Ex-SpaceX engineer raises $24M to bring off-grid desalination to consumers with a $749 device

Vital Lyfe is betting that desalination's core problem isn't physics — it's manufacturing economics. Jonathan Criss, founder and CEO, spent 13 years at SpaceX, starting on Dragon crew reuse before moving to Starlink where he worked on high-volume production at scale. That manufacturing background is the explicit foundation for what Vital Lyfe is building: a consumer-grade reverse osmosis device that converts saltwater, brackish water, or well water into potable drinking water, priced at $749, with preorders currently available for $88 (fully refundable).

The product

The device — called Access — processes six gallons of ocean water per hour and runs on AC or DC power with an integrated battery. On ocean water, the battery lasts roughly an hour; on fresher source water, closer to three hours. It integrates with solar panels for fully off-grid operation. Criss says the company's Torrance, California facility can produce more Access units in a single month than currently exist in the market.

“I was at SpaceX for thirteen years before this. The question that every eight year old kid has — how could there possibly be water scarcity when there's oceans everywhere? If we apply the lessons we learned on Starlink with high rate manufacturing, driving down the cost, and really delivering this technology to everyone, we can make that meaningful impact.”

Why small instead of large

Conventional desalination economics push toward massive centralized plants because high upfront capital costs require enormous throughput to justify. Criss inverts the model: keep unit cost low enough that the economics work at small scale, then multiply across many units rather than scaling up a single system. His comparison is Starlink versus the $10 billion government broadband infrastructure bill that still left rural areas unserved — Starlink reached those customers at a fraction of the cost by distributing the infrastructure.

One environmental concern often raised about desalination is brine disposal. Vital Lyfe's system runs at a low 15–20% recovery rate, producing a dilute concentrate that Criss says dissipates quickly when returned to any source body larger than roughly five gallons.

Revenue mix

Criss is explicit that this isn't purely a consumer play. The U.S. military has a documented water logistics problem — he says half of all casualties from Iraq and Afghanistan were linked to convoys moving water and fuel. NGOs and humanitarian organizations are almost entirely reliant on bottled water logistics. Both are active conversations, with partnership announcements described as forthcoming. But consumer is the deliberate first priority, following Elon Musk's standing advice to Starlink teams: go direct-to-consumer first because it delivers the fastest, harshest feedback.

Company snapshot

Vital Lyfe closed a $24M raise from General Catalyst and Interlagos toward the end of 2024. The company is just over a year old, operates out of a 37,000 square foot facility in Torrance, and has 37 full-time employees plus contractors. First PCBs were arriving imminently at the time of the conversation, with production expected to begin within weeks and full-rate manufacturing targeted for summer 2025.

The unit economics hinge on holding energy and maintenance costs low enough that a sub-$1,000 device generates acceptable margins at consumer price points. That thesis is unproven at production volume, but Criss's claim that his facility can already out-produce the existing installed base, if accurate, suggests the manufacturing cost curve is moving in the right direction.
