Liquid-nitrogen backup of elite clonal plant lines for tissue-culture labs
TL;DR Frostkeep stores frozen backup copies of the plant lines that tissue-culture labs, breeders and herbal-extract firms multiply from. If a line is lost to contamination, virus or a power cut, the client gets it back. Clients pay a yearly fee per line. It might work because those lines cannot be stored as seed.
Banana, potato, ginger, turmeric, vanilla, many fruit rootstocks and most medicinal clones grow from cuttings or cultures, not seed. So a private lab's best line exists only as living plants or jars on a shelf. One bacterial contamination, a virus outbreak or a growth room that fails overnight can wipe out years of selection, and nobody gets those years back. Viruses are common in clonal stock too - one study found a citrus virus in 76% of sampled Kinnow plants[1].
The national genebank at ICAR-NBPGR holds about 43,700 in vitro cultures, but only 347 accessions sit in its cryo base collection, and that material generally isn't handed out[2]. It's a national conservation store, which is great, but it is not a backup service a private company can call on.
Regulatory scope: storage of a client's own plant material as a custodian. Frostkeep does not own, breed or sell the lines it stores. Commercial use of biological resources falls under the Biological Diversity Act as amended in 2023, so ownership and origin are recorded for every deposit[3].
Here's how it works. Clients send shoot tips or cultures of each line. Frostkeep runs a species-specific freezing protocol and stores the tips in liquid nitrogen at −196 °C, the method the national cryogenebank uses[2]. NBPGR's own guideline is at least 150 shoot tips per line to reach 40% regrowth[2]. A sample from every deposit is thawed and regrown to prove it works, and the client gets a viability report. On request, Frostkeep thaws and returns plantlets.
The seed proposed farmer-run cryobanks plus AI seed advice. Ordinary seeds already store well in cold rooms, and liquid nitrogen needs a trained lab, so I kept only the part with a clear gap - clonal lines.
Who signs the cheque? Commercial tissue-culture labs, private breeders of clonal crops, and herbal and flavour companies that lean on one high-yield clone. The payer is the founder or R&D head, and what they're buying is insurance for their most valuable lines. I couldn't find a public price for private plant cryostorage in India. So your first job is to learn what a lab thinks one line is worth.
A 2026 review describes shoot-tip cryopreservation as the only reliable long-term method for clonal crops and for elite in vitro clones used by the pharma, food and cosmetic industries[4]. India's cryogenebank has 30 years of protocols and shows seed viability after 25–30 years in storage[5]. The 2023 amendment also replaced criminal penalties with fines, which makes compliance clearer for small firms[3].
There's no public figure for private germplasm storage in India. The narrow signal is the gap - the public in vitro genebank holds 2,038 accessions, yet only 347 have reached cryostorage after decades of work[2]. That shows the method works and that capacity is scarce. How many private labs would pay is unknown.
ICAR-NBPGR runs India's in vitro and cryo genebanks and has supplied over 1,500 accessions under material transfer agreements[2], but it serves national conservation and not private backups. I found no Indian private company offering cryo backup of plant lines. Large seed companies may run their own freezers. The gap is the small and mid-size lab with no backup at all.
| Difficulty | Moderate (50/100) |
| Starting capital | ₹1.2–2.2 Cr |
| Time to launch | 12–18 months |
Every species needs its own freezing protocol, and some respond badly to the chemicals used[4]. You need cryobiologists, a reliable liquid nitrogen supply and power backup. Sales will be slow because labs have to trust you with their most valuable material, often for years, and trust like that does not come from a brochure.
Yes. Storing biological material for commercial clients brings in biodiversity law.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI decide whether a line is viable. Only the thaw-and-regrow test proves that.

I like this for a cryobiologist with genebank experience and the patience for a slow sale built on trust. As a standalone venture-scale company it's a poor fit, honestly. Start as a service line inside an existing tissue-culture lab and prove one thing - that ten clients will pay a yearly fee per line.
Plan for roughly ₹1.2–2.2 Cr for the lab, storage tanks and early operating costs.
You need to notify your State Biodiversity Board before commercial use under the Biological Diversity Act, plus written custody agreements with clients.
Yes. Check the local biodiversity and material transfer rules before you accept deposits. My advice is to run a small paid pilot with a few real customers before you commit the full budget.
The free Frostkeep validation kit has the line-by-line capital breakdown, the effort scoring, the biodiversity-law checklist, a 14-day validation sprint with pass/fail targets, a 90-day launch plan, 10 interview questions for labs and breeders, and 5 assumptions to test. Download the kit →
Thinking about building Frostkeep or something close to it? The make-or-break work is proving reliable regrowth across species before you ask labs to trust you, and that's the kind of plan I help founders put together. If you need a hand, you know where to find me. Talk to Yash →
