The short version

Ra Capital Nexus is a sponsor group of 13 issuers that PartnerFacts links to one sponsor (shared people, shared management entity, same business address, similar issuer names; automatic match from the filings), filing 60 Form D filings between Feb 2009 and Apr 2026.

What this means One team, 13 deal companies, about 17 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: $8.91B to 1,665 investors (latest filing per issuer). Industries as reported: Pooled Investment Fund (13). Issuers are based in MA (12), Cayman Islands (as filed: E9) (1).

What this means $8.91B raised across the group, about $5.35M per investor. Amounts come from each company's latest Form D; they are what the sponsor reported, not audited figures.

Principal people: Peter Kolchinsky (13 issuers, executive officer, director, and promoter), Rajeev Shah (12 issuers, executive officer, director, and promoter), RA Capital Management, L.P. (3 issuers, executive officer and promoter, entity), Brigid O'Brien (2 issuers, executive officer), Kyle Teamey (2 issuers, executive officer) and 17 more.

What this means 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 Apr 20, 2026.

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

Adviser registration (Form ADV) on record: RA CAPITAL MANAGEMENT, LP.

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA), property records (NYC, FL, IL and TX counties) — 2 court cases matching the name listed in Key records below.

What this means 2 records came back, including 1 court case still open — open cases can take years and cost money. Each one is listed below with a link to the original document and a line saying why it matched. A name match is not proof it is the same person or company — read the why line and the document. Being sued or named in a release is an accusation, not a finding.

We compared the newest 50 of 60 public filings for Ra Capital Nexus and found 19 differences, 1 worth asking the sponsor about: 9 people are no longer listed on a later amendment; 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.

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. We compared the newest 50 of 60 filings (work cap); older filings are not covered here. As of Oct 24, 2026.

How this is counted

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 13 issuers in this group — every filing in our index, latest filing per offering (SEC file number).
