About GeekByte.
GeekByte is a technology advisory practice for PE-backed portfolio companies, led by Grant Howe. The practice serves PE sponsors, portfolio-company boards, and the CEOs running through DD-to-exit. Three offerings — Board Advisory, Growth Advisory, and the SDD methodology delivered inside Growth Advisory engagements — cover the four stages of the deal: diligence, post-close, engineering implementation, and exit prep.
The practice was founded on 25+ years of operator experience: multiple successful PE exits as a CTO and SVP of R&D, 27+ M&A integrations, and 15 cloud migrations. Most engagements start with a sponsor referral and run with the portfolio CEO or the board.
Grant Howe
Founder & Managing Partner, GeekByte LLC
Grant Howe leads GeekByte. He currently serves as an independent director on a PE-backed portfolio company, advises sponsors and CEOs across DD-to-exit engagements, and runs the practice's growth-advisory work. Recent engagements have run as one continuous arc — sitting with the deal team during diligence, drafting the value-creation plan that goes to IC, then executing it below the line through close, the 100-day window, and the path to exit.
The operator history behind the practice comes from two principal roles. As Global CTO at a PE-backed software company, he led technology through two successful PE exits, integrated 27+ add-on acquisitions, and migrated 15 on-premise products to cloud SaaS while the business grew from $27M to $85M in ARR through both organic and inorganic lanes. Prior to that, as SVP of R&D at Sage, he led the cloud migration of the flagship on-premise Windows product and supported a successful exit to Accel-KKR.
The technical foundation is hands-on: enterprise-grade security platforms, performance monitoring systems, and USPS-certified software built earlier in his career. That background is why board and advisory engagements where someone at the table can actually read an architecture diagram tend to route to the practice — and why sponsors keep the firm in the rotation when technology risk is on the table. Cross-sector experience spans manufacturing, distribution, field service, nonprofit, government, and enterprise software. Recent advisory work has increasingly involved AI-adoption decisions at the portfolio-company level — build-versus-buy calls, vendor concentration risk, and the gap between AI demos and production-grade systems.

Three Things the CEOs Have Named.
Not positioning GeekByte wrote for itself — observations from CEOs after the engagement. These three come up consistently.
A Peer Who Has Run the Thing
Grant has been the CTO during due diligence, during integration, during the run-up to sale — across multiple successful exits. When a CEO's board presses on technology risk or a sponsor asks about AI, there is no translation step. The shape of the conversation is already known, and the advisor steps into it at the CEO's side, on the CEO's timing. Board-advisor work elsewhere is why sponsors recognize the name — but it is the operator history that makes the partnership work.
Pattern Recognition from the Seat You're In
27+ M&A integrations, 15 cloud migrations, multiple exits. That history means the practice can tell a CEO quickly which open items will actually bite at exit and which are noise, which integration approaches stall and which land, and which AI bets look strategic but are really expensive distraction. Answers at the speed of conversation — not weeks of research per question and not a framework delivered to your team.
Execution Credibility, Not Slideware
Post-close execution is where most advisors lose the thread — the board deck is clean, the plan is reasonable, and the work doesn't happen. Growth-advisor engagements are structured around closed items, not frameworks: DD findings with documented remediation, 100-day plans with actual outcomes, and integrations that hit synergy targets because someone experienced is in the work with the team.
What the Practice Delivers for PE Partners
Every engagement is focused on one thing: protecting and accelerating your investment returns.
- Exit Readiness: Technology documentation and architecture that withstands buyer due diligence
- Value Creation: Cloud migration, platform modernization, and operational efficiency that drives EBITDA
- Risk Mitigation: Honest technical assessments that identify issues before they impact multiples
- Integration Velocity: Proven playbooks for M&A technology consolidation that accelerate synergies
- Team Assessment: Objective evaluation of technology leadership to inform hiring and retention decisions
