Drones have become a potent military threat, particularly on the small scale. Nimble multi-rotor drones are fast, difficult to spot, and can cause plenty of harm if allowed to go about their work unhindered. The first step to dealing with this issue is detection—a problem that [Agam Rossen] has put some work into.

The result is VolAnti—an open-source drone detector. This route was chosen as a reliable way to detect incoming multi-rotors, since spinning propellers tend to create a telltale sound that can be plucked from the noise quite specifically. In a world where fiber optic drones eschew RF emissions, it also proves particularly useful for early warning of such craft.

VolAnti relies on a small four-microphone array, with the I2S output of all four mics summed together. The output is then fed into a 2048-point FFT running every 32 ms on an ESP32-S3. A comb score is given to try and pick out different blade rates from 70 Hz to 2000 Hz. Multiple detection algorithms run in parallel, because [Agam] noted a problem—using an adaptive noise floor would miss drones that arrived in the area and hovered in place. With the noise not varying, it would get filtered out by the adaptive floor, so one algorithm in the four runs with no floor to catch drones that aren’t moving. Files are on GitHub for those curious to learn more.

We’ve featured other acoustic detection projects before, too. If you’re working on something similar, or conversely, you have the inside scoop on how to hide a drone’s noise signature, don’t hesitate to let us know on the tipsline.

The computer business in 1984 was a bizarre mix of hobby-level companies, a few small companies that had made it big, and a lot of big companies starting to take notice of personal computers. Plenty of money followed, which led to strange products and even stranger ads. [Such Bad Tech Ads] reveals a very bad ad from that time for a product we have barely heard of: the Spartan. The Spartan’s job was to convert your Commodore 64 so it could run Apple ][ software. The ad campaign had, inexplicably, a mime. We think. Or maybe a clown. Hard to say.

On the face of it, the Spartan might not be a bad idea. In 1984, there was plenty of Apple software. Well, relatively, anyway. But a Commodore computer was far cheaper. Other conversion kits like the Intel Inboard/386 managed to find some success in the market later. The problem, outside of strange ads, was one of timing.

If the product was available in 1984, it might have worked out better for the Canadian company, Mimic, behind it. Instead, it was about two years before an actual piece of hardware would show up in anyone’s hands. By that time, there was a ton of software for the Commodore 64. Not to mention that even when Mimic announced the Spartan, Apple had discontinued the Apple ][+ computer.

Why use a mime to promote a product that turns your Commodore 64 into a keyboard and monitor? We have no idea. But he was in all the ads and even on the product box. Strange.

We’ve seen the Spartan before, naturally. Being late usually has bad consequences. Ask FedEx.

A surprising number of things we use in everyday life retain most of their design cues from their 19th century ancestors. The bicycle retains the same basic design as it had in 1890, as does the sewing machine, the toilet, the car, and of course, the keyboard and the QWERTY layout from old typewriters. But we aren’t doomed to have our technology perpetually living in the past. [Paul] wanted a keyboard designed around human hands, rather than being designed around a machine, so he built this unique split keyboard.

The design of this specific keyboard went through around 50 iterations before he was comfortable with it. Other design goals here were for it to be portable, and the split nature of this certainly makes it more compact as does the use of low-profile switches. Each finger’s column is angled and spaced based on the needs of that finger, with the ring finger keys sitting higher and the index finger columns angled inward. Each thumb has access to three keys, one of which is the spacebar and the other two layer keys, which is what enables this design to get down to only 36 total keys.

When thinking about it for any length of time, the modern keyboard’s design holdovers from the 1800s are fairly wasteful compared to this split, ergonomic version. Especially when looking at the spacebar, which ties up both thumbs and only performs a single task, there’s a lot of opportunity for modern designs to be more efficient, more portable, and easier on one’s body. Feel free to take this to the extreme and use all three dimensions, as long as you aren’t particularly concerned with portability.

