How a Climate Tech Company Raised $4.8M Under Reg A+

Why Reg A+ changes the marketing math

Reg A+ lets non-accredited investors participate at scale and allows general solicitation, so the constraint is not eligibility — it is attention and cost per invested dollar. With a longer campaign window, the objective shifts from a single launch spike to a durable acquisition channel.

We built for cost per investor, tracked weekly, with channels cut or scaled on that number alone.

The channel mix that worked

Three channels carried most of the raise.

• Paid newsletter placements in finance, investing, and sustainability publications — the highest-intent source by a wide margin
• Segmented outreach to investors in the database with prior climate or energy participation
• Retargeting across Meta and YouTube against the founder's mission video, which outperformed product creative roughly two to one

Investor relations as an acquisition channel

Monthly investor updates went to everyone on the list — investors and non-investors alike. Recipients who had not yet invested saw milestone progress in real time, and a meaningful share converted on the third or fourth update rather than at first contact.

Existing investors who received consistent updates were markedly more likely to add to their position during later milestone pushes, which is where the 18% repeat-capital figure came from.

The compliance guardrails

Every piece of outreach ran through offering-circular-consistent language, with testimonial and forward-looking-statement rules applied before anything shipped. On a multi-quarter Reg A+ campaign, review discipline is what keeps the channel mix scalable instead of fragile.
