cospree, a fractional product practice

Product leadership for B2B SaaS that has to ship real AI. Not an AI story.

Cospree is a fractional product practice. Senior, embedded, temporary by design.

Built from the inside. Led by an operator who has taken an AI product from nothing to real scale, not advised on one.

Follow the water

01 · The Channels

Teams do not lack ideas. They lack a current.

Every fork looks navigable from the bank. Most lead nowhere. The work is choosing one channel and committing the boat.

02 · The Arch

Product is masonry. Every stone bears load.

AI does not change that. It raises the price of skipping stones.

Stone arches are raised on centring: timber engineering precise enough to hold tons of stone in position until the keystone sets.

Then the centring comes down. The arch carries its own weight for centuries.

That is the engagement. We are the scaffolding. The bridge is yours.

04 · The Bank

Three ways to cross

Present when it matters. Quiet when it does not.

05 · The River

Three hundred channels. One river.

Customer noise, board pressure, engineer instinct, competitor moves. Every input is one way. The job is convergence: every tributary feeding one direction you can explain in a sentence.

  • Zero to 15,000 users on an AI product built hands on.
  • Ten years shipping B2B SaaS product across the EU and US.
  • AI shipped into products people pay for, not demos.

Fair questions

What does a fractional product leader do?

The same job a VP of Product or CPO does, scoped to the hours the stage needs: strategy, prioritization, discovery, delivery rhythm, and the hard calls, embedded in your team rather than advising from outside it.

How is Cospree different from an agency or consultancy?

Cospree is one senior operator, not a bench. The person you talk to is the person who does the work, and the model is built to make itself unnecessary: we set up the operating model, the team, and the metrics so the product runs without us.

What happens when you leave?

That is designed in from day one. Arches are raised on centring; once the keystone sets, it comes down and the arch stands on its own. Every engagement ends with your team owning the strategy, the cadence, and the numbers.

How do engagements usually start?

Small and reversible. AI-native founders usually start with a fixed-scope product sprint. Established B2B SaaS teams usually start with a two-week AI integration audit. Both can grow into an embedded retainer if the fit is right.

How do I start a conversation?

The fastest path is the booking link in the header: a thirty-minute call, direct with the person who would do the work, no deck. If you would rather write first, use the email link in the footer, with a line about the product and the problem.

What does an engagement cost?

Sprints are fixed scope, typically from $25K to $50K depending on surface area. Audits are a fixed fee. Embedded retainers typically run $10K to $15K per month for two to three days a week. Exact numbers on the first call, once we both understand the problem.

Who is behind Cospree?

Cospree is a senior product practice led by an operator with ten years in B2B SaaS and a zero-to-scale AI product behind them. You work directly with that person, not a rotating team. Cospree stays small on purpose: senior, embedded, and built to make itself unnecessary.

Senior by default.

Cospree is a senior product practice, not an agency and not a bench. The person who scopes your work is the person who does it: an operator with ten years in B2B SaaS and an AI product taken from nothing to real scale. Embedded when it matters, out of the way when it does not, and built to leave your team owning the result.
