Technical readiness before your first raise

Before a first raise, investors ask technical questions most founders haven't had time to answer: who owns the architecture, how the product is deployed, what breaks at ten times the users, and who the first engineers are. A part-time CTO sets those foundations, gets the answers ready, and helps hire the people who will carry the product after the round.

From our experts

Selected cases from these experts’ profiles.

From pitch deck to an investable data product in months

A data startup had a pitch deck and no product. One of our CTOs built the team and the technical foundation from scratch: a data platform that collects and structures information about crypto projects for other data companies, on Go, Python, AWS and LLM APIs. Within about six months the company raised at a multi-million valuation.

Accelerator CTO-in-residence: technical due diligence for founders

Early-stage teams in an accelerator had weeks to validate ideas, build MVPs and convince investors. One of our CTOs advised more than ten of them on technical strategy and MVP scope, helped founders through investors' technical due diligence and helped recruit their first engineers.

Pre-raise technical readiness review

A founder is about to raise and expects technical questions. The expert reviews architecture, code ownership, cloud setup, security basics and team plan, the way an investor's technical advisor would.

You get

A short readiness memo with gaps to close before the round and answers the founder can give.

From idea to an investable technical foundation

A founding team had an idea and needed a product, a technical foundation and an engineering team to raise money. As founding technical lead, our expert set up all three from scratch, and the company reached investment readiness.

What to build, what to buy, and what it really costs

A founder has the idea and the money but no technical counterpart. The expert scopes the first version with them, marks what to buy off the shelf and what to build, picks a setup (a small team, coding agents, or both) and gives a realistic cost before they commit.

You get

A short scope, a build/buy list and a cost range.

Continuous delivery from day one

New products often leave deployment until the end and then struggle to launch. On new projects, one of our experts sets up the production environment first and has teams ship daily, often several times a day: infrastructure as code (Terraform/CloudFormation), automated tests up to end-to-end, linters, type checkers and security scanners, fully automated zero-downtime pipelines kept fast, and production monitoring. Clients can demo to investors at any time and launch as soon as the essentials are in.

Questions buyers ask

Do we need a full-time CTO before raising a seed round?+
Not necessarily. Many pre-seed and seed teams raise with a part-time CTO who owns the architecture, the delivery process and the hiring plan, then hand over to a full-time hire once the round closes. What investors want is someone accountable for the technology, not a title.
What do investors check in technical due diligence at seed?+
Who wrote and owns the code, how it is deployed and rolled back, security basics such as access and secrets, the main technical risks and the plan for them, and whether the team can build the roadmap they are pitching. A readiness review answers these before the first call.
What should a pre-seed startup get right on AWS first?+
Separate environments and accounts, least-privilege access, infrastructure defined as code, and cost alerts before traffic arrives. Most early AWS problems are permissions and surprise bills, not scale. A short review catches these in a day or two.
Can a startup run production software that is mostly written by AI coding agents?+
Yes, if one person owns the scope, splits the work into pieces an agent can finish, and reviews every change before it ships. One of Invental's experts runs a paid SaaS this way with two founders and no engineering team. Coding agents write most of the code; the CTO reviews it and stays responsible for what reaches customers.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert to your code or system, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
