sep 22: @atumhq out of stealth. $13.5M. 🫡
Atum is building an open payments network for global money movement. the company raised $13.5M from Variant, PayPal Ventures, Abstract, and others, announcing the round alongside its exit from stealth.
flagged september 21 2026, announced september 22 2026. 1 day.
atum had 8 followers when frontrun flagged it. 15 tracked investors were already following the account. the signal was quiet but the graph was not.
the fuller story goes back further. a tracked account was flagged 42 days before the announcement, in stealth, before atum even had a public presence. by the time the raise went public, the pattern was clear to anyone watching the graph.

Midcentury: $15M series seed, flagged 197 days early

FUNDRAISE 💰: @frontrunvc flagged @MidcenturyAI, on March 9th.
197 days later: out of stealth with a $15M series seed. 🫡
Midcentury builds data and simulation infrastructure for embodied AI. the company was in stealth until today, when it announced a $15M series seed.
flagged march 9 2026, announced september 22 2026. 197 days.
11 tracked accounts were following before the announcement. that kind of early, quiet attention across a graph of 2,000+ tracked accounts is exactly what frontrun is built to catch.
embodied AI needs infrastructure. the simulation and data layer is where the hard work happens, and the graph had it months before the press release.

Baselayer raises a $35M Series A, 122 days after we had them
Baselayer verifies businesses for banks, fintechs and payments companies: KYB, credit and fraud risk. today it announced a $35M Series A led by M13, taking it to $40M raised since 2023.
we had Baselayer on may 23 2026, announced september 22 2026. 122 days.
the company account is not where the signal was. on may 23 a tracked account followed co-founder and CEO Jonathan Awad, whose bio named the company. the company's own X account did not pick up a tracked follower until september 14, eight days before the round.
that is the point of watching founders as well as companies. the person is public long before the company is.

see the list before the round
these already happened. the useful list is the one where the round or the launch has not happened 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.
