If you’re into frontier tech investing, think quantum computing, defense-tech, autonomous vehicle brains, then today’s piece is for you. I’m going to walk through four under-the-radar stocks trading under about $8 (current pricing subject to change) that are showing signs of breakout potential but also carry meaningful risk. We’ll look at Quantum‑Si Incorporated (QSI), Indie Semiconductor, Inc. (INDI), ZenaTech Inc. (ZENA), and a bonus wild card SEALSQ Corp. (LAES).

This is not advice to buy or sell, just a detailed commentary spotlight. Use it as part of your due diligence. If you like this kind of deep-dive tech analysis, keep reading, and if you find it valuable you can share it on LinkedIn/META or drop a comment below.

1. Quantum-Si (QSI) — The Proteomics / Tech-Hybrid Moonshot

Quantum-Si is a U.S.-based life-sciences / deep-tech company that builds next-generation single-molecule protein sequencing platforms. In plain speak: they’re trying to build the tools to detect and analyse individual proteins, at high sensitivity and throughput. Their tech merges biology, chemistry, AI and semiconductors.

While it’s not a “classic” quantum-computing company, it sits in that broader frontier-tech space (and so often gets discussed in similar contexts). Note: one reddit contributor put it bluntly:

“QSI is a Biotechnology company … this constant mis-labeling is only harmful.”

Recent momentum & financial snapshot

According to Simply Wall St, QSI’s TTM (trailing twelve months) revenue is extremely small in absolute terms (~US$3.4 m) and still unprofitable. Market commentary shows cash burn and dilution risk are high; their technology roadmap and commercial adoption are still yet to scale. They announced a collaboration with NVIDIA Corporation to develop an acceleration platform for their sequencing tech.

Why it might be interesting

For investors comfortable with high risk/high reward, the thesis is: if Quantum-Si executes, their technology could unlock major growth in proteomics, diagnostics, and life sciences.

It trades at a relatively low share price compared to traditional large cap tech/biotech, meaning a breakthrough could lead to substantial upside.

On the flip side: revenue is tiny, profitability is far away, and many execution/market risks remain.

Key catalysts & things to watch

Quarterly earnings / revenue growth or guidance that accelerates meaningfully.

Any major commercial adoption of their instrument/platform in labs or diagnostics.

Financing events (raises, partnerships) that bolster cash runway.

Dilution risk: watch capital raises.

Technological milestones: instrument launches, greater throughput, lower cost.

And again: remember, this is speculative.

2. Indie Semiconductor (INDI)

Indie Semiconductor is a U.S.-based semiconductor company, focusing on intelligent systems for automotive (EVs, ADAS), IoT, sensor fusion, and smart mobility. Think “the brains” behind next-gen smart vehicles. They recently acquired a perception/vision-software company (Emotion3D), signalling that they intend to expand from purely hardware into intelligent system solutions.

Financials & risk landscape

Their Q2 2025 non-GAAP gross profit was $25.35 m, with a non-GAAP gross margin around 49%. (per their investor release)

But net profit is still deeply negative (their trailing twelve-months net margin is -61%) meaning they’re burning cash.

They have decent cash on the balance sheet (for a small chip company) and manageable debt, but the auto-semiconductor space is highly competitive, cyclical, and exposed to macro headwinds (EV slowdown, chip supply chain issues, price pressure).

Why this might catch fire

The shift to electric vehicles, autonomous driving, smarter sensors and edge computing in vehicles is real. If Indie can lock design wins, scale, and convert software + hardware into margin growth, they might ride that wave.

Trading under $8 puts them in bargain/hyped territory compared to larger auto chip firms.

But: auto semiconductor cycles are tough; delays matter; competition from bigger players (Infineon, NXP, Qualcomm etc) is intense.

What to watch

Automaker or Tier-1 supplier announcements using Indie’s chips/solutions.

Margin expansion in future quarters (moving toward profitability).

Supply chain improvements/any shortage alleviation.

Software integration success (the Emotion3D acquisition).

Macro auto trends (EV demand, regulatory shifts, regional auto growth).

3. SEALSQ (LAES) — The Wild Card: Post-Quantum Security & Semiconductors

As a bonus, consider SEALSQ (ticker LAES). They are not a household name but they are involved in post-quantum cryptography (hardware/semiconductor + security) which is a niche yet potentially huge future market. They have announced a joint venture in India with a large local semiconductor company to establish “India’s first secure semiconductor center for post-quantum / secure chips”.

Recent Highlights

LAES stock jumped 60% in a single week on news of:

• A partnership with Wecan to combat quantum hacking
• A role in a SpaceX-linked satellite communications project
• A $60 million equity raise to fund post-quantum initiatives

The firm also acquired IC’ALPS, a French ASIC design company, and announced plans for a quantum semiconductor center in Spain expected to generate $25 million in revenue by 2026.

Financials & Risks

In 2024, SEALSQ earned $10.98 million in revenue but reported $21.2 million in losses.
Analysts remain optimistic, with some “Strong Buy” ratings and a $6 target price.

Still, dilution risk from the equity raise and execution challenges in PQC remain significant.

Snapshot & risk

The concept: as quantum computers mature, cryptographic systems will need “quantum-resistant” solutions. Companies that build that hardware/software could be in a new growth frontier.

But: their revenue base today is small, profitability far away, and execution risk is high. Technology must deliver, markets must adopt, and defence/security markets must open.

Also: “wild cards” by definition have higher downside risk.

What to watch

Progress in the Indian JV becoming operational (milestones, revenue recognition).

Contracts in post-quantum cryptography with defence/government customers.

Product certifications, chip manufacturing progress, supply-chain announcements.

Any dilution/financing events (which often accompany early stage growth companies).

4. ZenaTech (ZENA) — Drone as a Service + Defense Pivot
Business model & focus

ZenaTech (Canadian HQ, trades U.S. NASDAQ as ZENA) is positioning itself in the drone-/defense-technology space with a “Drone as a Service” (DaaS) model. Rather than just selling drones, the business model is service + operations + maintenance + payloads.

They are targeting U.S. defense/government customers, dual-use manufacturing (commercial + defense), and lightweight drone platforms (IQ Nano, IQ Square) for specific missions.

Momentum & risk profile

Their stock price has shown large jumps (indicative of high speculation).

Public financial details are less transparent/strong compared with larger peers (makes it more speculative).

Risks: regulatory/defense contracting is complex, manufacturing scale for drone platforms is tricky, operating service model is different/burdensome (maintenance, training, liability), tech competition is intense.

Why it could be interesting

If a meaningful government contract or defense-agency win comes through, the upside could be rapid.

The DaaS model is interesting because it can generate recurring revenue rather than one-off hardware sales.

At a low share price, the risk/reward could appeal to frontier tech speculators.

Final Thoughts

Quantum computing and frontier semiconductor tech are rapidly evolving sectors, filled with opportunity, volatility, and risk.
Whether it’s Quantum-Si’s biotech potential, Indie’s smart vehicle chips, ZenaTech’s drone defense expansion, or SEALSQ’s quantum cryptography edge, these four stocks represent the cutting edge of innovation under $8.

But remember: speculative tech investing requires patience, diversification, and due diligence.
