Ground-Up Development · Urban Infill · San Diego
Mankind Investment Group is a San Diego family office that develops, builds, and invests in ground-up multifamily real estate. We are operators first — relentlessly focused on efficiency, execution, and value.
Our Approach
We are active builders and developers — not passive allocators. Mankind Investment Group was founded by operators who spent 15 years building and scaling businesses from the ground up. That same relentless focus on execution, cost efficiency, and value creation now drives everything we do in real estate.
Every project we pursue is by-right — meaning it requires no discretionary approvals, no variance hearings, no political risk. We only build what the zoning already allows. This single discipline eliminates the most common source of schedule slippage and cost overrun in development, and it's non-negotiable for us.
"We are relentlessly passionate about efficiency and value engineering. We are not building the Taj Mahal — we are building value for all stakeholders involved."Jake Risman & Steven Maman · Co-Founders
As trusted stewards of our own capital, we operate with skin in the game on every project. We don't manage other people's money from a distance — we invest alongside our partners, sharing every upside and every risk. Our projects reflect a balance of creativity and execution, delivering lasting value to both our portfolio and the San Diego community.
The margin is made at acquisition. We target by-right, execution-ready sites priced to deliver the return we need — no optionality games, no hope underwriting.
Sub-three-year project cycles are our standard. We avoid entitlement risk entirely — every project is shovel-ready or near-ready before we commit capital.
We are relentless optimizers. Every line item — design, materials, subs, schedule — is interrogated. We cut where we must and value-engineer everywhere possible.
No ego, no overbuilding. We protect capital before we chase yield. If a deal doesn't underwrite to our return threshold, we walk — every time.
We act as GP on our own projects and invest our own capital as LP alongside our partners. Where we can add operational value as Co-GP, we will — and if conviction is high, we'll invest as LP in others' deals too. Alignment isn't a talking point. It's how we're structured.
We develop and operate our own projects end-to-end — from site acquisition through design, permitting, construction, and disposition. As GP, we bring the full operator stack.
Where alignment is strong and our operational expertise creates a clear edge, we partner as Co-GP — contributing network, execution capability, and capital alongside a lead sponsor.
When underwriting meets our standards and we believe in the operator, we invest as LP. We look for the same discipline in others that we apply to ourselves: by-right, short cycle, acquire right.

Jake Risman and Steven Maman have been building companies together for 15 years. They have launched, scaled, and successfully exited multiple businesses — each time applying the same obsessive focus on efficiency, optimization, and execution that now defines Mankind Investment Group.
Real estate was always part of their portfolio. After their last exit, they decided to go deeper — to become operators in the space they had long invested in passively. The family office was founded with a simple thesis: build the right projects, in the right market, with the right discipline.
Jake is a serial entrepreneur with a proven track record of building businesses from zero to acquisition. He co-founded 10DollarMall and ModDeals, growing the operation to over 10 million units sold annually before a 2015 exit. He then co-founded Upstream — a reverse logistics platform serving Amazon, Macy's, and Foot Locker — which was acquired by a private equity firm in 2020. Jake brings a founder's relentlessness and an operator's execution to every Mankind project.
Steven has partnered with Jake across every venture for 15 years, focused on strategic vision, systems thinking, and operational excellence. After their e-commerce and logistics exits, Steven and Jake were brought on to build software and supply chain infrastructure for the nation's largest VC-backed cannabis wholesale platform. His cross-industry depth now informs Mankind's forward-thinking, efficiency-driven approach to development.
