Chatting Apton Acquisition with PacBio CEO Christian Henry
PacBio CEO Christian Henry chatted with me recently by teleconference on a variety of topics, but the focus was the recent PacBio acquisition of Apton Biosystems for $85M in equity. As a regular reminder, my employer’s CEO reports in a sense to Henry, as he’s on the Board of Directors.
A particularly interesting revelation by Henry is that PacBio had its eye on Apton in late 2021, essentially as soon as they completed the Omniome acquisition announced in July 2021 that formed the foundation for their now-released Onso short read instrument. PacBio believed then that the desktop instrument design from Omniome wouldn’t be sufficient; PacBio felt compelled to have a path to a high-throughput instrument. While they felt an internal effort was possible, an acquisition might shave many years off the timeline. And PacBio liked Apton’s concepts and launched into discussions and even made an acquisition offer to Apton’s management, but no deal was reached – but nor were any bridges burned.
About a year later, PacBio was at ASHG unveiling the Revio long read instrument and sent new feelers to Apton – let’s explore a collaboration marrying our chemistry to your instrument. Before long, just such a proof-of-concept instrument was underway, and in under two weeks positive results were in hand. Results weren’t as good as with the well-tuned Onso prototype, but nor were they discouraging – perhaps with tuning the gap could be closed. The proof-of-concept experiment didn’t have ideal density, the optics hadn’t been tuned and nor had the fluidics been optimized – the PacBio reagents had a significantly different viscosity than Apton had targeted. But billions of reads at “not quite Q40” quality. Henry particularly gushed over Apton’s optics, which achieve superresolution imagery but with rapid scanning times. This led to new discussions about what sort of structure any joint effort should take, which ultimately led to the acquisition – with PacBio particularly happy with the timing since the original Onso R&D effort was winding down.
So what will come out of all this? Henry sketched the idea of a floor-standing model generating billions of reads. Launch timing expectations aren’t being made public - Henry isn’t ready to put pressure on the development team – “yet”. Accuracy in the Q40+ range and billions of reads per flowcell. Run times in the 2-3 day range - Henry and I agreed that nobody is interested in returning to the two week sequencer runs common with the first generation instruments such as GAII and SOLiD. The unit would have sufficient onboard compute to perform the superresolution imagery processing as well as the downstream processing which is onboard the Revio. Likely to have either 2 or 3 flowcells per run – Henry said “definitely multiflowcell” but “probably not 4 like Singular”.
From a commercial point-of-view, Henry believes that first they can capture 1-3% market share in the liquid biopsy space to create a multi-$100M business. That’s a small slice of a big pie - Henry isn’t making grandiose claims here. But it’s also much easier to overshoot a small estimate than a larger one. Henry believes that the current Onso will be important in this market, but ultimately there needs to be a big machine as well.
He also sees the Onso instruments, and particularly an Apton-enabled high throughput instrument, as important for selling Revio and future long read instruments (more on that below). He was very gracious about competitors all around – in his view Element Biosystems, Singular Genomics, Oxford Nanopore and the rest are important counterweights to PacBio drifting into hubris and complacency.
Some observers such as this scribe worry that the Onso short read platform will distract attention from the long read Revio/Sequel platform, but Henry is clearly still very invested in the long read side of the business - and a strong believer in sales synergy between the long read and short read instruments. Globally, PacBio is seeing success selling Revio plus Onso bundles. He sees the size of the commercial organization – now over 200 people – as an edge against small players like Element and Singular. Revio, he says, is performing well in the field and performance enhancements will be coming late this year or early next year. That might include library preps from 100 nanograms or less of input DNA. And 40% of Revio orders are to new customers, not previous Sequel line owners. And with increasing interest in the small fraction of long DNA fragments in cell-free DNA, Henry sees possible crossover between the Onso focus on cell-free DNA diagnostics (aka liquid biopsies) and the long read business – but also that competition in this space “keeps PacBio honest”
Henry says that PacBio is “deep in development” on a next generation SMRTcell, designed to enable 10K 30X human genomes per year – and many population genetics studies are opting for 12-15X coverage so that might be multiplied by a bit more than a factor of two (and with current Revio, that brings each samples slice of the flowcell to about $500). At the other end, development of a benchtop system with a “dramatically lower” pricetag is well under way. PacBio is also investing heavily in computational biology, viewing long read computational biology as still having a lot of catching up to do relative to short read computational biology.
With regard to Oxford Nanopore, Henry frequently grants compliments – but is also fiercely competitive. So in one breath he praises MinION as a great product and “we won’t touch them”, but the next touts Revio for large scale long read studies. He claims that the all in cost of Revio is better than Oxford Nanopore (a claim I’m sure ONT would contest – everybody, get out your green eyeshades!). Henry noted that at current duplex rates, large oversampling is required on PromethION to cover a genome – which I’m sure ONT would counter with “wait until the next release of duplex”. Henry claims that one “major institution” took delivery of a Revio and then mothballed their Oxford Nanopore instruments.
For cell free DNA in particular, Henry is very bullish on Onso’s accuracy being a major advantage. In a head-to-head comparison of Illumina with Unique Molecular Indexes (UMI) and Onso without UMI, Illumina required four times as much data to achieve a similar level of accuracy. Translational genomics player TGEN decided on an Onso plus Revio bundle after seeing this sort of quality improvement. But Henry conceded the for most germline variants the advantage might not appear – though he did qualify this with a comment that Illumina’s filtering can lose coverage in some tricky spots in the genome.
