letni is the control room for your pyrolysis plant — feedstock, reactor runs, yields and margins in one place. So you're running the plant, not chasing it.
One operator can tell you his cost per litre of pyrolysis oil to the penny, which batch under-yielded last Tuesday, and exactly when the condenser is due for service. The other is running on gut feel and a spreadsheet that went stale three runs ago.
Same equipment. Completely different business.
The plant is telling you something every hour it runs. letni is where you finally hear it.
Most pyrolysis operators run production on a whiteboard, feedstock on a notepad, and financials in a separate spreadsheet nobody reconciles until month-end. letni puts all three in one place, so a batch you log on the reactor floor shows up as inventory, yield, and revenue without anyone re-typing it.
Know what you're feeding it. Log every tonne — source, moisture, type, cost. When yields move, you'll know whether it was the reactor or the raw material.
Every batch on the record. Temperature profile, residence time, operator notes, start to shutdown. No more "I think that run went long." You'll have the number.
Oil, char and syngas — per batch and per tonne. See which feedstock actually pays and which one's been quietly costing you. The split that used to live in someone's head now lives on one screen.
Cost in, product out, money made. Your real number, updated as the plant runs — not a figure you reconstruct at month-end and half-trust.
The condenser doesn't care that you're busy. Service schedules that chase you before a part fails, not after. Downtime you planned beats downtime that planned you.
Every run logged, every figure exportable. When the auditor, the buyer or the investor asks for the numbers, you send them in a click instead of a week.
letni ties every kilogram of tyres in to the oil, carbon black, and steel that comes out. When a batch's yield looks off, the floor knows immediately — not at month-end, buried in a spreadsheet.
It works — until the operator who holds it all in his head takes a day off, or you try to prove your unit economics to someone writing a cheque.
letni turns how your plant runs into something you can see, hand over, and improve.
One reactor running blind for a week can cost you more than a year of letni. This isn't the expensive part of your operation — not knowing your numbers is.
Plus $129/mo per additional plant. Every feature included, unlimited team members.
For multi-site operations that need rollups across sites and SSO.
Prices shown for the US, Germany, and most countries. Lower regional pricing is available for India, Southeast Asia, and Eastern Europe — you'll see your rate at signup.
letni is pyrolysis plant management software for tyre pyrolysis operations. It tracks batch mass balance (tyres in, oil, carbon black and steel out), inventory and storage, financials, and reporting in one system, instead of spreadsheets and whiteboards.
The Professional plan is $299/month and covers your first plant, plus $129/month for each additional plant — team members are always unlimited and free. Operations running multiple sites can move to the Enterprise plan (from $899/month) for cross-site rollups and SSO.
Yes. Every plan starts with a 30-day free trial, and you can cancel anytime before it converts to a paid subscription.
Yes. Pricing is lower for teams in India, Southeast Asia, and Eastern Europe — you'll see your rate automatically at signup based on your location.
Yes. Plants can be grouped under shared sites so inventory and reporting roll up across your whole operation. Cross-site rollups and SSO are part of the Enterprise plan.
Each batch records feedstock (tyres) in, and pyrolysis oil, carbon black, and steel out. Yield is calculated automatically, and a batch is flagged if its yield looks off compared to what's expected.
Owners and operators running pyrolysis facilities who need production, inventory, and financials in one place — with role-based access so operators can log batches and owners can review them before they hit the books.
The reactor's built. The feedstock's coming in. The only thing missing is a clear line of sight from what goes in to what you actually made — that's the whole job of letni.
