Should your startup opt for SAFEs or convertible notes on your next funding round? This Houston expert weighs in. Photo via Getty Images

As both a founder and occasional early-stage investor in the Houston ecosystem, I've seen firsthand the opportunities and challenges surrounding seed funding for local startups. This critical first fundraising round sets the trajectory, but navigating the landscape can be tricky, especially for first time founders who may not be familiar with the lingo.

One key dynamic is choosing the right deal structure — SAFEs (Simple Agreement for Future Equity) vs. convertible notes are the most common vehicles early stage startups use to raise capital and are far more founder-friendly than a priced round.

Let's start first with what the have in common:

  • Both allow you to defer setting a valuation for your company until a later (likely priced) round, which is useful in early stages or pre-revenue companies
  • Both are cheaper and faster to execute than a priced round, which cash-strapped early stage founders like
  • Both can have terms like valuation cap, discount, conversion event, and pro rata rights.
  • Both are less attractive to investors seeking immediate equity (especially important if starting the QSBS clock is part of your investors strategy or if the investor is newer to startup investing)
  • Both can create messy cap tables and the potential for a lot of dilution for the founders (and investors) if they are used for multiple raises (especially with different terms)

While as you can see they have similarities, they have some important differences. Let's dig in on these next:

SAFEs:

  • Created by Y Combinator in 2013, the intent was to create a simplified, founder friendly agreement as an alternative to the convertible note
  • Is an agreement for future equity for the investor at a conversion event (priced round or liquidation event) which converts automatically.
  • It's not a debt instrument and does not accrue interest or have a maturity date.
  • Generally have much lower upfront legal costs and faster to execute

Convertible Notes:

  • A debt agreement that converts to equity at a later date (or conversion event like a priced round)
  • Accrues interest (usually 2 to 8 percent) and has a maturity date by which the note must either be repaid or convert to equity. If you reach your maturity date before raising a qualifying round, you can often renegotiate to extend the maturity date or convert the note, though be prepared to agree to higher interest rates, additional warrants, or more favorable conversion terms.
  • More complex and take longer to finalize due to non-standard terms resulting in higher legal and administrative costs

It's worth reiterating that in both cases, raising multiple rounds can lead to headaches in the form of complex cap tables, lots of dilution, and higher legal expenses to determine conversion terms. If your rounds have different terms on discounts and valuation caps (likely) it can cause confusion around equity and cap table structure, and leave you (the founder) not sure how much equity you will have until the conversion occurs.

In my last startup, our legal counsel — one of the big dogs in this space for what it's worth — strongly advised us to only do one SAFE round to prevent this.

Why do some investors tend to prefer convertible notes?

There are a few reasons why some investors, particularly angel investors from developing startup ecosystems (like Houston), prefer convertible notes to SAFEs.

  • Because they are structured as debt, note holders have a higher priority than equity investors in recovering their investment if the company fails or is liquidated. This means they would get paid after other creditors (like loans or credit cards) but before equity investors, increasing the likelihood of getting some of their money back.
  • The interest terms protect investors if the founder takes a long time to raise a priced funding round. As time passes, interest accumulates, increasing the investor's potential return. This usually results in the investor receiving a larger equity stake when the note converts. However, if the investor chooses to call in the note instead, the accrued interest would increase the amount of money owed, similar to a traditional loan
  • More defined conversion triggers (including a maturity date) gives investors more control and transparency on when and how their investment will convert.
  • Can negotiate more favorable terms than the standard SAFE agreement, including having both a valuation cap and a discount (uncommon on a SAFE, which usually only has one or the other), interest rates, and amendment clauses to protect them from term revisions on earlier investors by future investors (called a cram-down), etc.
We'll go over what the various terms in these agreements are and what to look out for in a future article

How to choose:

  • Consider your startup's stage and valuation certainty — really uncertain or super early? Either of these instruments are preferable to a priced round as you can defer the valuation discussion
  • Assess investor preferences in your network — often the deciding factor if you don't have a lot of leverage; most local angels prefer c-notes because they see them as less risky though SAFEs are becoming more common with investors in tech hubs like Silicon Valley
  • Evaluate your timeline and budget for legal costs — as I mentioned, SAFEs are way less expensive to execute (though still be prepared to spend some cash).
  • Align the vehicle with your specific goals and growth trajectory

There's no one-size-fits-all solution, so it's crucial to weigh these factors carefully.

The meanings of these round terms like "seed" are flexible, and the average seed funding amount has increased significantly over the past decade, reaching $3.5 million as of January 2024. This trend underscores the importance of choosing the right funding vehicle and approach.

