Ventures and operations

JDC Ventures is in formation: a home for engineering-led products and businesses. Jollymart provided the practical foundation in suppliers, launches, advertising and accounts.

CEO & Founder

JDC Ventures · in formation · Frimley

Establishing a home for engineering-led projects and businesses, bringing mechanical design, software, visualisation and commercial operations into one end-to-end approach.

One of my projects is EcoLayerLabs ↗, developing an additive-manufacturing operation.

  • Developing a portfolio of products and ventures: define a real problem, build a testable solution and refine it against practical and commercial constraints.
  • The focus spans physical products, digital tools and new commercial ventures, with design, delivery and operations considered together.

Business Operations Manager

Jollymart Ltd · Frimley

Ran operations for a UK-registered limited company from age 15: wholesale sourcing, a private-label product launch and day-to-day management across Amazon, eBay and a self-built website.

  • Owned a private-label launch end to end: negotiated price, minimum order quantity and specification directly with manufacturers, then validated supplier quality before committing to a bulk order.
  • Designed private-label packaging and compliance: custom tamper-seal branding, Amazon FBA barcode labelling and an in-pack QR code prompting reviews.
  • Led go-to-market and produced all creative in Blender, including a CGI spot used for a paid TikTok ad.
  • Created JollySip and JollySwipe’s naming, Amazon listing copy and complete product image sets. Each listing’s visuals took one to two weeks of Blender modelling and rendering, then Canva typography and layout.
  • Ran Amazon advertising and diagnosed the launch’s real loss drivers: ad spend outpacing margin, competitive underpricing and a supplier defect rate.
  • Owned bookkeeping and accountant liaison, preparing financial records for statutory filings. Redesigned the reporting format in 2026; the accountant adopted it as the standard going forward.
  • Built the company’s original website manually in Brizy.

Jollymart product listings

I turned two private-label products into complete Amazon listings—from premium names and copy to every rendered product image.

JollySip and JollySwipe were built as full commercial presentations, not supplier-image reskins. I named and positioned each product, modelled and rendered the image sets in Blender over one to two weeks per listing, then finished the typography and layouts in Canva. The wider launch covered suppliers, packaging, FBA compliance, advertising and the unit economics behind the result.

Alongside developing JDC Ventures, I’m applying for 2027 entry to mechanical and aerospace engineering degree apprenticeships. I’m open to relevant placements, insight days and conversations about products, prototypes and early-stage ventures.
