Background

Fred Seibert is an American media executive, animation producer, and angel investor whose career spans music, cable television, animation, and early-stage technology investing. He attended Columbia University starting in 1969, where he spent most of his time at college radio station WKCR-FM and never graduated 1.

Seibert began as a jazz and blues record producer in the early 1970s, co-founding the independent label Oblivion Records around 1972 with Tom Pomposello and Dick Pennington, producing albums by Mississippi Fred McDowell and Joe Lee Wilson 1. He received a Grammy Award nomination at the 20th Annual Grammy Awards 1.

In 1981, Seibert served as MTV’s first creative director during the channel’s August 1, 1981 launch, working with the Manhattan Design collective to create the iconic MTV logo and contributing to the “I Want My MTV!” advertising campaign 1 2. In 1983, he co-founded the media branding agency Fred/Alan Inc. with Alan Goodman; together they revitalized Nickelodeon between June 1984 and January 1985 — Fred/Alan’s own description is that they took the network “from worst to first in the ratings in six months” — and created the Nick-at-Nite concept in 1985, the launch positioning for Comedy Central, and the launch of VH-1 1 2.

From 1992 to 1996, Seibert served as the final president of Hanna-Barbera, where in 1994 he established the animation incubator anthology What a Cartoon!, a 48-short program that launched Dexter’s Laboratory (Genndy Tartakovsky), Cow and Chicken (David Feiss), Johnny Bravo (Van Partible), Courage the Cowardly Dog (John R. Dilworth), and The Powerpuff Girls (Craig McCracken) — properties that became Cartoon Network’s early original-programming franchise 1.

In 1998 Seibert founded Frederator Studios, an independent animation company that produced My Life as a Teenage Robot for Nickelodeon, Adventure Time for Cartoon Network, and Castlevania for Netflix 1. In March 1999, MTV Networks CEO Tom Freston appointed Seibert as the first president of MTV Networks Online 1. In 2007, Seibert co-founded the early internet-video company Next New Networks, which was acquired by YouTube in March 2011 1 2. He also co-founded the New York-based studio Thirty Labs in 2014 with John Borthwick (Betaworks), Jonathan Miller, and Shari Redstone 1.

Seibert stepped down as Frederator’s CEO in August 2020 but remained executive producer on ongoing projects 1. On February 23, 2021, he announced the formation of FredFilms with a first-look deal at VIS Kids 1 2.

In 2004, then-unknown teenage developer David Karp began interning at Frederator Studios’ New York office, where Karp built Frederator’s first multi-user blogging platform 1 3. In late 2006, Seibert introduced Karp to Spark Capital’s Bijan Sabet — Sabet had previously invested in one of Seibert’s projects — which led to Spark co-leading Tumblr’s $750,000 Series A in October 2007 alongside Union Square Ventures 4 3. Tumblr itself launched in February 2007 from a rented desk at Frederator’s Park Avenue South offices 1 3. Seibert was one of Tumblr’s first bloggers, an angel investor in the company, and served on Tumblr’s board of directors before the platform’s $1.1 billion acquisition by Yahoo in May 2013 1 3.

Stated Thesis

Seibert has not published a formal angel investing thesis. The closest available signals are operating-philosophy statements he has made publicly about creative work and the kinds of people he is drawn to.

FredFilms summarizes his approach across his career phases under the tagline “Stay Original. Always.” 2. Asked to describe what draws him to projects and people, Seibert has said: “I’m attracted to community, to places where disenfranchised people find what they love…I’m attracted to crazy.” 2

These are operator-era statements about creative talent, not investment criteria. Founders should read them as biographical context rather than as a published investing thesis.

Inferred Thesis

Sample size caveat: only 3 angel investments are independently verifiable from contemporaneous press and aggregator data (Tumblr, Sawhorse Media, Storybird). CB Insights publicly lists 3 investments in total 5. This sample is too small to support sector or stage percentages — the inferred thesis below is qualitative.

