Ankit Gupta drafted the text for his engineering newsletter in the stray moments of his week: on subway rides, during lunch breaks, and late at night after his family went to sleep. Having spent a decade working in engineering and manufacturing, Gupta did not launch the project with an established reader base or a marketing team. Instead, when he created The Prepared, he opted to send his initial weekly dispatches to zero subscribers, resisting the temptation to mass-email his contact list. Over the next three and a half years, that solitary routine grew into a regular publishing rhythm that reached thousands of inboxes across the hardware industry.
Drafting in the Off-Hours
Before launching The Prepared, Ankit Gupta spent ten years working in engineering and manufacturing. When he decided to document the mechanics and economics of those fields, he added the project onto an already full schedule of full-time work, personal blogging, side projects, and giving half a dozen conference talks a year. Writing the newsletter demanded more time than any of his other side ventures, yet it operated without a commercial plan or corporate backing. Gupta fitted the research and writing into odd hours across his week, turning late evenings and commutes into structured technical analysis.
Starting at Zero
Rather than blasting his personal contact network to inflate his early metrics, Gupta sent his initial dispatches out to zero subscribers. This approach allowed him to refine his format, tone, and weekly cadence before an audience arrived. Once early readers began signing up organically, Gupta committed to a strict schedule: across three and a half years of operation, he never missed a single weekly issue. Over that span, The Prepared eventually delivered approximately a quarter of a million emails, establishing direct communication with readers across technical disciplines at a time when industry commentators predicted email would be replaced by workplace chat platforms.
Industry Analysis in the Inbox
Gupta grew his subscriber base by focusing his writing on lesser-known technical and manufacturing companies that rarely received mainstream media coverage. Rather than offering shallow link roundups or focusing solely on tech giants, he published detailed technical breakdowns that provided real analytical value to industry insiders. To deepen these connections, Gupta maintained an open policy with his audience: he offered to buy coffee for any reader who asked to meet in person. This open invitation routinely brought him into contact with practitioners, competitors, and potential collaborators, turning his weekly writing habit into a direct professional network.
From Weekly Writing to AI Discovery
The analytical discipline and network Gupta cultivated through The Prepared directly informed his work beyond publishing. He went on to co-found Reverie Labs, a company dedicated to developing machine learning models for drug discovery. His deep learning research led to published work at academic conferences such as ICML, bridging software engineering and biotechnology. In 2024, Ginkgo Bioworks acquired Reverie Labs.
Gupta's experience showed how consistent, detailed technical writing builds long-term industry leverage. By delivering a quarter of a million emails over three and a half years, he turned a zero-subscriber newsletter written in off-hours into an authoritative platform that shaped his trajectory as an engineering founder and researcher.
