VENTISEI

Stockholm MMXXVI

We design and ship product systems for founders and operators who want one accountable partner across strategy, design, and engineering.

About

Shape
Six- to twelve-week engagements. Strategy, design and engineering as one team.
Pricing
Fixed-fee per phase. The deliverable is the decision and the build, not the hours.
Out of scope
Brand work alone, M&A theatre, growth hacking, AI features without a product reason.
Stack
TypeScript, React, React Native, Cloudflare, Supabase, Postgres, OpenAI, Anthropic.
For
Founders and product leaders who can frame the question and want a second pair of hands to ship the answer.

Six things a product needs to keep working after launch.

What survives contact with real users.

Point of view

A defensible refusal. Knowing what the product will not do is what keeps the roadmap from rotting into a feature buffet.

Closed loop

Interface, data, operations and distribution reinforce one another. Most teams ship one of those four and call it done.

Distribution inside

Growth lives in the behavior, not in a campaign deck. If acquisition only works through paid, the product is fragile.

Trust layer

Honest limits, reversible mistakes, audit trail. The cost of an opaque system is paid in churn and legal review.

Operational spine

The back office that supports the surface: support, billing, observability, escalation. Beauty without spine collapses on day 30.

Tradeoff discipline

Every feature kicks something else off the surface. Teams that can name what they cut ship faster than teams that can't.

Where AI actually pays back inside a product.

Decisions, not demos.

Decision compression

Cut the distance between signal and action. Don't replace the human accountable for the call — give them sharper inputs, faster.

Memory with edges

What the system remembers is product. What it forgets is policy. Most AI failures live at this boundary.

Reversible automation

Every automated action needs a clear undo path and a visible owner. Otherwise mistakes scale faster than value.

Latency budget

If the AI step adds three seconds, redesign the flow. Slow magic feels like broken software, no matter the model quality.

Cost per outcome

Track inference cost against the unit economic it changes. Models without a cost line in the P&L become quietly unsustainable.

Measured reality

Demo velocity is not durable change. The only honest metric is whether downstream work got faster, clearer, or cheaper.

One engagement, summarised.

A European industrial group needed an internal platform to replace a sprawl of shared drives, Confluence pages and spreadsheets that thousands of people touched every day.

Window
Twelve weeks.
Built
One contextual surface that stitches engineering specs, quality data and ERP records into a single working view.
Replaced
Six duplicated reference docs, four manual handoff steps, two parallel tracking spreadsheets.
Outcome
Adopted across R&D, manufacturing and supply chain. Still in use.

What lives here.

Products built and kept inside the studio.

Industrial documentation that stops being a graveyard. More when it ships.
