Venture Building

Venture builder vs accelerator vs incubator

Accelerators, incubators and venture builders are routinely grouped together and they are not the same. They engage at different points, contribute different things and end in different places. Choosing the wrong one costs a founder time they do not have.

The three models are often listed as alternatives to each other. They are better understood as three different answers to three different situations. An incubator helps an early team survive. An accelerator helps an existing company learn faster. A venture builder creates the company in the first place.

Incubators

An incubator provides an environment: workspace, shared services, mentoring, and sometimes a small grant or investment. Its engagement point is a founding team that already exists and has an idea. Many are attached to universities, local authorities or corporates. The support is broad rather than deep, and the relationship is usually non-exclusive and open-ended.

It suits a team that needs runway, structure and a network, and that already knows what it is building.

Accelerators

An accelerator runs a fixed-length cohort programme, typically three to six months, ending in a demo day where companies pitch to investors. It usually invests a small amount for a small equity stake. Its value is compression: mentoring, curriculum and peer pressure applied to a company that already has a team and, ideally, a product.

The programme ends. After demo day the company is on its own, with whatever it raised and whatever it learned. That is by design, and it is the most important thing to understand about the model.

Venture builders

A venture builder starts before the company does. It identifies the opportunity, validates it, assembles the founding team, builds the product, funds the early rounds and stays involved through launch, acceleration and scale. There is no cohort and no end date. The capabilities a startup needs - strategy, talent, brand and product, technology, go-to-market, capital, growth - are held permanently and deployed venture by venture.

It suits a domain expert with an opportunity and no company, a founder who wants operational partnership rather than only capital, or a corporate looking to create a venture outside its core. It does not suit a founder who wants to build alone.

Choosing between them

  • You have a company, a team and early traction, and need to raise: an accelerator is a reasonable fit.
  • You have a team and need somewhere to work and people to ask: an incubator will do the job.
  • You have identified an opportunity and need a company built around it: that is a venture builder.
  • You are a corporate with IP or market access and no delivery vehicle: see corporate venture building.

One question separates the three faster than any brochure: what happens the day after the programme ends? For an accelerator there is a defined answer and a defined date. For a venture builder there is neither, because the relationship is the company.
