Start a conversationFrom breakthrough to business.
Four ways in, one commercial partner: everything on the business side that a growing agtech or climatech company needs, without hiring a full executive team to get it.
Strategy
The decisions that set a startup’s direction: which market to enter first, how to build the business, and a commercial plan your team can run.
Go-to-market & positioning
Who your customers are, what you promise them, and how you reach them: positioning, pricing, messaging and the materials that carry your message.
Business development
Partnerships and first sales. Finding the right counterparties, structuring the deal, and getting it closed.
Fundraising
Support for the rounds that take a company to its next stage: your narrative, your materials and your investor strategy.
Pitch and presentation: the deck, the narrative and how you deliver it.
Built for the way startups actually work.
Only your sector
Agtech and climatech, nothing else. Field trials, registries, long sales cycles and the corporate buyer who needs to see proof first are familiar ground.
An operator, not an observer
Dan has co-founded five ventures, most of them in agtech and climatech, one acquired so far. He has raised over $62M in venture funding for more than a dozen startups and has experienced over a dozen exits as an angel investor. The advice comes from having done it.
Scoped to fit
Engage me for a defined project or milestone, or as an ongoing monthly partner. Either way, the scope and the outcome are clear from the start.
