The short version

Michael Dybbs is listed as a director on 17 SEC Form D filings by 9 issuers between Jul 2013 and Aug 2026. Largest by amount reported sold: Samsara BioCapital, L.P. (Palo Alto, CA — pooled investment fund — 2017–2020; $310.1M reported sold to 57 investors), Delfi Diagnostics, Inc. (Palo Alto, CA — biotechnology — 2022–2025; $225M reported sold to 50 investors), Samsara Opportunity Fund, L.P. (Palo Alto, CA — pooled investment fund — 2025; $98M reported sold to 19 investors), SUTRO BIOPHARMA INC (South San Francisco, CA — biotechnology — 2018; $85.4M reported sold to 15 investors), Claris Biotherapeutics, Inc. (Half Moon Bay, CA — biotechnology — 2026; $55.7M reported sold to 14 investors) and 4 more (all listed below).

What this means A repeat sponsor — 9 separate companies raised money with this person listed as director, over about 13 years. Across those companies the filings report $931.4M sold in total.

Listed alongside Srinivas Akkaraju (9 shared filings), Anthony Sun (4 shared filings), Edmon Jennings (4 shared filings), Francesco de Rubertis (4 shared filings), Jeffrey Cleland (4 shared filings) and 54 others.

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

The issuers belong to 2 sponsor groups: Aravive (2 issuers, $41.9M reported sold, 2011–2022) and Fs Analytics (2 issuers, $98M reported sold, 2023–2025).

What this means This person is listed across more than one sponsor team; each group page shows that team's full track record.

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) — none found.

What this means Nothing turned up where we looked (3 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 Michael Dybbs and found 11 differences, 1 worth asking the sponsor about: 4 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.

4 offerings have no amendment in the last 12 months and may still be open

(latest filing Aug 4, 2015)

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

Sources
Note · Jun 6, 2018 – Aug 8, 2018

Same name, different state: "Michael Dybbs" (MA) is a separate record

This page covers filings where the address state is CA or MD. A separate record, "Michael Dybbs" with address state MA, is listed on 2 filings — most recently by Abcuro, Inc. (Aug 13, 2026). Both records have filings in the same period (Feb 19, 2025 to Aug 12, 2026).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

Same name, different state: "Michael Dybbs" (IL) is a separate record

This page covers filings where the address state is CA or MD. A separate record, "Michael Dybbs" with address state IL, is listed on 2 filings — most recently by Levo Therapeutics, Inc. (Nov 25, 2019). Both records have filings in the same period (Nov 25, 2019).

What this means Two records with one name were active at the same time. That can be one person listing different company addresses, or two different people. We keep them apart until a filing ties them together. Check both pages before you decide.

Sources
Note · Jul 25, 2022 – Dec 18, 2025

Address moved from Baltimore, MD to Palo Alto, CA — Delfi Diagnostics, Inc.

The people listed on the Jul 25, 2022 filing give Baltimore, MD; on the Dec 18, 2025 filing they give Palo Alto, CA.

What this means Businesses move; this just shows the two places and dates. If you were told one city and the forms say another, ask which is current.

Sources
Note · Jul 22, 2013 – Aug 12, 2026

Michael Dybbs is listed with 2 different address states: CA, MD

CA on 16 filings (Jul 22, 2013 to Aug 12, 2026); MD on 1 filing (Jul 25, 2022).

What this means The address on a Form D is usually the company's, not the person's home, so this often just reflects different companies. It can also mean a move. Nothing wrong by itself.

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.

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).
