Licensing, prices and payment in plain answers.
What does Delithius Labs license?
Delithius Labs LLC licenses three product lines online at public prices: Northgate (the Northgate Developer License and the Tier I Sovereign Stack License), the QC Fix Engine (embed it in your product, or run it for your clients and resell it) and LagZero (creator and platform licenses). Every license is licensed, not sold, under an agreement published in full on this site.
How much does a Delithius Labs license cost?
Help prices for individuals and growing companies: Northgate Developer License $500, QC Fix Engine licenses $2,500, LagZero Platform License $2,500 one-time plus a 5% running royalty, Tier I Sovereign Stack $15,000. Full prices: Northgate Developer License $2,500, QC Fix Engine licenses $25,000, LagZero Platform License $25,000 a year, Tier I Sovereign Stack $150,000. Each tier also carries the running royalty shown on its card and in its agreement.
How do I buy a license?
Pick a tier, read the full License Agreement on the order page, accept it and pay in full at Stripe Checkout by card or U.S. bank account (ACH). Your license key and API key issue the moment payment clears.
What is the difference between the help price and the full price?
The help price is for individuals and growing companies: annual revenue under $10,000,000, under 250 employees and under $50,000,000 in outside funding, privately held and non-governmental. The full price is for established companies, listed companies and government. You certify your price tier at checkout.
Can I read the agreement before I pay?
Yes. The full License Agreement for your tier opens on the order page and stays published at a stable address to save or print. You accept it with a checkbox and your typed name before checkout.
Which law governs the agreements?
North Carolina law, with venue in the state courts of Wayne County, North Carolina, or the U.S. District Court for the Eastern District of North Carolina (Section 15.1 of each agreement).
What do I receive when payment clears?
A license for the United States for the term of your tier: one year for Northgate, the QC Fix Engine and the LagZero help price ($2,500 paid once), and one contract year renewing each year for the LagZero full price. Every tier adds one revocable license key and API key, a live key check, and your licensee portal with your accepted agreement, receipt and quarterly royalty reports. QC Fix Engine and LagZero licenses add use of the live engine; Northgate technical files are added to the portal as each release ships.
Which payment methods are accepted?
Stripe Checkout takes card or U.S. bank account (ACH). Every license fee is paid in full, up front.
