Close to founders, early.
Our earliest exposure comes two ways: small angel checks into operators we know, and LP positions in a select set of startup funds. Both keep us close to founders at the edge of an industry, which is how we come to understand companies years before they reach the public markets.
Angel checks
We're not running a venture fund. Angel investing is adjacent to everything else we do: it gives us exposure to ideas earlier than we'd otherwise have it, and it surfaces the growth-stage companies that mature out of those relationships. We invest small, in operators we've worked with or whose work we've followed closely. We meet many of them at SF Patchworks, our incubator in San Francisco for technical founders.
Cypress Battery
A domestic battery backup unit (BBU) assembly built for the high-power discharge AI data centers need at the rack level. As racks demand more power density, the integrators tuned for that should beat the incumbents built for steady-state.
Tribe.ai
AI adoption is bottlenecked on talent; Tribe is the expert network that unblocks it.
Neuralace
Personal brain-computer interfaces are around the corner, and this is the team building them.
Marathon Fusion
Fusion's unsolved bottleneck is the fuel cycle, and Marathon is solving it.
Fleetworks
AI voice agents for the phone-call grind of freight brokerage.
Trayd
A back-office OS for construction's specialty trades: union rules, prevailing wages, and same-day pay.
Swiftlane
Access control for offices and apartments, rebuilt software-first around face recognition.
Serene Sleep
A 15-minute palatal implant for snoring and mild sleep apnea, no masks or surgery required.
Needle
An ad agency replacement that ships faster and costs less.
Ariglad
Turns the answers buried in support tickets into a self-maintaining knowledge base.
Triply
The operating system for travel agencies, built in Nairobi for the African market.
VClub
An AI-native poker coach vertically integrated with card-reading hardware, a card room in Toronto where founders and operators play together, and camps taught by poker pros.
Assured
Agentic AI for healthcare provider credentialing, automating the verification workflow that gates a new healthcare worker's ability to practice. It takes on one of healthcare's oldest back-office bottlenecks, just as healthcare workers are practicing across more states, startups, and virtual venues.
PathOn Robotics
One open-source software and sensor stack built to run on any robot, plus their own reference hardware 6-DOF arm, symmetric gripper, dexterous hand. As more hardware comes online, the platform layer wins: the team that owns the universal control stack captures more value than any single robot maker.
GenProof
An agent that proves the correctness of code, pairing a specialized LLM with the Isabelle prover to generate mathematical proofs over every execution path. The bottleneck is shifting from generation to verification: as AI writes more software, the tooling that closes that gap becomes infrastructure.
Apero
Modern operating software for medical practices, scheduling, visit notes, RCM, patient billing, and prescriptions in one platform, built by operators from Doctor on Demand. The back office of independent medicine has been under-tooled for decades.
LP positions
Beyond what we back directly, Milton Maxwell is a limited partner in startup funds, almost all early-stage. We don't back funds for diversification's sake. We back funds whose managers are exceptional, whose strategies reach corners of the market we can't cover ourselves, and whose deal flow and judgment make us better investors.
South Park Commons (SPC) Fund
A community-first fund that backs technical founders before they have a company, at the "pre-idea" stage. Being an LP keeps us close to a dense network of operators at the exact moment they're forming the next set of theses.
Iterative
Y Combinator's accelerator model, ported to Southeast Asia. Gives us reach into a region whose manufacturing, capital flows, and consumer markets increasingly matter to our public-equity thesis, exposure we couldn't build ourselves from San Francisco.
Banana Capital
Turner Novak's solo-GP fund, writing small early checks into internet-first founders.
AngelList Access Fund
AngelList's flagship wrapper: broad exposure to its syndicates and rolling funds.
Mission St Capital
An early-stage generalist fund grown out of the Mission Control hacker house.
Seven Hill Ventures
An early-stage cybersecurity fund founded by Michael Coates (3x CISO at Twitter, Mozilla, and CoinList). Backs technical founders building security tooling for a post-AI world.
Sweet Spot Capital
A pre-seed fund led by Allen Gannett (founder of TrackMaven, author of The Creative Curve). Allen applies the same framework from the book to founder selection, looking for people doing breakout creative work in the narrow band between the familiar and the genuinely new.
