Ben Stern has spent ten years on factory floors, running a 15,000 square foot personal care manufacturing facility he built out of the company he founded in high school [MaaterMakers; Florida Today, January 2020]. The software he wanted during those years, the kind that could find a replacement supplier before a delayed shipment cascaded into a missed purchase order, did not exist. So in 2024 he started building it. In March 2026, his San Francisco company Tenkara closed a $7 million seed round led by True Ventures, with HF0, WndrCo, Articulate Capital, Night Capital, SF1, Transpose, and a group of early Flexport employees joining [The SaaS News, March 2026].
Tenkara sells what Stern calls an AI operations and supply chain platform for manufacturers, with the wedge being supplier sourcing: helping a plant manager find qualified vendors faster and flag the conditions that typically precede a delay [Tenkara website, retrieved 2026]. The pitch is narrow and concrete. Rather than a horizontal procurement suite aimed at Fortune 500 indirect spend, Tenkara is going after the operators who actually pour, mold, machine, or assemble physical goods in the United States, a customer base that has historically been served by a mix of spreadsheets, ERP add-ons, and trade data tools like ImportYeti.
The bet
The company frames itself as building "ops agents" for US manufacturers, software that does work rather than just surfaces dashboards [PR Newswire, March 2026]. That framing matters. The previous generation of supply chain SaaS asked buyers to enter data and read reports. The agent framing promises that the software will draft the RFQ, screen the supplier, chase the quote, and escalate the exception. Whether Tenkara delivers on that ambition end to end is the open question of the seed stage, but the wedge it has chosen, sourcing, is the workflow where manufacturers feel the most acute pain and where an agent's output is easiest to verify against a human baseline.
Stern's own factory is a useful proof point for the design partner motion. A founder who runs a real plant has a built-in laboratory to test whether an agent's supplier shortlist is any good, and a credible voice when selling to peers who have heard plenty of pitches from people who have never sat through a quality audit.
Why the timing could work
US manufacturing has been the subject of a sustained policy and capital push, from CHIPS Act fabs to reshored contract manufacturing for medical devices and consumer goods. The operators staffing those facilities are, for the most part, not running modern software. True Ventures, which led the round, has a long history backing developer and operator tools, and the syndicate of HF0, WndrCo, and the Flexport alumni group reads as a deliberate bet on someone who has actually shipped physical product [The SaaS News, March 2026]. HF0 in particular is known for backing technical founders building from scratch, which fits a solo founder writing the first version of a vertical agent product.
The upside case, if Tenkara executes, is becoming the system of action for mid-market US factories: the place where a sourcing manager starts the day, the layer that talks to the ERP, and eventually the connective tissue across procurement, quality, and production planning. That is a large prize, and it is one that incumbents have not captured because their products were designed for a different era of buyer.
Funding snapshot
| Round | Date | Amount | Lead |
|---|---|---|---|
| Seed | March 2026 | $7,000,000 | True Ventures |
Additional participants in the seed included HF0, WndrCo, Articulate Capital, Night Capital, SF1, Transpose, and early employees of Flexport [The SaaS News, March 2026].
The founder
Stern's biography is unusual for a supply chain software founder. He started Nohbo, an eco-friendly personal care company, while in high school and closed a deal with Mark Cuban on Shark Tank in 2016 [Forbes, March 2016]. He was named a Thiel Fellow in 2020 [PR Newswire, March 2026]. Through Nohbo he has spent the years since operating a 15,000 square foot manufacturing facility, the kind of hands-on production experience that most enterprise software founders do not have [MaaterMakers, retrieved 2026]. Tenkara is being built as a solo founder company at the seed stage, and the early job postings include an integration engineer role, suggesting the next hires will focus on connecting Tenkara into the ERPs and data sources that manufacturers already run [Jobright.ai].
What the bears say, and the bulls' answer
The most credible concern is competitive. Sourcing intelligence is a crowded category, with ImportYeti and a long tail of trade data and procurement tools already serving overlapping use cases [Reddit, r/SupplyChainLogistics]. A Reddit thread on Tenkara surfaced exactly that comparison from a practitioner. The bull answer is that ImportYeti and similar tools are primarily databases, while Tenkara is positioning as an agent that performs the sourcing workflow rather than just exposing the underlying records. If Stern can show that an agent reduces the time from "we need a new supplier for component X" to a vetted, quoted shortlist, the comparison stops being apples to apples. That is a deliverable the company will have to demonstrate with named customers, not just describe.
What to watch in the next twelve months
Three milestones will signal whether Tenkara is converting its seed round into something durable. First, named design partners or case studies on the customers page, which today is positioned as a placeholder for real-world factory stories [Tenkara customers page, retrieved 2026]. Second, the shape of the early team: an integration engineer hire suggests ERP connectors are coming, and the breadth of those integrations will determine how quickly Tenkara can land mid-market accounts. Third, an A round timeline. A $7 million seed from True Ventures buys roughly eighteen to twenty-four months of runway for a small team, and the next raise will be priced on whether the agent framing has produced measurable workflow displacement inside real factories.
For now, Tenkara is one of the more grounded entrants in the vertical AI agent wave: a founder who knows the customer because he is the customer, a focused wedge in sourcing, and a syndicate that has seen this category before. The work ahead is to prove the agent does what the deck says it does, on the floor, on a Tuesday, when a shipment is late.
