A senior technical partner for founders building with AI. Honest advice on product and architecture, and someone in the room when investors ask the hard questions.
Choosing the right route
AI means a founder can now build a real product without a technical co-founder. You still need someone to tell you what not to build, check what's safe to ship and answer the hard questions when an investor's engineer looks at your code. That's the Technical Co-founder Plan: a named senior engineer, a flat annual fee and no equity required by default. If you haven't launched yet, start with the Production-Ready Audit. If you have an idea and no product, a Custom Build gets you one in 30–45 days, and we'll help you shape the scope before anything is built.

Why Dafe Software
We sit on your side of the table. Honest feedback on product, pricing, team and runway, even when it is uncomfortable.
We can advise, and we can also ship. You can move straight from strategy into a build with the same team.
We write the kind of code investors and acquirers expect to see in due diligence: clean repos, real tests, real architecture diagrams.
We help you tell the tech story, prepare technical sections of the deck, and stand in for the CTO role on diligence calls.
We will tell you what NOT to build before what to build. Cutting scope is often the fastest way to launch.
We will tell you when you need a lawyer, accountant or designer alongside us.
What we deliver
Two to 3 week engagement to test your idea with real users, refine the value proposition and decide what the MVP should be.
A focused MVP you can put in front of paying customers and investors, ready to launch in 30–45 days.
Senior technical leadership on a part time basis, covering hiring, architecture, vendor decisions and investor relations.
Technical deck sections, architecture diagrams, code audit and rehearsed diligence answers for your next round.
Landing pages, onboarding flows, analytics, lifecycle messaging and the first growth experiments.
When you need a long term technical co-founder, we can sometimes step in or help you define the role you need.
How we work
We dig into what you are actually trying to prove and to whom. Most founders find this conversation surprisingly useful.
A one page MVP brief: who is it for, what they get, what we will measure and what we will deliberately leave out.
Focused engineering and design, with weekly customer conversations baked into the plan.
Investor narrative, data room, growth experiments. We stay close while you raise your seed or Series A.
Tech stack
Start the conversation
Send a written brief and we will reply with a real plan, or book a strategy call on our calendar. Whichever is faster for you.
Project enquiry
Share a short brief. A senior founder advisor will reply within one business day to schedule a strategy call.
Common questions
Cash by default. We sometimes take a small equity component when we are deeply involved across multiple years, but the standard engagement keeps your cap table clean.
That is fine. The earlier you talk to us, the more we can save you from building the wrong thing.
Yes. We can stand in on diligence calls, write the technical part of pitch decks and answer investor questions during fundraising.
Three options: keep building with us on a retainer, hand over to a new in house team we help you hire, or wind down the engagement cleanly. Your choice.
