11 Tribes Ventures Research
Investment Thesis
11 Tribes Ventures is an early-stage venture firm built around a "capital and care" model: the firm evaluates the founder as the core asset and pairs venture capital with explicit investment in founder resilience, organizational health, and capital-efficient company building. The homepage states that 11 Tribes leads rounds for founders who were "built for their market" and describes the firm as a partner invested in the whole founder, not only the company. Its approach page expands that thesis into a Founder Resilience Commitment, where founders receive non-dilutive capital for resources such as executive coaching, therapy, community, and organizational health, and an Operating Partner Platform that pairs founders with seasoned builders. The April 15, 2025 Fund II announcement says the firm rejects a dollars-driven, people-indifferent model and argues that healthy founders can build durable, profitable businesses.
The firm's practical investment lens is capital efficiency. The approach page's strike zone calls for founders who are humble, hungry, and smart, with strong founder-market fit and a pursuit of capital-efficient growth. It also lists revenue of $500K to $2M annually, a target of profitability within 18 months of investment, post-money valuations of $5M to $25M, rounds raising $1M to $3M, and exit outcomes in the $50M to $300M range. The Fund II announcement similarly says Fund II targets resilient, growth-minded entrepreneurs building remarkably capital-efficient businesses and comfortable with exit opportunities between $75M and $250M.
Stage Focus
11 Tribes should be treated primarily as a Seed to Series A investor, with selective pre-seed exposure where founder-market fit and capital efficiency are unusually strong. The official materials use "early-stage" rather than a rigid stage label, but the strike-zone metrics imply companies with early revenue and a concrete financing round rather than idea-stage businesses. External investor directories list the firm around pre-seed, seed, and Series A; recent activity includes CommanderAI's $5M seed round and Circadian Risk's $6M Series A participation. For F4 matching, Seed and Series A are the highest-confidence stages, while Pre-Seed is a lower-confidence adjacent fit.
Check Size
The official site gives round size rather than check size: companies are typically raising $1M to $3M. Fund II is $46M and aims to support roughly 30 companies over 36 months, with 11 Tribes stepping into lead roles in a majority of rounds. Third-party profiles estimate firm-level check sizes around $1M to $1.5M, while Mark Phillips' appearances on The Pitch show much smaller show-specific checks of $5K to $250K that should not be treated as the firm's institutional check size. A practical matching range is therefore roughly $1M to $1.5M, with moderate confidence.
Lead Tendency
The firm now leans toward leading rounds. The Fund II announcement explicitly says the vehicle allows 11 Tribes to become the lead investor in a majority of funding rounds. CommanderAI's November 2025 seed round was led by 11 Tribes Ventures and Watchfire Ventures, which supports the thesis that Fund II is actively taking lead or co-lead positions. The lead tendency should be marked as "leads," with the caveat that the firm will also participate in follow-ons such as Circadian Risk's Series A.
Recent Activity
The most important recent firm-level event is the April 15, 2025 close of Fund II at $46M. The announcement says Fund II followed successful deployment of Fund I, would support about 30 companies over 36 months, and already had nine selected companies: NuTrad, NQS, Legal Karma, Lease Up, GoNanas, Evercycle, Circadian Risk, Kidsy, and Alloy. In November 2025, CommanderAI announced a $5M seed round led by 11 Tribes Ventures and Watchfire Ventures to build AI-powered sales tooling for waste haulers. In February 2026, Circadian Risk announced a $6M Series A led by Arthur Ventures with participation from Roll Tack Ventures, 11 Tribes, and Tamiami Angel Funds. CB Insights also lists GoNanas activity in April 2026, but the source is not strong enough to characterize 11 Tribes' role beyond portfolio-company activity, so the payload keeps GoNanas as a portfolio company rather than an investment event.
Portfolio Highlights
The official portfolio page separates Fund 2 and Fund 1 companies. Fund 2 includes Aisle AI, Alloy, Barometer, Cableteque, Circadian Risk, Commander AI, Evercycle, GoNanas, Kidsy, Lease Up, Legal Karma, NQS, NuTrad, and Watt Data. Fund 1 includes Ascent, Attend, Bloomfilter, Brainspace, Breshna, Cerkl, FailSafe, Gemist, Huntr, Immersed, iRx Reminder, KeyWise AI, Kicky, Kinship, Krepling, Native, Ryze, Scheduler.ai, SenseGrass, and Surv. The mix is broad, but recurring patterns include B2B software, AI-enabled vertical software, risk/security, legal/fintech workflows, health, consumer brands and marketplaces, agtech, and workflow automation.
Team
The management team page lists Mark Phillips as Founder and Managing Partner, Jeff Baxter as General Partner and Head of Platform, Isaac Arnold as Vice President, and Jonathan Woodrow as Senior Analyst. Mark supports investing, fundraising, and operations and founded the firm after his own entrepreneurial experience shaped the founder-resilience thesis. Jeff's platform role is directly tied to the firm's belief that investment into founder resilience leads to more durable and profitable companies. Isaac manages the diligence and investment committee process. Jonathan supports investment evaluation and diligence. The broader platform includes advisory and operating partners with operating backgrounds across software, health care, consumer, risk, payments, agriculture, and organizational leadership.
Decision Process
The best-supported process signal is institutional partnership and investment committee diligence. Isaac Arnold's team biography says he manages the diligence and investment committee process, so the decision process should be modeled as investment_committee rather than solo GP. The Fund II release says 11 Tribes emphasizes the human relationship from the first call and applies meaningful diligence before term sheet negotiations. Decision timeline is not published; a one-month placeholder is a conservative operating assumption for post-revenue seed or Series A rounds and should be treated with low confidence.
Founder Preferences
11 Tribes prefers founders with strong founder-market fit, humility, hunger, intelligence, and a personal orientation toward resilience and sustainable company building. It is unusually explicit about founder wellbeing: the firm wants entrepreneurs who will invest in mental, emotional, spiritual, and organizational health because it sees neglect of relationships, peace, and health as existential company risk. Founders pursuing capital-efficient growth, near-term profitability, disciplined valuation, and plausible strategic exits appear to be a better fit than founders optimizing for blitzscaling, very large venture outcomes, or high-burn growth.
Geographic Focus
The firm is headquartered in the Chicago area, and external profiles describe a focus on early-stage companies in nontraditional technology hubs. The portfolio is U.S.-heavy and includes Midwest, South, and broader U.S. companies rather than a Silicon Valley-only strategy. Geography should be treated as United States with an emphasis on Chicago, Midwest, and other nontraditional U.S. tech hubs. There is insufficient source support to mark a strong international mandate.
