Jack J.

Tech Startup Founder Available for AI, Startup and Growth Consulting

As a startup founder, I've run and closed three consecutive up-rounds of $340k, $881k, then another $881k, achieving a valuation at the last round of ~$22m. I closed a mixture of angels and early/seed-stage funds, pitching and closing 20+ individual investors. Every round was oversubscribed (by as much as $1m / £750k). I'm extremely fast: the two conventional equity rounds took 2 weeks to run, end to end. I know how to control the frame and negotiate: I remain a 70% shareholder, with sole, dictatorial control over the company and no board seats. "Jack has the highest close rate of any founder I've ever seen" — Shay O'Brien, founder, Bray Capital "Jack put so much pressure on me, I felt like I just had to take the meeting (and invest)" — Jens Lapinski, MD Techstars Berlin & founder, Angel Invest How I Can Help You Do the Same: While raising a round IS indeed a sales process, the difference between myself and a more sales-oriented consultant is that I can advise on every aspect of the process, and coach you play by play through the art of closing a real live round, once you're running it for real. I know EXACTLY what it takes to strategise and execute on every step of the capital raise process, and have done so multiple times. - Investor readiness : momentum, pitch decks, business modelling, product roadmaps - Investor network : outreach, networking, nurturing, activating - Deal planning: terms, instrumentation, sizing, etc. - Running real rounds: navigating real investor dynamics, getting commitments, signatures, and funds wired in time I've also raised six figures in non-dilutive government funding (HMRC R&D credits and an Innovate UK grant) and about $50k in alternative capital, so I can help you stack your war chest in more way than one. My Experience As founder and CEO of REMOJO I raised $2m, hit a ~$22m valuation, acquired 600k installs, a $600k annual revenue run-rate, global press coverage, and managed a team of 25+. Before that I built and sold my own ecommerce store, Rising Sun Prints. Earlier I was head of marketing and growth at various high-growth startups — I took one ecommerce business from $10k to $230k per month, and at ClassTag I built the entire marketing funnel end to end and helped take them from 200 to over 3 million users. I was also a marketing/branding copywriter back in the day here on Upwork; you can see my stack of 5★ reviews for those projects on my profile. It certainly helps with pitch decks, outreach and investor comms. I like to move projects forward as quickly and as intensely as possible, especially with fundraising. If you're raising a pre-seed or seed round and want someone who's actually done it, let's get it moving so you can get on with building your company.
