wouldn't do again knowingly? The aviation program surfaced immediately. He realized he wouldn't accept these terms for any other asset class he held. The monthly statement had simply never been examined with the same rigor.
Solution
Seth exited his fractional program and invested in the Glidepath Fund, an exchange fund using Craft's tax-deferred investment mechanism. Rather than selling appreciated stock positions and triggering a capital gains event, he contributed the positions directly into the fund. The gain was deferred. Aviation access transferred to Craft's locked hourly rate with no flight minimum or monthly fees.
Monthly fixed fee eliminated entirely
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.
Same aircraft, fundamentally different economics
A parallel evaluation confirmed the product match: Challenger 350 cabin, ARGUS Platinum safety rating, Starlink on every aircraft. No material difference in the flying experience. The capital structure behind it changed completely.
Tax-deferred entry via Craft's exchange-fund mechanism
Appreciated stock contributed directly into the Glidepath Fund defers the capital gains liability that would otherwise be recognized at point of sale. The full principal remains invested. The tax clock pauses until the investor exits the fund.
Impact
Seth's five-year all-in aviation cost is more than 50% lower than continuing with fractional ownership without even factoring in the tax-deferral benefit. The result is driven by eliminated fixed fees, capital preserved in a growing fund rather than a depreciating asset, and the tax deferral achieved on entry. The monthly billing transformed from a recurring frustration into a single, predictable variable: hours flown at a locked rate.
Portfolio Impact
Metric | Prior Portfolio | With Craft |
|---|---|---|
Capital locked in aviation asset | ~$3.6M, declining ~10%/yr | $3M, modeled growth, fully invested |
Annual fixed fees | ~$500k, regardless of use1 | ~$45K (1.5% AUM only) |
Concentrated stock position | ~$630K at published rates | ~$695K at locked rate |
Capital recovery at exit (modeled) | ~50% of original commitment | ~140% of original commitment2 |
Net annual portfolio drag | ~41% on committed capital | ~18% net cost, capital intact |
Annual fixed fees figure based on the Goldman Sachs fractional ownership proposal (April 2025) for a comparable Challenger 350 share at this utilization level.
Capital recovery at exit assumes ~7% annualized fund growth net of fees over a five-year horizon vs. published fractional residual values; modeled scenario, not a guarantee.
