Feature Sprints · App Builds · Embedded Dev Teams
Most dev shops give you engineers. You still have to manage them, spec the features, and figure out if what gets built is moving your metrics. We give you the full team.
Fixed-price sprints · Dev team from $45/hr · No minimum commitment
Three Ways to Engage
From scoped call to live feature in 6–8 weeks. Fixed price, no billing surprises.
Strategy, specs, and product judgment in the same team. No coordination overhead, no gap between what gets built and what was needed.
Every sprint tied to a measurable result. You know from week one whether what shipped is working.

Most agencies hand you engineers. We bring the full stack: product strategy, analytics instrumentation, design, AI, development, and business operations — all running AI-first workflows that ship weekly, not quarterly.
Product strategy is the starting point — not the afterthought. We classify your product across 10 structural dimensions (value delivery model, growth motion, buyer-user gap, activation complexity) to identify which strategies are structurally viable for your business. Every build decision flows from this analysis.
Strategy that matches your product's structural reality — not borrowed playbooks
Slack's PLG worked because of Slack's structural DNA. Copying the playbook without the structure is how teams spend quarters on strategies their product was never built to support.
We instrument everything before it ships. PostHog, Amplitude, Mixpanel — we set up the tracking, build the dashboards, and run the statistical tests. When an experiment finishes, you know whether it worked within days, not quarters. Every metric is tied to a business outcome.
You know what's working within days — not when someone checks a quarterly report
We run 8 experiments per month where most teams run 1-2. That's 8x the learning compressed into the same calendar month.
Design decisions that can't be tied to a metric aren't design decisions — they're opinions with a budget. We design onboarding flows, activation paths, conversion pages, and product UX with measurement built in from the start. Every design choice has a hypothesis behind it and a way to validate it.
Every screen ships with a hypothesis — and gets validated against real data
We don't hand you mockups and walk away. We design, build, instrument, ship, and measure — then iterate based on what the data says.
We run AI-first workflows internally — Claude for code generation, automated testing, self-healing error triage, AI-powered code review. This isn't theoretical. We deploy 3-8 production changes per day using the same harness engineering model we implement for clients. AI as the primary builder, humans as architects and validators.
AI-first means redesigning the process — not bolting ChatGPT onto your existing workflow
AI-assisted gets you 10-20% faster. AI-first — redesigning planning, building, testing, and deployment around AI — gets you 10x faster.
We ship weekly, not quarterly. Monorepo architecture, automated CI/CD, feature flags for gradual rollout, and AI-generated test suites. Every feature goes through a 6-phase pipeline: verify, build dev, test dev, deploy prod, test prod, release. Your team inherits this velocity when we hand over.
Your org ships weekly — because we restructure for velocity, not just add engineers
The bottleneck is almost never "we need more developers." It's fragmented code, manual testing, missing feature flags, and synchronous decision-making. We fix the system, not just the symptoms.
Growth strategy without operational execution is a slide deck. We restructure the operational layer — how decisions get made, how data flows between teams, how experiments get approved and shipped — so your organisation can actually execute at the speed your strategy requires.
Your org stops being the bottleneck between strategy and execution
Right now: 1 experiment/month = 1 month of learning. After restructuring: 8 experiments/month = 8 months of learning compressed into one.
Why Features Stay in the Backlog
Most founders and product teams hit the same wall: the brief is in someone’s head, the spec never quite gets written, and the feature that keeps getting bumped is still six months away. Here’s what that looks like.
"You hired a dev agency. Now you spend half your time managing them instead of running your company."
Dev shops deliver code. They don't deliver product thinking. Every spec gap, every edge case, every "is this what you meant?" costs you time and sprint velocity. We bring the PM and the product specialist — so you don't have to be them.
"The brief is in your head. Every time you try to write it down it turns into a 40-page document nobody reads."
We start with a 20-minute scoping call. We write the spec. We own the delivery. You review the milestones and approve the output — not the process.
"Your internal team has a roadmap. There's a feature that keeps getting bumped because they're stretched."
The embedded team model lets us run parallel to your internal team — picking up the features that keep getting pushed, without disrupting what's already in progress.
"The feature shipped. You have no idea if it's working."
Every sprint we run includes instrumentation. Not as an afterthought — as part of the spec. You can see immediately whether the feature is moving the metric it was built to move.
Three Ways to Work Together
Two sprint options with a defined deliverable and a fixed price. One embedded team option for founders who want to move fast without committing to a full build upfront.
One feature. Designed, built, and shipped in 6–8 weeks. You describe the outcome — we scope it, spec it, build it, and ship it at a fixed price.
Your feature ships on time and on budget — measured and validated immediately.
A product — or a significant rebuild — delivered to production. Scoped, staffed, and delivered at a fixed price with full documentation and handover.
Right for
A working product in production — not a prototype. Handed over with full documentation so your team can own it from launch.
Developers working alongside your team — or running the full build independently. You direct the work. We own the delivery quality and bring the product thinking.
Most founders start here, then move to fixed-price sprints once the relationship is proven.
You don't manage the PM separately from the dev. We bring both — so what gets built is what was needed, and you're not the coordination layer.
