Native soil-microbe strains, screened and licensed to biofertiliser makers
TL;DR Soilwright collects microbes from Indian soils, tests which ones help crops in the lab, in pots and then in fields, and licenses the best strains to biofertiliser companies. Makers pay licence fees and royalties. It works without genetic engineering, which keeps it on a regulatory path a startup can afford.
India's biofertiliser market is small next to chemical fertiliser, at US$159.41 million in 2025 by one estimate[1]. Many products rely on a short list of well-known organisms, and companies differ mainly on formulation and price. And a farmer who tries a product that does nothing rarely buys it again, which is fair enough.
Better strains exist in Indian soils, adapted to local crops, salinity and heat, but finding them is slow lab work. Most makers are small and lack research teams. Public research institutes do isolate strains, yet the step from a paper to a product a company can sell is often missing. Even for fungal biocontrol agents, only some species have been registered[2].
What it does, in regulatory terms: discovery and licensing of naturally occurring, unmodified microbes. Products made from them are sold by licensed makers under India's fertiliser rules. Soilwright does not release genetically engineered organisms.
The seed proposed engineering microbes with AI, and I reframed it. In India, engineered micro-organisms fall under the Rules 1989 for genetically engineered organisms, a multi-authority approval process[3] that can take years before a field release. A US startup has shown gene-edited nitrogen microbes can sell in the US[4], but that path is not open to an Indian startup on seed money.
Soilwright samples soils across crop zones and isolates thousands of strains. It sequences the genomes of promising ones and runs fast lab assays for traits such as phosphate solubilising or tolerance to salt. A model trained on the genome and assay results ranks which strains to move into pot trials, then multi-season field trials with partner farms. Winning strains go to makers with trial data, a reference culture and formulation advice.
Farmers use the end product but pay the maker, not Soilwright. The buyers are biofertiliser companies, cooperatives and agri-input firms wanting a differentiated product. My assumption is an upfront licence of ₹10–40 lakh per strain and crop, plus a royalty of 3–6% of product sales. Contract screening for larger firms is a second income line.
The market is expected to grow at 11.04% a year to US$443.79 million by 2034[1]. Large players are moving too - a national fertiliser co-operative launched a mycorrhizal product with a global enzyme maker, and one Indian biologicals startup has started exporting[1]. Biostimulants came under fertiliser rules in 2021[5], showing the government now formally regulates biological inputs, which favours makers with real trial data.
IMARC puts India's biofertiliser market at US$159.41 million in 2025 (about ₹1,540 Cr)[1]. Soilwright earns a slice of that through royalties, so the reachable revenue is a few per cent of the market. I found no public figure for strain-licensing deals in India. Count how many makers would pay for a new strain before raising money.
One US startup sells engineered nitrogen-fixing microbes for corn and wheat[4]. In India, established biologicals makers, a national co-operative and newer startups sell biofertilisers and some run their own research[1]. Public institutes isolate and hold strains but rarely run commercial field programmes. The gap is an independent discovery lab that does the field proof and licenses to smaller makers who cannot afford research.

Lab screening is the easy part. Field results vary by season, soil and crop, so you need several seasons of trials before a maker will pay. A strain that shines in pots can fail in a farmer's field, and the model is only as good as the field data feeding it.
Your licensees need product approvals, and your strain choice decides which route applies.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust a model's ranking as proof a strain works. Only replicated field trials count, and buyers will ask for them.

Here's what can go south -
I think this fits a founder with a soil microbiology PhD and links to field research stations who can survive a long trial cycle. If you're expecting quick revenue then walk away. First prove one strain beats a market product in at least two seasons of multi-site trials, and that two makers will sign licence terms.
Plan for about ₹2–3.6 Cr, mostly lab equipment, sequencing and several seasons of field trials. The free kit has the line-by-line capital breakdown.
Your licensees register products under the Fertiliser Control Order. Unmodified strains avoid the GM approval route, and biodiversity rules need checking.
Yes, local strains suit local soils anywhere. Check your country's fertiliser, GM and biodiversity rules first.
The free Soilwright validation kit has the line-by-line capital breakdown, the effort scoring, the fertiliser, biosafety and biodiversity checklist, a 14-day validation sprint with pass/fail targets, a 90-day launch plan, 10 interview questions for biofertiliser makers, and 5 assumptions to test.

Thinking about building Soilwright or something close to it? The make-or-break work is multi-season field proof and licence terms that makers will honour. If you need a hand, you know where to find me. Talk to Yash →
