Top 7 Texas Software Investors: Angel Networks and VC Firms 2026

Austin, Dallas, San Antonio, or maybe Houston. You must have heard these names as the future hubs of tech innovation. But, all these names lead back to one single region... Texas!

The most active software investors in Texas are S3 Ventures, Capstreet, Clovis Point Capital, Sallyport Investments, the Central Texas Angel Network, the Houston Angel Network, and Alamo Angels. Three are angel networks whose members write early checks together. Four are firms that lead seed, growth, and buyout rounds in business software.

Home to 30+ unicorns, Texas has emerged as one of the biggest startup landscapes worldwide. Every year, hundreds of startups close funding deals that are worth billions of dollars. And the best part?

Your startup could also do the same, having a go-to list of some of the most active investors in the state.

So, to help you pitch to the right people, we have come up with the following list of top angel investors in Texas and the firms that fund software startups here. Angel Match currently tracks 3,700+ investors headquartered in Texas and 40,000+ investors who back software worldwide.

Who Are the Top Software Investors in Texas?

S3 Ventures

• Focused Sectors: Business software, software applications, IT infrastructure, developer tools and platforms, hardware, healthcare technology

• Based In: Austin, Texas

• Stages: Seed, Series A, Series B

Founded in 2005, S3 Ventures describes itself as the largest and longest-serving venture capital firm born in Texas, with more than $1 billion in assets under management. In December 2025 the firm announced its eighth fund at $250 million and marked its twentieth year, with 40+ active portfolio companies and an entirely Austin-based team of 12.

S3 is unusual in that it is backed by a single limited partner, a philanthropic family foundation. That structure means the team is not raising a new fund every two years, which lets it hold positions longer than a typical firm can.

The firm leads seed, Series A, and Series B rounds with initial checks of $500,000 to $15 million and the ability to invest $25 million or more over the life of a company. Nearly half its active companies are in Texas.

Capstreet (Neil Kallmeyer)

• Focused Sectors: Lower middle market software, tech-enabled services, industrial business services

• Based In: Houston, Texas

• Notable Investments: PCS Software, Surgical Notes, Hart InterCivic, Ontellus, symplr

Capstreet was founded in 1990 and invests in lower middle market software, tech-enabled services, and industrial business services companies. Neil Kallmeyer is a Managing Partner at the firm and a member of its investment committee.

Kallmeyer has more than 20 years of private equity and investment banking experience. He has worked with prior Capstreet portfolio companies including Switch and Data, Warren Alloy, Worldwise, and symplr, and currently sits on the boards of Griffin Dewatering, Ontellus, MerchantWise Solutions, Incentive Solutions, PCS Software, and Surgical Notes.

Before joining Capstreet he worked at Wachovia Securities (formerly First Union Securities / Bowles Hollowell Conner) in Charlotte and at Chemical Securities, now part of JP Morgan, in New York and Australia. He has served as President of the Houston Private Equity Association and on the board of the Houston chapter of the Association for Corporate Growth.

Clovis Point Capital

• Focused Sectors: Enterprise software, technology-enabled business services

• Based In: Houston, Texas

• Notable Investments: Decision Logic

Clovis Point Capital is a Houston-based lower middle market fund that invests in enterprise software and technology-enabled business services companies. The firm is a relationship-driven investor rather than a high-volume one, and it takes board seats at the companies it backs.

In April 2025 Clovis Point led a growth investment in Decision Logic, a back-office management software platform for multi-unit restaurant operators. Chris Joseph, Brian Bergeron, and Tyron Stading joined the Decision Logic board on the firm's behalf.

If your company is past the experiment stage and has real revenue from software, this is the profile of investor worth studying. Clovis Point is a growth and control investor, not a first-check writer.

Sallyport Investments (Kyle Bethancourt)

• Focused Sectors: Energy, specialty finance, logistics, energy data software

• Based In: Houston, Texas

• Notable Investments: Validere, VRGL, EnGoPlanet, Sallyport Commercial Finance

Kyle Bethancourt is a co-founder and Managing Partner of Sallyport Investments, a Houston private investment firm focused on energy, specialty finance, and logistics. He is responsible for deal sourcing, relationships, and new investments.

