Overwatch Technologies IPO: Raising A$8 Million to Build a Maritime Intelligence Business
Overwatch IPO: Overwatch Technologies is a 13-month-old Perth company that puts sensors on other people's drones and sells the intelligence that comes back. It has taken approximately A$1.88 million from government customers and holds a licence that carries no ongoing royalty; it has not recognised a dollar of revenue, and the sensing technology at its centre is licensed from a company founded by one of its own substantial shareholders. The offer closed on 18 September 2026, and a quotation is expected on 16 October.
Samso News | Defence Technology | ASX IPO Series | Samso Investment Strategy |
Two defence technology companies are listing on the ASX within four weeks of each other. Innovaero Technologies is scheduled for 22 September 2026, raising A$40 million. Overwatch Technologies Limited follows on 16 October 2026, raising A$8 million. Overwatch is the smaller of the two and the newer company by a wide margin.
The offer is already closed. Applications shut at 5 pm AWST on 18 September 2026, so this piece is not a chance to apply. It is a look at what is about to arrive on the board.
Overwatch has never been listed. There is no share price history, no record of how the company behaves under the continuous disclosure rules that apply to listed companies, and no market price to measure the offer against. The prospectus is a document the company wrote about itself, and it is the only substantial source available. Everything below comes from it [R1].
THE SOURCE DOCUMENT Overwatch Technologies Limited, Replacement Prospectus, dated 11 September 2026 and lodged with the Australian Securities and Investments Commission (ASIC). It replaces the original prospectus of 4 September 2026 in full, and the original can no longer be relied on. The terms of the offer are unchanged between the two. Available from the company at overwatchtechnologies.ai [R1]. |
The Offer - Overwatch Technologies IPO
The offer is 40,000,000 shares at A$0.20, raising A$8,000,000 before costs. Three features of it are unusual enough to read together (TABLE 01).
The minimum subscription is A$8,000,000, the same as the full raise. The minimum subscription is the floor below which a company will not proceed, so here the raise is all or nothing. If the full amount is not reached within three months of the original prospectus date, no shares are issued, and application money goes back [R1].
No oversubscriptions will be accepted, so the raise cannot grow beyond A$8 million.
The offer is not underwritten, which means no broker agreed to take up whatever the public did not. Euroz Hartleys and CPS Capital Group are joint lead managers, paid a 2 per cent management fee and a 4 per cent capital raising fee on funds raised, plus 5,000,000 options exercisable at 30 cents within three years. An option is the right, not the obligation, to buy a share at a set price by a set date [R1].

What Overwatch Technologies Actually Does
Overwatch does not build drones. The chairman, Harry Karelis, puts it plainly in his letter at the front of the prospectus, writing that “Overwatch is not a manufacturer of drones” [R1]. The company describes itself as a data aggregation business. It buys or licenses the best available parts, puts sensors on other people's drones, and sells the intelligence that comes out the other end.
The work is called ISR, which stands for intelligence, surveillance and reconnaissance. In plain terms, it is finding out what is happening across a large area and turning that into something a government agency can act on. Overwatch's current focus is detecting and tracking radio frequency emissions, the radio signals that vessels and equipment give off, across open ocean. That is how a boat which has switched off its tracking beacon can still be found. The chairman's letter names the targets as organised crime, narcotics trafficking, illegal fishing and dark fleets, meaning vessels running with their identification systems turned off.
The company sets out four steps. Sensors go up on autonomous aircraft. Those sensors capture signals across a wide area. Overwatch's own software fuses the raw signals into a single picture.
Three revenue streams are described, in sequence. Hardware sales with support contracts now. Maritime-Surveillance-as-a-Service next, meaning the customer buys the surveillance rather than the equipment. Data sales later. The company states the second and third as intentions, not as current activity.
The markets are set out in four phases, starting with hardware sales into South-East Asia and moving to a managed service for Australia and the Pacific Islands (FIG. 01).
The Non-ITAR Advantage
Overwatch highlights the non-ITAR origin of the technology core among the company's barriers to entry, in a single mention. ITAR is the American regime that restricts where United States defence technology can be sent. Because the Overwatch core is European and Australian rather than American, it can be sold to buyers that US-origin equipment cannot easily reach.
