Four Cities Capital Research
Investment Thesis
Four Cities Capital is a Boston-based early-stage venture firm that backs outstanding teams with the ambition to build category-defining technology companies. Its website is a single page with no thesis text. The only stated theme is "Unconstrained", paired with words like Innovation, Ambition, Vision, Audacity and Impact next to each portfolio company. The public description (LinkedIn, third-party profiles) says the firm invests early in teams building around large technological and economic shifts. Third-party profiles say founder Louis Beryl set the firm up from his experience as both an operator and an investor.
Stage Focus
Seed and Series A are the stages most sources agree on. LinkedIn has described the firm as investing at Seed and Pre-Seed, and a separate LinkedIn description says Seed and Series A, so the stage range is not fully settled. Tracked deals include seed rounds (Caseflood.ai, Range Biotechnologies, Runway) and Series A rounds (Kudos, Lawtrades). The firm's own site does not state a stage.
Check Size
Not disclosed on the firm's site. A third-party mention puts Series A checks anywhere from $500K to $25M, which is too wide to use. No check size is recorded in the payload.
Lead Tendency
Mixed. The firm is named as a joint lead on i23's GBP 4.9M seed (Sky News, October 2026) and as lead on Lawtrades' Series A per one tracker, but it appears as a participant in most tracked rounds. Recorded as "both".
Recent Activity
- October 2026: jointly led i23's GBP 4.9M seed (AI-native insurance broking) with Outward VC, Seedcamp and Insiders VC, per Sky News.
- July 2025: Caseflood.ai $3.0M seed (tracker data).
- 2026: partner posts on LinkedIn about portfolio companies Astra (partnership with DoorDash) and CLODO (YC). Partner George Davies also posted about portfolio company Air Space Intelligence's $325M Series C led by Spark Capital.
- Fund status is not stated anywhere I found. One listing refers to "Four Cities Fund II".
Portfolio Highlights
The site lists twelve companies: Air Space Intelligence, Thirty Madison, Deel, Mashgin, SmithRx, Gecko Robotics, Deepgram, Stoke Space, Boom Supersonic, Modern Treasury, Ginkgo Bioworks and Marqeta. Other portfolio names appear in third-party sources (Astra, CLODO, Caseflood.ai, i23, Kudos, Lawtrades, Range Biotechnologies). The mix runs across AI infrastructure, aerospace and hardware, fintech and payments, healthcare services and biology.

The website has no team page content that could be read; names come from startupintros.com and LinkedIn.
Decision Process
Not documented. A small partnership (LinkedIn lists 2-10 employees) with several general partners; treated as a partnership.
Founder Preferences
The site describes "experienced operators/investors backing the founders of tomorrow" and the portfolio words (Ambition, Audacity, Vision) point to founders attacking large, hard problems. No explicit founder criteria are published.
Geographic Focus
Headquartered in Boston, MA (one source lists Newton, MA). Invests globally: the portfolio and recent deals include US and UK companies (i23 is London-based).
Gaps
No site pages for team, approach, ethos or values returned content (the site is a single page). Check size, fund size, AUM and fund status are unknown. Portfolio dates and round stages for the site-listed companies are not given on the site, so none are recorded.
