Welcome to Back or Bolt, a newsletter highlighting what is happening in the world of early-stage investing/crowdfunding. I’ll provide a curated list of what’s new in the crowdfunding space around the world and one deep dive into a company of interest, then it is up to you whether to BACK OR BOLT!

The DEEP DIVE - PUIR Imaging

This Austrian MedTech startup is converting any ultrasound machine into a 3D AI imaging platform, aiming to improve outcomes for patients. The company is burning €290k a month on a mere €586k in annual revenue, but plans to achieve €7.6m in two years. Is that enough to justify their €30m valuation, or will they succumb to the pressure like many MedTech startups before them?

The Good

  • The technology is unique. Ultrasound has been 2D for 50 years. PIUR's hardware add-on converts any existing ultrasound machine into a tomographic 3D imaging device in a single 30-second sweep - no new machine required, no radiation, no expensive MRI. A radiologist currently has to simultaneously obtain and interpret a 2D image, which takes longer and depends heavily on individual skill. PIUR separates acquisition of data from analysis entirely, enabling telemedicine workflows that simply don't exist with current 2D ultrasound.

  • FDA approval and CPT-I reimbursement has been obtained. Most MedTech companies get stuck at one or the other. PIUR has both - and the CPT-I code (76377) means US hospitals can bill an additional $110 per examination just for using the device. That's not a nice-to-have; it's the difference between a product a procurement team has to fight for and one that pays for itself. Competitors Koios and Amcad only have CPT-III codes, which offer lower and less reliable reimbursement.

  • 6 patent families across the US, Europe, Australia, China and Canada protect the core tracking and 3D reconstruction technology. Two are fully granted in all four major regions and are directly embedded in the FDA-approved commercial product.

  • GE HealthCare is a distribution partner. GE has 35%+ of the global ultrasound market. PIUR technology is deeply integrated into GE devices - not just co-marketed - and the joint European go-to-market is already live. The US launch with GE is planned for December 2026.

  • $30m ARR pipeline includes NYU (50 locations, $3.6M ARR potential from one account), Mayo Clinic, Mass General, and Columbia University, who are already paying customers.

  • The investor base contains Ascend Capital Partners (€3.67M invested), Aescuvest (€5.56M invested), Heinz-Walter Grosse (former CEO of B. Braun, one of Europe's largest MedTech companies), Christian Braun (B. Braun family), Udo Vetter (Vetter Pharma), and Josef Schabauer (former MD of Abbott Austria). These are not run-of-the-mill angel investors writing small cheques but are MedTech industry insiders who understand exactly what they are backing.

  • The exit strategy is clear. GE HealthCare, Siemens Healthineers, Philips, Canon Medical and Samsung Medison are all in competition for AI imaging capability. RadNet's acquisition of See-mode (a 2D competitor) shows the appetite exists. PIUR is the better asset.

  • €30M pre-money valuation against a comparable SaaS imaging AI peer group that trades at 10-20x ARR. If PIUR hits €7.6M ARR by 2027 as projected, €30M today starts to look cheap rather than expensive.

The Bad 🚩

  • The revenue is tiny relative to the ambition. €586k in 2025, and flat year-on-year. The transition from hardware sales to SaaS subscriptions explains some of this, but going from €586k to €5.5M in a single year (2027 projection) requires the NYU deal, the GE US launch, and multiple Tier 1 closures all landing on schedule. In enterprise MedTech, they rarely do.

  • The balance sheet is under pressure. Accumulated losses of €12.78M, negative equity of ~€391k, and roughly 7-8 weeks of cash runway before this raise closes. The €290k monthly burn against €49k monthly revenue means PIUR needs the second closing of this Series B (approximately €10M, currently in negotiation) to land within 12 months or the runway runs out. A term sheet is apparently in negotiation, but that is not the same as signed.

  • The sales cycle is slow. 9-18 months to close a Tier 1 US hospital account. NYU has been "approaching closure" long enough to feature prominently in fundraising materials. One delayed procurement decision at a large account cascades into a materially worse financial position at €290k/month burn.

  • The raise is via a profit participation certificate structure (Genussscheine) rather than equity. There are pros and cons of this system, and it is common in German crowdfunding, however you do not get shares for this raise only the right to participate in profit distributions and exit proceeds.

  • Founder dilution is striking. Co-founders Frederik Bender and Robert Bauer together hold only 9.11% of the company after this round, which is low for a Series B and suggests either aggressive dilution in earlier rounds or a structure that may create misaligned incentives as the exit approaches. The majority of equity is held by institutional investors, with Aescuvest alone at 23.86%.

  • GE dependency is a double-edged sword. GE is both the biggest distribution opportunity and the biggest strategic risk. There are no minimum volume commitments in the partnership. If GE decides to develop competing 3D capability internally, or acquires a competitor, PIUR loses its primary scaling channel. GE could also wait and acquire PIUR at a lower valuation if the second closing is delayed.

  • EBITDA breakeven isn't projected until 2028 - and that projection assumes ARR grows from €85k at end of 2025 to €20M by 2028. The revenue projections (52x growth in three years) are not impossible given the named sales pipeline, but they are aggressive, and the margin for error at current burn rate is thin.

Back or bolt?

⚡ This is one of the more genuinely difficult calls.

The technology is real, the regulatory approvals are real, the partnership is real, and the investor base is about as credible as you'll find in European crowdfunding MedTech. The CPT-I reimbursement code in particular is a detail that separates PIUR from the vast majority of MedTech startups - it means the product has a clear, validated economic case for US hospital buyers without requiring anyone to argue for budget.

But the raise comes at a time of maximum financial fragility. Seven to eight weeks of cash runway, a second closing in negotiation but not signed, a sales pipeline dependent on enterprise accounts with 9-18 month cycles, and a founding team that has been significantly diluted. The €30M valuation is not wrong, but it is priced for the future.

The instrument structure (profit participation certificates) also means this is best suited to investors who understand that they are not buying shares and have read the raise terms carefully.

If the second closing lands and NYU converts in Q3 2026 as projected, this looks like a very good entry point. If either isn’t achieved, the next 12 months get difficult, which is precisely what makes it interesting, and what makes it higher risk.

This is a tentative back. I think the product is strong, with clear demand and good traction. I am willing to take the risk of them not achieving their targets. The profit sharing structure is also of less importance as the amounts invested aren’t large.

I do have minor concerns around the forecast achievability as I have worked on a MedTech AI imaging client before, and while each company and product is different, I know this can be a difficult market to crack and achieving those pipeline sales is everything. My former client’s share price is down 84% at the time of writing, which I can only assume is due to not achieiving their planned targets. I’m optimistic that PUIR imaging will have more luck due to their distribution partnership and medical approvals, otherwise fool me twice.
