Accomplice Research
Investment Thesis
Accomplice describes itself as "a venture firm and contemporary family office" that is "high conviction, concentrated, patient investors." Founded in Boston in 2015 by Jeff Fagnan and Ryan Moore as a spinout from Atlas Venture's technology team, the firm built its early reputation as one of the most active seed-stage investors in New England, backing founders from company origin and staying close to the cap table across the company's life. The public-facing thesis is deliberately spare: rather than a detailed sector playbook, the firm leans on its own track record — citing that it has "been part of the origin story of" a long list of category-defining companies (AngelList, DraftKings, Patreon, WHOOP, Recorded Future, Hopper) — as the clearest statement of what it looks for. The "concentrated" language, paired with a public 2022 announcement that its $405M fund would be its "last fund, best fund," signals a firm optimizing for fewer, higher-conviction bets over a broad, programmatic seed strategy.
Sector Focus
Accomplice's historical portfolio is a generalist spread across cybersecurity (Carbon Black, Recorded Future, SecurityScorecard, Veracode), fintech/crypto (CoinList, FalconX, Near, Orchard), consumer and media (DraftKings, Patreon, Zoopla), travel (Hopper), digital health (PillPack, ZOE, and the 2026 investment in Ayble Health), HR tech (WorkHuman), proptech (HQO), adtech (Integral Ad Science), and SMB software (Freshbooks). The firm also runs a dedicated crypto/web3 vehicle, Accomplice Blockchain, which was behind the 2026 seed investment in Chomp, a social belief-mapping game. There is no evidence of a narrow current thesis; the pattern reads as broad early-stage technology investing anchored in the Boston ecosystem with selective crypto activity through the Blockchain arm.
Stage Focus
Accomplice is historically seed-led ("well known as a founding investor" per Jeff Fagnan's bio) but has followed portfolio companies into much later rounds — Ryan Moore is described as having "sourced and facilitated each of the company's fundraising rounds" for at least one portfolio company, including a $27M round with Kleiner Perkins and DST as co-investors. Recent 2026 activity (Ayble Health's Series A, Chomp's seed) shows the firm still writing checks at seed through Series A as a participant rather than sole lead.
Check Size
No check size range is published on the firm's site or in secondary sources with enough specificity to state confidently. Historical fund sizes ($200M for Fund I in 2015, $405M for the "last fund" in 2022) and a portfolio that spans pre-seed startups to unicorns (WHOOP, DraftKings) suggest a wide range from small seed checks up through larger, concentrated follow-on positions. Treat any specific number as a low-confidence estimate pending direct confirmation.
Lead Tendency
Mixed. The firm was clearly a lead/originating investor on many of its flagship wins (its own language: "part of the origin story of"), but the two verified 2026 investments (Ayble Health, Chomp) both show Accomplice as a participant in rounds led by other firms (Neon; Jsquare/BlueYard). Lead tendency is recorded as "both" pending more recent lead-round evidence.
Recent Activity
Fund status reads as actively deploying despite the 2022 "last fund" framing: Accomplice (via its main fund) participated in Ayble Health's $16M Series A announced September 16, 2026, and Accomplice Blockchain participated in Chomp's $3.6M seed round announced August 27, 2026. A significant team change occurred October 9, 2025, when founding partner Ryan Moore departed to found Revenant VC, a venture-secondaries firm — leaving Jeff Fagnan as the sole publicly confirmed active partner at Accomplice as of this research.
Portfolio Highlights
Accomplice's public "origin story" list includes AngelList, Carbon Black (acquired by VMware), Caribou, CoinList, DraftKings, FalconX, Freshbooks, Hopper, HQO, Integral Ad Science, Kodiak Labs, Near, Orchard, Patreon, PillPack, Recorded Future, SecurityScorecard, Veracode, WorkHuman, WHOOP, ZOE, and Zoopla. Jeff Fagnan's personal bio adds Datacamp and Teachable to his individual portfolio. The firm is also an anchor LP behind several solo-GP funds it helped seed as part of a "federated VC model" — Spearhead (with AngelList), Archetype, Vinyl, Vibe, and Wolfhead — though these are LP positions in other funds, not direct portfolio companies.
Team
- Jeff Fagnan, Founding Partner — Co-founder of Accomplice (spun out of Atlas Venture's technology practice in 2015) and also founder of Spearhead, Maiden Lane, BOSS (Boston Syndicate), TUGG (Technology Underwriting Greater Good), TINT, and REV Boston. Long track record as an early/originating investor across the firm's portfolio.
- Ryan Moore, Founding Partner (departed October 2025) — Co-founder of Accomplice; sourced and facilitated fundraising across much of the early portfolio and sat on boards including DraftKings, WorkHuman, and Caribou. Left in October 2025 to found Revenant VC, a venture-secondaries firm. Included here for historical accuracy; not a current point of contact.
The firm's public site no longer hosts a team/bios index page (the linked "BIOS" page returns a 404), consistent with a leaner, single-partner operating structure post-2025.
Decision Process
Not disclosed, and the post-Ryan-Moore team composition is uncertain enough that "partnership" vs. "solo GP" cannot be confidently assigned. Historically operated as a founding-partner duo with investment decisions made by Fagnan and Moore together.
Founder Preferences
No explicit founder-preference statement is published. The firm's chosen framing — "high conviction, concentrated, patient investors" who worked with portfolio companies "since inception" — suggests a preference for founders it can back early and stay closely engaged with over a long horizon, rather than a spray-and-pray seed strategy.
Geographic Focus
Headquartered in Boston, MA (56 Wareham Street), with deep roots in the New England tech ecosystem, but the portfolio (DraftKings, Near, Zoopla in the UK, FalconX) shows the firm invests well beyond Boston, including internationally.
