Chainvial
A cheap sensor tag and shared custody ledger for every biological sample in transit.
Chainvial sells a thin, disposable temperature-and-shock tag that goes inside sample and reagent shipments, plus a free reader app, and writes each handoff to a custody record both the sender and the receiver can see.

Test it before you build it
$900 · 4 weeks · 30 prospects
For $900 and four weeks, prove that labs will prepay $149 a box for verified shipment custody data that a free paper log supposedly already covers.
Riskiest assumption · A lab manager who ships biological samples will pay $149 from a real budget for verified condition and custody data even though the receiving lab accepts a free paper log today and nobody is penalised for a bad shipment.
1Focus group: who and where
The lab operations or shipping manager at a university core facility, biorepository, or 10-50 person CRO that sends at least five frozen sample shipments a month to central labs or sponsor sites, and who had a shipment questioned, delayed, or re-collected in the last quarter.
where to find 30 · ISBER's member community and online forum for biorepository managers; the CoreMarketplace and ABRF directories of university core facilities, filtered to biorepository and sample-processing cores; and r/labrats, where shipping failures are a recurring complaint thread and a direct line to the people who file them.
2Sell first, build later
A box of 20 disposable temperature-and-shock tags plus the shared custody record for every lab you ship to, first production boxes shipping November 14, 2026.
the ask · $149 per box of 20 tags, prepaid in full at checkout.
a real yes · A charged card for a box is a yes; a receiving lab confirming receipt inside the custody record is the second yes. 'This would be useful for audits', requests for free samples, and forwarded intros to procurement are not.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Bad-shipment penalty interviews
$250 · 10 days
Book 15 calls with shipping managers found through the ISBER forum and CoreMarketplace listings. Ask each for the last compromised or questioned shipment: what it cost in samples and rework, who paid for it, and what the receiving lab did with the paper log. One founder runs all calls off a fixed script and logs dollar figures in a sheet.
keep going if · 9 of 15 name a specific shipment in the past 6 months that cost over $2,000 in samples or rework, and at least 5 say their lab ate the cost
2. Prepaid box pre-order
$200 · 14 days
Put up a one-page site with the $149 box of 20 tags, the reader app, and a November 14 ship date, with full prepay at checkout. Drive the 30 outreach conversations and a post in the ISBER forum and r/labrats to it. No discounts, no free samples.
keep going if · 8 of 30 contacted labs prepay $149 for a box
3. Two-sided receiver test
$450 · 14 days
For 10 prepaid labs, include an off-the-shelf USB temperature logger (Elitech or LogTag) in their next real shipment and stand up a shared custody page per shipment, built by hand. Email the named contact at the receiving lab a link to view conditions and confirm receipt. Measure whether the receiver actually uses it.
keep going if · Receiving contacts on 6 of 10 shipments open the custody page and confirm receipt in it within 48 hours
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$149
per prospect, refundable
how · Full prepay of the first box through the checkout on the pre-order page - the right instrument for a self-serve buyer who already puts lab supplies on a card, no signature beyond the checkout terms. set up: Stripe Checkout ↗
what it reserves · A box of 20 tags in the first production run, the November 14 ship date, and reader-app accounts for the lab and every partner it ships to.
refund · Refunded in full within 5 business days if the buyer cancels before shipping or if the box misses the November 14 ship date.
target · 8 prepaid boxes from 30 conversations within 28 days
before taking money · Do not label or market the tag as a GxP-compliant or 21 CFR Part 11 record until a quality consultant reviews the claim; sell it as supplementary condition data alongside the receiver's existing log.
Go: build it if
8 of 30 labs prepay $149, and receivers on at least 6 of 10 instrumented shipments open and confirm the shared custody record within 48 hours.
Kill: stop if
Fewer than 3 prepaid boxes after 30 direct conversations, or fewer than 5 of 15 interviews surface a bad shipment that cost the shipping lab real money in the past year - then the operator judge is right and paper logs survive.
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
You ship frozen samples to central labs and the only condition record is a paper log taped inside the box. I'm building Chainvial, a disposable temperature and shock tag that rides inside the shipment and gives you and the receiving lab the same verified custody record. First production boxes ship November 14; a box of 20 tags is $149. Can I get 20 minutes this week to hear how your last questioned shipment got handled?
landing page
Know your samples arrived intact before the receiving lab opens the box $149 prepaid for a box of 20 tags plus the shared custody record both labs can see, shipping November 14, 2026 Prepay your first box - full refund any time before it ships
deposit terms
Your $149 prepays one box of 20 Chainvial tags and reader-app access for your lab and every lab you ship to. Boxes ship November 14, 2026; if we miss that date, or you cancel before shipping, you get a full refund within 5 business days. Your card is charged today and your lab is placed in the first production run.

The idea in full
- What
- Chainvial sells a thin, disposable temperature-and-shock tag that goes inside sample and reagent shipments, plus a free reader app, and writes each handoff to a custody record both the sender and the receiver can see. Sponsors, CROs, central labs and biomanufacturers buy tags online by the box with a card, no sales call. Value comes from the counterparty: once your lab is on the ledger, every partner you ship to gets verified condition data instead of a paper log.
- Why now
- Harbor (yc X26) is building an AI-native CRO for trial operations, AbInitio Bio (yc X26) an intelligence layer for drug manufacturing and 10x Science (yc W26) a protein characterization platform, all of which assume the physical sample arrived intact; of the 130 companies added to this cluster in two years, none instrument the shipment itself.
- Wedge: first customer and entry point
- Academic and small CRO labs shipping to a handful of central labs, sold self-serve at box prices, then pulled upward when a sponsor asks its vendors to ship on the same tag.
- Path to 100x
- Life science cold chain and sample logistics is a $10-100B market, and custody verification only works if both endpoints use the same ledger, which makes it winner-takes-most the way any two-sided proof standard is. Every new lab raises the value of the tag for all its shipping partners, and the ledger becomes the reference layer that GxP audits and trial monitors read.
- Ceiling
- Tags commoditise to a hardware margin and a large logistics incumbent bundles its own, leaving a real but sub-billion sensor business.
- Closest real companies, as the generator saw them
- Harbor (yc X26) and AbInitio Bio (yc X26) sit in trial and manufacturing operations software; 10x Science (yc W26) consumes samples downstream. None of them own the custody layer between organisations, which is what Chainvial is.
- Main risk
- Labs keep accepting paper temperature logs because nobody is penalised for a bad shipment, and the tag stays a nice-to-have.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
3/5
Self-serve two-sided proof standard with revenue in year one, but tags commoditize and a logistics incumbent can bundle its own.
Bootstrapper
3/5
Self-serve tags by the box sell within a year, but disposable hardware margins commoditise and nobody is penalised for a bad shipment.
Operator
2/5
Its own risk is decisive: nobody is penalised for a bad shipment, so a paper temperature log already satisfies the buyer.
Technologist
3/5
A disposable temperature-and-shock tag is real but shallow hardware that a logistics incumbent like the card's own ceiling case bundles away.
Risk
4/5
Self-serve box sales to a long tail of labs, revenue within a year, no licensing exposure, and no single platform can change terms on it.
trends
1/5
Absence of competitors among 130 new companies is not a why-now; disposable cold-chain tags were fully buildable and ignored in 2020.
