Ask HN: Advice on Solo Launching

I have built a pipeline that takes construction documents as PDFs, extracts out the floor plans.

It extracts out BIM data from the plans at pixel accuracy producing data on walls, floors, windows and doors accurately.

It also generates 3D impressions and a brief 10s 3D video of the floor plans.

I have had multiple discussion to build within a company already solving the same problem but not closed a deal yet and considering taking it to the market as a solo founder.

I am outside the UK and USA and was seeking a founder for market access and future fundraising.

What is the best advice on how to go to market as a sole founder?