For a company selling into South-East Asia, that is a commercial advantage rather than a technical footnote. On Samso's reading, that narrows the field for a government wanting persistent maritime surveillance without entering the American export-approval system. The prospectus pairs the non-ITAR origin with the company's alignment to AUKUS and Five Eyes priorities and its existing government relationships, and treats the three together as its barrier to entry.
The Polus Licence and the Related Party Behind It
The sensing technology at the heart of the product is not Overwatch's. It is licensed from Polus, a European radio frequency and autonomy company, under an exclusive licence covering specified territories across the Indo-Pacific. Overwatch paid a one-off start-up fee of US$350,000 and, per the prospectus, pays no ongoing licence fees or royalties. A licence with no royalty running against it is better terms than most small companies get.
What Overwatch owns is the layer above. The prospectus describes a proprietary AI data fusion platform that takes signals from the Polus core and from other hardware and combines them into one intelligence picture, and the company owns the resulting data outright.
The Polus technology is protected by trade secrets and confidentiality agreements rather than patents. The company explains this as deliberate, because a patent would publish the technical detail. The trade-off is that the protection is harder for an outside investor to inspect.
Polus is a related party. Its founder and chair, Niv Karmi, co-founded Overwatch, holds 22.39 per cent of the company before the offer, and will be retained as a consultant and advisory board member after listing. A company associated with him is paid A$15,000 a month. The prospectus states the licence terms were negotiated at arm's length with board approval. A related party is a person or entity close enough to the company that a transaction cannot be assumed to be at normal market terms, which is why it has to be disclosed [R1].
Section 6.9 of the prospectus lists the Polus licence first among the company's significant dependencies.
Where the A$8 Million Goes
Funds available after listing are A$9,130,000, being the A$8 million raised plus A$1,130,000 of existing cash. The company states this covers two years of full operations, and the split is shown in FIG. 02.
The company also states it may not be self-funding from its own operating cash flow at the end of the two years, and that further debt or equity may be needed. That is in the prospectus, not an inference drawn from it.
Orders Received, Revenue Not Yet Recognised
Overwatch reports commercial orders with a total contracted value of approximately A$3.8 million. Of that, approximately A$2.88 million has been invoiced and approximately A$1.88 million has been received in cash. There are two key government customers, and the existing orders come from the Indonesian government through a local reseller [R1].
No revenue has been recognised. The money received is carried as contract liabilities, an accounting term for cash a customer has paid for goods or services that have not yet been delivered. It becomes revenue once delivery is complete, which the prospectus states is still in progress.
Money received from real government customers is a genuine difference from a company listing on a plan alone. What has not yet happened is the delivery that turns it into revenue. The first half-year report will be the first public test of that.
Overwatch was incorporated on 7 August 2025. Before this offer it raised A$2.35 million in seed capital at 10 cents a share, and it holds a private ruling from the Australian Taxation Office confirming Early Stage Innovation Company status for the year to 30 June 2026, a tax classification that gives certain investors concessions.
The First Year's Accounts
Overwatch has one accounting period behind it, running from incorporation on 7 August 2025 to 30 June 2026. RSM Australia Partners audited it and issued an unqualified opinion, which means the auditor found no reason to qualify what the accounts say. BDO Corporate Finance Australia reviewed the figures for the prospectus [R1].
The company lost A$857,604 over that period, which for a company with no prior period is its accumulated loss to date (TABLE 02).

TABLE 02 shows a business with almost nothing in it besides cash, receivables and stock. Plant and equipment comes to A$7,914 and intangible assets to A$428,102. That is consistent with the capital-light model the prospectus describes, where the company buys other people's drones rather than building a factory.
The prospectus contains no revenue forecast. Section 7 carries historical and pro forma historical information only, with no prospective financial information of any kind. An investor is given what the company has done and what its balance sheet will look like after the raise. What it expects to earn is not in the document.
