Why it matters
Supertake combines AI-generated portfolios, brokerage trade execution and social copying in one product. Its terms put users in charge of the instructions and warn that displayed returns may be simulated or unaudited, making verifiable performance and the limits of Autopilot central to whether the product earns trust.
Michael Mignano (@mignano) introduced Supertake on September 28th as a private-beta service that turns an investing thesis into a portfolio and can route trades through a user's brokerage account. In his X thread, Mignano described a user typing a view such as "humanoid robots are coming to every home" and an AI system selecting and balancing stocks to express it.

Supertake's website currently says access is invite-only and invites people to join a waitlist. The thread says the beta is free. Mignano also said users can approve trades individually or enable Autopilot, share portfolios for others to fork, compare results on a leaderboard and try ideas in Practice Mode before investing real money. The thread says the initial product supports U.S.-listed equities, with crypto, derivatives and prediction markets planned.
The brokerage details are narrower in Supertake's terms, last revised August 31st, than in the launch pitch. The thread named Robinhood and Coinbase as examples of brokerages with agents. The terms describe a Robinhood account link and say support for additional brokers may come later. They frame Supertake as software that transmits trade instructions to the broker, which handles execution, clearing and custody. The terms also say the user can authorize Autopilot within set parameters, while remaining responsible for those instructions.
That division is central to the product. Supertake is offering to turn a broad personal view into a basket and keep acting on it, while its terms say it is not a broker-dealer or investment adviser and that its AI output is not personalized financial advice. The terms warn that AI output may be inaccurate or outdated, and say user-posted performance is not verified or audited by Supertake and may include simulated Practice Mode results.
The site's public leaderboard makes that caveat material. Its displayed takes show positive returns, but the site says those returns run from each take's own record start, rather than from a common date. The terms say performance information can be simulated and is not audited. The figures therefore do not provide a like-for-like record of how the portfolios performed over the same period.
Mignano is bringing a consumer-product and founder background to a service built around making expertise and execution feel accessible. He co-founded Anchor, a podcast creation platform acquired by Spotify in 2019, and later led podcast and video businesses there. Before Anchor, he was vice president of product at Aviary, acquired by Adobe in 2014. The University of Delaware reported that he studied computer and information science there. His career has repeatedly centered on lowering the technical barriers to making something: Anchor aimed to make podcasting easier to create and distribute; Supertake applies a similar consumer-product premise to portfolio construction.
He is also a general partner at Union Square Ventures, which welcomed him to its partnership in April 2026. In the launch thread, Mignano called Supertake a USV-incubated startup and said it had cash in the bank and equity to offer founding hires, without specifying the capital amount or terms. He said he began experimenting with AI stock-research agents before deciding to build the platform.
The category already has a direct competitor with several of Supertake's visible features. Public's official product changelog says its prompt-based Generated Assets launched in November 2025; a March 2026 update added shareable pages, cloning and a leaderboard. Public keeps that product inside its own brokerage. Supertake's stated approach instead connects to users' existing brokerage accounts, though its terms currently spell out only Robinhood.
Supertake's bet is that a social layer can turn investing ideas into products people want to follow and fund, while AI handles the research and portfolio upkeep. Its public launch material does not establish how its selections are made in practice, how often they change, or how its returns compare with a common benchmark. For now, users are being asked to trust the process with their brokerage access before the company has published a comparable performance record.
