How We Work

A look inside a Solprime build — week by week.

The reason we ship AI-native products in 4–14 weeks isn’t because we cut corners. It’s because we’ve removed the 60% of agency time that goes into proposals, estimation revisions, scope changes, and post-launch confusion. Here’s exactly how that looks.


The three problems we designed this system to solve

Before we describe the system, here’s why it exists.

Problem 1

The discovery-phase trap

Most agencies sell you a 4–6 week “discovery” before they’ll commit to a build. That’s six weeks of slides, interviews, and revised proposals — all billable, and none of it ships software. By the time the real build starts, you’ve burned a quarter and changed your mind twice.

Problem 2

The end-of-project blackout

You sign a contract, the team disappears for 6–12 weeks, then surfaces with a “demo.” Half of what they built isn’t what you wanted. The other half works, but only on the laptop they’re demoing from. You spend the next 8 weeks negotiating change requests.

Problem 3

The launch-day handoff

The platform goes live. The team that built it disappears the same week. Three months later, something breaks at 11pm on a Friday, and you discover nobody owns the code anymore.

Our delivery model is built specifically to remove all three.

Week Zero — The Working Session

Most agencies start with a discovery phase. We start with a 90-minute working session.

What happens in 90 minutes

  • You walk us through the business problem, the constraint, and what success looks like
  • We sketch the architecture live on a shared whiteboard
  • We agree on what’s in scope and what’s deferred to v2
  • We commit to a fixed fee and a fixed timeline before the call ends

What you walk out with — within 48 hours

📄

Written scope document

Every feature, every integration, every compliance requirement.

Reference architecture diagram

The full system we’re going to build, drawn out clearly.

💰

Fixed fee

No hourly billing. No estimation revisions. One number.

Signed Statement of Work

Ready to start Monday. No ambiguity about what’s in or out.

Why this works

We’ve shipped enough AI-native products that we know the architecture for most categories — fintech lending, vendor workflows, consumer recommenders, internal platforms — within the first 30 minutes of a conversation. The 90-minute session isn’t us learning from scratch; it’s us mapping a known architecture onto your specific business.

What we charge for Week Zero

Nothing. The scoping call is free, and the scope document and architecture diagram are free. We only invoice when you sign the SOW.


The Weekly Sprint — What Monday Through Friday Looks Like

Every week of the build follows the same rhythm. After the first week, you’ll know exactly what to expect.

Monday 30-min standup

30-minute standup (synchronous)

  • Last week’s deliverables: shipped, in-progress, blocked
  • This week’s deliverables: committed to a Friday demo
  • One specific decision we need from you this week — we name it now, so you can think about it before Wednesday
Tue–Thu Async build mode

Async build mode

  • Solprime is building. You go run your business.
  • All work happens on a live Linear board you can open anytime
  • Every commit pushes to a staging environment you can access whenever you want
  • Two short async updates land in your Slack on Tuesday and Thursday — three lines each, no decks
Friday Working demo

30-minute working demo (synchronous)

  • We show you what shipped this week, working, on the staging environment
  • You give feedback live
  • We confirm what’s queued for next week, with adjustments if needed

What you literally see during the build

How we handle the two hardest parts of agency work

Scope changes mid-build

They happen. A regulator publishes new guidance. A board asks for a feature. A user-test reveals something the spec didn’t anticipate.

Our model: we lock the original SOW, but we accept up to two “scope swaps” per build at no additional cost — you take one feature out, we put another one in of equivalent complexity. Beyond two swaps, we issue a change order with a fixed fee and a new timeline. No hourly invoices. No surprises.

The 11pm Friday production incident

It happens too. Every system has incidents. The question is whether anyone owns them.

If you’ve signed our Build & Run service: we own the incident under our SLA, with a defined response time and root-cause report.

If you took only the build and not the operate service: we still answer the phone for 30 days post-launch under a warranty period. After that, your in-house team owns it — and we’re on the other end of a phone if they need help.


What happens after launch (three paths, you pick one)

Most agencies have one post-launch path: they disappear. We have three.

1

Clean handover to your in-house team

If you’ve hired engineers or are about to, we hand over a clean codebase with documentation, runbooks, and architectural decision records. We optionally help screen and interview your new hires. Then we’re done.

2

30-day post-launch warranty (default)

Included free with every build. For 30 days post-launch, we fix bugs, monitor production, and absorb the first round of user-reported issues at no charge. This is our default — nobody opts out.

∼ 1 in 6 clients
3

Build & Run — we keep operating the platform under SLA

If you don’t have an in-house team and don’t want to build one, we keep running the platform indefinitely under one of three SLA tiers ($4,000 / $8,000 / $14,000 per month, depending on response-time guarantees). We release improvements monthly. You can transfer to an in-house team anytime with 60 days’ notice and no exit fees.

The stack we work with

We have opinions, not rules. The defaults that produce the best outcomes for most AI-native builds:

Frontend
Next.js, React, TypeScript, Tailwind. React Native for mobile.
Backend
Node.js, Python where ML is heavy. PostgreSQL, Redis.
AI Layer
Claude as primary reasoning model, OpenAI as fallback. LangChain for orchestration. Pinecone or pgvector for retrieval.
Infrastructure
AWS by default, GCP on request. Vercel for frontends where appropriate.
Compliance
SOC2-aligned logging, encryption at rest and in transit, role-based access control, immutable audit trails — every build, by default.

If you have an existing stack or a strong preference, we work with what you have. Stack choices are never a deal-breaker.


What we won’t do

To save us both time on the first call, three things we explicitly don’t take on:

×

Pure marketing websites. Use Webflow or a design studio. We’re not the right team.

×

Hourly billing or open-ended retainers without a defined scope. Every engagement has a fixed scope and a fixed fee, even our consulting work.

×

Builds where AI is a marketing line, not a real architectural decision. If your spec calls for a chatbot bolted onto a static product, we’ll politely refer you elsewhere. We work on AI-native builds where the AI shapes the architecture.


The team you actually work with

Every Solprime build is led by the founder.

Not a junior account manager. Not an offshore handoff after the sales call.

You work directly with the person who scoped the project, every week, until launch. The engineering team scales up around the founder during build phase and scales back down after handover or transition to Build & Run.

We only work with 4–6 clients at a time. The model breaks if it scales beyond that.

FAQ

How quickly can we start?

Typically within 2 weeks of the working session. We hold capacity for one new build start per month. If our calendar is full, we’ll tell you in the first call and refer you to a partner we trust.

What if our scope is bigger than 14 weeks of build?

Then we’re probably not the right team for the whole thing. Our model works because every build is scoped tight enough to deliver in under 14 weeks. We can either help you phase the work into a 14-week MVP plus post-launch evolution under Build & Run, or refer you to a larger consultancy.

Do you work with non-technical founders?

This is most of our work. We handle all architecture and engineering decisions. Your job is to be clear about the business outcome you want, and available for weekly sprint reviews.

Where is the team based?

Remote, distributed across India and the US. All client-facing work happens in your time zone — your Friday demos are scheduled for your Friday afternoon, not ours.

Can we see a real Friday sprint demo from a past project?

Yes. Once you’ve signed a mutual NDA, we’ll share a recorded sprint demo from a past build (with client logos anonymized) so you can see exactly what one looks like.


Want to see what your build’s
first week would look like?

Book a 90-minute working session. We’ll sketch the architecture together, scope the build, and you’ll walk away with a written spec and a fixed fee — within 48 hours.

We take on 4–6 clients at a time so the work stays hands-on. If our calendar is full, we’ll tell you in the first call.
