The short version

Robert Tepper is listed as an executive officer and director on 36 SEC Form D filings by 15 issuers between Jul 2009 and Jun 2022. Largest by amount reported sold: Third Rock Ventures VI, L.P.

Listed alongside Robert Langer (9 shared filings), Robert Paull (8 shared filings), Anthony Evnin (7 shared filings), Mark Goldsmith (7 shared filings), Alan Crane (6 shared filings) and 110 others.

What this means These are the other officers, directors or promoters the companies named on the same forms — the team around Robert. Each name links to their own page.

The issuers belong to 2 sponsor groups: Third Rock (7 issuers, $2.62B reported sold, 2010–2026) and Bluebird (2 issuers, $245M reported sold, 2010–2022).

Public records searched: federal courts (CourtListener / RECAP), SEC enforcement releases, state securities regulators (AZ, CA, DE, TX, WA) — 7 bankruptcy cases matching the name listed in Key records below.

What this means 7 records came back. 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 36 public filings for Robert Tepper and found 6 differences, 1 worth asking the sponsor about: Investor count went down between filings; 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.

4. Differences between public sources

Comparisons cover issuers and sponsor groups — see the issuer pages under Deals

6 differences found between the filings for Robert Tepper — 1 worth asking about (compared 36 filings on Oct 24, 2026)

Worth asking · Mar 19, 2010 – Apr 27, 2011

Investor count went down between filings — bluebird bio, Inc.

The Mar 19, 2010 filing reports 6 investors; the Apr 27, 2011 Form D/A reports 5 investors.

What this means Investor counts normally only grow. A smaller number can mean investors left or were refunded, or a count was corrected. Ask the sponsor what happened.

Form D (earlier) · Mar 19, 2010 ↗Form D/A (later) · Apr 27, 2011 ↗bluebird bio, Inc. — PartnerFacts page ↗
Sources
Note · Jan 11, 2017 – Dec 13, 2017

Offering amount changed between filings — Neon Therapeutics, Inc.

The Jan 11, 2017 filing says $70,000,000 offered; the Dec 13, 2017 Form D/A says $106,000,001.

What this means The target raise changed. Raising the cap is common when a deal grows; ask whether the extra money has the same terms and use.

Note · Mar 19, 2010 – Apr 27, 2011

Offering amount lowered between filings — bluebird bio, Inc.

The Mar 19, 2010 filing says $47,412,660 offered; the Apr 27, 2011 Form D/A says $37,500,000.

What this means The target raise got smaller. That can mean the plan shrank or the sponsor stopped early. Ask what changed in the deal.

No amendment in the last 12 months on an offering that may still be open — Faze Medicines, Inc. (latest filing Dec 22, 2020) · No amendment in the last 12 months on an offering that may still be open — CONSTELLATION PHARMACEUTICALS INC (latest filing Apr 6, 2018) · No amendment in the last 12 months on an offering that may still be open — Neon Therapeutics, Inc.

(latest filing Dec 10, 2015) · No amendment in the last 12 months on an offering that may still be open — Allena Pharmaceuticals, Inc. (latest filing Nov 13, 2014) · and 5 more

What this means SEC rules expect a yearly amendment while an offering is still going. Ask the sponsor which of these raises have closed.

What this means The issuer described its business differently on different forms. Often it is just a different box ticked; sometimes the deal itself changed. Ask which business your money is in.

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.

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 every filing this person is listed on (latest filing per offering, per issuer).

Deals 15

Every issuer that named Robert Tepper on a Form D, newest first. A Form D is the notice a company files after it starts selling a private investment.