Pro forma cash after the offer is A$8,243,748. Taking that off the A$26.7 million market capitalisation at the offer price leaves an enterprise value of about A$18.5 million, which is Samso's own subtraction rather than a figure the company has published. Enterprise value is what the market is paying for the business itself, once the cash it is about to hold is set aside.
The Board, the Register and the Escrow
The board is small and weighted to the sector. Harry Karelis is Executive Chairman, Oscar Leslie is Managing Director and Chief Executive Officer, Nathan Munn is a Non-Executive Director after more than 20 years in the Australian Defence Force, and Michael Outram is a proposed Non-Executive Director and a former Commissioner of the Australian Border Force [R1].
Only Outram is assessed by the board as independent, and he is not yet appointed. The prospectus states the board intends to appoint further independent directors but gives no timing.
The prospectus discloses that Karelis was a non-executive director of Sapien Cyber Limited, which entered voluntary administration on 28 February 2024. It states he was a director within the 12 months before that event, was not a director when it occurred, and held no executive role in that company's financial management.
The register is concentrated. Three entities hold 20,930,000 shares each, 22.39 per cent apiece before the offer, associated with Karelis, Leslie and Karmi. A fourth holds 7.97 per cent. After the offer, those three entities fall to 15.68 per cent each.
The math that follows is Samso's own, worked from the prospectus figures. Of the 93,500,000 shares already on issue, 70,000,000 went to directors and key management for nominal consideration at incorporation, priced in the prospectus notes at A$0.001 and A$0.0001 a share. The remaining 23,500,000 came in at 10 cents in the seed round, putting A$2.35 million of cash into the company. At the 20-cent offer price, those 70 million founder shares carry a paper value of A$14 million. New money is buying in at 20 cents alongside seed money at 10 cents and founder money at a tenth of a cent or less.
That structure is normal for an ASX float of this size, and the prospectus sets it out clearly. Escrow is what keeps those shares off the market. Escrow is the ASX requirement that certain shares cannot be sold for a set period after listing. FIG. 03 sets out which blocks are restricted and for how long.
About 61 per cent of the register is escrowed on the company's own estimate, which ASX has not yet confirmed. The options and performance rights are restricted too. Performance rights convert into shares only if stated milestones are met. None of the offer shares are held back, leaving a free float of approximately 38.8 per cent, which is the share of the company actually able to trade.
Samso Concluding Comments
Overwatch arrives with something most A$8 million floats do not have, which is money already received from government customers. Approximately A$1.88 million has come in against orders of approximately A$3.8 million.
Two things qualify that figure. It is not revenue yet. And it is not spare cash, because the prospectus lists existing cash reserves of A$1,130,000 going into the offer and carries the customer money as a liability with an obligation to deliver attached to it.
What an investor is buying at 20 cents is the execution of a plan to turn a licensed sensing capability into an Australian-owned intelligence business. The prospectus is clear that the sovereign capability, the in-house sensors and the data product are ahead of the company rather than behind it, and all of it is disclosed.
One repeat order from a second government would say more about this business than the current A$3.8 million says.
SAMSO TAKE The interesting question here is whether a small Australian company can build a data asset out of somebody else's sensor and end up owning the part that counts. Overwatch has told the market what it intends to do and roughly what it will cost, and it has customers paying before it has a listing. Two events would answer it, the first delivery that converts contract liabilities into recognised revenue, and a customer outside Indonesia. So the reader is left with this. If the non-ITAR core and the government relationships are the real barrier to entry the prospectus says they are, why has that not yet produced a second jurisdiction paying? |
THE OTHER WAY TO READ THIS A company incorporated in August 2025, with no recognised revenue, listing at a A$26.7 million market capitalisation on the strength of a licence it does not own, from a related party, with about 61 per cent of the register escrowed. Read that way, the offer buys a plan and a board rather than a business, and the A$8 million buys two years to prove it. Almost every favourable fact in this piece is a statement of intent rather than a result. The sovereign manufacturing is planned, the in-house sensors are in development, two of the three revenue streams are objectives, and even the A$3.8 million of orders has not become revenue because the deliveries are still running. An investor taking this view would say the disclosure is excellent and the execution is entirely ahead of the company. |
