New Jersey Innovation Evergreen Fund (NJIEF)
The New Jersey Innovation Evergreen Fund (NJIEF) is a state co-investment program run by the New Jersey Economic Development Authority, not a private venture fund. NJIEF raises money by auctioning New Jersey corporate tax credits, then invests it alongside approved venture firms in early-stage companies. As of 2026, its only tracked water holding is microplastics-filtration startup PolyGone Systems.

The take
The New Jersey Innovation Evergreen Fund is one of the rare investors I track that is really a piece of state economic policy wearing a venture-fund costume. Created under New Jersey's 2020 Economic Recovery Act and run by the state's Economic Development Authority (NJEDA), NJIEF raises its money in an unusual way: the state auctions off New Jersey corporate tax credits, companies buy them to cut their tax bills, and the proceeds become public capital that NJIEF invests alongside approved private venture firms in young New Jersey companies.
NJIEF does not pick winners on its own. It co-invests through a roster of around thirty approved firms it calls Qualified Venture Firms, matching their cheques rather than leading rounds, so the state shares the upside in companies that keep their headquarters and jobs in New Jersey. The program is authorised to deploy up to 600 million dollars over its life; as of December 2025 the NJEDA approved a fresh 85 million dollars of tax-credit sales to refill it, and by March 2026 NJIEF had put 4.65 million dollars into five New Jersey businesses in a single batch of approvals.
The reason NJIEF turns up in my water database at all is a single company: PolyGone Systems, a Princeton University spin-out based in Kearny that is going after one of the least glamorous problems in water, the microplastics slipping straight through conventional treatment plants. PolyGone's patented Artificial Root Filter mimics the roots of aquatic plants to trap plastic particles smaller than a millimetre from treated effluent, reservoirs and rivers, and the company runs a removal pilot with a New Jersey utility while selling microplastics water-testing on the side.
So the honest read, if you arrived expecting a water fund, is that NJIEF is not one. NJIEF is a state co-investment vehicle whose mandate is New Jersey jobs across every innovative sector, from therapeutics to fintech, and PolyGone is its lone water bet so far, backed across two co-investments alongside its venture-firm partners. (don't) Waste Water rates NJIEF's water commitment Occasional for exactly that reason. If the state writes another water cheque, expect it to look like PolyGone: a New Jersey company, an approved firm leading, and the public money matching the private.

- How does the NJ Innovation Evergreen Fund work?
- The NJ Innovation Evergreen Fund works by auctioning New Jersey corporate tax credits, which corporations buy to reduce their state tax bills. NJEDA turns those proceeds into public investment capital and co-invests it, alongside a roster of approved Qualified Venture Firms, into high-growth companies that keep jobs in New Jersey.
- Who runs the New Jersey Innovation Evergreen Fund?
- The New Jersey Innovation Evergreen Fund is administered by the New Jersey Economic Development Authority (NJEDA), the state's economic-development agency, based in Trenton. NJIEF has no private general partners; investment decisions flow through its approved Qualified Venture Firms, which source deals and invest their own capital alongside the state.
- Is NJIEF a normal 'evergreen' venture fund?
- Despite the name, NJIEF is not a conventional evergreen fund. A normal evergreen fund is an open-ended private vehicle that recycles its returns with no fixed end date.
