You don't always need a technical co-founder. Sometimes you need a senior developer who ships.
The 'I need a technical co-founder' problem is often actually a 'I need someone who can build my MVP and advise on technical decisions' problem. A fixed-price senior developer solves the second problem without the co-founder search, equity negotiation, and founder-relationship risk of the first. RCB Software is that developer. Fixed scope, fixed price.
You're a non-technical founder who's been told you need a technical co-founder. You've been searching for 6 months and haven't found the right person.
The technical co-founder search is one of the most time-consuming and frustrating founder experiences. The people you want as technical co-founders are senior developers who have shipped products before, understand the startup context, and can make sound architectural decisions under the ambiguity of early-stage product development. These people are rare, they have options, and they're not browsing co-founder matching platforms.
The equity conversation is also genuinely complex: a technical co-founder who joins before product-market fit is taking significant risk and reasonably expects significant equity (15–30% is common). Post-PMF, the same person might command 5–10%. The founder who is pre-PMF but has a strong hypothesis is in a difficult negotiation position — offering enough equity to attract a senior technical person while not giving away the company for a product that might not work.
The distinction that matters: what a non-technical founder actually needs is someone who can (1) advise on what to build and in what order, (2) make the architectural decisions that determine whether the codebase can scale post-validation, (3) build the product to a production standard, and (4) hand off to an in-house engineering team when the startup has the revenue to justify it. These are the co-founder functions that a fixed-price senior developer provides — without equity, without the co-founder relationship, and without the risk of the wrong co-founder who can't be fired.
A production MVP built by a senior developer who provides the technical judgement and product delivery you were looking for in a co-founder — without the equity, the co-founder dynamic, or the hiring process.
Architecture advisory
Technology selection recommendations (what stack to use and why), build vs buy decisions (when to use a third-party service and when to build custom), and the infrastructure decisions that determine long-term scalability. Explained in business terms, not technical jargon.
Product scope guidance
The MVP scope definition process that separates what needs to be in the first version from what can be deferred. Most non-technical founders over-scope the initial build; the specification process is the discipline that keeps the MVP achievable.
Production application delivery
The full MVP, built to production standards: real auth, real database, real payments if applicable, deployed to production, accessible at a real domain. Not a prototype — a product you can sell.
Post-launch architectural guidance
After delivery, a consultation on the post-launch technical roadmap: what to build next, what architectural investments to make before the Series A, and how to think about hiring technical talent in-house.
Handoff documentation
Architecture documentation that makes an in-house technical hire or a future contractor productive from day one. The code you own is documented code.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
A non-technical founder entering a co-founder search has no way to evaluate the downside. Fixed scope, fixed price means the commitment is finite and the deliverable is defined before you sign.

Questions, answered.
If you're building a deeply technical product where the competitive differentiation is the technology itself (novel ML infrastructure, proprietary hardware integration, research-driven software), a technical co-founder who is also a domain expert may be essential. For most SaaS, marketplace, and consumer products, the competitive differentiation is the product and the go-to-market — not the technology implementation. In those cases, building with a fixed-price developer and hiring a senior engineering lead post-PMF is the more efficient path.
Yes — answering technical questions from investors during a seed raise is a common engagement addition. Architecture explanation, tech stack rationale, scalability roadmap, and the "what would break at 10x current load" question — these are answerable with the production application and its documentation.
The codebase is handed off with documentation. The technology choices (Next.js, TypeScript, Postgres, Clerk) are standard — the in-house hire will know the stack. The architecture documentation explains the decisions. A good engineering hire can be productive within 2 weeks.
Advisory retainer engagements (a defined number of hours per month for ongoing architectural questions and technical review) are available as post-launch add-ons. The scope and price are defined separately from the MVP build.
MVP build plus architectural advisory: $30k–$55k for the initial delivery. Post-launch advisory retainer: defined separately based on the scope. Fixed-price.