Every sprint includes instrumentation. You can see immediately if the feature is moving the metric it was built to move. No guessing a quarter later.
Design and copywriting partners embedded at sprint planning — no sourcing overhead on your side.
The same team builds AI features when you're ready. No agency-hopping when your product needs an intelligence layer added to what we've already built.
What We Cover
The biggest driver of expensive rework isn't bad code — it's a brief that was never quite right. We run a structured scoping call before anything gets estimated. You leave knowing exactly what's being built, why, and what success looks like — before you commit to a single dollar.
A clear scope before a line of code is written
Most sprints go wrong at the brief. We fix that first — so what gets built is what was needed, not what was easiest to estimate.
Developers build what the spec says. If the spec is vague, the output is vague. We write the feature spec — user flows, edge cases, acceptance criteria — so your team isn't making judgment calls in the middle of a sprint that should have been made at the start.
A spec that prevents rework — not one that causes it
A week of spec work prevents three weeks of rework. We write it, own it, and don't start the sprint until you've approved it.
Milestone-based delivery means you never have a big reveal at the end. Working code at each stage. You review it, you approve it, and the next stage starts from a foundation you've already seen. No surprises. No "that's not what I meant" six weeks in.
Features that ship on time because the spec was right
Delivery quality is a function of how well the sprint was set up. We invest in the setup — so the build runs clean.
A feature that ships without measurement is a feature you can't defend. We build analytics instrumentation into every sprint — not as an afterthought, but as part of the spec. You can see from day one whether what shipped is moving the metric it was built to move.
You know from launch whether the feature is working
Most teams add analytics three months after launch when someone asks if the feature worked. We add it to the spec on day one.
Your internal team has a roadmap and a backlog that keeps growing. The embedded team model lets us run parallel — picking up the features that keep getting pushed, without disrupting what's already in progress. Product management hours included. You direct the work, not the team.
A parallel build lane that doesn't disrupt your internal team
Most founders start here — one feature, one sprint, see how the relationship works — before moving to a fixed-price build.
When we're done, your team owns it. Not just the code — the documentation, the instrumentation, the monitoring setup, and a walkthrough session so nobody is dependent on us to keep it running. Handover is a deliverable, not a formality.
Your team owns it from day one — no dependency on us
We build to hand over, not to retain. Documentation and monitoring are part of every sprint by default — so you're never calling us to fix something you don't understand.
More devs without a PM means you ship faster — and ship the wrong things.
The dev shop model gives you execution speed on whatever the brief says. The problem is the brief — who writes it, who owns it, who catches the edge cases before they become expensive rework.
We connect the build to the outcome. What ships is what was needed — and you can measure it immediately.
From Call to Shipped
You tell us what needs to be built. We identify the scope, estimate the complexity, and give you a fixed price or an hourly structure — before you commit to anything.
We write the spec, design the flows, and build against your actual tech stack. Regular milestone reviews. You approve the output at each stage — you're never surprised by what arrives.
Live in production with measurement in place. You can see immediately if the feature is working. If you want to keep going, the team is already up to speed — no ramp-up for the next sprint.
Who This Is For
What’s in Every Engagement
Product management, analytics instrumentation, and a working handover come with every engagement by default. You don’t manage the team — you review the milestones and approve the output.
One feature. Scoped, built, and shipped in 6–8 weeks at a fixed price. You describe the outcome — we spec it, build it, and ship it.
A full product — net new app, MVP, or major rebuild — delivered to production over 10–14 weeks at a fixed price.
Developers working alongside your team, or running the full build independently. Flexible — pause or stop anytime, no minimum.
What We Commit To
These commitments are written into every engagement before work starts — not assurances we offer after something goes wrong.
Fixed price on sprints, agreed before work starts. Every invoice matches a milestone you approved. No billing surprises, no open-ended scope.
Product management and project oversight included in every build. You don't need to hire a PM or manage the team yourself — that's part of what we deliver.
What we scope, we ship. Milestone-based delivery with working, reviewable code at every stage. No big reveal at the end — you see progress throughout.
Every sprint ships with instrumentation live. You can see immediately whether the feature is working — not weeks later when someone thinks to check.
Who You’re Working With
No account managers, no junior handoffs. Jake runs every sprint directly — from the scoping call through to production handover — so there’s one person accountable for the outcome.
I'm Jake. 8+ years in B2B SaaS product and growth — not as a developer shipping features, but as the person accountable for whether those features moved the business. I've scoped, staffed, and delivered product sprints across healthtech, adtech, edtech, and B2B tools. I know the difference between a well-built spec and one that creates expensive rework at week four.
I started ProductQuant because I kept seeing the same problem: founders and PMs managing dev shops with no product thinking in the team. Engineers shipped exactly what the brief said. The brief was wrong. Nobody caught it until the feature was live and the metrics didn't move.
Common Questions
Tell us what you need built. We map the complexity, give you a fixed price or hourly structure, and tell you exactly how long it takes — before you commit to anything.
No pitch. No questionnaire. Just a clear scope and a price before you decide.
