TennLabs is a two-person fractional executive consultancy. Praneeth covers technical strategy as Fractional CTO. Seetha drives execution as Fractional COO — turning ambiguity into high-performing teams and clean process.
What We Do
TennLabs covers what a single full-time hire usually can't — deep technical strategy and hands-on execution leadership.
Technical strategy, architecture reviews, and build-vs-buy calls that keep you moving fast without racking up technical debt.
Execution, program management, and process improvement — turning ambiguity into a plan your team can run on.
We diagnose why teams stall or churn and build the high-performing team you need to hit the next stage.
Leveling, interview loops, and org structure that scale with your headcount instead of fighting it.
1:1 coaching for senior engineers, tech leads, and managers — feedback, delegation, job strategy, and leading teams people want to stay on.
Clear-eyed assessments of your codebase, team, and technical risk for investors, acquirers, or your own board.
Our Process
No jargon. No fluff. Just a straightforward process that gets you from problem to solution.
We learn about your team, your technical and organizational pain points, and where leadership gaps are costing you.
We assess your architecture, team structure, and culture to identify the highest-leverage places to engage.
We scope a fractional cadence — weekly, biweekly, or project-based — tailored to what your team actually needs.
We work alongside your team on an ongoing basis, adjusting scope as your company and org evolve.
Why TennLabs
We're not a massive consultancy with cookie-cutter playbooks. We're two ex-Silicon Valley engineers turned fractional executives — one focused on technical strategy, one on execution, process, and building high-performing teams — who treat your team like our own.
One fractional CTO for technical strategy, one fractional COO for execution and team performance. Together we cover what a single hire usually can't.
We don't sell decks and frameworks. We embed with your team, make real decisions, and stay accountable to the outcomes.
Clear fractional retainers with no hidden fees or surprise invoices. You always know what you're paying for and what you're getting.
Our Team
We're two ex-Silicon Valley engineers with over 30 years of combined experience in the tech industry. We left our corporate roles to work directly with growing companies as embedded, fractional executives — the technical strategy and the execution leadership a full-time hire would normally cover, without the full-time cost.