Highspot’s branding is still everywhere inside its longtime headquarters at World Trade Center East, overlooking the Seattle waterfront. But outside the corner office that once belonged to the sales software company’s co-founder and CEO, “Seismic” is scribbled on the whiteboard.

That’s how fresh the merger is. Two weeks after San Diego-based Seismic took over its Seattle-based rival, Seismic CEO Rob Tarkoff is in town this week for the first board meeting since the combination was completed, and the inaugural gathering of the combined company’s senior leadership team.

Highspot and Seismic sell sales enablement software: systems that manage the pitch decks, case studies and training materials salespeople use, and track which ones help close deals.

Founded in 2011 by Robert Wahbe and two former Microsoft colleagues, Highspot raised $650 million and held the top spot on the GeekWire 200, our ranking of the region’s privately held tech companies, prior to the merger. Wahbe, its CEO until the deal closed, is now on Seismic’s board.

Tarkoff, a lawyer by training who spent much of his career in corporate development and M&A, became Seismic’s CEO in October 2025, succeeding co-founder Doug Winter. He had previously spent seven years running Oracle’s customer experience business.

The Highspot deal was announced in February, four months into his tenure.

Tarkoff addressed a wide range of questions from GeekWire in an interview Monday afternoon in Wahbe’s former office, which now serves as an ad hoc meeting room.

Here are the main takeaways from the interview:

A $600 million company: Tarkoff disclosed the combined company’s annual recurring revenue for the first time, putting it at about $600 million, with about $200 million of that coming from Highspot.

That makes the combined business three times the size Highspot was on its own and 50% bigger than Seismic. Tarkoff said the larger size will be an adjustment for people across both companies as they come together. “We’re getting closer to being a billion dollar company,” he said.

The companies did not disclose the financial terms of the deal, and Tarkoff declined to say whether the transaction put Highspot above or below the $3.5 billion valuation it reached in 2022.

Tim Porter, managing director at Madrona, which led Highspot’s Series A in 2014, called it a “multi-billion-dollar merger” in a post after the deal closed. Porter, who serves as a board observer at Seismic following the combination, wrote that Madrona hopes to help build the combined company into “a truly iconic AI software company, through a potential IPO and beyond.”

Permira, the private equity firm that has backed Seismic since 2020, remains the controlling shareholder of the combined company.

Impact on jobs: Seismic said when the deal closed that Highspot had more than 700 employees and that the combined company would have about 1,700 total. Tarkoff said in a statement at the time that the companies were “carefully evaluating our organizations to identify areas of overlap,” and that “any decisions will be communicated directly and proactively to employees.”

Since then, word of initial job cuts has started to emerge on LinkedIn and other online forums, but the company has not provided specifics or disclosed any numbers.

Asked for an update on job reductions this week, Tarkoff said, “We did our best to try to find roles for everybody that we could, but there’s always some level of overlap where you don’t need two people doing a task that requires one.”

Tarkoff did not provide numbers or address the question of whether more job cuts are coming. He said the company feels “really good about where we are from a go-forward staff perspective,” while adding: “We will continue to push performance and push growth and acceleration.”

Seismic’s future in Seattle: Tarkoff said Seismic will keep Highspot’s Seattle offices at World Trade Center East, where the company has a long-term lease. He called Seattle “one of the top centers of excellence for tech talent,” citing the ability to recruit from Amazon, Microsoft and others.

There will be no designated Seattle site leader, he said, describing the office as one of the company’s major centers rather than a headquarters.

However, several senior leaders of the combined company are based in Seattle, including Kurt Berglund, who led engineering at Highspot and is now Seismic’s senior vice president of AI.

Others include chief human resources officer Kimberly Schultz, who joined Seismic in June after 11 years at Amazon, where she led the team responsible for integrating acquisitions and divestitures, and Lucas Welch, VP of brand and communications, who spent nearly eight years at Highspot.

Tarkoff said a number of the company’s top engineers are based in Seattle as well.

