The principal-led accelerator
for founders building what’s next.
From pre-seed to Series A — operator-led, no committee, no consensus. Thirty years of building, breaking, and backing the companies that matter.
Space Tech Specialists
Space economy founders face challenges no generalist programme understands. We've been inside the sector for over a decade — as operators, investors, and board members. Our mentorship is sector-specific and direct.
Principal-Led, Not Committee-Driven
Decisions come from DMH directly — not a fund committee or a junior associate. You get the person who has sat on both sides of the table, made the hard calls, and been accountable for the outcome.
Operator Network & Connections
Access a 30-year network of decision-makers, co-investors, and commercial partners across the UK, US, Europe, and Monaco. We open doors that most accelerators can only promise.
Investment Ready from Day One
Every element of the programme is designed to get you investor-ready — pitch sharpening, data room, financial model, narrative. By the end you'll know exactly what the next room of investors needs to hear.
Ongoing Portfolio Support
We don't disappear at demo day. Portfolio founders get continued access to DMH, board-level guidance, and the STV network at every stage from seed through to exit.
Global Reach, Grounded Advice
Space is a global economy. Our programme spans UK, US, and European markets, with particular depth in Monaco and the UHNW capital networks that don't show up on LinkedIn.
We came in with a technology and left with a business. DMH understood our value proposition faster than we did — and helped us communicate it to investors in a way that landed. We closed our seed round within 90 days of completing the programme.
Most accelerators give you workshops. STV gave us a principal who'd actually done it. Thirty years of hard-won operator knowledge in the room with you is worth more than any curriculum. Blunt, honest, and exactly what we needed.
The network alone was worth it. Introductions that would have taken us two years of conference-going happened in the first three weeks. DMH opened doors we didn't even know existed.
I've been through two other accelerators. This is different. You get the person, not the programme. DMH tells you the truth — not what you want to hear. That's rare and it's what every founder actually needs.
Three phases. Twelve weeks.
One goal: get you ready.
Orientation — meet the network, set the baseline, establish goals
Validation — test your assumptions; workshops on investor expectations
Narrative — reshape your story; proposition clarity and market framing
First Pitch — present to DMH and network for unfiltered feedback
Commercial Strategy — GTM, pricing, revenue architecture
Midpoint Review — progress evaluation; adjust the plan
Fundraise Prep — data room, financial model, investor materials
Network Sprint — deep introductions to investors and partners
Pitch Intensive — daily practice, investor Q&A simulation
US Market — events, investor meetings, commercial introductions
Europe & Monaco — UHNW network, European VC and family office access
Demo & Close — final showcase; STV portfolio activation
The window is open now
Private capital is moving faster than governments. SpaceX proved it. The next decade will create more space-economy wealth than the last fifty years combined. We intend to be in the room.
This is a rollercoaster.
We’ve been on it.
We’re still buying tickets.
Building a company in the space economy is not like building a SaaS tool. The timelines are longer, the complexity is higher, and the capital requirements are brutal. We know because we’ve navigated it — as operators, as investors, and as the person sitting across from the founder at the hardest moment. If you know this is going to be hard and you’re building anyway, we want to talk.
Four steps. No committees.
