COVID-19 might have thrown a wrench in this health tech startup's fundraising plans, but it found a way to close an oversubscribed round anyways. Photo via Getty Images

When I wrote about fundraising early this year, I knew that I would be raising a round shortly, but had no idea I would be doing it in a changed COVID-19 world. I have experienced two unexpected recessions as an entrepreneur — in 2001 and 2008 — and each time causing huge struggles for entrepreneurs to raise funds. That is when I developed the mindset of acting like a desert rat, surviving with little help, learning to tap into the resources around you to survive and even thrive. Little did I know what was coming in March when the COVID-19 shutdown started.

Solenic Medical Inc. is a medical device company developing an innovative non-invasive treatment for infected metallic implants in the body. Using technology invented at the University of Texas Southwestern, Solenic will leverage the unique properties of alternating magnetic fields generated from external coils to eradicate biofilm on the surface of medical implants.

This non-invasive treatment addresses a major complication of various surgeries, such as knee and hip replacements, as well as in trauma related implants such as plates and rods. There are certainly challenges to fundraising for medical device companies, but each technology arena has its own challenges that I won't go into here.

The Solenic Medical team knew we needed to raise a round early this year, building upon the progress achieved since our founding investment in early 2019. The question was what type and size a round to raise.

We knew we were close to taking some valuable steps, but needed a just a little more time and funding to get there, at which point we figured we would be able to step up our valuation greatly. We decided on a modest $500,000 convertible note round, to help us accomplish at least a portion of the following items:

  • Recruit a reputable outside board member
  • Complete a planned large animal study stepping up from previous mice studies
  • Complete submission of a Breakthrough Device application to the FDA
  • Close our $1.3 million NIH grant and/or other non-dilutive funding
  • Fine tune simulation approaches to optimize the transducer design
  • File new intellectual property

We knew that some combination of these would occur in the succeeding months and would make it easier for Solenic to raise further funds.

The first domino was the on-boarding of an experienced technology executive from Virginia to join our board. The large animal study was delayed when the COVID-19 shutdown started, but our Breakthrough application and the grant application review started as the team went into virtual work mode. Progress was made on the simulations and drafting our next patent. The dominos were starting to fall in spite of the shutdown.

My philosophy was to treat the round as five different type of efforts, in pretty much five equal portions.

  • The first 20 percent in a round is always the hardest, even in closely held friends and family round. The first check regardless of size is always hard as often investors very interested in the round will wait for others to move first.
  • The second 20 percent is not much easier, still requiring a leap of faith by the investor.
  • The magic starts happening at 40 percent, where momentum picks up as you approach halfway and beyond.
  • At 60 percent you reach real momentum, where those investors who may have been waiting to move for a while now start moving.
  • At 80 percent you pick up investors who move quickly worried about missing out before the round closes.
  • With luck, you get enough momentum to oversubscribe the round and have to make the call to go beyond your target funds. For a quick hint on where I standard at that point, there's a saying that you never turn down money.

It was strange picking up the fundraising activity via zoom meetings, and it got off to a slow start as the initial circumstances of the new COVID-19 world settled in. Following my own advice from the January article, I started strategizing my communications, who might be the first check and first movers in first 20 percent, then the next 20 percent and so forth. For a friends and family round you start with your board as champions for the round, founders and management. No one is likely to be more committed and likely to get things started generally, much less in unusual financial times like a pandemic shutdown.

With an institutional co-founder like VIC Technology Venture Development and a passionate board we were able to jumpstart the round the round with $110,000 in commitments. This was quickly followed $100,000 from friends and family of board or management team members. Note that "quickly" in a pandemic was three months that in normal times might have taken only a month or so. Now that we had crossed that magic 40 percent hurdle, things started picking up speed, where members of the VIC Investor Network added individual investments totaling $140,000 to pass the next hurdle of 60 percent within another six weeks of individual presentations and discussions.

Momentum accelerated with friends and family and management team members stepping up to get us to 80 percent within few weeks. At the time of this article we are over-subscribed with more decisions to come. That is a great problem to have as things really picked up speed recently.

Though the final tally is to be determined the mix for this friends and family round looks to be pretty typical to past experiences

  • Board & Management – 27 percent
  • Family – 27 percent
  • Friends – 22 percent
  • Others – 25 percent

Because of the shutdown, this pandemic round has been unusual and at times frustrating, with some highly vocal and interested prospects going strangely silent as soon as the shutdown started, while others moved more slowly than originally expected. Regardless of how things transpired, it turned out largely familiar. As usual, the people you know the best and that know and trust you the most are the ones that are mostly likely come through for you. Building your network to increase the size of that pool is what you do far before a round starts.

Later rounds will be quite different, but the same 20 percent momentum stages will apply. It's a matter of building and nurturing a network of prospects in advance. Larger rounds involve an "institutional" friends and family network that you have known for a while. That work begins long before you start developing them as prospect for an open investment round. By the time this article is published, we expect to have the final funds of this round in the bank but have already started building relationships for the next round. It never stops, but in some ways that is the fun part of it to meet new people to share your startup's story.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
