About Hero Section

Who we are, why we do it, and how we turn ideas into repeatable growth.

A growth practice for product-first B2B tech & SaaS.

We are a small, senior team building pragmatic growth engines — paid, SEO, outbound and experimentation — for early-stage B2B tech companies. Tacticalism exists to take the guesswork out of growth and give founders repeatable playbooks they can run or hand off.

Name Origin Section

Why "Tacticalism"?
What's the idea behind the name?

"Because strategy without tactics is just a good idea; tactics without strategy are busywork."

We combine product-aware strategy with short, surgical tactical experiments — think "strategy with a doer's muscle." The name reflects our belief: plan for scale, but measure in weeks, not quarters.

What We Do Section

What do we actually do?

We validate, build, and scale marketing systems that create paying customers.

Motivation Section

What motivated us to start Tacticalism?

A long list of "almosts" and a pattern.

Tamilselvan built and ran growth marketing for multiple SaaS firms and kept hitting the same wall:

Fuzzy positioning

Leaky funnels

Ad budgets wasted on unvalidated experiments

After leading growth at scale (DataDriven, Commenda), he realized founders needed a compact team that could plan, execute, and prove growth faster.

Tacticalism is that team: fewer meetings, clearer experiments, and 80% repeatable systems, 20% calculated experiments.

Founder Profile Section

Who is Tamilselvan?

Head down in growth, head up in strategy.
