tl;dr: three outcomes landed on august 13 2026, and the follow graph called every one before the news. Uplift announced a $7M seed led by a16z: flagged 32 days earlier at 15 followers, with an a16z GP following 35 days before the announcement. Lemma announced a $2.3M pre-seed backed by Matrix and YC: flagged 65 days earlier at 107 followers. and Turf was acquired by Polymarket: flagged 199 days before the deal. (Castle also launched today, flagged 85 days early through its founder: that receipt gets its own post.)
who led Uplift's $7M seed?
Uplift raised a $7M seed led by a16z. the founders built at SpaceX and Tesla, and they're applying the same playbook to housing: homes built the way cars are built, on a production line, with cost falling on every version. first homes deploy in the next 3 months.
We are launching Uplift, backed by a $7M seed led by a16z. We build homes the way cars are built: on a production line.

flagged july 12 at 15 followers, announced august 13. 32 days.
the flag wasn't the first move the graph made. an a16z general partner followed the account on july 9, 35 days before his fund announced it led the round. by announcement day, 7 tracked investors were on it.

who backed Lemma's $2.3M pre-seed?
Lemma raised a $2.3M pre-seed backed by Matrix, Y Combinator, and Liquid 2 Ventures, with angels from OpenAI, xAI, Meta, and DoorDash.
lemma is production monitoring for AI agents. monitoring tools only catch what you told them to watch for; agents fail in ways you didn't predict. lemma learns what your agent is supposed to do and surfaces failures you never defined, automatically. the platform has already processed over a million agent traces.
Agents are taking on real economic work. As runs get longer, mistakes become expensive at best, catastrophic at worst. That's why we built @uselemma_ai.

a flag is a flag, whatever the exit
our receipt ledger tracks rounds: flag date vs announcement date, minimum 7-day lead. but the same signal front-runs every kind of outcome. today it was a seed round, a pre-seed, and an acquisition, from the same graph: tracked investors hitting follow weeks or months before anything was public.
see the list before the news
these three already happened. the useful list is the one where nothing has been announced yet.
frontrun watches the follow graphs of 2,000+ tracked venture investors on X and flags the companies they converge on, with a date, the morning it happens.

companies and founders surfaced on frontrun. curated, every week.