It’s so much fun to track a space that is absolutely cutting-edge in terms of technology yet still has so much innovation bubbling. Apton and Omniome decided that the best route to market for their technologies was to be acquired; Ultima, Element and Singular are trying the independent route. Acquisition isn’t a panacea - I’m sure anyone who worked passionately on LaserGen was floored by Agilent’s decision to shelve that technology, and if I had spent long hours on Genia or Stratos I’d be unhappy with Roche’s inability to launch a sequencer. Onso is still early in its launch phase in a crowded market, with more than a little skepticism in social media as to whether it can carve out a niche. It will take at least a year or two before we can really assess Henry’s bullish position on the technology, and perhaps another couple of years before we see Apton technology in the field. But for me, watching all this unfold never begins to bore

PacBio Revio: Same Footprint, 80% The Time, 15X The HiFi!
PacBio has been rolling out announcements around the ASHG meeting and now delivers a huge one: the next generation SMRT instrument “Revio” will roll out next spring and it’s a big step up in throughput. With Revio’s 15X boost in per-run throughput over Sequel IIe, PacBio is touting this as 30X HIFi genomes for under $1K sequencing consumables per genome.

General Inception Aims to Ignite New Company Formation
A week ago, a company calling itself General Inception emerged from stealth as a new concept, which they call an “Igniter company”, to promote the formation of new life sciences company. As described to me in a phone conversation with General Inception CEO Paul Conley, General Inception provides a range of science and business expertise and support to enable embryonic ideas to condense into functional startups.
The igniter metaphor Conley offered me is the spark plug of a car: it is required to start the engine and continues to provide a key part of the functioning whole. Conley extended this to say that General Inception plans to go for the ride, but let the scientific founders occupy the driver’s seat. But another ignition metaphor occurred to me, the skill of turning a tiny spark from flint and steel into a raging campfire. Without careful nurturing, most tiny sparks will never ignite a blaze; only with careful and staged addition of oxygen and fuel does this reliably occur.
General Inception is not a fund, Conley stressed, but structured as a corporation. The ultimate goal is to make systematic and reproducible the generally artisanal craft of discovering and nurturing new ideas – as well as sometimes terminating efforts early that do not appear successful.
So what does General Inception offer? First, some of the boring business functions such as quotidian finance functions such as paying bills. Also a wide range of expertise, from access to technical experts in a diverse set of biological disciplines to persons familiar with estimating markets and development paths. General Inception has lined up Contract Research Organizations and Contract Manufacturing Organizations, but not just as contract partners – General Inception has “meaningful” equity stakes and perhaps board seats in these companies. A key goal of General Inception is to identify key experiments which can be run quickly at these partners to test project concepts. This might be simply reproducing results from an academic lab or perhaps running a key experiment to de-risk the project. An example of a CRO partner is Triple Ring Technologies, which offers company incubator services and facilities both in the San Francisco Bay and Boston areas.
Interestingly, General Inception is casting a very wide net. Any life science concept is potentially a target: therapeutics, diagnostics, tool companies, agriculture, synthetic biology or whatever else is centered around biotechnology. Within the company there are defined practice areas: Tools & Diagnostics; Cell Engineering & Synthetic Biology; Therapeutics. But these are intended not to be siloed fiefdoms but rather foci which overlap each other and reinforce each other. After all, so many technologies are converging - a diagnostic may require synthetic biology or a therapeutic cell engineering. Conley believes human health will continue to grow – but non-health life sciences might grow even faster and overtake healthcare in terms of total economic value, so he is positioning the company to support company formation in all areas.
In terms of geography, not only are they scouring US labs but also in Europe. In the latter case, the companies that emerge might have R&D remaining in Europe but commercial operations headquartered in the US. Conley says the venture environment in Europe remains more conservative than the US, so General Inception can make a particularly large impact in Europe by helping ideas cross “the valley of death” to where a venture firm is comfortable investing in it.
Not only is General Inception stalking the halls of academia, but they are also talking to existing companies about dormant assets that might find new life in a startup. And General Inception hopes to form long-term relationships with innovators; having an idea fail early won’t be held as a demerit against the academic.
In terms of deal structures, General Inception looks to set themselves up as a founder, with founder’s common stock. Generally they would be funding companies at the seed or pre-see stage, perhaps taking the place of angel investors or “friends and family” investments. Venture capital firms often demand preferred stock, which gives them first rights to the financial carcass of failed ventures - General Inception will be taking the same risk as scientific founders of not getting anything from liquidated companies.
General Inception itself has raised $60M from a set of venture capital firms. Their goal is to reach a steady state in which around 25 companies are seeded and graduated annually. General Inception also sees itself as evolving to an information business – with a large experience base of startups they hope to glean new insights into predicting what ideas work and finding the best company structures to maximize the chance of success. Venture firms that invest in General Inception will have early access to companies incubated by the company. Conley has been piloting the company since February 2020, refining the approach and the set of expert resources which General Inception can draw on
In my career I’ve interacted with startups in a variety of contexts - as a potential employee or consultant, an actual employee or consultant and as a potential or actual partner. I’ve also daydreamed a rough business plan or two. I will be the first to proffer that this is hardly a comprehensive exposure to the variety of ways that companies are seeded. Thinking back on experiences such as Warp Drive, I can see the value of quick proof-of-concept experiments to either validate a company or simply nip off an idea that is unlikely to ever bear fruit – but I also know how complicated it can be to identify such experiments or assemble all the components to perform such an experiment. So I’m intrigued by General Inception and wish them well, though I reserve a certain amount of skepticism that starting new companies will ever be anything other than artisanal.
