Fractional CTO & Technical Advisory
Senior technical leadership and architectural execution for seed to Series A founders without the full-time executive overhead.
InferScale Labs provides fractional CTO and senior technical advisory services for seed to Series A startups. We conduct architectural audits, design scalable backend schemas in Go and PostgreSQL, optimize cloud infrastructure costs, and guide technical hiring without the full-time executive overhead.
Make the next architecture decision with confidence
We work with founders and engineering leads when the roadmap is moving faster than the team’s technical decision-making capacity. The engagement starts with your actual codebase, infrastructure, constraints, and business priorities.
A clearer technical roadmap
Identify the highest-risk architecture decisions and sequence changes around product milestones.
More deliberate engineering investment
Review cloud spend, build-versus-buy choices, reliability gaps, and hiring needs.
Senior support for your team
Get a partner for design reviews, difficult tradeoffs, and communication with stakeholders.
From requirements to a working result
- 01
Review the current system
Inspect architecture, delivery practices, incidents, and the decisions waiting on leadership.
- 02
Prioritise the tradeoffs
Agree on the risks worth addressing now and document practical options and ownership.
- 03
Guide execution
Join design and implementation reviews as the team turns decisions into shipped changes.

Fractional CTO FAQs
Direct answers to common questions about our engineering and advisory engagements.
What is the difference between a full-time and fractional CTO?
A full-time CTO is a permanent executive hire requiring substantial equity and executive salaries ($200k–$400k+). A fractional CTO from InferScale Labs gives seed to Series A founders on-demand access to high-level architectural leadership, codebase audits, and hiring vetting at a fraction of the cost, focused strictly on high-impact technical milestones.
How does InferScale Labs engage with our existing engineering team?
We embed directly into your communication channels (Slack, GitHub, Linear). We participate in architectural planning sessions, conduct senior pull request reviews, mentor lead developers, and establish automated CI/CD and testing standards without disrupting your current sprint velocity.
What is the typical retainer structure?
Our advisory engagements operate on a flexible monthly or quarterly retainer. Retainers include weekly architectural strategy calls, on-call incident advisory, pull request reviews, and infrastructure cost audits with guaranteed response SLAs.
How much cloud cost savings can we typically expect?
Most venture-backed startups we audit experience a 30% to 50% reduction in monthly cloud infrastructure spend across AWS, GCP, and Cloudflare by optimizing database connection pools, rightsizing instances, and eliminating unindexed query bottlenecks.
