The 81 Collection Research

Investment Thesis

The 81 Collection is a Chicago-based growth equity and venture firm founded in 2021 by Vijen Patel, built on the premise that 81% of U.S. GDP sits in overlooked, foundational industries that receive a disproportionately small share of venture and growth capital. The firm organizes its thesis around four pillars: "Boring Services" (low-margin sectors like recycling and nursing-home modernization), "Hard Work" (capital-intensive, blue-collar industries in need of digitization), "Unpleasant Spaces" (physical-world infrastructure resistant to change, including real estate, IoT, and automation), and "Inequitable Structures" (red-tape-heavy sectors such as education, government, and social assistance). The founding team built and operated companies in these foundational industries, citing roughly $40 billion of value created and 40,000 employees whose earnings improved as a result.

Stage Focus

The 81 Collection invests at Pre-Seed, Seed, and Series A. It positions itself as a founder-friendly, first-institutional-check partner for operators tackling industries that traditional venture largely ignores.

Check Size

Public fund-criteria sources put the range at roughly $100K-$2M per check, with some sources citing initial checks as large as $1.5M and a sweet spot near $250K. Treat the exact number with moderate confidence; the firm does not publish a check-size range on its own site.

Lead Tendency

The 81 Collection has led at least one recent strategic investment (Uptiv Health, December 2025), and press describes it as a "growth equity firm focused on modernizing overlooked sectors" leading that round. Lead tendency is best read as "leads" for strategic/growth-stage checks, though the firm also participates alongside other investors (e.g., Redesign Health co-invested in Uptiv Health).

Recent Activity

The firm's first fund, a $41M vehicle, was announced in December 2022, with more than two-thirds of the capital raised from current and former founders in the industries it targets. A second vehicle, "81 Collection Fund II," appears in fund-tracking databases (PitchBook, AUM13F) without a disclosed size. Recent known activity includes a strategic investment in Uptiv Health (tech-enabled, hybrid infusion care) in December 2025, and the January 2025 acquisition of portfolio company Mezo (AI-driven residential maintenance triage) by Property Meld.

Portfolio Highlights

Confirmed portfolio companies include Cambium Carbon (fulfills large lumber orders through local mills), Bonside (non-dilutive financing for SMBs), Mezo (AI residential maintenance triage, acquired by Property Meld in January 2025), Grounded (road/logistics industry), and Uptiv Health (hybrid tech-enabled infusion care). The firm's portfolio is intentionally small and concentrated relative to typical seed funds, consistent with its "hard industries" focus.

Team

  • Vijen Patel, Founder & General Partner — Founder of Pressbox (a fabric-care company acquired by Procter & Gamble in 2018); led the re-branded Tide Cleaners as CEO post-acquisition before stepping down in 2020 and founding The 81 Collection in 2021.
  • Alex Kirshenbaum, Vice President — Previously at GTCR; founder of The Helix Partners.
  • Anna Levine, Operating Partner/Advisor — President/COO, Industrious.
  • Mike Evans, Operating Partner/Advisor — Co-Founder, GrubHub.
  • Divey Gulati, Operating Partner/Advisor — Co-Founder, ShipBob.
  • Luke Saunders, Operating Partner/Advisor — Founder/CEO, Farmers Fridge.
  • Dhruv Saxena, Operating Partner/Advisor — Co-Founder, ShipBob.
  • Jamie Ahern, Operating Partner/Advisor — Former COO, Kin.

Beyond this core group, the firm maintains "The Collective," a network of 100+ operator-investors and advisors drawn from companies including GrubHub, Uber, Rinse, ShipBob, Farmers Fridge, Home Chef, Tock, Drizly, Custom Ink, Tecovas, Relativity, and M1, who are positioned to help portfolio companies navigate "hard industries" faster than the typical multi-year bootstrapping path.

Decision Process

Not explicitly disclosed. Given the two-person GP/VP core team supplemented by an operating-partner network, decisions likely run through a small partnership rather than a large investment committee.

Founder Preferences

The firm favors operator-founders tackling "unsexy," capital-intensive, or highly regulated industries where deep operating experience is a differentiator, similar to Vijen Patel's own background scaling Pressbox/Tide Cleaners. The 81 Collection's value proposition centers on its Collective of 100+ founder-advisors who have personally operated in the same categories as target portfolio companies.

Geographic Focus

U.S.-focused, headquartered in Chicago, IL, with a thesis explicitly framed around the U.S. GDP composition. No specific regional restriction is stated beyond a domestic focus.
