Why choose Rational Partners
Battle-Hardened Operators
Former CTOs who've scaled teams through hypergrowth, made architecture decisions affecting millions of users, and managed technology crises. We bring scars, not slides.
Investment-Aligned Perspective
We understand value creation plans, EBITDA impact, and the mechanics of de-risking investments for VCs and PE. We speak your language and frame technology findings in terms that matter to investment committees.
Building Independence
Our success is measured by making you stronger, not by extending our engagement indefinitely. We transfer knowledge, build internal capability, and leave your team better equipped than we found them.
Independent & Vendor-Neutral
No technology partnerships, no service upsells, no equity interests. Our recommendations are based purely on what's right for your business, not what's profitable for ours. Only independent advice.
Proven Methodology
Our 5P framework has been refined across 100+ engagements with VC and PE-backed companies from seed to exit. Every assessment follows a structured, repeatable process so nothing gets missed.
No Consultancy Theatre
We work as part of your team, attending standups, reviewing code, and making decisions alongside your engineers. No external consultants producing reports nobody reads.
Our Services
Independent assessment of technical architecture and engineering capabilities to inform investment decisions.
Part-time strategic technology leadership for companies that need senior expertise without a full-time hire.
Practical guidance on implementing AI solutions that deliver real business value.
One-on-one mentorship for technology leaders navigating growth challenges.
