Eric Calderon's Second Act: Building a $25M Oil & Gas TIC Platform in Houston

The Setup Eric Calderon found entrepreneurship through acquisition at Harvard Business School about a decade ago. He walked in expecting to chase a corporate executive track. A class with Rick Ruback and Royce Yudkoff flipped the script. He ran a traditional search fund in Houston with Ruback and Yudkoff as investors, bought a business, operated it, and exited successfully. That exit gave him two things most first-time searchers lack: proof he could run a company, and capital plus credibility to raise patient money for round two. TXE Partners is that round two. It sits in testing, inspection, and calibration (TIC) serving oil & gas customers. Most searchers actively avoid oil & gas. Cyclicality scares off committee-driven capital. Calderon walked straight into the sector that other buyers wouldn't touch, in the city (Houston) where the customer base lives. The Deal Calderon isn't doing one big platform acquisition. He's assembling a sector company out of small bolt-ons with roughly $1M in seller's discretionary earnings each. The aggregate today: approximately $25M in revenue across the divisions. Capital structure is deliberately patient. He raised from long-term committed investors rather than running a typical SBA or independent-sponsor deal-by-deal raise. Patient capital matters here because oil & gas TIC cycles with rig counts and capex budgets; short-duration debt against cyclical EBITDA is how searchers get carried out. Operating Moves Calderon rejects the 'holdco' label that every Twitter searcher is flying in 2025. His framing is sharper: TXE is a sector-specific operating company, and the acquired shops are divisions, not portfolio companies. The distinction drives real decisions: - Shared services sit at the TXE level where scale pays (finance, sales coordination, compliance, customer relationships with the majors). - Field operations stay decentralized because calibration and inspection work is tribal-knowledge-heavy and technician-led. - Acquisitions are picked to fill capability gaps in the enterprise offering, not to stack EBITDA for arbitrage. That is closer to how a strategic acquirer thinks than how a holdco thinks. A holdco optimizes for diversification. A sector operator optimizes for cross-sell, utilization, and enterprise contracts with the same buyer. Operating Lessons - Second searches compound. Industry knowledge, investor relationships, and operator reps from deal one are why deal two can be a multi-acquisition platform instead of another single shot. - Pick the sector other searchers won't touch. Oil & gas is 'off the list' for most ETA capital. That's exactly why TIC bolt-ons were available at reasonable SDE multiples in Houston. - Raise patient capital before you need it. Committed long-term investors let you buy through the cycle instead of getting margin-called by a lender when rig counts dip. - Bolt-on at ~$1M SDE. Small enough that seller expectations are reasonable, big enough that one integration doesn't blow up your week. Stacking ten of those is a real company; stacking ten $200K SDE shops is a job. - Language shapes the operating model. Calling divisions 'divisions' (not 'portcos') tells your team, your customers, and yourself that this is one company, not a pile. **Where...