Seismic’s other major locations include San Diego, Boston, Toronto, Vancouver, B.C., London and Hyderabad, India, where Tarkoff said the company has more than doubled its presence. Gurpreet Singh Pall, who was Highspot India’s chief operating officer, now leads Seismic’s India operations.

Product plans: The current Highspot and Seismic platforms both will continue to be sold and supported for the time being, Tarkoff said. He declined to set a timetable for eventually consolidating them, saying customers will move to a new platform when one is ready.

Now that the companies are able to work directly together, he said they’ve come to see that the two products are closer than he understood before the deal closed. Seismic has focused on complex enterprise workflows and regulated industries, financial services in particular, while Highspot built for a broader market of upper mid-market and lower enterprise customers.

With two teams no longer building the same things, he said, engineering can move to new work — more AI agents, additional content governance features, and deeper industry-specific workflows such as archiving and records retention.

Rivals are making the opposite case. Ali Akhtar, CEO of Letter AI, wrote in a LinkedIn post last week that mergers in the category turn companies inward for quarters or years, predicting “stalled innovation, layoffs, and distractions from delivering customer value,” and a period of reduced support for customers on legacy platforms. Akhtar is offering to buy out their contracts.

Pricing: Tarkoff said seat-based subscriptions aren’t going away, because enterprises want predictable costs. He said he’s skeptical of the usage-based pricing some AI vendors have adopted, pointing to high-profile examples of companies blowing past their budgets.

“Token-maxing is not really a good model long term, because it’s just going to force enterprises to use less,” he said.

He said Seismic is working toward pricing tied to outcomes rather than usage.

The Salesforce question: A week after the Seismic-Highspot merger closed, Salesforce and Anthropic announced Claudeforce, making Claude the default model across Slack and parts of Salesforce’s Agentforce platform.

Salesforce is both a channel and a rival for Seismic. Seismic’s software sells through the Salesforce AppExchange, and its Aura AI runs inside Agentforce, Salesforce’s agent platform. At the same time, Salesforce’s Sales Cloud includes its own sales enablement tools. And Agentforce agents increasingly do work that enablement platforms have owned.

Asked whether the partnership makes Salesforce a tougher competitor, Tarkoff said no.

As sellers start working inside Claude rather than inside individual applications, he said, the assistant will call each company separately — Salesforce for customer records, Seismic for approved content and sales materials. That makes Seismic a peer of Salesforce inside Claude, rather than an add-on inside Salesforce’s own product.

“It actually puts us more on an even playing field with Salesforce,” he said.

But Salesforce is considerably further along. Claudeforce launched with a Salesforce plugin carrying 37 prebuilt sales skills, in pilot now and due in open beta this month.

Much of the early analysis of the Salesforce-Anthropic partnership saw it as evidence that enterprise AI is consolidating around a few deep platform alliances rather than opening up.

Seismic’s next fiscal year begins Feb. 1. Tarkoff said he expects to spend much of the intervening months on the road with customers and employees. Seismic plans to give the first detailed look at its new product roadmap at its Shift conference, Oct. 12-15 in Carlsbad, Calif.

Seattle-based cannabis data analytics company Headset has agreed to pay more than $1 million to resolve allegations that it improperly received and obtained forgiveness for a federal Paycheck Protection Program (PPP) loan.

The settlement, announced Monday by the U.S. Attorney’s Office for the Western District of Washington, stems from a May 2024 whistleblower lawsuit filed by Sidesolve LLC under the False Claims Act. Sidesolve is a data analytics company that uses AI algorithms to hunt for potential pandemic loan fraud across public records.

The government alleged that Headset was ineligible for the Small Business Administration (SBA) loan it received in February 2021 — and had forgiven in August 2021 — because its work supporting the marijuana industry conflicts with federal law.

Under the terms of the deal, Headset paid $100,000 within 30 days of signing the agreement in early August and will pay the remaining balance of more than $900,000 over four years through August 2030. The company made no admission of wrongdoing, stating it agreed to the payments to avoid the risks and expense of litigation.

