The errors worth fixing first are an unclear commercial problem, no named operator buyer, and no sign the hardware has worked in real marine conditions. Fix those before you send. A 2015 DocSend study, done with Harvard Business School professor Tom Eisenmann, looked at more than 200 general startup decks from companies that had raised $360 million in total. VCs spent an average of 3 minutes, 44 seconds per deck, as reported by TechCrunch. The study was not about ocean tech and is more than a decade old, so treat it as a rough guide. Still, a short first read is a good reason to make each point clear to a non-specialist at a glance.
The deck mistakes that lose ocean tech investors
An unclear commercial problem. A deck that opens with the technology (the sensor, the hull coating, the data pipeline) leaves out what the investor needs first: what the problem costs someone today. If you can't say it in a sentence with a number or a consequence attached, the rest of the deck has nothing to stand on.
No named operator. Say who runs the vessel, dock or facility, and why they would change a routine they have followed for years. "The maritime industry" is not a buyer. A harbor pilot association, a charter fleet or a survey contractor is.
Consumer-app framing. If your deck describes a hull sensor or a survey vessel the way it would describe a phone app, investors will assume you haven't talked to a buyer. Sales cycles in marine work are long, and hardware has to be installed, maintained and trusted. Growth charts borrowed from software decks work against you here.
Missing market sizing. Investors want to know how big the opportunity is, and in marine tech a top-down number for "the ocean economy" doesn't help. Size it from the operators you can reach: how many of them, what they would pay, and what you would need to deliver to win the first group. As an illustration, if you sell to charter fleets, count the fleets in your first region, multiply by what one fleet would pay per vessel and how many vessels it runs, and show where each number came from.
Pitching the wrong audience for the wrong thing. An early-stage fund cannot lead a late round, and a private equity firm will want an established business. Check a fund's range before you send anything.
Burying the three points that matter. Plan the first three slides so a generalist who has never seen a marina can follow the operator problem. If they can't, the later slides may not get a fair read. In order:
- The problem and its cost. What the problem costs a specific kind of operator today.
- Your edge and your buyer. Why your technology changes that operator's routine, and who the named operator is.
- The market. The reachable operators you counted, and what each would pay.
Put field evidence directly after those three, so the reader moves from claim to proof without hunting for it.
What investors expect from field testing and operator trust
Hardware-heavy marine ventures get judged on what happened on the water. Investors want evidence that the product survived real marine conditions: salt, vibration, heat, biofouling, rough handling by a crew that has no interest in babysitting it. A lab result or a calm-day demo is a start, but it does not answer that question.
Put these in the deck:
- Where and how long you tested, and under what conditions, including what failed and what you changed.
- The operator who hosted the test, named if they allow it, or described precisely if they don't.
- What that operator did next: a repeat trial, a paid pilot, a letter of intent, an introduction to a peer. If an operator paid for a pilot, lead with that ahead of any logos from conversations.
- Any measured result in the operator's terms, such as hours saved, fuel burned or downtime avoided.
A pre-send checklist
Before you send, check the deck against these questions:
- Does slide one state a cost, not a technology?
- Is a buyer named, along with who signs off?
- Is there a field-test slide with conditions, duration and failures fixed?
- Is every market count tied to a source and a geography?
- Do the unit economics hold up against what real operators budget?
- Does the fund's stated range match your stage?

When in the funding sequence to send the deck
Send an investor deck once you have field evidence to put in it: the commercial problem defined, a field test on the record and at least one operator willing to be described. Until then, the earlier steps on the capital staircase, proof of concept (a working demonstration that the technology does what you claim) and non-dilutive awards (money that doesn't take equity), are where that evidence gets built. Once it exists, the deck is ready for investors, including at pre-seed. Ocean Exchange alone decides its Neptune and Collegiate awards, so read its published criteria for an application rather than assuming they match an investor's.
