GLASSCOCK, Vice Chancellor This post-trial opinion addresses the ownership interest held by Plaintiff, Ari

Rostowsky, in a business he formed with Individual Defendants, Laura Hirsch and

Lisa True. The business is formally structured as a Delaware LLC, Aither Health.

It is a service business related to administration of health insurance claims. Plaintiff

avers that he is a member of the LLC. However, there is a written LLC operating

agreement that states that there are only two members of the LLC, Hirsch and True.

Plaintiff advances another claim, however; that he is entitled to a share of the

business under the rubric of promissory estoppel. The record at trial demonstrates

that Plaintiff is entitled to a 15% share of the business (or damages) under that

theory, based on the following facts. The parties, including Plaintiff, created the

company. The parties also made clear in their business plan that Plaintiff was a

“Founder” of the company. They did not disclose to him that they had executed an

LLC operating agreement that excluded him, and Plaintiff expected and attempted

to facilitate an LLC operating agreement that would acknowledge his interest.

Defendants relied on these assertions and omissions to benefit themselves and the

LLC at Plaintiff’s expense, most notably by 1) causing Plaintiff to work for more

than a year without pay based on his understanding that the waxing value of his

equity would eventually compensate him, and 2) relying on Plaintiff to secure a start-

up loan to the business from a company in which his father was a principal. The

million-dollar loan was made without collateral, was not convertible to equity, and

1 was guaranteed only personally by Defendants. This loan was based on a business

plan that referred to Hirsh, True, and Plaintiff as “the Founders,” and Plaintiff’s

father testified that he would not have approved the loan absent the parties holding

Plaintiff out as a co-owner.

Finally, in an email to Plaintiff by True, copied to Hirsch, True stated that

Plaintiff owned 15% of Aither’s business. Hirsch did not dissent. I find by clear

and convincing evidence that Hirsch and True are estopped from asserting that

Plaintiff is not a 15% owner of Aither’s business, although not a member of the LLC

under the LLC operating agreement.

Plaintiff eventually left his work for Aither. Subsequently, the parties

disagreed about Plaintiff’s stake in Aither, which Plaintiff argued should be 1/3, and

which Defendants insisted was inchoate and unvested. 1

This Memorandum Opinion leaves other matters unresolved, including how

equity should vindicate Plaintiff’s rights. I address here only the issue described

above.

1 Defendants argue, without the support of written evidence, that Plaintiff agreed to five year’s labor as a condition precedent for receiving a share of Aither, a term of service he failed to complete. One wonders whether, upon completion of the term, like Jacob (Genesis 29:20–35), Plaintiff would have received less attractive equity.

3 Non-party Richard Rostowsky (“Richard”) is Ari’s father and a former owner

of a TPA named S&S Healthcare. 9

2. The Parties Prior Involvement with TPAs

Prior to joining Aither, Plaintiff worked in sales for his father’s TPA, S&S

Healthcare, from September 2011 to April 2019. 10 Hirsch and True met Plaintiff at

their place of employment, Nova Healthcare, another TPA company. 11 S&S

Healthcare provided services to Nova Healthcare. 12 In August 2018, Richard and

his business partner sold S&S Healthcare to a private equity company.13 At the time

of the sale, Plaintiff signed an employee agreement that contained a non-compete

and non-solicitation clause.14 After the sale, S&S Healthcare terminated Plaintiff’s

employment in April 2019. 15

In April 2019, Plaintiff, Hirsch, and True began discussions about going into

business together by purchasing Significa Benefits, an existing TPA. 16 Hirsch and

True learned of Significa Benefits through Plaintiff. 17 Plaintiff introduced Significa

Benefits personnel to Hirsch and True, and the pair expressed an interested in buying

Rostowsky) 81:8–82:8. 12 Tr. (True) 190:8–191:13; Tr. (A. Rostowsky) 81:19–82:8; PTO ¶ 5. 13 PTO ¶ 3. 14 Tr. (A. Rostowsky) 8:17–9:9; JX68. 15 PTO ¶ 4. 16 Tr. (A. Rostowsky) 14:11–15:18; Tr.

4 the company.18 After two meetings with Significa Benefits, Hirsch and True

prepared a business plan which outlined the following ownership structure: Hirsch

and True would each own 30%, Plaintiff would own 15%, and two other individuals

would own 20% and 5%.19 Plaintiff did not agree to the ownership breakdown.20

Ultimately, and in any event, Plaintiff, Hirsch, and True decided that purchasing

Significa Benefits was not an ideal business decision and settled on forming their

own TPA.21

3. The Formation of Aither Health LLC

In summer 2019, the parties took steps toward forming Aither. On July 2,

2019, Hirsch and True executed a certificate of formation,22 initial resolutions,23 and

an operating agreement for Aither. 24 The operating agreement listed and currently
