who led Mariana Minerals' $310M Series B?
Mariana Minerals raised a $310M Series B led by Khosla Ventures, with continued support from a16z and Breakthrough Energy Ventures, and new participation from Greenoaks, Halo Fund, Pax Ventures, StepStone Group, BHP Ventures, Washington Harbour Partners, Greycroft, General Innovation Capital Partners, Mitsubishi Corporation, In-Q-Tel, and Earthshot Ventures.
Mariana is building a vertically-integrated minerals company: end-to-end autonomy, speed to market, and lower costs for critical minerals, the inputs every major industry is now short of.
who led Valar Atomics' $1B Series B?
Valar Atomics raised a $1B Series B led by Sequoia, with Valor Equity Partners, Atreides, Point72, and Conviction, alongside a $200M credit facility led by Erebor and J.P. Morgan. Shaun Maguire of Sequoia joins the board.
Valar is building the largest nuclear sites in the world for industrial electricity, heat, and carbon-neutral synthetic fuels.
who's in OLIX's $312M Series B?
OLIX raised a $312M Series B at a $3.3B valuation, more than tripling its value in six months. the round saw participation from Arm, Fundomo, Hudson River Trading, Netflix co-founder Reed Hastings, and the UK government's Sovereign AI venture fund, with existing investors Plural, Hummingbird Ventures, Phoenix Court, Crane, Creandum, and Transition expanding their commitments.
the UK-based company builds the infrastructure for frontier AI: specialised silicon connected by an optical network, unrolling models across racks like an assembly line instead of forcing a single chip to do everything. founder: James Dacombe.
who led The Intelligence Company's $7.9M seed?
The Intelligence Company raised a $7.9M seed led by Index Ventures, with Conviction, A*, and Y Combinator.
the team of 10 behind DesignArena scaled from $5M to $60M ARR in 6 months, with 5.5M users across 190+ countries: models compete to fulfill real requests, and live user behavior is the benchmark.
how early did frontrun flag them?
Mariana Minerals: flagged april 21, announced august 3. 104 days.
Valar Atomics: flagged february 16, announced august 3. 168 days.
OLIX: flagged may 4, announced august 3. 91 days.
The Intelligence Company: flagged february 16, announced august 3. 168 days.
the february flag landed on DesignArena, the product account, months before the parent company account existed. same company, same follow graph, receipt intact.
the graph moved before the news, all four times
this is the part worth reading twice.
Valar: between the flag and the round, 12 tracked investors followed the company. Sarah Guo followed july 9; Conviction is in the round announced today. Shaun Maguire followed july 31, three days before he was announced on Valar's board.
Mariana: two a16z partners followed in the final four days: one on july 30, and one the morning of the announcement. a16z is in the round.
OLIX: flagged may 4 via Frictionless Capital's founder. then a Multicoin Capital partner followed june 26, and Cantos Ventures' founder followed july 29, five days before the announcement.
The Intelligence Company: between the february flag and the round, the graph filled in with a Paradigm researcher, a YC general partner (Gustaf Alströmer, july 5; YC is in the round), Andrew Ng, an a16z GP, and finally Sofia Dolfe of Index Ventures, the day before Index led the round.
none of that is inside information. it's public follow data, watched account by account, stamped the morning it happens. investors follow companies before they talk about them; the round is visible in the graph while the press release is still a draft.
a $1.63B day for the receipt ledger
our receipt ledger has a 7-day minimum lead: a flag has to beat the round by at least a week to count as a discovery rather than a leak of imminent news. at 91 to 168 days, all four of today's rounds clear the bar with months to spare, and all four enter the ledger with sources.
see the list before the round
these four already raised. the useful list is the one where the round hasn't happened yet.
frontrun watches the follow graphs of 1,000+ tracked venture investors on X and flags the companies they converge on, with a date, the morning it happens.
every round we flagged before it was announced, with sources: /fundraises. last month: july 2026.