Headset was founded in 2015 by Cy Scott, Brian Wansolich, and Scott Vickers. The trio previously co-founded Leafly, the popular online cannabis strain database and marketplace, which was acquired by Privateer Holdings in 2011. After departing Leafly, they launched Headset to bring business intelligence and real-time sales metrics to the legal pot industry.

The startup functions like a Nielsen for the cannabis sector, aggregating point-of-sale data from dispensaries and retailers to provide market trends, pricing insights, and consumer demographics.

Over the years, the company has raised $29.4 million in total funding from investors including Poseidon Asset Management and Canopy Rivers, expanding its data coverage across legal state and international markets.

The unexpected interruption came hours before the president wrote a congratulatory post on Truth Social about the company’s most recent earnings report.

Although digital photography took a big bite of the film industry’s lunch, it wasn’t able to completely eliminate the need — or desire — for photographers to use film in some situations. But digital information from a camera sensor can be manipulated to augment the natural physical capabilities of a camera in ways not really feasible for film. High dynamic range images, focus and exposure stacking, and automatic panoramic stitching. This camera takes the latter example to the extreme.

[Philo]’s proof of concept was a smartphone camera set on a chair and rotated around a room. Some software grabbed a single column of pixels as it moved and stitched them all together to form an image. This came out well enough that the idea was refined a few times, but it wasn’t until a single-line digital camera meant for imaging assembly lines was found that this really took off. Using the camera and some custom software, [Philo] was eventually able to take some of the longest panoramic images we’ve seen, using things like railways and boats as the track the camera rides on, with accelerometer data to help stabilize the image.

The results speak for themselves. There’s a bit of wobble from the movement of the various vehicles despite the accelerometer data, but given that the image is coming from a sensor meant for examining conveyor belts, it’s hard to complain. Of course, if you want to stick to film, there are panoramic film cameras available too even if they don’t quite have the reach of this digital one.

Highspot’s merger with Seismic was completed Tuesday morning, ending the Seattle-based sales software company’s run as an independent business and folding one of the region’s biggest enterprise technology players into a San Diego-based rival.

The combined company is now operating under the Seismic name, led by Seismic CEO Rob Tarkoff. Highspot co-founder and former CEO Robert Wahbe is expected to join Seismic’s board of directors, as announced in February. Permira, the private equity firm that has backed Seismic since 2020, remains the controlling shareholder.

The Highspot name isn’t disappearing entirely. Its product is now branded “Highspot by Seismic.”

Tuesday’s announcement named Seattle as one of the R&D locations — along with San Diego, Boston, Vancouver, Toronto, London and Hyderabad and other sites — where the combined company’s 700-plus product, engineering, data science and AI employees are based.

Seismic will keep Highspot’s Seattle and Vancouver offices, adding to its global footprint, Tarkoff said in a statement responding to GeekWire’s questions.

The combined company has about 1,700 employees globally. Highspot’s total headcount was more than 700 at the time of the deal closing, according to Seismic. The company didn’t say how many of those employees are in Seattle.

“As with any merger of this scale, Seismic and Highspot are carefully evaluating our organizations to identify areas of overlap and integrate our company for near and long-term growth,” Tarkoff said. “Any decisions will be communicated directly and proactively to employees.”

Seismic says it has 2,500 customers and 3.5 million users, and plans to invest more than $100 million a year in research and development.

Financial terms of the deal, originally announced in February, were not disclosed. Highspot had raised $650 million since launching in 2011. Its last publicly disclosed valuation was $3.5 billion, set in 2022 when it raised $248 million in a round led by B Capital Group and D1 Capital Partners.

Other backers included Madrona, ICONIQ Growth, Salesforce Ventures, Sapphire Ventures and Tiger Global Management.

Highspot held the No. 1 spot on the GeekWire 200, our list of the top privately held tech companies in the Pacific Northwest, until the merger was announced in February. Companies come off the list after mergers and acquisitions that fold them into other entities. Everett-based fusion energy company Helion Energy took over at No. 1 in the March update.
