The short version

Spring Rock is a sponsor group of 8 issuers that PartnerFacts links to one sponsor (shared management entity, similar issuer names, same business address; automatic match from the filings), filing 17 Form D filings between Nov 2021 and Feb 2025.

What this means One team, 8 deal companies, about 4 years of track record in SEC filings. We link the companies because the same people or address appear on their forms — tap "Request a correction" if that is wrong.

Combined reported sold: $20M to 112 investors (latest filing per issuer). Industries as reported: "Other" (8). Issuers are based in IL (5), HI (3).

What this means $20M raised across the group, about $178K per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Rock Capital LLC Spring (8 issuers, executive officer).

What this means 8 deals for a one-person team on paper. The person on the most companies is usually the one running the show; their page lists every deal.

Activity: 0 new offerings in the last 12 months; latest filing Feb 13, 2025.

What this means No new raise filed in the past year.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AK, AL, AR, AZ, CA, CT, DE, FINRA, GA, HI, ID, IL, KS, KY, LA, MA, MD, ME, MI, MO, MS, MT, NASAA, NC, ND, NH, NM, NV, OK, OR, PA, RI, SC, SD, TN, TX, VT, WA, WI, WV, WY), property records (NYC, FL, IL and TX counties) — none found.

What this means Nothing turned up where we looked (4 sources). That does not prove there is nothing — it means none was found in those sources on that date.

We compared 17 public filings for Spring Rock and found 4 differences, 1 worth asking the sponsor about: 5 Form Ds were filed more than 15 days after the first sale; and more below.

What this means These are differences between the sponsor's own SEC filings — both values, dates and sources are listed in Key records, section 4. Most have ordinary explanations; ask the sponsor.

Key records

Five things investors ask first. Items still in human review are counted, not shown.

1. Lawsuits

None found in sources searched — federal courts (CourtListener / RECAP), checked Oct 24, 2026

4. Differences between public sources

No comparisons published

What is compared

No public statement by this sponsor group has been collected yet, so there is nothing to compare. Sources compared: the sponsor's own website (known from the issuer's own filings — Form C issuer website, EDGAR company profile — an approved profile claim or Form ADV Item 1.I of its matched adviser) · SEC Form D · SEC Form ADV (IAPD) · Internet Archive · No website is on file for this sponsor group yet.

4 differences found between the filings for Spring Rock — 1 worth asking about (compared 17 filings on Oct 24, 2026)

Worth asking · May 14, 2021 – Apr 14, 2022

5 Form Ds were filed more than 15 days after the first sale

Form D filed 146 days after the first sale — SPRING ROCK VENTURE PARTNERS II LP · Form D filed 173 days after the first sale — SPRING ROCK VENTURE PARTNERS I LP · Form D filed 113 days after the first sale — SPRING ROCK VENTURE PARTNERS I LP · Form D filed 24 days after the first sale — SPRING ROCK VENTURE PARTNERS IV LP · Form D filed 25 days after the first sale — SPRING ROCK SECURITY PARTNERS III LP

What this means Late notices are common and carry no penalty by themselves. A pattern of late paperwork is worth asking the sponsor about.

Offering amount changed between filings — SPRING ROCK VENTURE PARTNERS V LP · Offering amount changed between filings — SPRING ROCK VENTURE PARTNERS III LP · Offering amount changed between filings — SPRING ROCK VENTURE PARTNERS V LP · Offering amount changed between filings — SPRING ROCK VENTURE PARTNERS V LP

5 issuers use a registered-agent or shared-office address

Address on file is a registered agent / shared office — SPRING ROCK MANUFACTURING PARTNERS I-A LP · Address on file is a registered agent / shared office — Spring Rock Manufacturing Partners II LP · Address on file is a registered agent / shared office — SPRING ROCK VENTURE PARTNERS IV LP · Address on file is a registered agent / shared office — SPRING ROCK SECURITY PARTNERS III LP · Address on file is a registered agent / shared office — SPRING ROCK VENTURE PARTNERS I LP

What this means A registered agent's address is a mailbox, not where the team works. Ask where the business operates.

Sources
Note · Nov 3, 2021 – Feb 13, 2025

Member companies list addresses in 2 different states

IL (5), HI (3). 5 members use a registered-agent or shared-office address: SPRING ROCK SECURITY PARTNERS III LP (4457 Clausen Avenue, Western Springs, IL); SPRING ROCK VENTURE PARTNERS I LP (4457 Clausen Avenue, Western Springs, IL); SPRING ROCK VENTURE PARTNERS IV LP (4457 Clausen Avenue, Western Springs, IL); Spring Rock Manufacturing Partners II LP (4457 Clausen Avenue, Western Springs, IL).

What this means A registered agent's address is a mailbox, not where the team works. The other address is more likely the real office — ask which one is.

Sources
What is compared

What is compared: every Form D and D/A we hold for this subject, side by side — filing dates vs. first-sale dates (the 15-day rule), amendment timing on open offerings (the yearly-amendment expectation), amounts sold, investor counts, offering amounts and minimums across amendments, industry and size bands, addresses, how each person's name and role is written, paid sellers' CRD numbers, and (for groups) where the member companies were formed and sit. Everything is as filed by the issuer; the SEC does not check it. Differences are common and usually have ordinary explanations — we show both values, the dates, and the source so you can ask. As of Oct 24, 2026.

5. Money to insiders

None reported on 13 offerings — no sales commissions, finder's fees or proceeds to insiders

Counts come from Form D Items 12–15 on the filings in our index (latest filing per offering; one offering = one SEC file number; an amendment updates its offering rather than adding one). "To insiders" = gross proceeds used for payments to executive officers, directors or promoters. "—" = not reported on that filing. Amounts marked (est.) were reported as estimates. "Paid to sell it" = sales compensation recipients named on that filing (Item 12), each linked to FINRA BrokerCheck when a CRD number is reported.

Counted across all 8 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
