At this level you can afford equipment, a small team and a longer runway, but every rupee still needs a clear purpose. Each idea has a full page with capital ranges, launch steps and sources.

What these ideas have in common

Most ideas in this band carry a physical or clinical element that drives up cost. Devices, vehicles, robots, labs and trained field teams appear often. Echocamp runs handheld echo screening camps for schools and employers. Sortcount puts cameras in dry-waste sorting centres to measure recovery shift by shift. Algaepond grows spirulina beside ethanol distilleries using their fermentation CO2.

Launch times are longer than for cheaper ideas. Many take six to twelve months, and health devices or biotech products can take eighteen months or more because of approvals.

How to choose

Here's what I'd do before anything else -

• Map where the money goes. Know which part of the range covers equipment, people and runway.
• Check for approvals, such as medical device or drug rules, that could delay your first sale.
• Is there a first step that costs less than the full plan, such as a pilot site or a service version? There usually is, and it's the smarter place to start.
• Use the free validation kit on each page to show investors real buyer demand before you raise.
