🧪 LeadSafe
Bangladesh's mass childhood lead poisoning is detectable, costly, and demonstrably fixable
How LeadSafe closes the loop
Sample → Screen & test → Result & advice → Lead removed → Healthier children
An invisible lead-poisoning epidemic
The harm is slow — lost IQ, not sudden death — so it goes unseen. The cure is known (cheap detection + public pressure + enforcement); what's missing is a way to deliver it continuously and self-fundingly, not as one-off NGO campaigns. Sources: informal used-battery recycling (~1,100 sites), turmeric adulterated with lead chromate, lead paint, e-waste, and aluminium/ceramic cookware.
Local testing agents + a trusted mark
Each agent carries a portable XRF analyser and tests spices, cookware, paint and toys. Traders, mills, exporters and brands buy a consumer-trusted "Lead-Safe" certification mark — so the people who need clean supply chains to sell are the ones who fund the testing. The platform owns the device fleet and runs the registry, QA and training; the agent needs no capital and earns a livable wage.
The device is the cost — so B2G + B2B carry it
One unit = 1 XRF analyser + 1 trained agent. The XRF is ~56% of monthly cost, which is exactly why no consumer-fee model alone can carry it. Revenue, proven-base → upside: a B2G anchor contract (BFSA / National Action Plan / city corporation, the budgeted enforcement work) ≈ BDT 80k/mo is the base; B2B certification ≈ BDT 4k/mo per client; consumer per-test fees are upside (unproven).
How it makes money — and what it needs to close
Needs one signed B2G/B2B anchor (BFSA · National Action Plan; Pure Earth as testing partner). The moat is the certified mark + registry, not selling tests — cheap Daraz swabs already commoditised those. One agency funding testing proves it.
B2G enforcement (BFSA/NAP)
B2G enforcement → · B2B/export certification + the mark · blood screening · (consumer = upside)
B2G anchor + B2B certification
govt gets a paid enforcement arm; exporters/brands get a credible clean-mark
−2k at 8 clients; break-even ~8.5 with anchor (consumer excl.)

Bangladesh's mass childhood lead poisoning is detectable, costly, and demonstrably fixable
Turmeric lead cut 47%→0% (Stanford); XRF trusted by US CPSC
35.5M children poisoned · ~3.6% of GDP lost
The situation in Bangladesh
In Bangladesh an estimated 35.5 million children carry blood lead levels at or above 5 µg/dL, the threshold for action, making the country the fourth most-affected in the world by number of children poisoned 1. The damage is not abstract: lead exposure costs an estimated 20 million IQ points lost each year, valued at roughly USD 10.9 billion, on the order of 3.6% of GDP 1. The poison hides in everyday life, flowing from more than 1,100 informal used-lead-acid-battery recycling sites, lead-adulterated turmeric and spices, contaminated cookware and paint 1. Paint alone shows how porous enforcement is: despite a national 90 ppm limit set in 2018, a 2026 study found 42% of sampled paints exceeded it and 26.2% topped 1,000 ppm, with only 21.6% properly labeled 3, and the gaps cluster among smaller and informal producers where regulation reaches least 3.
Our pitch
LeadSafe does not sell tests; it sells trust — deploying local testing agents armed with handheld XRF analyzers, the same field technology the US Consumer Product Safety Commission relies on to screen consumer goods to within roughly 0.5% accuracy, to verify products and award a 'Lead-Safe' certification mark traders and brands can display 4. The wedge is proven: the Stanford-led turmeric intervention combined rapid lead detection with food-safety enforcement and education and drove adulterated market samples from 47% in 2019 to 0% in 2021, cutting tested blood lead levels a median 30% within 16 months 2. That same playbook generalizes, because Pure Earth's screening across 25 low- and middle-income countries found lead in cookware, foodware, cosmetics, spices and toys — a broad and certifiable market beyond any single product 5. By making 'tested clean' a visible, sellable asset, LeadSafe aligns commercial incentive with the public-health goal rather than fighting it, closing the enforcement gap that leaves informal producers untouched 3. It is not a silver bullet — certification works only where buyers reward it — but in a market already stung by turmeric and paint scandals, demonstrated safety is becoming something worth paying for 1.
Built so the operator never fails
HelperChain doesn't hand out a loan and walk away. Every operator gets the full rail — inputs, training, finance, supervision, and a guaranteed buy-back of what they produce. We carry the risk so an ordinary person can succeed.
The tools, inputs and hands-on training to start — turning sample into a working operation. No prior capital or expertise required.
Pay-as-you-go, riba-free finance makes a poor person a funded operator — with no debt if a cycle fails. The network carries the downside, not the operator.
Ongoing follow-up and quality assurance — the factor peer-reviewed evidence shows decides whether ventures survive (p<0.001). The operator is never left alone.
We commit to purchase the output at a fair, pre-agreed price — so there is always a market. The operator just produces; we guarantee the offtake. This is what removes the fear of failure.
A thin margin funds the next operator — so help compounds and the network grows stronger with every person it lifts.