Across the verified investments, several patterns are clear:

  • Consumer creative-tools and community media. Tumblr (free-form blogging), Sawhorse Media (Shorty Awards, Muck Rack — tools for journalists and creators), and Storybird (visual storytelling tool with an education skew) are all consumer or prosumer products centered on user-generated creative expression. None are enterprise infrastructure, fintech, or deep tech.
  • New York-based founders he knew personally. Tumblr was built inside Frederator’s NYC office by an intern Seibert had mentored for years 1 3. Sawhorse Media (Greg Galant, NYC) and Storybird (Mark Ury, NYC) are also New York companies 5 6. Seibert’s angel checks track his physical and personal network rather than broad sector sourcing.
  • Board involvement, not just capital. Seibert held a board seat at Tumblr through the Yahoo acquisition 1 3 and remains on the board of directors of Sawhorse Media 1. He behaves more like a hands-on operator-investor than a passive capital allocator.
  • Cadence is sparse, operator-paced. The three verified deals span 2007 (Tumblr seed), 2010 (Sawhorse seed), and 2013 (Storybird Series A) — roughly one investment every three years. Seibert’s angel activity does not match the deal velocity of dedicated angels or solo GPs.
  • No publicly verified new investment after August 2013. CB Insights lists Storybird as his most recent investment 5. His operating bandwidth since 2014 has been directed at Channel Frederator Network, Thirty Labs, the Frederator/WOW Unlimited transaction, and FredFilms.

Active investor signal: weak as of 2026. A founder evaluating Seibert today should treat him as a potentially dormant angel, with his primary professional activity focused on FredFilms and animation production rather than new technology investing. Any current engagement would more plausibly come through his animation/media network than as a structured angel check.

Portfolio

Company Year Stage Source
Tumblr 2007 Seed (one of the first individual angels; later board member) 1 3
Sawhorse Media (Muck Rack / Shorty Awards) 2010 Seed (original angel investor; board of directors) 1
Storybird 2013-08-01 Series A ($2.5M, alongside Lerer Hippeau, Index Ventures, CAA Ventures, Advancit Capital, Learn Capital, John Maloney) 5 6

CB Insights publicly lists 3 total investments; no additional portfolio companies could be independently verified 5. The portfolio above represents the publicly known angel record. Seibert has also been described in his Wikipedia biography simply as “an angel investor in technology and media-based startup projects” 1 without further enumeration.

In Their Own Words

On what attracts him to projects and people (FredFilms, “About” page):

“I’m attracted to community, to places where disenfranchised people find what they love…I’m attracted to crazy.” 2

On his career-spanning motto, used as the masthead of FredFilms:

“Stay Original. Always.” 2

On the What a Cartoon! incubator model at Hanna-Barbera, which is the closest analogue in his pre-internet career to startup angel investing (Wikipedia summary citing his own framing of the program): Seibert designed What a Cartoon! as an “animation incubator” — a 48-short anthology in which individual creators retained creative control of their pieces, on the bet that backing original creator visions would outperform a traditional studio commissioning model. The bet produced The Powerpuff Girls, Dexter’s Laboratory, Johnny Bravo, and Courage the Cowardly Dog 1.

Note: Seibert has appeared on the Understanding VC podcast discussing his creative-talent frameworks and the story of how Tumblr was created 7, but the episode page was not accessible at the time of research; quotes from that interview are not included here to avoid paraphrase. Founders evaluating Seibert should treat the podcast episode as a primary source to consult directly.

What Founders Say

David Karp, founder of Tumblr, was Seibert’s intern at Frederator from age 14 and built Frederator’s first blogging platform before launching Tumblr from a desk at Frederator’s New York office in 2007 1 3. The MediaShift profile of Karp characterizes Seibert as one of Karp’s primary mentors and as the source of the introduction to Spark Capital’s Bijan Sabet that led to Tumblr’s Series A 3 4. The same profile describes Seibert’s later role on Tumblr’s board as “hands-off” and “a David ally” 3.

Beyond Karp’s case, no independently sourced founder testimonials about working with Fred Seibert as an angel investor or board member were found after dedicated searching.
