Startup funding on October 28, 2026
19 companies raised: 10 filing for the first time, 9 again · 27 with a profile. Together they reported $120.9 million in new offerings in Form D filings the SEC accepted on Wednesday, October 28, 2026. The largest was Energy Materials Corp, with $41.6M from 21 investors.
27 companies filed on Oct 28: 19 reported new money, which makes up the day's total; 7 only amended earlier filings; 1 only filed late for offerings that began more than a year earlier (listed below the table). We also leave out 20 companies: four listed on a stock exchange, four based outside the US, one reporting a merger or spin-off rather than a raise and 11 that are not startups by our rules (banks, insurance accounts, clinics, funds' vehicles, old offerings). All Form D filings counts everything the SEC accepted that day, including investment funds and real estate offerings, which we leave out when counting.

- Location is the address under “Principal Place of Business and Contact Information” on the filing, not the “Jurisdiction of Incorporation/Organization”. Most startups incorporate in Delaware but work somewhere else.
- First sale is the day the first investor committed, which can be months before the filing date. Not yet means the company filed before that day came, so the amount sold is $0 for now; it shows up when the company amends the filing.
- $0 next to a first-sale date means an investor had committed but no money had come in when the company filed.
- New is a company's first filing for an offering. Amended updates an earlier filing, usually because more money came in, and shows the new total; that money was already counted when it was first reported.
- One company filed more than once that day, usually amendments to separate offerings. Each company is listed once; open “more filings” to see the others.
Late filings, not in the day's total
New filings for offerings whose first sale came more than a year before Oct 28. The filing is new, but the money was raised long before.
- SymKardia, Inc.: one filing for an offering first sold on Jan 10, 2025 ($4.0M).