Looking ahead, I'm bullish on Houston's growing startup ecosystem flourishing further. Expect more capital formation from recycled wins, especially once recently minted unicorns like High Radius, Cart.com, Solugen, and Axiom Space exit and infuse the ecosystem with fresh and hungry angels, new platforms beyond traditional venture models, and evolving founder demographics bringing fresh perspectives.

Houston falls from top 50 in global ranking of 'World's Best Cities'

Rankings & Reports

Houston is no longer one of the top 50 best cities in the world, according to a prestigious annual report by Canada-based real estate and tourism marketing firm Resonance Consultancy.

The newest "World's Best Cities" list dropped Houston from No. 40 last year to No. 58 for 2026.

The experts at Resonance Consultancy annually compare the world's top 100 cities with metropolitan populations of at least 1 million residents or more based on the relative qualities of livability, "lovability," and prosperity. The firm additionally collaborated with AI software company AlphaGeo to determine each city's "exposure to risk, adaptation capacity," and resilience to change.

The No. 1 best city in the world is London, with New York (No. 2), Paris (No. 3), Tokyo (No. 4), and Madrid (No. 5) rounding out the top five in 2026.

Houston at least didn't rank as poorly as it did in 2023, when the city surprisingly plummeted as the 66th best city in the world. In 2022, Houston ranked 42nd on the list.

Despite dropping 18 places, Resonance Consultancy maintains that Houston "keeps defying gravity" and is a "coveted hometown for the best and brightest on earth."

The report cited the Houston metro's ever-growing population, its relatively low median home values ($265,000 in 2024), and its expanding job market as top reasons for why the city shouldn't be overlooked.

"Chevron’s shift of its headquarters from California to Houston, backed by $100 million in renovations, crowns relocations drawn by record 2024 Port Houston throughput of more than four million containers and a projected 71,000 new jobs in 2025," the report said.

The report also draws attention to the city's diversity, spanning from the upcoming grand opening of the long-awaited Ismaili Center, to the transformation of several industrial buildings near Memorial City Mall into a mixed-use development called Greenside.

"West Houston’s Greenside will convert 35,000 square feet of warehouses into a retail, restaurant and community hub around a one-acre park by 2026, while America’s inaugural Ismaili Center remains on schedule for later this year," the report said. "The gathering place for the community and home for programs promoting understanding of Islam and the Ismaili community is another cultural jewel for the country’s most proudly diverse major city."

In Resonance Consultancy's separate list ranking "America's Best Cities," Houston fell out of the top 10 and currently ranks as the 13th best U.S. city.

Elsewhere in Texas, Austin and Dallas also saw major declines in their standings for 2026. Austin plummeted from No. 53 last year to No. 87 for 2026, and Dallas fell from No. 53 to No. 78.

"In this decade of rapid transformation, the world’s cities are confronting challenges head‑on, from climate resilience and aging infrastructure to equitable growth," the report said. "The pandemic, long forgotten but still a sage oracle, exposed foundational weaknesses – from health‑care capacity to housing affordability. Yet, true to their dynamic nature, the leading cities are not merely recovering, but setting the pace, defining new paradigms of innovation, sustainability and everyday livability."

Waymo self-driving robotaxis will launch in Houston in 2026

Coming Soon

Houston just cleared a major lane to the future. Waymo has announced the official launch of its self-driving robotaxi service in the Bayou City, beginning with employee-only operations this fall ahead of a public launch in early 2026.

The full rollout will include three Texas cities, Houston, Dallas, and San Antonio, along with Miami and Orlando, Florida. Currently, the company operates in the San Francisco Bay Area, Phoenix, and Los Angeles, with service available in Austin and Atlanta through Uber.

Before letting its technology loose on a city, Waymo first tests the routes with human drivers. Once each locale is mapped, the cars can begin driving independently. Unique situations are flagged by specialists, and engineers evaluate performance in virtual replicas of each city.

“Waymo’s quickly entering a number of new cities in the U.S. and around the world, and our approach to every new city is consistent,” explained the announcement. “We compare our driving performance against a proven baseline to validate the performance of the Waymo Driver and identify any unique local characteristics.”

The launch puts Waymo ahead of Tesla. Elon Musk’s Austin-based carmaker has made a lot of hullabaloo about autonomy being the future of the company, but has yet to launch its service on a wide scale.

Waymo started testing San Antonio’s roadways in May as part of a multi-city “road trip,” which also included Houston. The company says its measured approach to launches helps alleviate local concern over safety and other issues.

“The future of transportation is accelerating, and we are driving it forward with a commitment to quality and safety,” Waymo wrote. “Our rigorous process of continuous iteration, validation, and local engagement ensures that we put communities first as we expand.”
