Atomic

IMPORTANT DISAMBIGUATION: There are multiple, unrelated companies named "Atomic" relevant to Greylock's world. (1) Atomic AI (atomic.ai) is an RNA-biology/drug-discovery company, profile_id 10043618, researched separately -- NOT this company. (2) "Atomic" is also the name of a well-known startup studio co-founded by Jack Abraham (with backing/association from Alexis Ohanian and others) that incubates companies like Hims & Hers and Homebound -- NOT this company either. (3) There is also a distinct, separate fintech company that also brands itself simply as "Atomic" and is an embedded-investing/brokerage-as-a-service platform led by CEO David Dindi; it raised a $30M growth round in August 2025 led by Aquiline and Brewer Lane with participation from Intuit, Nationwide Ventures, Erie Strategic Ventures, Samsung Next, Appia Ventures, QED Investors, Anthemis and Y Combinator, and counts NerdWallet, Yieldstreet and Bluevine as customers (per Crowdfund Insider, Aug 2025). That company appears to be UNRELATED to Greylock (no Greylock investor was named in its funding coverage) and is a DIFFERENT entity from the one profiled here, despite both using the single word "Atomic" as a brand and both operating in consumer fintech infrastructure. This profile (profile_id 10072967) is specifically and exclusively about the company at the domain atomic.financial, founded by Jordan Wright, Scott Weinert and Andrea Martone, whose legal entity name is "Atomic FI, Inc." This identity was independently cross-verified via: (a) Atomic's own website and About page at atomic.financial, which lists Jordan Wright, Scott Weinert and Andrea Martone as founders; (b) Greylock's own portfolio page at greylock.com/portfolio/atomic/, which names the same two leaders (Jordan Wright as Co-Founder & CEO, Scott Weinert as Co-Founder & CTO), lists HQ as Salt Lake City, UT, and describes the business as 'payroll connectivity and infrastructure'; and (c) TechCrunch's Oct 2021 and March 2022 funding articles, both of which hyperlink the company name directly to https://atomic.financial/. None of these sources associate this Salt Lake City company with brokerage-as-a-service, equity compensation, or David Dindi -- the 'embedded investing' descriptor sometimes attached to a company called 'Atomic' or 'Atomic Invest' appears to refer to the different, unrelated David Dindi-led company described above, not to this one. Given the source database's note describing profile_id 10072967 as possibly "Atomic Invest / brokerage-as-a-service / equity compensation," this appears to be a mischaracterization or conflation with that separate company; based on all evidence gathered here, atomic.financial itself has no self-described brokerage, equity-compensation or 'Invest' product line as of 2026 (a direct text search of its own site turned up no mentions of 'brokerage,' 'equity comp' or 'broker-dealer').

Founding story: Atomic was founded in 2019 by repeat fintech entrepreneurs Jordan Wright and Scott Weinert, who had previously founded and built Unbill, which was successfully acquired by Q2 Holdings (per Atomic's own About page; exact date/terms of the Unbill acquisition were not independently confirmed via a second source). As they built Atomic, they were joined by Andrea Martone as a third co-founder (CPO), bringing financial-infrastructure and open-finance expertise. The company pioneered API-based direct deposit switching -- letting a user redirect their paycheck to a new bank account entirely within a fintech app's UI -- before expanding into a broader 'connected banking' platform covering payment-method switching, income/employment verification, tax data, bill management, subscription cancellation, and (via its 'Uplink' product) secure, on-device, credential-free connections to payroll and merchant systems.

Product/customer evolution: A October 2021 TechCrunch profile described Atomic (then ~55 employees) as powering income-connectivity features for neobank customers including Dave and Bond, explicitly noting it did not directly compete with Plaid (which focuses on linking bank accounts rather than payroll/income data). By its March 2022 Series B announcement, Atomic said its APIs powered 70 banks, credit unions and fintech companies -- including Coinbase, Dave and Propel -- reaching more than 120 million Americans (60%+ of the US population), with monthly revenue said to have grown 342% year-over-year as of December 2021 and full-year 2021 revenue up 19.5x. By July 2026 (per a BusinessWire release on an Atomic/Odynn travel-loyalty partnership), Atomic described itself as trusted by over 250 financial institutions and fintech firms, including 9 of the top 10 US financial institutions and 12 of the top 20 fintechs, with its authentication product Uplink enabling secure on-device access to any user-permissioned system 'across any industry' -- a sign the company has broadened its ambitions beyond pure payroll data toward a general account-connectivity/automation layer. Atomic's own site (as of Aug 2026) states $72.4M in total funding, 2019 as its founding year, 6M+ average yearly users, and that 9 of 10 top US financial institutions work with it.