His software exposure comes through the energy and fintech stack rather than consumer apps. He sits on the board of Validere, an energy supply chain data platform, and of VRGL, a financial software company, and has also served on the boards of EnGoPlanet Energy Solutions and Sallyport Commercial Finance.

Before Sallyport, Bethancourt was a Vice President at Blackstone's credit arm, GSO Capital Partners, where he focused on exploration and production investments in the Permian basin and the Utica shale. Prior to that he was at D. E. Shaw & Co., where he invested in renewable and traditional power projects, and earlier at El Paso Corporation and Merrill Lynch. He holds a BBA from Texas A&M and an MBA from Wharton.

Central Texas Angel Network (CTAN)

• Focused Sectors: Sector agnostic, with heavy software, health tech, and industrial technology deal flow

• Based In: Austin, Texas

• Members: 140 accredited investors

Founded in 2006, CTAN is the longest-running angel network in Austin and one of the most active in the country. Its members have invested $142.4 million in 233 companies since inception, and the group runs a sidecar fund alongside direct member investments.

CTAN is a nonprofit, member-based organization with a full-time executive director and a volunteer board. Members drive their own due diligence, which means a real diligence process rather than a rubber stamp. It is a member of the Angel Capital Association.

In October 2025 CTAN began accepting capped post-money SAFE notes in addition to equity and convertible notes, which matters if you have already papered your round as a SAFE. Applications are submitted through the group's website, then move through member voting, a pitch night, and diligence.

Houston Angel Network (HAN)

• Focused Sectors: Early-stage technology, energy transition, life science, enterprise software

• Based In: Houston, Texas

• Members: 100+ accredited investors, plus institutional members

The Houston Angel Network is the oldest angel group in Texas, founded in 2001. Its members have invested more than $100 million across more than 400 deals.

A typical HAN member is an accredited investor who wants to provide both capital and coaching to early-stage companies. The network also has institutional members, including seed funds, accelerators, and universities, which is useful if you want one conversation to open several doors at once.

HAN is a nonprofit and does not charge fees to entrepreneurs. Its revenue comes from membership dues and sponsorships. Alongside its investment meetings it runs educational programming, including an Angel Bootcamp co-sponsored with Capital Factory and the Rice Alliance for Technology and Entrepreneurship.

Alamo Angels

• Based In: San Antonio, Texas

• Members: 140+ accredited investors

Alamo Angels is San Antonio's main angel network and one of the more active groups in the state.

It was originally launched with support from VelocityTX and now operates independently as a 501(c)(6) nonprofit.

The group holds monthly pitch events and runs an investment syndicate that pools member capital, with each participating member contributing a minimum of $25,000. Its national deal network sources over 300 deals a year.

Alamo Angels is a member of the Angel Capital Association and an active participant in the Alliance of Texas Angel Networks, a group of more than a dozen Texas angel organizations that share deal flow. Out-of-state companies are welcome to pitch, though the group's preference is local.

Frequently Asked Questions

How Do You Pitch Texas Investors?

Texas's startup landscape offers many opportunities, but only if you are willing to capitalize on them.

Every day, investors sit through below-average pitch decks, which means you have to come up with something that catches their attention. So instead of facing a blunt "no" because of a bad pitch, here are three tips that will help.

• Talk about the specific problem. A good pitch deck should clearly define your problem and demonstrate how your solution uniquely solves it. It helps to read through a few decks that actually raised, and our pitch deck database is a good place to start.

• Discuss traction early. Whether it is user growth, revenue, or a solid proof of concept, showing traction helps investors trust that your business model works and has the potential to scale.

• Know your numbers. Be prepared to explain your revenue model, market size, margins, and potential profitability in detail. Understand which of the startup stages you are actually in, because pitching a Series A story on seed-stage traction is an easy way to lose the room.
