The Token Company (YC W26) offers a compression middleware for pre-processing inputs to cut down LLM costs, latency and to allow more context into prompts with improved LLM performance and accuracy. Compression is useful for teams building LLM powered products and looking to maintain a large context, reduce inference costs, and improve model performance. In benchmarks, we have been able to reduce 66% of input tokens with +1.1% improved accuracy by removing the least significant tokens from prompts. The Token Company offers the model via an API. The prompt is first passed to the compression API, the compressed result can then be given to an LLM model of choice. The process enables significant token savings with improved context handling and model understanding.

Every small business is a big deal. SMBs have a major impact on the lives of their owners, as well as the macroeconomic success of their communities and national economy. Despite their significant impact, these businesses often lack access to tools and resources, leaving them vulnerable. As a result, very few end up making it. Apron is focused on helping more small businesses make it. The biggest threat to small business is cash flow, often stemming from a gap between the demand payments put on owners and the aptitude to make the payments effectively. At Apron we are closing the gap by digitising and simplifying the payments process. Whether capturing invoices, enabling collaboration for approvals, or combining long lists of invoices into one simple batch pay solution, Apron is your Powertool for Payments. Over time Apron will enable business owners to coordinate all outgoing and incoming payments, streamlining time and effort so you are freed up to focus on the business as a whole. By flipping payments from painful to powerful, Apron is amplifying the next generation of economic drivers. Apron Your Business Paid For
