# Jacaranda Labs > Seven software ventures built by one operator and a set of agents, and the publications that study them. Harare, Zimbabwe. ## Sections - [Laboratories](https://jacaranda-labs.pages.dev/): the seven ventures - [Portfolio](https://jacaranda-labs.pages.dev/courage-garikai/): Courage Garikai, Autonomous Cognitive Infrastructure Engineer, Operator and Writer - [Publications](https://jacaranda-labs.pages.dev/publications/): 20 works, 10 readable free - [About](https://jacaranda-labs.pages.dev/about/): ownership and disclosure ## Ventures - [AttestOS](https://attestos-edge.attestos.workers.dev/): Bot checks your visitors never see. An invisible proof-of-work check with a server-side verify call, in place of CAPTCHA puzzles. - [TightBucket](https://0x.tightbucket.workers.dev/): Website leak audits. Twenty-second audits that show where a website loses revenue, with the evidence and the fix, for stores, SaaS, sales teams and agencies. - [DeskOS](https://deskos.deskos.workers.dev/): Working desks for customs, safari and tender firms. Web desks with working calculators for customs and freight, safari and DMC, and tender and donor ESG firms, with daily open notices for tender firms from 13 public sources (World Bank, UN agencies, EU TED and national portals), by region. - [STPi](https://getstpi.pages.dev/): Strategic Talent Placement Infrastructure. Hunts public job ads across African markets, drafts a cover letter and tailored CV for each, and waits for a person to approve before anything is sent. - [Tapstall](https://tapstall.zlnew.workers.dev/): A shop link for the markets the big platforms skip. A storefront link for informal and social-commerce shops that understands EcoCash, InnBucks and PayShap and matches exact payment amounts. - [Open Practice](https://open-practice.zlnew.workers.dev/): Practical AI, learned by doing. A learning platform where people practise with AI tools on real tasks, using their own free API keys, and keep what they make. - [Mechanism Audit](https://mechanism-audit.whop.site/): The product audit that reads the evidence. A five-day written audit of what a product actually does: the claim on the page, the mechanism behind it, and the gap in writing. Three priced products — the audit, a self-check pack and a fix sprint — sold through the store. ## Publications ### Books - [Emotional Engineering for AI-Oriented Infrastructure Operators](https://jacaranda-labs.pages.dev/publications/emotional-engineering/): Trust, agency and ethical adoption in systems that act (private author-review, request a copy) - [The Tight Bucket](https://jacaranda-labs.pages.dev/publications/tight-bucket/): Designing constraint-native digital businesses (private author-review, request a copy) - [Proof of Mechanism](https://jacaranda-labs.pages.dev/publications/proof-of-mechanism/): How leaders who build with AI agents tell a working product from a convincing demo (private author-review, request a copy) - [Nobody Was Watching](https://jacaranda-labs.pages.dev/publications/nobody-was-watching/): How founders run autonomous growth systems without harming strangers, their brand or themselves (private author-review, request a copy) - [Flower and Bees](https://jacaranda-labs.pages.dev/publications/flower-and-bees/): The Jacaranda voice guide: how every page, product and message should feel (private author-review, request a copy) ### Working papers - [Constraint-Native Business Model Design](https://jacaranda-labs.pages.dev/publications/constraint-native-business-models/): Quota-bounded autonomy, proof-first acquisition and verification debt in a zero-cash, AI-built venture (private author-review, request a copy) - [Simulated Completeness](https://jacaranda-labs.pages.dev/publications/simulated-completeness/): Claim–mechanism gaps, mechanism audits and the rebuild decision in an AI-era trust product (private author-review, request a copy) - [Unwitnessed Autonomy](https://jacaranda-labs.pages.dev/publications/unwitnessed-autonomy/): Externalities, borrowed identities and duplicate clocks in an autonomous growth pipeline (private author-review, request a copy) - [The Sovereign Micro-Enterprise](https://jacaranda-labs.pages.dev/publications/sovereign-micro-enterprise/): A Governance-First Architecture for Zero-Capital Agentic Businesses (free to read) ### Published editions - [The Ledger and the Shopkeeper](https://jacaranda-labs.pages.dev/publications/ledger/): Building commerce for the markets the platforms forgot (free to read) - [Intelligence, Data and Judgement](https://jacaranda-labs.pages.dev/publications/intelligence/): An applied introduction to artificial intelligence, with a production case (free to read) - [Order Without Custody](https://jacaranda-labs.pages.dev/publications/custody/): Governance-first design for merchant commerce rails in low-infrastructure economies (free to read) - [Grounded Cadence](https://jacaranda-labs.pages.dev/publications/cadence/): Fact-bound content operations as a governance architecture (free to read) ### Trade books and essays - [The Musk Mirror](https://jacaranda-labs.pages.dev/publications/musk-mirror/): How one billionaire exposed the cracks in China's innovation dream (free to read) - [Traffic Is the New Oil](https://jacaranda-labs.pages.dev/publications/traffic/): The African digital wealth formula (free to read) - [Pinterest Goldmine](https://jacaranda-labs.pages.dev/publications/pinterest/): The traffic source nobody told you about (free to read) - [The Rocket Man Reckoning](https://jacaranda-labs.pages.dev/publications/rocket-man/): How China mocked Elon Musk — and why they are now panicking (free to read) - [Unchained Blueprint](https://jacaranda-labs.pages.dev/publications/unchained/): What to build when every payment door is closed (free to read) ### Earlier works - [The Governable Enterprise](https://jacaranda-labs.pages.dev/publications/governable/): A practical guide to evidence, authority and AI operations — lessons from DeskOS (listed for the record) - [From Spreadsheet Interface to Governable Autonomy](https://jacaranda-labs.pages.dev/publications/autonomy/): DeskOS as a critical design-science case of evidence, agency and resource-constrained AI infrastructure (listed for the record) ## Notes - Contact: couragegarikai@atomicmail.io - Jacaranda Labs owns the ventures below and funds the publications through the Jacaranda Labs AI Think Tank.
