Fizz, the college-focused anonymous social app, filed an expanded claim in its ongoing lawsuit against rival Sidechat on July 10, alleging that Maveron venture capitalist Jerry Lu met with Fizz founders under the guise of exploring a potential investment, then turned around and shared the company's confidential fundraising materials directly with Sidechat, according to TechCrunch reporting.
The filing gets specific: Fizz alleges Jack Burlinson, described as an acquaintance of both the founders and Lu, passed along confidential materials -- including Fizz's investor deck and a fall summary document prepared specifically for prospective investors -- to Lu, who then shared those materials with Sidechat. If accurate, the allegation describes exactly the kind of investor-access abuse that founders fear most during fundraising: using diligence access as a pretext to gather competitive intelligence rather than genuine investment interest.
Sidechat CEO Kyle Venn, who also runs the related anonymous-social platform Yik Yak, pushed back directly, telling TechCrunch the claims are "allegations, not court findings" and that Sidechat denies any wrongdoing and will address the matter through the legal process. Requests for comment sent to Lu and Maveron were not returned, leaving the VC's side of the story unaddressed publicly for now.
“Requests for comment sent to Lu and Maveron were not returned, leaving the VC's side of the story unaddressed publicly for now.”
The filing extends a lawsuit Fizz originally brought against Sidechat in 2023, alleging a broader pattern of anticompetitive conduct including disrupting Fizz's campus launches, spreading false rumors about hackers accessing Fizz's data, filing false spam reports against Fizz with Instagram, and paying students to delete the Fizz app -- meaning this VC-leak allegation is the latest chapter in an already contentious rivalry rather than an isolated incident.
For founders raising venture capital, the case is a sharp reminder to be deliberate about which competitive-adjacent investors get access to sensitive fundraising materials, and to consider NDAs or more limited information-sharing with investors whose portfolios or relationships create plausible conflicts of interest. For LPs and the broader venture community, an allegation this specific against a named investor at a recognizable firm -- if it holds up -- would be a genuinely rare instance of a confidentiality-breach claim advancing far enough to become public court filings rather than staying an industry whisper.
The bear case: allegations in a legal filing aren't proven facts, and Maveron and Lu haven't yet had the opportunity to respond substantively in court; the claim could also be difficult to prove without clear documentary evidence of the alleged information transfer. What to watch next: whether Maveron or Lu file a formal response or motion to dismiss, and whether the underlying Fizz-Sidechat litigation from 2023 finally reaches a resolution now that it's absorbed this new allegation.
